3.206 Fall and Rise of China: Battle of Shanggao

Last time we spoke about the Hubei-Henan Campaign of 1940-1941. In November 1940, a Central Hubei operation using multiple task forces aimed to exploit Chinese dispersal, achieving only local successes and no lasting territorial gains. The Japanese then tried again in late January 1941 with a major offensive into southern Henan. Despite concentrating a large force, the campaign failed strategically. After the Henan failure, Japan attempted to regain momentum in spring 1941 by attacking western Hubei around Yichang on the Yangtze. Despite an initial barrage and rapid early gains, Japanese forces became exposed in a narrow salient. The Chinese reorganized their river defenses and launched a converging counteroffensive, driving the invaders back and ending the engagement where it began, with the Japanese suffering heavy casualties and their westward push thwarted. #206 The Battle of Shanggao Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel where I cover the history of China and Japan from the 19th century until the end of the Pacific War. The year 1940 had brought a particular humiliation. In August of that year, Communist General Peng Dehuai had launched the Hundred Regiments Offensive — a massive, coordinated assault across North China that shattered Japanese rail and supply lines, embarrassed Imperial General Headquarters, and demonstrated that the Chinese were far from finished. Japan's response had been brutal, the infamous "Three Alls" campaign of reprisals across the countryside. But the damage had been done, and the attention of Imperial General Headquarters shifted northward. The autumn of 1940 had also seen the First Battle of Changsha, where the Japanese 11th Army under General Sonobe Yahachirō pushed south into Hunan Province expecting to overwhelm the Chinese defenders and finally deal a decisive blow to Chiang Kai-shek's armies. Instead, General Xue Yue — the "Tiger of Changsha" — had allowed the Japanese to advance deep into his prepared killing ground before counterattacking from multiple directions. The Japanese had been forced to retreat in disorder, and the front in Hunan and Jiangxi settled once again into sullen stalemate. It was in this atmosphere of frustrated ambition and strategic inertia that the seeds of Shanggao were sown. By February 1941, Imperial General Headquarters had decided to redeploy the 33rd Division — then garrisoned in the town of Anyi, in northwestern Jiangxi — to North China. The transfer was scheduled to begin in early April, and it made strategic sense: the north required reinforcement, and the front in Jiangxi had been quiet enough that one division could be spared. The problem was that the 33rd Division's departure would leave a gap in Japanese dispositions, and no significant offensive operation had yet been conducted to weaken the Chinese forces that would be left facing a thinned-out Japanese line. Lieutenant General Ōga Shigeru, the energetic commander of the Japanese 34th Division, saw opportunity in the window that existed before the 33rd departed. His division was concentrated around Xishan and Wanshou Palace, astride the Xiang–Gan Highway — the main road running westward through Jiangxi — and across that highway lay the town of Shanggao and the Chinese forces defending it. Ōga proposed exploiting the presence of both divisions for a coordinated strike: a sharp, limited offensive to crush Chinese field forces around Nanchang and the Jiangxi interior before the 33rd Division's train north. The 11th Army headquarters, now commanded by General Marube, endorsed a cautious concept — a "quick strike" with limited objectives. But the 34th Division's staff, energized by Ōga's ambition, had already run well ahead of this guidance. Large-scale requisitioning of coolies for logistics was underway; training exercises aimed at the specific terrain around Shanggao had been conducted; planning had progressed in far more detail than a "limited" operation warranted. This eagerness would prove to be the Japanese undoing before the first shot was fired. Chinese intelligence networks, always attentive to the movement of porters and the telltale preparations that preceded a Japanese offensive, quickly detected the scale of these preparations and reported them to General Luo Zhuoying, commander of the Chinese 19th Army Group. By the time the Japanese columns were forming up to march, Luo had already hardened his defenses and laid the groundwork for a trap. General Luo Zhuoying was not a passive commander. He served simultaneously as commander of the 19th Army Group and as Deputy Commander of the 9th War Zone — the latter post placing him directly under General Xue Yue, the victor of Changsha. Luo had spent the lull after Changsha doing what Chinese commanders across the theater had learned was essential: reorganizing, retraining, and above all improving the defensive architecture of his sector. The plan Luo devised for meeting the anticipated Japanese offensive was elegant in its simplicity and demanding in its execution. Rather than contesting the Japanese advance at the frontier, he would allow the enemy to push westward, yielding ground through three successive defensive lines while bleeding the attackers at every step. The first and second lines would slow the Japanese, exact casualties, and stretch their logistics. The third line — anchored at Shanggao itself — would be the killing ground. There, the Chinese forces would hold fast while other formations swung around the Japanese flanks and rear to close the encirclement. The Japanese, having marched deep into Chinese-held territory with their supply lines thinning and their flanks exposed, would find themselves surrounded rather than victorious. For this plan to work, each Chinese formation had to perform its role with discipline. The 70th Corps, deployed in the north along the arc from Shitou Street through Fengxin to Jing'an, would have to conduct a controlled fighting retreat — yielding ground but making the Japanese pay for it, never breaking and running. The 49th Corps would hold the southern flank and create conditions for flanking action. And the 74th Corps — General Wang Yaowu's elite formation, comprising the 51st, 57th, and 58th Divisions — would hold the final line at Shanggao and serve as the anvil upon which the Japanese advance would shatter. The 74th Corps was by 1941 one of the most battle-hardened formations in the Nationalist Army. It had fought at Shanghai in 1937, at Wuhan in 1938, and in the hills and valleys of Jiangxi through the years since. Its men knew the terrain around Shanggao. They had prepared positions in depth, studied the approaches, and rehearsed the defensive plan Luo had designed. When the Japanese came, they would be ready. Against the Chinese 70,000 — distributed across eleven divisions in four corps, with additional provincial security forces for local coverage — the Japanese would throw roughly 20,000 men: three major formations advancing in coordinated columns. The disparity in numbers was stark, but the Japanese had the advantages of offensive initiative, air superiority, and the formidable fighting quality that the Imperial Army had demonstrated throughout the war in China. The question was whether those advantages would be enough to overcome a prepared defense wielded by a commander who had invited the attack. The operational plan devised by the Japanese 11th Army called for three columns to converge simultaneously on Shanggao from north, center, and south — a classic encirclement concept that, if executed with precision, would catch the Chinese defenders in a tightening vice. In the north, the main force of the 33rd Division under Lieutenant General Sakurai Shōzō would drive westward from its bases around Anyi and Ganzhoujie, descending the Liao River valley to threaten the Chinese right flank and prevent the 70th Corps from interfering with operations in the center.In the center, Ōga's 34th Division would advance along the Xiang–Gan Highway — the direct route from Nanchang toward Shanggao — capturing the town of Gao'an along the way and pressing relentlessly westward until it reached the main defensive positions. This was the principal striking force, the column designed to crack open the Chinese defenses and seize the objective.In the south, the Independent Mixed 20th Brigade under Major General Ikeda would cross the Jin River and advance along its south bank, eventually swinging north to link up with the 34th Division and complete the encirclement of whatever Chinese forces remained in the Shanggao area. The plan was coherent on paper. But it contained a structural flaw so serious that, in retrospect, it is difficult to understand how the 11th Army's staff allowed it to proceed uncorrected. The success of any converging operation depends on synchronization — on each column hitting its objectives on schedule and maintaining communication with the others so that each can react to developments on the other prongs. Yet the 11th Army headquarters made no recorded effort to coordinate the 33rd and 34th Divisions before the battle began. There was no forward command post established to oversee the operation. General Marube remained at Hankou, hundreds of miles to the north, throughout the battle — as remote from the fighting as a Tokyo bureaucrat. Operational decisions were left entirely to the individual divisions, with no mechanism to coordinate their actions if something went wrong. Something was going to go wrong. Luo Zhuoying had seen to that. On the morning of March 15, 1941, all three Japanese columns stepped off simultaneously, advancing into the misty hills and rice paddies of northwestern Jiangxi. In the north, Sakurai's 33rd Division moved briskly from Anyi toward Fengxin. The town fell by noon, and the division pressed westward in good order. The Japanese infantry moved confidently along the Liao River valley, experienced soldiers who had fought across China and had no particular reason to expect what was coming. The Chinese 70th Corps gave ground — as it had been ordered to — but did so on its own terms, occupying and then abandoning successive pieces of high ground along both banks of the river, making the Japanese advance uncomfortable and costly. Gradually, almost imperceptibly, the 33rd Division was being drawn forward into terrain that favored the defender. By March 18 and 19, the 33rd Division had pushed all the way to Guzhu'ao and Huamenlo — a considerable advance, but one that had taken the division far from its base at Anyi. And it was here, far from support and with flanks increasingly exposed, that the Chinese blocking forces closed in. Chinese infantry, who had been waiting in prepared positions in the high ground overlooking the river valley, launched coordinated counter-attacks that struck the 33rd Division from multiple directions. The fighting was fierce and costly. In two days of close combat, the division suffered more than 2,500 casualties — a grievous toll that represented a significant fraction of its effective strength. The northern column had been stopped dead. On March 19, Sakurai ordered the 33rd Division to reverse course. By March 23, after four days of painful withdrawal under pressure, it had pulled back to Anyi — the same place it had started. The northern prong of the Japanese offensive had accomplished nothing except the loss of thousands of men. In the south, the Independent Mixed 20th Brigade had a rougher start. Its initial attempt to cross the Gan-Jin river junction at noon on March 15 was repulsed by Chinese defenders, and it was only under cover of darkness that the brigade managed to force a crossing. Once across, it moved westward along the south bank of the Jin River, but progress was slow and contested. A detachment — the Gan River Detachment — ran into fierce resistance from the 26th Division of the Chinese 49th Corps on March 19. The brigade's main body meanwhile fought its way through the 51st Division of the 74th Corps, but the 107th Division and elements of the 51st managed to contain the advance at the Laichunling–Zhutoushan line. On the night of March 20, the main body of the 20th Brigade crossed the Jin River at Huifu to link up with the 34th Division — but a portion of its troops, cut off on the south bank, was destroyed by Chinese forces. The southern column was across the Jin River, but it had taken losses and was already engaged in ways its planners had not anticipated. In the center, the 34th Division fared best in the early going. Ōga's division moved westward from Xishan along the Xiang–Gan Highway on March 16, and by the 17th had captured Gao'an — a meaningful early success. The Chinese 74th Corps, executing Luo's plan faithfully, dispatched only screening forces east of the Tangpu River to slow the Japanese advance rather than contesting it decisively. The main body of the 74th Corps fell back to the third-line positions at Sixi, Guanqiao, and Tangpu, preparing the killing ground that Luo had designated. Simultaneously, the 26th Division and most of the 105th Division from the 49th Corps were shifted across the Gan River to operate south of the Jin River on the Japanese left flank, and the 72nd Corps was ordered to maneuver on a wide envelopment around Daxia and south of Ganfang. By March 20–21, the 34th Division had pressed forward to attack the Chinese positions at Sixi and Guanqiao. Ōga's men were confident — they had taken Gao'an, they were moving, and the objective of Shanggao lay within reach. But as the division pushed toward Shangjijia, it ran squarely into the 57th and 58th Divisions of the 74th Corps, fighting with a tenacity that told the Japanese plainly enough: this was where the Chinese intended to stand. The week of March 21–24 brought the battle to its crisis. The 34th Division hammered at the Chinese positions defending Shanggao itself, while on the flanks, the fighting took on a character that neither side had entirely anticipated. On March 21, General Wang Yaowu — commanding the 74th Corps from his headquarters in Shanggao — decided it was time to do more than absorb Japanese blows. He ordered General Li Tianxia to clear Japanese forces from the south bank of the Jin River and advance on Gao'an, with the aim of cutting the 34th Division's supply line and threatening its rear. It was an aggressive move, and if it had worked, it might have produced a decisive result earlier than history would record. It did not work — at least not immediately. That very evening, the Independent Mixed 20th Brigade, which had been reorganizing after the chaos of the river crossing, launched a powerful offensive at dawn on the 22nd. Li Tianxia's lead elements had barely set out from Shitou Street when they collided head-on with the main force of the 20th Brigade, which had crossed back from the north bank of the Jin River. The Japanese thrust was coordinated and aggressive: one column circled wide to attack Lazhu Mountain; another swung south of Hu Family west of Shitou Street to strike Li's division in the flank and rear; and nine aircraft with four artillery pieces bombarded the Chinese positions from north to south. Li's division could not hold against this convergent assault and fell back to the high ground southwest of Shitou Street. Wang Yaowu reacted quickly. He ordered Li's main body to wheel left to face the new threat and simultaneously dispatched the Army's Field Supplementary Regiment — held in reserve near Yintang — on a forced march to Huayang to block the Japanese westward drive. This regiment, racing down roads strafed by nine enemy aircraft, covered 15 li per hour and seized Huayang and the high ground to its northeast by around seven in the morning. By nine, the 20th Brigade arrived in strength and — supported by more than ten aircraft — launched a fierce assault on the regiment's positions. The regiment's officers and men held firm, taking heavy casualties but refusing to break. Frustrated at Huayang, the 20th Brigade shifted its effort to the Kuang Family area, linking up with over a thousand men who had crossed from Baichetou to the south bank and pushing along the river toward Xiongfang in an attempt to outflank the Chinese left wing. The Supplementary Regiment sent its 1st Battalion with a mortar company to meet this threat, and the two forces met in a fierce engagement. When the Japanese reinforced their assault and deployed incendiary bombs and poison gas, Xiongfang fell by early afternoon — but Li Tianxia immediately sent two regiments from his right flank to take it back, and by midnight the position was in Chinese hands again. Shitou Street and Jigong Ridge were simultaneously recaptured. The Independent Mixed 20th Brigade now found itself in an increasingly uncomfortable position, fighting with the Jin River at its back and the initiative slipping away. Meanwhile, the main event was being fought in the rubble and ridgelines around Shanggao itself. From March 22 to 25, the 34th Division and whatever remnants of the 20th Brigade could contribute threw themselves repeatedly at the defensive line anchored on Stone Arch Bridge, Xia Po Bridge, Xu Lou, Pan Family Bridge, Cloud Head Mountain, and Lei Family Mountain. This was not the fluid, mobile warfare that the Japanese had envisioned but brutal, grinding attritional combat for individual strongpoints and ridgelines, with positions changing hands multiple times in a single day. The Japanese air arm was deeply involved. Ōga's division had close air support that could operate even in poor weather, and Group 3 of the Japanese Air Force hammered the Chinese positions with sustained effort. On the morning of March 24, after the 34th Division fed in more than 3,000 additional troops transferred across the Jin River, the Air Force dispatched over seventy aircraft that dropped more than 1,700 bombs, largely destroying the defensive positions of Liao Lingqi's division. The Japanese exploited the resulting chaos and twice broke through gaps in the line — but were driven out each time by Chinese counterattacks. At noon, enemy aircraft bombarded in relays and Japanese infantry broke through at Xia Po Bridge. It was at this moment that Li Hanqing, commanding the Chinese infantry defense in that sector, did what officers throughout history have done when systems fail and only personal example can stem the tide: he personally led his officer cadre in repeated counter-attacks, hand-to-hand fighting in the rubble until the Japanese were finally expelled. By this point, the 34th Division's offensive capacity was nearly spent. At the same time — and this was the critical shift that would determine the battle's outcome — General Luo Zhuoying recognized that the moment to spring the trap had arrived. The northern column had already been broken and sent reeling back toward Anyi. The southern column was pinned against the Jin River with its back to the water. The central column was bled white against the defenses of Shanggao. Luo now ordered all his armies to close in from multiple directions. On the morning of March 22, he had already begun revising his orders; by noon on the 23rd, the forces of Liu Duoquan and Li Jue had occupied Shitou Street, Guanqiao Street, and Yanggong Market, pressing on Huifu and Gaoyao. The encirclement of the 34th Division was not yet complete, but its shape was unmistakably forming. By March 25, the 34th Division knew it was in mortal danger. Surrounded on three sides, its ammunition running low and its casualty lists growing by the hour, the division urgently appealed to the 11th Army for rescue. The message that arrived in Hankou was a shock. General Marube and his staff, who had remained at their distant headquarters throughout the battle without establishing a forward command post, had not properly grasped the scale of the disaster unfolding in Jiangxi. The lack of coordination between the 33rd and 34th Divisions — the structural flaw that had been built into the operation from its conception — had allowed Luo Zhuoying to defeat each column separately, and now the central column faced annihilation. The 11th Army responded in a scramble. Chief of Staff Kinoshita was dispatched by aircraft to Nanchang with Operations Staff Officer Lieutenant Colonel Yamaguchi and Captain Ōne to organize a relief operation. The 33rd Division — barely recovered from its own battering in the north — was ordered to sortie immediately and fight its way to the 34th Division's relief. Sakurai organized his battered 33rd Division into three rescue columns. Infantry Brigade Commander Araki Shōji took the right column, leading Infantry Regiment 215 with one mountain artillery battalion. Infantry Regiment 214 formed the left column. The divisional commander himself led the central column with the main divisional force. On March 24 and 25, all three columns sortied from strongpoints at Niuxing, Fengxin, and other positions, attacking across the Wuqiao River and through Cunqian Street toward Tangpu and Guanqiao. The relief operation brought the battle to its most complicated moment. On the morning of March 25, the 33rd Division launched a fierce assault on the forces that Luo Zhuoying had positioned to tighten the encirclement from the north — striking Zhang Yanchuan's division at Kengkou Leng, Jiezipo, and Nancha Luo. Zhang's division, struck simultaneously from the front and rear, withdrew at dusk to near Tu Di Wang Temple, where it linked up with Tang Boyin's division. What happened next became one of the most controversial decisions of the entire battle. Zhang Yanchuan was serving as deputy army commander in the absence of Li Jue from the front. Surveying the situation — his own division under heavy pressure, the 33rd Division's relief columns pushing aggressively — Zhang concluded that the position was untenable. On his own authority, without authorization from Luo Zhuoying or any superior commander, he withdrew both his own and Tang Boyin's divisions to Fenghuang Market and Zhuangfang. The consequence was immediate and severe. The withdrawal opened a corridor through which the 33rd Division entered Guanqiao and linked up with the encircled 34th Division. An encirclement that had taken days of blood and sacrifice to construct was torn open by a single unauthorized decision. Luo Zhuoying, when he received word of Zhang's withdrawal the following morning, was furious — but he could not change what had already happened. He could only adapt. The breakout itself was an ordeal. A portion of the 34th Division that attempted to escape to the east was intercepted near Huifu by a division of the 49th Corps and lost roughly half its strength before being compelled to turn back. The main body ultimately broke out on March 27, withdrawing in march order that told its own story of disaster: headquarters, baggage, artillery, casualties, field hospital, rear guard — all moving in what the records describe as "a wretched state." On the night of March 27, Japanese troops escorting the 34th Division's field hospital — a field artillery company of the 8th Battery — were completely annihilated in a Chinese night attack. When the division reached Longtuan Xu on March 28, the stretcher-bearer column carrying the wounded stretched some seven to eight kilometers along the road. That same day, the 33rd Division's Infantry Regiment 214 finally made contact with the 34th Division's headquarters, completing what amounted to a rescue of men who had already endured their defeat. The 33rd Division's mountain artillery batteries exhausted their entire ammunition supply covering the retreat and required emergency aerial resupply drops to continue. The 34th Division limped back to its original garrison on April 2. Despite the setback caused by Zhang Yanchuan's unauthorized withdrawal, Luo Zhuoying did not abandon his design. Assessing his situation on the morning of March 26, he found reason for cautious optimism: Wang Yaowu's army was still making progress at Shanggao; the Japanese south of the Jin River had largely been cleared; and Sichuan Army and Northeastern Army units that had been moving to reinforce the battle had now reached the field, meaning Chinese forces retained significant numerical superiority. He resolved to execute a second encirclement. At nine in the morning of March 26, Luo issued strict orders: Zhang Yanchuan's and Tang Boyin's divisions were to immediately comply with their original orders and block the enemy near Guanqiao; Yu Chengwan's division was to attack northward via Pan Family Bridge; Liao Lingqi's and Song Yingzhong's divisions were to press toward Guanqiao with full force; Wang Kejun's division was to strike the enemy's flank and rear east of Guanqiao; Fu Yi's division was to advance south of Jiang Family Isle; and Chen Liangji's division was to swing southeast via Changpu to complete the enemy's destruction. The second ring was being drawn. On March 28, as the 34th Division's battered column trudged eastward toward survival, Wang Kejun's division advancing from Yanggong Market moved to intercept it. The Chinese occupied high ground north and south of Yanggong Market and along Mozi Ridge, and what followed was a grinding all-day battle that fixed the Japanese column at the Xiama Bei–Huxing Ridge line. Part of the 20th Brigade, moving up from Gao'an to assist the withdrawing 34th Division, was blocked near Long Tu Market. Liao Lingqi's division pursued the enemy rear guard to the Changling–Manmei high ground, where the fighting erupted with renewed intensity. At noon, part of Li Tianxia's division arrived and deployed along the Shangluoxiang–Shanyuan–Fangtounao line to harass the Japanese right flank; part of Yu Chengwan's division reached Longxing Mountain and outflanked Guanqiao Street from the south. The surviving Japanese defenders in Guanqiao withdrew into the town for a last stand, and after Liao's division pressed the assault, street fighting raged until five in the afternoon, when over 600 defenders were annihilated. Over 2,000 troops of the Independent Mixed 20th Brigade conducted a fighting withdrawal from Long Tu Market and Yanggong Market, covered by Japanese aircraft bombing to shield the 34th Division's retreat. By noon on March 30, the Japanese had abandoned both strongpoints and scattered northeastward. One group of over 600 men fled directly into the main positions of Zhang Yanchuan's division — an ironic fate, given Zhang's earlier withdrawal — and were largely annihilated. The encircling forces had been essentially dispersed, and the two pursuit columns now pressed forward under the overall direction of General Xue Yue, who had assumed personal coordination of the chase. On March 27, Luo Zhuoying — confident that victory was secured — issued a general order for a final offensive and announced substantial cash rewards to his troops: prizes offered for the capture of Japanese officers, artillery pieces, regimental colors, and other materiel. The rewards were both a practical incentive and a mark of how far the battle had tipped. By midnight on March 31, Chen Hongshi's advance column had recovered Gao'an; Wang Tiehan's division had recovered Xiangfu Guan. On April 2, the divisions of Zhang Yanchuan and Song Yingzhong recovered Fengxin; that afternoon Wang Tiehan's division took back Xishan and Wanshou Palace — the very base from which the 34th Division had launched its offensive. By April 3, the pursuing armies had reached the vicinity of Dacheng and Ganzhoujie. On April 8 and 9, the 70th Corps recovered the outpost strongpoints around Anyi before halting operations. The Japanese had retreated into their original positions and were defending from prepared terrain. The pursuit was over. The Battle of Shanggao had lasted nineteen days and nights. No battle of the Second Sino-Japanese War was ever free of the fog of competing claims, and Shanggao was no exception. On March 29, before the pursuit had even concluded, Luo Zhuoying telegraphed Chiang Kai-shek with his accounting of the victory. His numbers were dramatic: Major General Iwanaga, the Japanese infantry commander, killed; regimental commander Colonel Hamada, killed; over 15,000 Japanese killed or wounded in total. Chinese losses, Luo reported, exceeded 20,000. Ten guns, over a thousand rifles, and numerous machine guns had been captured. His superior, General Xue Yue, was skeptical. In a telegram to Chiang Kai-shek on April 5, Xue reduced Luo's numbers by twenty percent, reporting 12,520 Japanese killed or wounded and 14 prisoners captured. The discrepancy between two Chinese commanders reporting on the same battle speaks to the difficulty of battlefield accounting in any era, and suggests something of the competitive pressures that shaped how Chinese commanders reported their victories to Chongqing. The official Chinese histories, compiled after the war in the History of the War of Resistance, reported approximately 15,000 Japanese killed or wounded, 17 prisoners taken, and significant quantities of captured materiel: 6 mountain guns, 1 mortar, 24 light machine guns, 408 rifles, 24 grenade launchers, and over 111,717 rounds of various ammunition. Chinese casualties, by the same records, were 17,119 killed or wounded and 2,814 missing. Japanese records for the battle do not survive — a consequence of the wholesale destruction of Imperial Army documentation at the war's end. Contemporary scholars, working from other sources, estimate actual Japanese combat losses at approximately 5,500 killed and wounded. This is substantially lower than the Chinese claims, as was nearly always the case in the war, but represents a significant defeat by any measure: roughly a quarter of the force committed, many of them veterans impossible to replace. Chiang Kai-shek subsequently awarded the victorious Chinese units a commendation prize of 150,000 yuan — a substantial sum that marked the battle's significance in Nationalist eyes. The outcome at Shanggao was not accidental. Several interlocking factors combined to produce a Chinese victory, and each deserves consideration. The most fundamental was Luo Zhuoying's defensive plan. The decision to trade space for time — to absorb the Japanese advance through three successive defensive lines rather than contest the frontier — required both tactical confidence and a willingness to accept initial setbacks that could easily be misread as defeat. Chinese forces had to give ground, and they did. They had to suffer through the early days of Japanese advance without breaking and running, drawing the enemy forward and allowing the encirclement to take shape. That they largely succeeded in executing this plan reflects the improving quality of the Nationalist Army by 1941: better trained, better led at the operational level, and — critically — equipped with a strategic design that matched the actual balance of forces. The defeat in detail of the Japanese columns was equally important. By neutralizing the 33rd Division in the north before it could contribute to the central effort, and by pinning the 20th Brigade against the Jin River with its back to the water, Luo's forces ensured that the 34th Division faced the third-line defenses essentially alone — outnumbered, overextended, and unsupported. The Japanese operational concept had been a three-pronged convergence; what actually materialized was a single exhausted division hammering at a prepared defense while two other columns were rendered ineffective. The absence of coordination within the Japanese 11th Army was a gift that kept giving throughout the battle. No forward command post. No mechanism for the divisions to adjust their operations in response to each other's situations. No ability to recognize, in real time, that the northern column was being destroyed and redirect resources accordingly. General Marube's decision to remain at Hankou while his men died in Jiangxi was not merely an administrative failure; it was an operational catastrophe. Japanese commanders acknowledged this failing explicitly after the battle, but the acknowledgment changed nothing for the dead. Zhang Yanchuan's unauthorized withdrawal — the single most consequential individual decision of the battle — ultimately prevented a complete annihilation of the 34th Division rather than affecting the battle's outcome. The 34th Division escaped; but it did so in a "wretched state," having lost enormous numbers of men and equipment. It broke out, not triumphed. The encirclement Luo had constructed was torn open, but the Japanese paid dearly for the breach. The consequences of Shanggao rippled outward in ways that shaped the subsequent course of the war in central China. The transfer of the 33rd Division to North China — the original logistical rationale for the entire operation — was delayed by the division's involvement and subsequent losses at Shanggao. When it finally arrived at the Battle of Central Plains the following month, it did so on the eve of battle with no time for preparation or orientation, entering combat under severely disadvantaged conditions. The operation that was supposed to facilitate a smooth redeployment had instead damaged one of the two units involved and delayed the other. For the Chinese 74th Corps, Shanggao had an ironic consequence. The Japanese 11th Army, following the battle, formally designated the 74th Corps as a priority target — a "standing enemy" and directed its forces to seek out and destroy it in future operations. At the First Battle of Changsha that September, the 11th Army specifically oriented its forces against the 74th Corps, a testament to the lasting impression that corps's fierce resistance at Shanggao had made on its adversaries. The compliment of being specifically targeted by the enemy was one the 74th Corps had earned in blood at Shanggao's ridgelines and shattered bridges. More broadly, the battle was widely regarded at the time, and has been regarded since, as one of the most significant Chinese tactical victories of the first four years of the War of Resistance. Its significance lay not only in the casualties inflicted — those were contested and probably inflated in the Chinese records — but in what it demonstrated. The improving tactical and operational competence of the Nationalist Army was on display. The deliberate defense, the layered withdrawal, the coordinated encirclement — these were not the operations of an army that had been fighting desperately for survival since 1937 and had learned nothing. They were the operations of an army that had studied its defeats and adapted. Shanggao did not change the strategic situation in China. The front in Jiangxi remained where it had been; the Japanese still occupied Nanchang and the major cities; Chiang Kai-shek was still in Chongqing and the war was still far from over. But it demonstrated something important: that the Chinese Army, given capable commanders, a sound plan, and the discipline to execute it, could do more than survive Japanese offensives. It could reverse them, encircle them, and pursue them back to where they came from.

In March–April 1940, Japanese forces attacked Shanggao with a limited, multi-pronged plan. Chinese troops used elastic defense and coordinated counter-moves, turning initial advantages into a trap. After intense fighting and air strikes, a coordinated encirclement and timely breakout routed the Japanese, forcing retreat despite their numbers in a costly battle.

3.205 Fall and Rise of China: Hubei-Henan Campaign 1940-1941

Last time we spoke about the One Hundred Regiment Offensive. During Phase Three of the One Hundred Regiment Offensive, CCP forces in the Taihang/Jizhong area emphasized strongpoint attacks and transportation warfare. Rather than trying to defeat Japanese units head-on, they used tactics such as night raids and ambushes to disrupt Japanese supply routes and communications. The underlying goal was to make Japanese logistics unstable, weakening their ability to maintain control and conduct effective operations. After CCP successes, the Japanese responded with large-scale "mopping-up" operations beginning October 6. As the Eighth Route Army continued resisting, it adopted flexible methods to counter the Japanese sweeps, especially rapid repositioning and targeted ambushes. One notable action described involves an ambush of a Japanese convoy that caused substantial enemy losses, demonstrating how disrupting enemy mobility could blunt the effectiveness of larger Japanese operations. Overall, the situation remained fluid, with both sides continually adapting their tactics in an ongoing contest for control across occupied North China. #205 The Hubei-Henan Campaign of 1940-1941 Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel where I cover the history of China and Japan from the 19th century until the end of the Pacific War. By 1940, the war had settled into a grueling stalemate, with Japanese troops occupying vast swathes of central China, including parts of Hubei, but facing persistent Chinese guerrilla and conventional resistance that prevented total consolidation. In the aftermath of the Battle of Zaoyang in the summer of 1940, Japanese forces had secured the key cities of Yichang and Shashi along the middle reaches of the Yangtze River. Yet Chinese Nationalist troops of the Fifth War Area retained firm control over the vital territories east and west of the Xiang River. Their defensive lines formed a broad arc stretching from the southwest of Yuan'an through Jingmen, north of Zhongxiang, and the rugged foothills of the Dahong Mountains, extending northwest to Suixian. These positions straddled both banks of the Xiang River, anchored on the right by the Wudang Mountains and on the left by the Tongbai range. Working in close coordination with guerrilla detachments operating in the southeast, Chinese units repeatedly harassed the Japanese garrisons that had pushed into Yichang. The constant pressure on the enemy's flanks left the Japanese forces in Yichang and Shashi dangerously exposed and hemmed in, unable to expand or consolidate their gains. To the Japanese high command, this situation had become an intolerable thorn that demanded immediate removal. Under Generalissimo Chiang Kai-shek, the Chinese Nationalist government faced severe strains as the war with Japan escalated. Its problems were not only military, but also political and economic. Deep ideological and territorial rivalries with the CCP meant that efforts to present a single front were constantly undermined. Although the two sides officially formed a United Front in 1937, earlier violence and competition, such as the 1927 Shanghai Massacre and the CCP's Long March of 1934 – 1935 had left distrust and strategic differences in place. As a result, Nationalist resistance was harder to coordinate than it would have been under full unity. Meanwhile, the CCP strengthened its position in northern China by expanding rural strongholds. Through land reforms and the use of guerrilla warfare, the communists were able to win local support and apply pressure to Japanese forces in ways that often did not require large, conventional armies. This strategy also drew influence and manpower away from the Nationalists' more traditional, state-centered military structure. Economically, the Nationalists were squeezed from multiple directions. The loss of China's coastal industrial regions to Japanese occupation forced the government to rely heavily on the interior, with Chongqing becoming a key base. That geographic shift left the administration more vulnerable to shortages of critical supplies, especially raw materials, fuel, and modern weapons. On top of wartime disruption, the global Great Depression intensified fiscal and logistical difficulties, limiting how quickly and effectively the Nationalists could mobilize resources for large-scale operations. By late November 1940, these weaknesses intersected with renewed Japanese pressure. Japanese commanders were also concerned about the possibility of a major Nationalist push, particularly fears of a counteroffensive by the Thirty-first Army Group under General Tang Enbo. Determined to break the stalemate, the Japanese launched a major offensive in late November 1940. Preparations had begun in earnest early that month. Engineers repaired and expanded highways and bridges, constructed new defensive works and airfields, and stockpiled vast quantities of rations, ammunition, steel-hulled boats, and rubber rafts in the Zhongxiang area. Five regiments were concentrated near Zhongxiang, while additional troops east and west of the Xiang River brought the total strength to more than three divisions. Along the Suixian–Xiangyang Highway, Japanese forces were reinforced to divisional strength, supported by increased artillery and tank detachments. These meticulous measures left no doubt that the enemy was ready for a large-scale operation. By 23 November the Japanese had completed their deployments and moved into assault positions. The Japanese forces assigned to the Central Hubei Operation were placed under the overall command of Lieutenant General Waichirō Sonobe, who directed the campaign from his headquarters in Wuhan. Sonobe's 11th Army drew on a broad mix of formations, combining units from the 3rd, 4th, 15th, 17th, 39th, and 40th Divisions. The offensive backbone for the thrust into central Hubei province was reinforced by the 18th Independent Mixed Brigade, which helped supply the infantry strength needed for sustained fighting across difficult ground. In practice, this multi-division structure reflected the 11th Army's key mission in the region, acting as the main Japanese formation after the earlier Battle of Zaoyang and it emphasized coordinated divisional advances supported by attached brigades and specialized elements, including limited armored capabilities. In terms of manpower, the Japanese force is commonly estimated at roughly 40,000 to 50,000 troops. This strength included several infantry regiments and artillery batteries, along with only limited armored elements rather than a fully armored formation. Because the operation depended on finding and exploiting opportunities quickly, it was supported by aerial reconnaissance and bombing carried out by the 3rd Air Brigade operating in central China. Infantry units formed the majority of the fighting power, while artillery was used to provide suppressive fire during advances. Air support, meanwhile, was intended to help identify and target Chinese positions—particularly along important riverine and rail corridors, where disruptions could slow resistance and complicate Chinese reinforcement or retreat. To manage the operation across varied terrain and combat tasks, Sonobe's command used smaller combined formation often described as task forces, that could operate with some flexibility. Among them were the Kayashima Force, commanded by Major General Koichi Kayashima of the 18th Independent Mixed Brigade, consisting of the entire brigade reinforced by elements of the 40th Division. The Muragami Force, under Lieutenant General Keisaku Muragami, commander of the 39th Division, which included the full division plus supporting non-infantry units. The Hirabayashi Force, led by Lieutenant General Morito Hirabayashi of the 17th Division, formed from detachments of the 17th and 15th Divisions.The Kitana Force, commanded by Lieutenant General Kenzo Kitana of the 4th Division, incorporating portions of the 4th Division and the Kususe Armored Force. These four groups were deployed in parallel around Tangyang, Jingmen, Zhongxiang, and north of Jingshan. The Hanjima Force, commanded by Lieutenant General Fusataro Hanjima of the 3rd Division, positioned near Suixian along the Xiangyang–Hua Highway. This task-force approach helped tailor combat power to specific mission profiles—such as flanking movements, raids, or pressure on Chinese defensive lines—while keeping the overall campaign plan under a unified command. Equipment choices also reflected the tactical environment of Hubei. The Japanese units made use of Type 95 Ha-Go light tanks for reconnaissance and for anti-infantry roles, typically best suited to the reconnaissance, pursuit, and screening functions that were available even with constrained armor numbers. For fire support, the force relied on conventional artillery, including 75mm Type 90 guns for field engagements and 105mm howitzers for heavier bombardment where stronger explosive impact was needed. Together, these assets were intended to allow Japanese formations to maneuver around Chinese positions and apply pressure in rugged landscapes where rivers, roads, and rail lines often determined the rhythm of battle. Logistics were a decisive factor in whether the operation could sustain momentum. Sonobe's army depended heavily on existing transportation infrastructure, particularly rail lines radiating from the Wuhan hub toward forward areas such as Suizhou and Zaoyang. These routes were critical for moving ammunition, replacements, and other supplies closer to the front as the Japanese advanced. The campaign also used river transport along the Yangtze River, including motorized barges and steamers, to deliver supplies to units operating near waterways. However, reliance on these corridors came with risks: Chinese interdiction raids could disrupt shipments, forcing convoys to be escorted and increasing the time and resources required to keep the forward units supplied. Overall, this dependence on both rail and fluvial networks highlighted a central operational challenge, maintaining secure access to transportation arteries in contested territory so that the Japanese could keep fighting effectively rather than stalling as supplies dwindled. The Central Hubei Operation was driven by an intelligence assessment that Chinese troop movements were signaling preparations for a Nationalist counteroffensive. Acting on that interpretation, the Japanese began tightening plans and positioning forces early in the final days of November 1940. On 23 November 1940, the Japanese 11th Army under Lieutenant General Waichirō Sonobe began organizing for the offensive in central Hubei. In order to conduct a coordinated advance across the Han River, the army arranged its forces into five groups, each tasked with moving in a way that supported the broader pincer-style pressure on Chinese positions. The approach also reflected lessons drawn from the earlier Zaoyang–Yichang campaign earlier in 1940, when Japanese divisions had been able to cross the Han River at multiple points, such as Dangyang, Jiukouzhen, and Shayangzhen—to help secure access toward Yichang and the Yangtze route. Logistics were built around infrastructure the Japanese had already established during prior operations. The Hankou hub supported the 11th Army through arrangements that included munitions storage, medical facilities, and transport coordination. Supplies and reinforcements were moved using truck convoys and river crossings, while forward depots—such as those at Shayangzhen northwest of Hankou—provided additional capacity, including freight handling and field hospitals. Because the area was not secure, these supply points were also guarded against threats from guerrilla activity, which could disrupt communications and threaten personnel and equipment. Operationally, the offensive used limited artillery and air support, reflecting Japanese constraints and directives aimed at keeping the campaign short and avoiding commitments that could stretch units beyond their logistical reach. Instead of trying to grind down Chinese defenses through prolonged bombardment, the plan prioritized speed, reconnaissance, and focused disruption. Japanese intelligence preparation relied heavily on aerial reconnaissance over the Han River valley to locate Chinese positions and infer where resistance would likely concentrate. That information enabled Japanese units to coordinate select maneuvers, including converging pressure from different directions. Where river transport mattered, coordination with naval or riverine elements supported movement and resupply, with overall oversight connected to the China Expeditionary Army. Anticipating the coming assault, the Chinese Fifth War Area headquarters acted swiftly on instructions from the National Military Council. Orders were issued to the River West Army Group (30th and 77th Corps), the Right Army Group (44th and 67th Corps), and the Central Army Group (41st and 45th Corps) to employ a flexible defensive strategy: hold key positions firmly while committing the main strength to strike the enemy's outer flanks at the decisive moment. The 59th Corps was directed to advance toward the Xiangfan area, ready to reinforce operations on either bank of the river as the situation developed. As commander of the Fifth War Area, Li Zongren arranged the defense to meet a likely Japanese thrust along the Han River, particularly in the approaches to Wuhan and Yichang, following the wider stalemate that settled in after the 1938 fall of Wuhan. The Fifth War Area could draw on roughly 300,000 troops, though many units were understrength, and the overall readiness varied by locality. Among the formations Li Zongren placed in the most sensitive sectors was the 31st Army Group under General Tang Enbo, which Japanese planners had identified as a potential threat to Japanese intentions in the region. In keeping with the terrain and the limits on manpower, Li's defensive design relied heavily on natural barriers—most importantly the Han River itself—and on the defensibility of rugged ground. Forces were arrayed to hold or contest riverbank positions, supported by fortifications, trenches, and smaller auxiliary elements. Divisions such as the 44th were positioned with an eye toward slowing an enemy crossing and forcing the Japanese to fight for difficult approaches rather than moving rapidly. At the same time, irregular forces and prepared defensive works were used to complicate Japanese reconnaissance and to make it harder for the attacker to coordinate a clean operational flow. Strategically, Li Zongren leaned on elastic defense rather than attempting to win decisive battles at fixed lines. Regular units were supported by guerrilla-style harassment intended to strike Japanese vulnerabilities, especially supply and transportation, between forward bases and the front. Local operations, including actions coming from areas such as Xinyang, were designed to disrupt Japanese logistics in periods when the Nationalists were still managing shortages of ammunition and medical supplies. Militias in the inter-mountainous regions further reinforced this approach: instead of seeking costly frontal engagements, they concentrated on disruption, delaying movements, and making Japanese operations slower and more expensive. At dawn on 25 November the Japanese offensive began, with columns advancing along multiple axes. On the western Xiangyang front, more than 1,000 troops from Tangyang and over 3,000 from Jingmen struck Hengdian and Yanzhimiao, shattering the positions of the Chinese 30th Corps. Simultaneously, a column moving from Zhujiafu toward Tunglinling split into several detachments and drove deep northward into Liangshuijing, Xiajiazi, and Kuaihuopu. By nightfall the River West Army Group had regrouped along the line from Hengdian through Yanzhimiao to Kuaihuopu. On 26 November the Japanese reached Xianzhu. The following day they assaulted Liuhouji and Lijiatang in a day-long battle that ended in stalemate. At dusk the 30th Corps launched a powerful counterattack; the 27th and 31st Divisions dispatched raiding parties into the enemy's rear. Unable to withstand the pressure, the Japanese fell back toward Jingmen and Zhongxiang, pursued by Chinese forces that inflicted heavy losses. Along the Jingmen–Zhongxiang Highway the Japanese massed more than 3,000 troops to attack Changshoutian and Wangjiatian, encircling Changjiachi and Shahetian. The Chinese 149th Division withdrew in good order to the stronger Wangjiahe–Wulongguan line. On 26 November enemy strength grew to 4,000–5,000. One column advanced on Sanligang while the main body assaulted Peizhai, Wangjiahe, and Yunanmen. Fighting continued until dark without decisive result. On 27 November the main force of the 44th Corps counterattacked from Wangjiahe, converging with the 67th Corps advancing from the northwest. The coordinated assault inflicted severe casualties, yet the Japanese continued to fight stubbornly. On the Suixian front, more than 2,000 Japanese troops reached Liangshuikou on the morning of 25 November and launched a violent attack against the 123rd Division at Lishan. Two additional columns, each exceeding 1,000 men, pushed westward toward Hoyuantian and Qingmingpu; their numbers swelled steadily as darkness fell. On 26 November fierce combat raged against the 124th and 127th Divisions at Jinjishan and Qingmingpu. A separate force of 700–800 men advanced from Xihe via Langhetian to Tangjiafan. After clashing with the 41st Corps, the Japanese near Qingmingpu linked up with those at Jinjishan and moved toward Hoyuantian on 27 November. That night the detachment at Tangjiafan reached the vicinity of Huantan Zhen, confronting the 125th Division. Recognizing that the enemy had become dangerously dispersed, the War Area Command ordered its units to hold critical localities while the main forces exploited the mountainous terrain for ambushes. The tactic proved effective. Heavy fighting continued until 28 November, when the Japanese, unable to achieve their objectives, began a general withdrawal. Chinese forces west of Xiangyang immediately took up the pursuit. The enemy opposing the Right Army Group was routed and retreated along several routes. In the Suixian sector, Japanese units at Hoyuantian and Huantan Zhen were caught in converging attacks by the Central Army Group, driven back to high ground, and encircled. In a desperate attempt to relieve the trapped forces, the Japanese rushed 1,500–1,600 infantry and cavalry troops from Suixian and Yingshan through Shangshitian and Shatian in a flanking maneuver—only to be ambushed once more. Covered by aircraft and armor, the enemy withdrew toward Suixian and Xihe as Chinese troops pressed forward along the line from Chunchuan to Anchu, Lishan, and Gaocheng. By 30 November all Chinese Army Groups had restored their original positions. The Central Hubei Operation produced uneven battlefield outcomes, particularly in reported casualties. Japanese accounts describe relatively limited losses, just 132 killed and 445 wounded attributed to advantages in air superiority, artillery, and armored support, even though the advance was complicated by difficult terrain. At the same time, Japanese forces faced persistent Chinese counterattacks along the Han River, which contributed to localized pressure and eventual withdrawal. The Japanese reported 6,439 Chinese killed and 474 captured, but the evidence base is uncertain and the language of reporting suggests possible exaggeration or propaganda. Conversely, Chinese-era estimates reportedly placed Japanese losses at roughly 5,000 killed and 7,000–8,000 wounded, illustrating a substantial gap between competing narratives. Some alternate reconstructions suggest total Chinese casualties in the range of 20,000–30,000, depending on whether wounded and missing personnel are included. However, because wartime reporting was fragmented and inconsistent, there is no fully verifiable casualty ledger for all units involved. Despite these tolls, the operation did not appear to achieve a decisive Chinese destruction of Japan's intended target force. The Chinese Fifth War Area, including elements associated with the 31st Army Group under Tang Enbo, suffered attrition but generally avoided annihilation. No major command-level losses are indicated in the surviving accounts, and unit formations were not described as collapsing permanently. On the material side, Japan reportedly seized rifles and supplies from positions that Chinese forces had encircled or abandoned in the short term, but overall equipment losses for either side were described as limited, consistent with the operation's restricted intensity. Strategically, the operation offered Japan short-term tactical advantages—notably through localized envelopments and the temporary pressure of combined-arms support—but it failed to translate these gains into a sustained strategic result. The fighting also strained Japanese logistics in central China, especially given that the offensive was not followed by major reinforcements. At the same time, it exposed continuing vulnerabilities in rugged terrain where Chinese guerrilla activity and organized counteraction could offset superior firepower. Ultimately, the Central Hubei Operation produced no net territorial gains. By the end of the week, Japanese troops had returned to positions that did not fundamentally alter control in central Hubei. Local clashes may have disturbed formations and disrupted movement temporarily, but the campaign did not create durable forward bases, did not change administrative control meaningfully, and did not permanently disrupt key supply corridors. The territorial status quo largely persisted: Chinese Fifth War Area forces maintained positions north of the Yangtze River, and there was no widespread abandonment of strongholds sufficient to indicate a strategic collapse. In the months following the Japanese repulse in central Hubei in November 1940, enemy forces remained largely immobilized across the Jing-Xiang plains, their earlier ambitions checked by determined Chinese resistance. Seeking to regain momentum and draw Chinese strength away from other theaters, the Japanese high command prepared a massive offensive into southern Henan in late January 1941. By the end of the month they had concentrated an imposing array of seven infantry divisions, one independent cavalry brigade, three independent armored regiments, and one independent artillery regiment. In all, more than 150,000 infantrymen, over 8,000 cavalry, 550 artillery pieces, 300 tanks, and 200 armored cars stood ready. Over a hundred aircraft were massed at forward bases in Anyang, Xinxiang, Huaiyang, and Xinyang. From early January onward, ammunition and equipment had been laboriously shipped up the Yangtze and moved inland to Xinyang, while Japanese reconnaissance planes repeatedly overflew Chinese rear areas. Additional troops were concentrated in southern Henan itself. On 20 January, as a preliminary move to pin down Chinese forces and facilitate the main effort in central Henan, the Japanese 18th Independent Mixed Brigade, together with elements of the 39th and 4th Divisions, launched a limited attack against the Chinese 29th and 33rd Army Groups. The principal assault, however, began on 24 January under the overall command of Lieutenant General Katsuichiro Enbu. The Japanese organized their southern Henan forces into three powerful columns: The Left Flank Force, built around the entire 3rd Division reinforced by the 8th Regiment of the 4th Division and the Mizuno Armored Unit, commanded by Lieutenant General Fusataro Hanjima of the 3rd Division. The Central Force, centered on the 17th Division (less one regiment) and strengthened by the 67th Regiment of the 15th Division and the Yoshimatsu Armored Unit, commanded by Lieutenant General Amaya of the 40th Division. The Right Flank Force, formed around the main body of the 40th Division, also under Lieutenant General Amaya. In support of this main thrust, Japanese forces in northern Anhui and eastern Henan—principally the 4th Cavalry Brigade with the Hirabayashi Tank Regiment—advanced westward from Haozhou toward Woyang. The Ouda Regiment of the 21st Division pushed west from Suzhou, while the Uguchi and Kobayashi Regiments of the 35th Division, accompanied by engineer, cavalry, artillery, and tank units, moved from Kaifeng, Tongxu, and Zhuxian Zhen along the north bank of the Yellow River and through the flooded areas toward Zhengzhou. These supporting columns were intended to tie down Chinese reserves and prevent reinforcement of the southern front. The National Military Council in Chongqing correctly assessed the enemy's intention: to drive north along the Beiping-Hankou Railway with their main strength, force a decisive battle against the Chinese field armies, and rely on the northern Anhui–eastern Henan forces to strike westward in coordination. Accordingly, the Council instructed the Fifth War Area to avoid a costly frontal engagement. Instead, a small portion of its troops would offer delaying resistance along the railway, while the main force would maneuver to the enemy's flanks and rear, severing communications and launching devastating counterattacks. In compliance, the Fifth War Area left only a single division near Xiping on the Beiping-Hankou line. The bulk of its strength—carefully concealed in depth on both sides of the enemy's expected axis of advance—remained highly mobile, ready to strike the Japanese flanks or rear the moment the enemy divided his forces or pushed toward Runan, Yancheng, or Wuyang. This elastic strategy proved decisive. At dawn on 25 January the Japanese southern Henan forces advanced in three columns. The Left Flank Force moved along the line from Xiaolindian to Gucheng and Chashan. The Central Force struck northward from the Minggang area. The Right Flank Force crossed the Huai River between Huaijiao Zhen and Chengyang under heavy air support. Japanese planes bombed Chinese positions relentlessly. True to plan, Chinese units employed only light screening forces to harass the enemy with ambushes and flank attacks, preserving their main strength for the decisive moment. By 26 January the Japanese had reached the line from Piyang to Gaoyi, Xingtian, and Queshan. On the 27th they pressed on to Chunshui, Shahetian, and Zhumadian. At this point Chinese mobile forces sprang into action. The 13th Corps of the 31st Army Group swung northward toward Xiangheguan, while the main body of the 85th Corps moved toward Shangcai to begin an enveloping maneuver. The 68th Corps of the 11th Army Group struck the enemy rear south of Xiangheguan; the 55th Corps advanced from Tanghe to Piyang; and the 59th Corps of the 33rd Army Group pushed toward Nanyang. On 29 January the 13th Corps attacked the Japanese Left Flank Force near Jieguanting and Xiaoshidian south of Wuyang, while the 85th Corps struck the Right Flank Force around Runan, southeast of Shangcai. The enemy's Central Force, advancing along and west of the railway, found the Chinese positions already evacuated and failed to trap any major units. The Japanese columns on the extreme flanks suffered over 3,000 casualties and lost six tanks in the fighting around Jieguanting. By 31 January the enemy, desperate to rescue his exposed flank columns, reordered his forces. The Central Force executed turning movements on both sides: elements of the 15th Division swung right from Suiping through Shangcai to converge with troops moving north from Runan against the 85th Corps, while the main body of the 17th Division split into two columns and advanced from Suiping through Xiping toward Wuyang. Simultaneously, the main force of the 3rd Division and part of the 4th Division also converged on Wuyang, hoping to link with the 17th Division and crush the 13th Corps near Jieguanting and Xiaoshidian. Before the trap could close, however, the Chinese 13th and 85th Corps withdrew in good order to the area north of Ye Xian, between Yancheng and Shangshui, and north of the Sha River. When the Japanese broke through at Wuyang and Shangcai they found no major Chinese forces to destroy. Meanwhile, Chinese troops from western Henan, the 59th, 55th, and 68th Corps, advanced from Tanghe, Piyang, and points north to strike the enemy rear at Wuyang. On 29 January the 84th Corps and local guerrillas in western Anhui recaptured Chengyang and continued the pursuit. The Japanese, having failed to concentrate superior strength or control the battlefield, now found themselves isolated. Their rear communications were severed, and they were under constant pressure from the 68th, 55th, and 59th Corps. After days of exhausting combat the enemy began to withdraw southward on the night of 2 February. Leaving only rear guards at Wuyang and Baoanzhai to tie down the 13th Corps, the main body of the 3rd Division moved from Fangcheng toward Nanyang and Zhenping. The 13th Corps immediately counterattacked, recaptured Baoanzhai and Wuyang, and pursued the enemy toward Fangcheng. On the night of 2 February, as the Japanese main force approached Nanyang, the 17th Division together with elements of the 15th and 4th Divisions had already pushed south from Wuyang via Xiangheguan toward Piyang, hoping to link with forces moving east from Nanyang and trap the Chinese 68th, 55th, and 29th Corps. Fierce resistance by the 68th Corps near Xiangheguan inflicted heavy losses and forced the enemy to abandon large quantities of supplies. Further south, the 29th Corps exacted still greater casualties around Piyang. On the night of 7 February the trapped Japanese column split: part retreated along the Tanghe–Piyang highway, while the main body withdrew along the Tongbo–Xinyang highway toward Xinyang, leaving many dead behind. The Chinese 85th Corps pursued southeastward, while elements of the 13th, 29th, 55th, and 59th Corps harried the enemy toward Xinyang. By the time the fighting ended, all Chinese units had regained their original positions. In coordination with the southern Henan offensive, the Japanese forces in northern Anhui and eastern Henan advanced westward in four columns on the morning of 25 January. The Ouda Regiment of the 21st Division struck west from Suzhou. The 4th Cavalry Brigade, reinforced by the Hirabayashi Tank Regiment, split into three routes from Bozhou to attack Woyang, Shanheji, and Shuangqiao, clashing bitterly with a Chinese cavalry division near Shizihe and Niqiuji. The Uguchi Regiment of the 35th Division advanced through the flooded areas from Tongxu and Zhuxian Zhen, while the Kobayashi Regiment moved westward along the north bank of the Yellow River near Zhengzhou. Japanese aircraft intensified their bombing of Chinese cities and front-line positions, including Zhoujiakou, Zhengzhou, Yancheng, Ye Xian, Xiangcheng, Wuyang, and Luoyang. On 29 January one enemy column reached Santaiji and suffered heavy losses under Chinese attack. Threatened on the left by forces near Huaiyang, two Chinese corps withdrew temporarily to the line from Fuyang to Taihe and Jieshou. On 5 February the Japanese captured Taihe and Jieshou, but a Chinese counterattack on the morning of 6 February regained both towns, forcing the enemy to retreat northeastward. The Battle of Southern Henan, which opened on 25 January and concluded on 10 February after seventeen days of continuous fighting, ended in a clear Chinese victory. Japanese casualties exceeded 9,000; when the enemy withdrew from Nanyang more than 300 military vehicles were left burning on the battlefield. Large quantities of arms, ammunition, and supplies fell into Chinese hands. Chinese losses were significantly lighter. The enemy had hoped to force a decisive battle along the railway and shatter the Chinese armies of the Fifth War Area. Instead, skillful Chinese maneuver, timely flank attacks, and relentless pressure on the enemy's rear and communications had turned the Japanese offensive into a costly failure. The victory not only preserved the integrity of the central Chinese front but also demonstrated once again the effectiveness of elastic defense and mobile counteroffensive tactics against a numerically superior but overextended foe. In the wake of their costly repulse in central Hubei the previous November and the even more humiliating defeat in Southern Henan between late January and early February 1941, the Japanese sought once more to regain the initiative in the spring of 1941. Their target was western Hubei, where Chinese forces continued to deny them freedom of movement along the middle Yangtze. The entire Japanese 13th Division garrisoned the Yichang salient. Its regiments were deployed in a defensive arc: the 65th Regiment and the 19th Artillery Regiment held positions east of the city at Longchuanpu, Tumenya, and Yaqueling; the 104th Regiment guarded the northwest approaches; and the 17th Cavalry Regiment patrolled the Yangchalu–Baishanao sector. On the west bank of the Yangtze, the 58th Regiment had constructed strong bridgehead fortifications between Chaojialing and Shangwulongkou, ready to support any renewed thrust westward. Facing this entrenched enemy was the Chinese 26th Corps, entrusted with the critical mission of river defense on the west bank of the Yangtze opposite Yichang. The corps commander had organized his forces into three sectors. The 41st Division held the right zone, anchoring its line from Mujiatian and Tanjiataizi northward to the vicinity of Fanjiah u. The 32nd Division defended the left zone, stretching from Mujiatian through Ceyang to Xiangzikou. The 44th Division remained in corps reserve near Caojiafan, poised to reinforce either flank or exploit opportunities for counterattack. On 6 March 1941 the Japanese struck. Having quietly reinforced their forces west of Yichang to more than three regiments, supported by cavalry and artillery, they opened the assault at 5:30 a.m. with a violent artillery barrage, followed immediately by infantry advances under cover of air strikes. Chinese security positions at Tanjiataizi and Chaojiadian were overrun. The enemy then hurled itself against the main line at Changgangling. Simultaneously, 600 to 700 Japanese troops, backed by planes and guns, assaulted Fanjiah u. After hours of bitter fighting both localities fell. On the morning of 7 March, Japanese aircraft again spearheaded the attack, enabling the capture of positions at Qianjiatai and Wujiaba. The enemy pressed on toward Qianjiachong and Yutaishan but was thrown back. Meanwhile, the force that had taken Fanjiah u clashed fiercely with the Chinese 44th Division around Taipingqiao; although the division was eventually compelled to withdraw to the eastern end of the bridge under relentless air attack, it continued to resist stubbornly. When the enemy seized Hut zeye from the direction of Fanjiah u, the 32nd Division fell back in good order to the line from Tunziqiao to Tuyanzhong, where it beat off further assaults. By this stage the Japanese had driven themselves into a dangerously narrow salient, exposed on both flanks. Seizing the moment, the River Defense Force reorganized its lines. The 103rd Division of the 8th Corps relieved the sector from Mujiatang through Yingzishan to Chaotianguan, while the 26th Corps consolidated new positions at Yutaishan, Pijiashan, Qingshuiba, Guangongling, and Xiaopingshanba. The plan was clear: hold the enemy east of this line, then launch a converging counterstroke to destroy the invaders and restore the original front. On 8 March two guerrilla columns from the 41st Division struck at Changgangling and Fanjiayuan, while another detachment hit the enemy east of Pifengjian. More than 2,000 Japanese troops assaulted the 44th Division's positions from Gaolingpo and Dajiaobian toward Wanghuzizhong; determined resistance by the 44th Division, supported by elements of the 41st, brought the attack to a standstill. Later that day the enemy managed to penetrate the 32nd Division's line at Tianwangshi, forcing Chinese troops to fight a delaying action along the outskirts of the Shibai Fortress from Mingjiachong to Heitangou. Dawn on 9 March brought renewed Chinese initiative. The 103rd Division occupied the line from Tutiling to Shizinao and advanced in several columns against the enemy. A portion of the 44th Division waged a grim holding action on the high ground flanking Guojiaba, suffering heavy losses but buying time for the main body to launch a powerful flank attack against the Japanese at Taipingqiao and Xianglingkou. By dusk Chinese forces had captured the enemy strongpoints at Dujiaoba and Dajiaobian along the highway, annihilating numerous enemy troops. The 32nd Division threw its main strength against the area northwest of Dajiaobian; heavy fighting raged around Wanghuzizhong into the afternoon until enemy reinforcements were driven off. The 41st Division, meanwhile, executed effective flank attacks that yielded significant gains. On 10 March the 103rd Division recaptured the high ground at Xiawulongkou and north of Tianzipo, while guerrillas of the 41st Division continued to harass the enemy through every gap in his lines. When positions at Hongshipo and Lungtanping held by the 44th Division were breached, the division withdrew to the western heights of Bomuping and faced the enemy anew. At dawn on 11 March, after suffering severe casualties, the Japanese resorted to smoke screens and began withdrawing eastward along several routes. Chinese pursuit forces swiftly retook Xianglingkou, Guojiaba, Guangongling, Tianwangshi, and Dajiaobian. By 12 March the enemy had fallen back to a defensive line running from east of Taipingqiao to Hu z'ai and Huangnikeng. On 13 March Chinese units launched general counterattacks. Unable to withstand the pressure, the Japanese retreated to their original positions. The eight-day engagement thus ended exactly where it had begun. The battle had been fought with only a portion of the available Chinese forces, yet it proved decisive. The Japanese, who had hoped to crack the river defenses and resume their westward drive, instead suffered 4,000 to 5,000 casualties. The swift and skillful Chinese counteroffensive not only restored the front but left the enemy shaken and apprehensive. Their design to push deeper into western Hubei was decisively thwarted, buying precious time for the broader Chinese war effort in the Yangtze theater and demonstrating once again that determined defense, timely reinforcement, and aggressive counteraction could blunt even the most carefully prepared Japanese offensive.

In November 1940, a Central Hubei Operation using five task forces attempted to exploit Chinese dispersal but achieved no territorial gains despite local successes. A larger January 1941 offensive into southern Henan deployed 150,000+ troops but again failed strategically. Despite Japanese tactical advantages and superior firepower, logistical constraints and rugged terrain favored mobile Chinese resistance. Both campaigns ended with Japanese withdrawals and restored Chinese positions, demonstrating that determined defense and timely counteraction could blunt large-scale Japanese operations.

3.204 Fall and Rise of China: One Hundred Regiment Offensive #3

Last time we spoke about the second phase of the One Hundred Regiment Offensive. During the second phase of the Hundred Regiments offensive, CCP forces emphasized strongpoint and transportation warfare across the Taihang/Jizhong area. Units were organized with wings containing Japanese positions while a central force struck deeper, as in the Renhe Dasu fighting in early October 1940. Night raids seized strongholds, while engineers and sabotage teams disrupted roads, bridges, and mobility, and ambushes targeted Japanese foraging and supply routes. Across these theaters, the strategy was consistent: make Japanese control porous by destroying or capturing local nodes and forcing constant repairs, re-routing, escorts, and slowed reinforcement, so occupation logistics and strongpoint networks could not function reliably. This approach supported wider offensives by isolating strongpoints, draining enemy strength, and giving Communist base areas room to endure and expand. #204 The One Hundred Regiment Offensive Phase Three Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel where I cover the history of China and Japan from the 19th century until the end of the Pacific War. After the two large-scale offensives carried out over wide areas of North China, the Japanese army did what it always did when control started to slip: it tried to turn mobile pressure back into something it could "manage" again. The Eighth Route Army's continued fighting had shown that Japanese-occupied space was not secure, and that base areas could still resist, strike, and persist even while under counterpressure. That was dangerous for occupation. If the enemy could keep operations going, Japanese lines of movement stayed uncertain and "stabilization" became a temporary illusion. To prevent the situation from worsening and to re-stabilize the occupied areas as quickly as possible, the Japanese mobilized heavy forces and launched retaliatory counter–"mopping-up" operations against anti-Japanese base areas in North China beginning October 6. The Japanese attempt wasn't only to punish; it was designed to take advantage of an asymmetry: the Eighth Route Army was striking and fighting continuously, and it did not have the luxury of resting, replenishing, and re-cohering as neatly as a garrison army might. Japanese commanders hoped that if they struck hard enough in enough places, the Communist main forces could be isolated, destroyed, or at least forced into a defensive posture that would break their operational tempo. At Liaodong and Yulin, Japanese reinforcements also created a second political-military stake. After the Yuliao Campaign ended, the Eighth Route Army headquarters issued instructions on October 1 to major regions, warning that enemy reinforcements in Liaodong and Yulin might use the opening to "sweep" the Taibei region. In the Communist operational mind, this wasn't just one threat; it was a pattern. A "sweep" could come as a wave that pushed inward, burned villages, destroyed supplies, and tried to force Communist forces out of their protected networks. Even if the offensive couldn't win a conventional decisive battle, it could aim to strip the base areas of people, food, and mobility—things that make guerrilla and strongpoint warfare possible. By October 19, 1940, the Eighth Route Army headquarters issued a counter–"mopping-up" operation plan, and civilian and military authorities in various regions launched counter-"mopping-up" operations accordingly. This is important background: in these campaigns, "mopping-up" was not only an army activity. The Japanese were attempting to break the base system itself—its logistics, its local administration, and the relationship between armed units and civilians who hid, moved, fed, and replaced them. So the counter-operations had to be just as systemic. The Communists needed to keep people alive, keep movement possible, and keep the enemy from consolidating inside a cleared space. In southeastern Shanxi's Taihang and Taiyue regions, the Japanese 1st Army aimed to strike the main force of the 129th Division and destroy anti-Japanese base areas by running a series of mopping operations from October 6 to December 5. The plan had a typical occupation logic: push through strongholds gradually, clear pockets methodically, and rely on local superiority—especially in manpower, logistics, and the ability to reinforce by road. And because the Communist main force had been operating without meaningful rest after the earlier offensives, the Japanese believed they could catch formations while they were still "in between battles." On October 6, in the Taihang region, more than 800 enemy troops from Wu'an in western Hebei began a "mopping-up" operation in the Yangyi area. By October 11, the Japanese posture escalated. Part of the Japanese Independent Mixed 4th Brigade departed from Liaoxian and Wuxiang, while part of the 36th Division departed from Lucheng and Xiangyuan; together they totaled over 3,000 troops. Coordinating from north and south, they carried out operations to "mop up" both banks of the Zhuozhang River between Yulin, Liaoxian, and Wuxiang, encircling and clearing the south side of the Yulin–Liaoxian highway. This emphasis on riverbanks and highway corridors reveals the Japanese method: move along terrain that controls movement, then compress enemy options until the defenders have to fight inside a narrowing space. The counter to that method required more than bravery. The Eighth Route Army's 385th and 386th Brigades, along with the 1st Column of the Decisive Battle, fought on inner lines—where they could move more rapidly between known local positions and threaten the enemy's flanks or supply behavior. Meanwhile the New 10th Brigade fought on outer lines, where it could intercept, delay, and force the enemy to spend time reacting instead of clearing. By the morning of October 15, the New 10th Brigade delivered a concrete example of that interception strategy. Two regiments ambushed an enemy motor-transport convoy at Gongjiagou on the Heliao Highway, destroying more than 40 vehicles and annihilating more than 100 Japanese soldiers escorting the convoy. The meaning of a convoy ambush is strategic even when the numbers are modest: vehicles represent speed, logistics, and reinforcement. If the enemy loses vehicles repeatedly, "mopping" becomes slower, and slower clearing creates openings for the defenders to reorganize, disperse, or shift main effort. After that, on October 17, the enemy forces that had been mopping up the convoy withdrew in different directions. Withdrawal in multiple directions is a sign that the Japanese clearing operation, meant to compress a space, had instead been forced into a reactive mode. It also hints at a recurring pattern in these years: Japanese units could clear what was already weak, but when defenders hit their movement corridors, the occupiers had to spend time and combat power simply to recover mobility. The next major sweep began October 20, 1940, and it was much larger. Nearly 10,000 troops—from the 36th Division and Independent Mixed Brigade No. 4—set off from multiple locations, including Wu'an, Liaoxian, Wuxiang, and Lucheng, to sweep the area east and west of the Qingzhang River, focusing on land between Matian and Zuohui. Crucially, that was not random ground. The Japanese sought to strike the CCP Central Committee Northern Bureau, the Eighth Route Army headquarters, and the 129th Division headquarters, along with party and government organs of the Jin-Ji-Yu Border Region, located together with Shexian and Piancheng. In other words, the Japanese targeted not just armed units but the political-administrative heart that makes base areas function. Once in the attack area, the Japanese carried out "mopping-up" operations paired with burning and killing for several days. That brutality wasn't only cruelty; it served a purpose. Burning villages, destroying crops, and killing civilians could deny the base area food and shelter while making local cooperation more difficult. Then, on October 26, the Japanese began to withdraw and carried out mopping-up in different areas on the way back. The base area was "severely damaged and destroyed," indicating that even when the Japanese didn't annihilate the main Communist force, they could still achieve degradation—hurting the system they needed to keep operating. But the Communists were not simply absorbing damage. On October 29, a force of over 500 men from the 36th Division, plus over 400 supply and laborers, was mopping up Huangyandong and advanced through Zuohui to Guanjia'nao east of Panlong, preparing to return to Wuxiang. This is where counter-mopping becomes operationally dangerous for the occupier. Supply and labor detachments move differently from combat formations, and they represent an enemy's assumption that the base area is being "cleared." The Eighth Route Army headquarters ordered, at 1:00 p.m., for the 129th Division to concentrate its main force to annihilate the enemy. That night, the 129th Division—uniting the main forces of the 385th and 386th Brigades, parts of the New 10th Brigade, and the First Column of the Death Squad—surrounded the enemy at Guanjia'nao with a plan to launch a general offensive at 4:00 a.m. The besieged enemy, besides quickly building fortifications, seized Fengkengding high ground southwest of Guanjia'nao under cover of darkness. The two high points helped defenders support one another and resist stubbornly. The battle lasted until dawn on October 31, when most of the enemy had been annihilated, leaving only more than 60 men to hold positions. Then reinforcements arrived—over 1,500 from Huangyandong—supported by more than 10 aircraft. The 129th Division withdrew, and the remaining enemy fled toward the flood, leaving behind more than 280 corpses. By then, most Japanese troops had withdrawn from the central base area. The background stake is clear: "mopping-up" could damage and burn, but if defenders could convert the Japanese attempt into a trap—especially when enemy units had become separated from their core and committed to clearing—they could turn a destructive operation into a costly one for the occupier. In early November, the Japanese continued. In Licheng south of Taihang, Japanese forces invaded Nanweiquan and Beiweiquan and then Xijing. Elsewhere, Japanese forces in Xiangyuan invaded Panlong via Xiying, attempting to attack Dongtian and the area around Zhuanbi, where the Eighth Route Army headquarters was located. In that moment, the 386th Brigade was ordered to rush to the north–south line of Damocun, east of Panlong, block the invading enemy, and cover the transfer of the Eighth Route Army headquarters. At 9:00 a.m. on November 3, 1940, fierce fighting broke out as the troops finished deploying near Damocun. The Japanese launched continuous attacks and captured some positions. The 386th Brigade held until 4:00 a.m. on November 4, then withdrew after the headquarters successfully moved. The Japanese attempt to launch a pincer attack failed, and they retreated to the Baijin Line on November 5. Even when Japanese action couldn't be fully blocked, the counter's aim was not only tactical survival but prevention of strategic encirclement—protecting the central institutions and preserving the ability to fight again. In the northern Taihang region, more than 2,500 enemy troops from Heshun arrived in Yushe on November 3 via Hanwang Town and Changcheng Town, reinforcing Japanese forces in the Yu, Liao, and Wu areas. Then they carried out repeated mopping operations south of the Yuliao Highway, including Jiangtang, Lingshang, Songjiazhuang, Guojiao, and Dayouyi. Harassment and attacks by military and civilians forced Japanese troops back into their strongholds by the 13th. A "40-day" counter-mopping operation in Taihang came to an end. The term "40-day" isn't only calendar time; it suggests that these were not one-off battles but sustained campaigns of movement, dispersal, and repeated harassment meant to drain the enemy's capacity. Starting November 17, the Japanese launched a multi-pronged attack on Qinyuan and the area north of Guodao Town. The attack involved part of the 37th Division from Qin County and Nanguan Town, part of the Independent Mixed Brigade from Pingyao, Jiexiu, and Huo County, and a battalion of the 41st Division from Hongdong—more than 7,000 troops deployed to attack Qinyuan and the north area. But the Taiyue Military Region response shows how the Communist counter-mopping wasn't always to meet force with force. To avoid the enemy's "sharp edge," the Taiyue Military Region formed two detachments—Qin East and Qin West—with leadership and main force moving to both sides of the Qin River outside the Japanese attack zone, targeting scattered Japanese troops instead of being fixed into a single killing field. By November 23, due to harassment by local armed forces, the Japanese reached the attack zone and then carried out dispersed mopping operations. Qinyuan County was the most severely damaged, with more than 5,000 people killed (about one-tenth of its population), nearly 10,000 livestock killed and over 7,000 stolen, and 30,000 to 40,000 houses destroyed. Those details are brutal, but they explain why background stakes mattered: "mopping-up" was meant to break the social base. If civilians died or fled, the guerrilla system became harder to sustain. The response from the Dayue Military Region seized the opportunity created by Japanese dispersal. On November 23, the 42nd Regiment of the Qinxi Detachment annihilated more than 100 Japanese soldiers in Guantan. On November 27, parts of the 42nd and 59th Regiments killed or wounded more than 160 in Huhanping and Mabei. The Qindong Detachment's 17th and 57th Regiments inflicted serious damage in a series of places—Guang'ao, Chenjiagou, Longfosi, Wuyuanzhen, Nanweicun, Nanli, and more. The 17th Regiment's battle at Longfosi annihilated more than 100 Japanese. Additional heavy losses were inflicted by the 212th Brigade in Jiaokou. By December 5, the Japanese were forced to withdraw from the Taiyue area in separate routes. Strategically, dispersal punished the occupier because scattered units are harder to protect and easier to ambush. Across the Jin-Cha-Ji Border Region, anti-"mopping-up" operations unfolded gradually, beginning with the Pingxi area, the first target of the Japanese on the path toward the Japanese-held headquarters and rail lines. Pingxi mattered because it directly threatened the headquarters of the Japanese North China Area Army and Beiping—the puppet regime's center—and also threatened the Pinghan and Pingsui railways, North China's main transportation lines. So Pingxi became an operational priority: if the occupier couldn't keep the rail network secure, their ability to reinforce and supply their own strongpoints suffered. On October 13, 1940, more than 10,000 Japanese and puppet troops attacked Sanpo, the central area of the Pingxi base area, in 10 routes. This attack used a methodical, steady approach: advance gradually, rely on strongholds, and cover 5 to 10 kilometers each day. In response, the Pingxi Military Sub-district countered using timely maneuvers of its main forces and extensive guerrilla warfare. Over more than a week of fighting, the enemy was constantly harassed and attacked, wearing them down. Although Japanese troops penetrated deep, they failed to identify the main force's movements. By November 21, when the encirclement tightened further, the Pingxi main force jumped out from the Sanpo area and moved southwest. Encountering the enemy at Pengtou, it then moved to the Yegu and Datai line east of Bancheng. After the Japanese entered the Sanpo area, they conducted widespread burning and killing and looted grain. Starting from the 23rd, the Japanese retreated in different routes. By the end of October, the main force had withdrawn from Pingxi, but more than 2,000 troops remained in the Pingxi anti-Japanese base area to build strongholds and roads. Strongholds were added in places like Changping and Wanping—14 strongholds alone—and villages such as Dongzhaitang and Dujiazhuang came under their control. The base area began to shrink and shrink. That shrinkage is the other background stake: even when guerrilla forces avoid annihilation, the occupier may still carve away space through fortification. On October 19, 1940, the Eighth Route Army headquarters instructed that enemy attacks in Pingxi and Taihang might turn around and attack the Beiyue area. The Jin-Cha-Ji Border Region needed to prepare quickly to crush these "mopping-up" operations, coordinating Party, government, military, and civilians and conducting in-depth combat mobilization. The main force should assemble in appropriate positions and prepare to annihilate one or two enemy forces decisively. The headquarters also instructed the 129th and 120th Divisions to cooperate actively. By November 9, 1940, the Japanese struck again in a massive sweep. The 110th Division, along with other units and more than 14,000 puppet troops, launched a "mopping-up" operation in the jurisdiction of the 1st Military Sub-district. The Japanese and puppet troops moved in coordinated lines: along the line of Yi County, Dalonghua, Wang'an Town, Laiyuan, and Chajianling from north to south, while those in Baoding and Mancheng moved east to west. The intent was to squeeze Communist sub-district forces into a narrow area for a decisive battle. On November 10, the Jin-Cha-Ji Military Region issued operational guidelines and deployments for countering "mopping-up" operations. By the 12th, in response to Japanese widespread burning and killing, it further instructed that without hindering mobility, the main force could disperse a portion of troops—no more than one-third—to strike resolutely at attempts to burn and kill. That instruction captures the balance commanders tried to strike: disperse too much and you lose power; disperse too little and you become trapped by the occupier's brutality. The Japanese then attempted to pressure multiple places. On November 9, more than 6,000 enemy troops from Laiyuan, Yixian, and Baoding attacked Guantou, Yinfang, Huangtuling, and Shenbei. On the 12th, their attack failed; they burned and killed people before retreating in different routes. At that time, the 1st Military Sub-district assembled the 1st and 25th Regiments to intercept them. One enemy force of more than 800 was intercepted on the 14th as it retreated from Wujiazhuang to Yuangang; some were killed or wounded. Even so, the enemy broke through under aircraft cover and retreated to Guantou. On the way, it was intercepted again by the 20th Regiment, suffering heavy casualties, and it fled back to Mancheng. Then on November 13, more than 2,700 Japanese and puppet troops attacked the 3rd Military Sub-district; on November 14, about 2,600 advanced from Dingxiang, Dongye, and Wutai toward Fuping and its southwest area in two routes. The Japanese attacked with east-west coordination, launching joint attacks on Taiyu north of Fuping. The Jin-Cha-Ji Military Region headquarters and the command organs of the 3rd and 5th military sub-districts, along with the 2nd, 3rd, and 6th regiments and other troops, transferred to the outer line before the enemy encirclement formed. On the 16th, the Japanese launched a joint attack again on Taiyu and Zhangjiayu, and the guerrillas who failed to transfer fought hard. Commander Wang Pu and Deputy Director of the Political Department Hao Yuming were killed, and troops suffered more than 100 casualties. On November 18, the enemy from Taiyu quickly occupied Hanping City. By the 21st, enemy forces from Daying via Shentangbao and Wuwangkou, and from Wutai via Taihuai, Shizui, Longquanguan, and Xiaguan, also gathered in Fuping City. After occupying Fuping, the Japanese launched repeated attacks "sweeping" areas under the jurisdiction of the 3rd Military Sub-district from both inward and outward strongholds, conducting brutal burning and killing and destruction. On the night of November 21, the 2nd Regiment dispatched more than 30 men to raid Dangcheng and attack Japanese barracks with grenades. The Japanese panicked and fired guns and cannons all night. On the 26th, four plainclothes officers infiltrated Baoding and attacked a theater where the Japanese army was holding a meeting, causing panic among the Japanese. The enemy that had invaded the base area withdrew in different routes on the 25th. By December 3, 1940, most Japanese troops had withdrawn from the Beiyue area, but more than 1,000 remained along lines including Fuping, Wangkuai, Dangcheng, and Quyang to continue building points and roads in an attempt to occupy the area long-term. To force the enemy back, eliminate occupied points, and completely crush Japanese and puppet "mopping-up," the Jin-Cha-Ji Military Region organized the Fuping–Wangkuai Campaign starting December 9, with the 2nd, 3rd, 4th, and 6th regiments participating. At 21:00 on December 14, the 6th Regiment attacked enemy forces in Dongzhuang. The 1st Battalion captured three fortified positions on the north mountain of Dongzhuang and rushed into the village, only for Japanese counterattacks to recapture fortified positions and kill or wound more than 170 Japanese during the counterfight. The 4th Regiment attacked the enemy in Fuping; the 2nd Regiment and guerrilla forces entered Dangcheng and Lingshan. On the 21st, more than 130 enemy soldiers escorting more than 100 pack animals carrying military supplies reached Wangkuai and were completely annihilated when they reached Wanglinkou. By December 26, an ambush in the Xuancun area of the Pinghan Railway destroyed 14 Japanese trains and their vehicles as well as three heavy artillery pieces. On the 27th, more than 1,200 enemy troops advancing from Dongzhuang in Fuping were attacked in Luoyu and Tumen, suffering more than 140 casualties. The remaining Japanese withdrew from Fuping, Dongzhuang, and Wangkuai starting New Year's Day 1941. By January 4, the 55-day anti-"mopping-up" campaign had basically ended, with the Jin-Cha-Ji Military Region killing and wounding more than 2,000 Japanese and puppet troops while suffering 1,382 casualties itself. These numbers and dates show why background and stakes matter: the counter-mopping effort wasn't short. It was sustained, operationally demanding, and required continued offensive action even while facing superior Japanese resources. The pressure didn't end there. From October 25 to early November, about 4,000 Japanese troops, including the 16th Independent Mixed Brigade, launched a mopping operation in the Miyu and Loufan areas of the 8th and 3rd military sub-districts in northwestern Shanxi, but they were attacked by local soldiers and civilians. In mid-December, Japanese forces transferred additional strength: parts of the 37th Division from southern Shanxi and the 41st Division from southeastern Shanxi, along with parts of the 3rd, 9th, and 16th Independent Mixed Brigades and the 26th Division from northwestern Shanxi—totaling more than 20,000 troops—to prepare for a full-scale mopping operation in northwestern Shanxi. After the second phase of the Hundred Regiments Offensive ended, the 120th Division anticipated retaliation and actively prepared for counter-mopping. On October 30, the division was ordered to establish the Jin-Northwest Military Region, and on November 7, the military region was established in Lijiawan, Xing County. The Jin-Northwest Military Region had direct military sub-districts and six military sub-districts: the 2nd, 3rd, 4th, 8th, and Yanbei. Then the occupier escalated. Starting December 14, 1940, the Japanese launched a full-scale mopping operation against the Jin-Northwest region. More than 5,000 enemy troops invaded the Mi-Yu Town area of the 8th Military Sub-district, more than 4,000 invaded Lin-Xian, and more than 6,000 attacked Xing-Xian and the area south of Bao-De from strongholds such as Lan-Xian and Qi-Lan. By December 23, Japanese forces had occupied all county towns, most market towns, and Yellow River crossings in the Jin-Northwest region except for Bao-De and He-Qu counties, and began to implement a systematic policy commonly described as the "Three Alls" policy. The "Three Alls" emphasis is the clearest expression of stakes turning lethal. Japanese troops and traitors disguised themselves as the Eighth Route Army to lure and kill masses. They sent out core detachments to attack and repeatedly sweep the area, seeking to annihilate party, government, and military leadership organs—focusing on destroying the rear organs and facilities that made Communist endurance possible. According to incomplete statistics, more than 5,000 people were brutally killed during these sweeps. In Xingxian County alone, 150,000 catties of grain were looted and burned; in the 4th Military Sub-district, more than 5,000 head of livestock were looted and killed; and more than 19,000 houses and cave dwellings were burned down. In the early stage of this anti-mopping campaign, the Jin-Sui Military Region mainly used a portion of its forces to cooperate with local troops and guerrillas in widespread guerrilla warfare. They harassed and contained the attacking enemy, disrupted enemy transportation, and covered the transfer of the masses. The main force avoided the enemy's sharp edge and moved to the outer line to seek opportunities to attack the Japanese army. This describes the classic guerrilla operational pattern: avoid being fixed into a single decisive trap, but create enough friction that enemy operations degrade into a struggle they can't sustain. repeated attacks and ambushes during the mopping period across Miyu Town and other areas—units striking repeatedly, destroying roads, cutting off enemy transportation, and attacking enemy strongholds north of Dawu. To thwart the Japanese army's plans to build roads and fortifications—plans that would make future sweeps easier—the Jin-Sui Military Region instructed, on December 27, all sub-districts to mobilize forces to disrupt Japanese road construction and fortification. The 358th Brigade attacked enemy road construction from Lanxian to Dashetou and from Puming to Chijianling; the Independent 1st Brigade sabotaged the Dawu–Linxian highway; and the 4th Column of the Death Squad sabotaged the Dawu–Fangshan highway. Part of the Independent 1st Brigade's 2nd Regiment organized over 2,000 civilians to sabotage the Dawu–Sanjiao highway twice, forcing the enemy in Linxian to detour through Fangshan to contact Lishi. The Lishi guerrillas led civilians in two sabotage attacks on the Lishi–Jundu highway, destroying over 30 "li" of road. Other units attacked strongholds along key highways and destroyed or disrupted the "maintenance committees" that surrounded newly built enemy strongholds. There were also direct raids—storming into Linxian County and capturing representatives of enemy maintenance organizations. Meanwhile, the Workers' and Patriots' Brigade carried out continuous sabotage on the Taifen Highway. As the enemy plans ran into persistent disruption, Japanese and puppet forces began to retreat in different routes starting January 2, 1941, and by January 24 they returned to their original strongholds. The Jin-Sui winter counter-mopping operation lasted 40 days, annihilated more than 2,500 enemy troops, destroyed 125 kilometers of roads and 23 bridges, and recovered all towns occupied by the enemy during the campaign. Here the stakes show through most clearly: the campaign was not merely about killing enemy troops. It was about preventing the occupier from building a durable, road-connected grid that would allow future sweeps to be faster, larger, and more decisive. At the wider campaign level, the Eighth Route Army also recorded its total effects from August 20 to December 5, covering roughly three and a half months. During that period, the Eighth Route Army fought 1,824 battles of varying sizes, killing or wounding 20,645 Japanese soldiers (including senior officers), killing or wounding 5,155 puppet troops, and capturing 281 Japanese soldiers and 18,407 puppet troops. 47 Japanese soldiers surrendered voluntarily, and 1,845 puppet troops defected, totaling 46,380 people. The Communists captured 5,942 guns and 53 artillery pieces, and destroyed extensive transportation infrastructure: 474 kilometers of railway, 1,502 kilometers of highway, 213 bridges, 37 railway stations, 11 tunnels, more than 217,000 rails, more than 1,549,000 sleepers, more than 109,000 telephone poles, and more than 424,000 kilograms of telephone wire. Five coal mines and 11 warehouses were destroyed. The narrative further adds that when including casualties of Japanese and puppet forces across related engagements—such as Fuwang and the anti–mopping operations in northwest Shanxi—the total number of casualties reached more than 50,880. Japanese statistics were also cited for damage assessment, noting destruction of track and bridges across key railways (Zhengtai, Tongpu, Pinghan), telegraph pole damage, power line cuts, and effects on coal production—such as the Jingxing New Mine being unable to produce coal for at least six months. These details underline a broader background stake: infrastructure damage was meant to weaken the occupier's ability to keep its occupation apparatus working, even after the direct battles ended. The price of that multi-month struggle was high for the Eighth Route Army as well. Over the three and a half months leading up to the Hundred Regiments Offensive, the Eighth Route Army suffered 17,000 casualties, and more than 20,000 were poisoned. During the Hundred Regiments Offensive itself, post-war statistics state that the 129th Division suffered 7,362 casualties and 450 missing persons, and the entire division suffered 7,812 casualties. When you connect these lines—offensive sabotage, counter-offensives, Japanese mopping-ups, and anti-mopping resistance—you see why this second wave of fighting mattered. It wasn't only about whether the Japanese could respond to the offensive. It was about whether both sides could sustain their operational logic: the Japanese trying to stabilize occupation through "mopping," and the Communists trying to preserve base systems through dispersal, harassment, and counter-moves that convert the occupier's clearing effort into something too costly to maintain. The background of the Hundred Regiments offensive, who authorized it, who planned it, and why, remains unclear. The Japanese response was so severe that, in retrospect, it appeared to some as if the offensive had been a mistake. Some leaders, especially Mao, may have wanted to disavow it. Indirect hints in Mao's writings in subsequent months and years suggest he may have viewed it critically or harbored misgivings from the start. It was not the kind of strategy Mao preferred. More than twenty years later, during the Cultural Revolution, Red Guards charged that Mao had not even known of the plan in advance because of Peng Dehuai's alleged duplicity, at the time, Peng was being denounced. While this seems unlikely, it may contain some substance. In his own defense against these charges, Peng stated that after the 8RA headquarters—located not in Yan'an but in Jin-Cha-Ji—planned the operation, it sent mobilization orders downward to each regional command and also notified the Central Military Affairs Commission headed by Mao. In the original plan, the action would begin in early September. But, Peng wrote, to prevent enemy discovery and to ensure simultaneous surprise assaults—thereby inflicting an even greater blow to the enemy and the puppets—they began about ten days earlier than scheduled, during the last week of August. "So we did not wait for approval from the Military Affairs Commission (this was wrong), but went right into combat earlier than planned." There is also the issue of the "spontaneous" participation of more than eighty regiments without authorization from the Eighth Route Army headquarters, and not from Yan'an as well. If Peng Dehuai's account is accepted (written in 1970, shortly before his death), then Mao and Party Central had no role in conceiving or planning the Hundred Regiments campaign. In that case, the "grand strategy" motivations for undertaking it largely vanish—except perhaps insofar as they were considered by Peng and his colleagues. One alleged motive was to counter any tendency toward capitulation by Chiang Kai-shek and the Chongqing regime: if the war heated up and the CCP threw itself into fighting, any accommodation between Chiang and Japan would look like cowardly surrender. A related consideration was the Communist leadership's sensitivity to the charge that they were simply exploiting the war to expand their influence—avoiding Japanese combat while letting KMT armies bear the real burden of fighting. The Nationalists gave major publicity to the accusation that CCP policy devoted 70 percent of effort to expansion, 20 percent to coping with the KMT, and only 10 percent to opposing Japan. A third suggested motive was to divert attention from the New Fourth Army's offensives against Nationalist forces in Central China, which were peaking around the same time. Peng Dehuai acknowledged the campaign was "too protracted," yet he defended its importance in maintaining the CCP's anti-Japanese image in the wake of anti-friction conflicts, in demonstrating the failure of the cage-and-silkworm policy, in returning at least twenty-six county seats to base control, and in keeping "wavering" elements in line. Even if these reasons mattered less than regional and tactical calculations in launching the campaign, they could always be used for propaganda afterward. Whatever misgivings Mao and Party Central may have had, the Party kept them to itself. Mao radioed congratulations to Peng after his victory, and in public statements the Hundred Regiments were turned into legend. Even if the Hundred Regiments campaign aimed to defeat Japanese pacification efforts, it did not succeed in a decisive way. Shocked and stung by the 8RA's action, the North China Area Army intensified its efforts to bring North China under tighter control. Under General Tada and then his successor, General Okamura Yasuji (July 1941–November 1944), the Japanese inflicted brutal, sustained violence against all North China bases. Between 1941 and 1944, about 150,000 Japanese troops were assigned full-time to pacification duty, supported by roughly 100,000 Chinese auxiliaries of widely varying description and effectiveness. The remainder of the NCAA (about 150,000–200,000 men) was assigned to other tasks such as garrisoning major cities and containing Nationalist forces. Communist regulars were estimated at around 250,000 within base areas and 40,000 in SKN. The Japanese and their Chinese auxiliaries invested even more heavily than before in constructing moats, ditches, palisades, and blockhouses. Japanese sources claimed that by 1942 their forces had built 11,860 kilometers of blockade line and 7,700 fortified posts, mostly in the Hebei plains and the foothills of the Taihang mountains. A massive trench ran for 500 kilometers along the western side of the Pinghan railway line, with a depopulated and constantly patrolled zone on either side. The 250 Japanese outposts established in southern Hebei by December 1940 were more than quadrupled by mid-1942. These became the key means of controlling plains areas; by the end of 1941, all Communist bases in such terrain had been reduced to guerrilla status. Many main force units—such as those under Liu Cheng'ao and Yang Xiufeng—were compelled to move westward into mountains to survive. What distinguished the new Tada–Okamura approach from earlier tactics was the much larger and more protracted search-and-destroy thrust into the core mountain-base areas. They also replaced selective repression with indiscriminate, generalized violence. These infamous "Three-All" mop-up campaigns meant: kill all, burn all, loot all. Unable to distinguish ordinary peasants from Communists, the Japanese waged war on everyone. After attempting to seal off major consolidated regions in the base areas, they sent in very large detachments to search for Communist forces, civilian cadres, and activists. They also tried to destroy base facilities and war material stockpiles; to disrupt agriculture by burning crops or interfering with planting and harvesting; and to seize grain stores. Entire villages were razed, and everything alive found there was killed. Unlike earlier mop-ups that swept through an area and then departed, these campaigns left troops in the targeted zones for extended periods, "combing" the area back and forth and building at least temporary strongpoints in more accessible parts of mountain bases. These mop-up operations took a heavy and painful toll on rural populations. No doubt the harsh tactics and atrocities frequently committed during these actions did cause many peasants, rich and poor alike, to harbor deep hatred of the Japanese and to commit more fully to the Communist side. But intra-party sources also portray cases in which repression worked even more effectively than earlier attempts to drive a wedge between party and peasantry. As one internal assessment put it: If we only stress concealment… we are bound to be divorced from the masses. The morale of the masses cannot be sustained for long either. On the other hand, if we only seek fleeting gratification in careless fighting, we may also invite still more cruel enemy suppression. That will also alienate the masses. Communist spokesmen acknowledged that, in North China base areas, the population under Party control fell from 44 million to 25 million, while the Eighth Route Army declined from 400,000 to 300,000. Local records present an even grimmer picture. By 1942, 90 percent of the plains bases had been reduced to guerrilla zones or outright enemy control. In the mountainous Taiyue district within the Jin-Cha-Lu-Yi base, one cadre admitted that "not a single county was kept intact and the government offices of all its twelve counties were exiled in Jin-yuan." All twenty-six county seats occupied following the Hundred Regiments fighting were lost.

Japan tried to regain control through retaliatory "mopping-up" operations starting in October 1940. In response, the Eighth Route Army and its commanders issued counter-measures: coordinate party, government, military, and civilians; keep mobility while dispersing forces when possible; and focus on annihilating incoming enemy units decisively. Counter-sweeps and anti-pacification actions continued through December, involving repeated ambushes and sabotage of roads, highways, and fortification efforts.

3.203 Fall and Rise of China: One Hundred Regiment Offensive #2

Last time we spoke about the first phase of the One Hundred Regiment Offensive. On 20 August 1940, forces launched the Zhengtai Campaign, part of the "Hundred Regiments Offensive," aiming to disrupt Japan's transport network and thus weaken its "cage-and-strongpoint" defense. Orders from the Eighth Route Army split tasks: the Jin-Cha-Ji Military Region attacked the eastern Zheng–Tai line, the 129th Division struck the western section , and the 120th Division hit the Tongpu Railway and the Fen–Li Highway. Success was to be judged by the damage inflicted on the Zheng–Tai line. Preparations were conducted under strict secrecy: reconnaissance teams mapped Japanese strongholds with help from villagers; communities stockpiled grain, ammunition, and tools, and trained for demolition, including heating and bending rails. At night, units infiltrated stations and villages, seized positions, and destroyed bridges, power lines, roads, and mines across multiple columns; rain slowed movement and shaped the fighting. By early September, the Zheng–Tai line and related transport routes were severed, isolating strongpoints and hindering reinforcement. #203 The One Hundred Regiment Offensive Phase Two Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

During the second phase, the Hundred Regiments Offensive stopped being a single burst of action and became a sustained attempt to keep the Japanese occupation system off-balance. More regiments entered the fighting until, by the scale of commitment on the map, 104 regiments were involved. This matters because it changes what the campaign was: not merely a set of raids, but an effort to broaden pressure so that the enemy could not concentrate everything in one place at one time. Years later, Peng Dehuai—the commander closely associated with the Hundred Regiments offensive—described how the entry of these units felt as "spontaneous." That word can sound mysterious, so it helps to interpret it in operational terms. "Spontaneous" here does not mean unplanned chaos; it means that once the offensive logic took hold—once units saw that Japanese movement and control were being disrupted—local commanders and regiments felt empowered to join the fight without always waiting for the Eighth Route Army headquarters to issue fresh, detailed instructions for each smaller step. In other words, the campaign became something like an expanding network: local success and shared strategic perception fed into more participation across regions. Strategically, the campaign was guided by political and military guidance issued on September 10, 1940 by the Central Committee of the Chinese Communist Party. That instruction tied current operations to the earlier political-military framework of the July 7 Declaration and the July 7 Decision. The instruction argued that the moment mattered: it called for focusing "main efforts" on striking the Japanese army during a period when unity was being strengthened. It specifically urged that, based on the experience of the North China Hundred Regiments Offensive, Communist forces should organize one or more planned large-scale offensive operations in Shandong and Central China. In North China, the instruction pushed for expansion into Japanese army areas that had not yet been attacked—because the battlefield effect of the campaign was not only measured in immediate battlefield outcomes, but in reducing enemy-occupied space, enlarging base areas, breaking through blockade lines, and improving combat effectiveness. That last phrase—"Striking the enemy and attacking our allies is the general policy of military operations at present"—was the harsh shorthand for the operational reality: the campaign had to prevent Japanese occupation from appearing stable and manageable. If the occupation system could treat insurgency as "localized trouble," it would recover quickly. If, instead, occupation became dangerous in multiple places at once—requiring constant defense, constant movement, constant reinforcement—then the Japanese would be forced into a defensive posture that undermined their ability to exploit control. On September 16, 1940, the headquarters issued the second phase plan with a clear aim: expand results from the first phase. The headquarters explained the second phase would continue with an emphasis on disrupting Japanese transportation and destroying some strongholds that had penetrated deep into the base areas. This reveals the campaign's real "background and stakes": the offensive wasn't built around capturing territory in the traditional sense alone. It was built around breaking the system that makes occupation work. In the enemy's logic, occupation relies on movement: soldiers need to move, supplies need to be shipped, and reinforcement must be routed quickly to where trouble appears. Transportation infrastructure—roads, railways, bridges, power lines—forms the skeleton of control. Strongholds and outposts are the organs that occupy space, but they depend on that skeleton. If transportation becomes unreliable, strongholds become isolated islands. If strongholds become isolated, the Japanese must decide between (1) defending each island and spreading themselves thin, or (2) leaving some islands to contain the rest—either way, control weakens. Strongpoints—whether forts, fortified villages, gatehouses, or road blocks—also function as a "cage-and-silkworm" system: they are placed so Japanese forces can consolidate inside them, while routes outside are controlled or denied. In that model, even a small disruption can trigger a major ripple effect. When highways or key segments of rail are repeatedly broken, Japanese units cannot move "cleanly." They must detour, slow down, repair under threat, or escort repairs with larger forces than they prefer. Every extra hour spent repairing is an hour not spent consolidating. Every detour is a chance for ambush or for further sabotage. The second phase sought to exploit that dependency deliberately. That strategic framing explains why, even as the campaign broadened, different regions emphasized different battles. The Jin-Cha-Ji Military Region mainly fought the Lai-Ling Campaign, the 129th Division mainly fought the Yu-Liao Campaign, and the 120th Division focused on attacking the Tong-Pu Railway. They were not separate stories. They were different methods of attacking the same underlying vulnerability: the occupier's ability to move, reinforce, and coordinate. In Jin-Cha-Ji's sector, the stakes were especially sharp around Laiyuan and Lingqiu. The Japanese forces stationed in Mongolia had occupied those areas and penetrated deeply into the northwestern parts of the Jin-Cha-Ji Border Region. Japanese strength around these positions included elements of the 2nd Independent Mixed Brigade and the 26th Division, totaling more than 1,500 men, plus more than 1,000 puppet troops. The presence of puppet forces mattered not only for manpower, but because puppet troops supported the occupier's local control apparatus: they served as locally sourced enforcers, scouts, guards, and "administration-adjacent" security. Removing or weakening them was part of disrupting occupation credibility and local stability. Because the Japanese had been attacked in the first phase, they did not respond by retreating into passivity. They increased troops at each stronghold. Laiyuan City alone was reinforced to around 500 men, and the Japanese strengthened fortifications and stockpiled food and ammunition. This meant the defenders were preparing for a second round: not a sudden surprise raid, but a sustained threat that would test their ability to endure isolation and keep their network intact. Under these conditions, the Jin-Cha-Ji leadership decided to mobilize forces for the Lai-Ling Campaign, beginning at 22:00 on September 22, 1940. Here the background and stakes show up in the campaign's timing and tactics. The objective was not to "beat the defenders in open battle" only; it was to attack in ways that would prevent consolidation. By pushing on county areas and surrounding strongholds immediately, the attackers aimed to force the defenders into reactive mode—closing gates, shifting forces into defensive positions, and preparing for fights that would consume time and ammunition. The right wing launched a fierce attack on Laiyuan County and surrounding strongholds. After a night of hard fighting, the east, west, and south gates were taken, and the Japanese troops retreated into the city. Taking gates matters because it compresses space. It turns a wider defensive perimeter into a narrower, more concentrated posture. It also creates a psychological and operational trap: defenders who retreat into the city may survive longer as a fortified concentration, but their ability to conduct aggressive movement outside their walls—and their ability to receive reinforcements through many approaches—becomes more limited. In the night of September 23, the 2nd Regiment, supported by a battalion of the 1st Regiment and artillery, attacked Sanjia Village, described as an important enemy stronghold on the Laiyuan–Yixian highway, roughly 10 kilometers east of Laiyuan City. Highways are not just routes; they are corridors that connect strongholds to each other and to supply lines. By capturing a stronghold on a highway, the campaign attempted to break a portion of the corridor network feeding the city. The attackers annihilated most of the enemy and captured the village. At the same time, the 3rd Regiment attacked Dongtuanbao, northeast of Laiyuan City, and by the night of September 24, they had taken surrounding fortifications and forced remaining enemies into only a few houses inside the village. Then, on September 25, the enemy burned weapons, supplies, and food stored at the stronghold, preparing for a breakout. That detail reveals a key stake of stronghold warfare: if defenders believe they cannot hold and cannot escape, they may destroy supplies rather than let attackers seize them intact. It's a grim tactical psychology—destroying stores can deny the enemy immediate benefit, even if it reduces defenders' chances of future endurance. When the attackers launched another fierce assault and the remaining defenders, with no hope of escape, threw themselves into the flames and perished, the event underscored the "closed-options" nature of the battle: the stronghold system was being compressed until breakout became impossible. On September 26, other right-wing units, together with the 9th Regiment of the Pingxi Military Sub-district, captured 13 strongholds including Taohuabao, Bailebao, Jijiazhuang, Xinzhuang, Beikou, Xiabeitou, Baishikou, Zhongzhuang, Wangxidong, Liujiazui, Zhangjiayu, Beishifo, and Jinjiajing. Capturing strongholds in clusters has a strategic function. It doesn't just remove personnel; it interrupts local control geography. It makes it harder for defenders inside the city to extend influence outward and harder for them to create new safe points for movement. But the Japanese did what well-prepared occupiers can do: reinforce at the most important time and the most important place. On the second day after the start, Japanese reinforcement began from Zhangjiakou and other locations. Roads had not been completely destroyed, so the Japanese could advance rapidly. This becomes a major background lesson of the second phase. The first phase had demonstrated the power of sabotage to disrupt Japanese movement. But by the time second-phase campaigns began, the Japanese were not ignorant—they were learning. Where sabotage had fully severed roads, reinforcement could be delayed or routed into danger. Where sabotage remained incomplete, reinforcement could arrive quickly, changing the battle's character from attack-dominant to defense-dominant. By noon on September 28, over 3,000 Japanese and puppet troops arrived in Laiyuan City by car, supported by 20 tanks and 4 aircraft. This mechanized support was not just "extra firepower." It was a statement about how the Japanese aimed to retain control: tanks and aircraft increase defenders' ability to resist assault and keep morale from collapsing. Under these conditions, the right wing found it difficult to launch a favorable offensive. So the Jin-Cha-Ji leadership shifted offensive focus to the Lingqiu area, rather than forcing the original plan to continue against reinforced mechanized defense. The first step was to eliminate enemy strongholds between Lingqiu and Hunyuan. The second step was to seize enemy strongholds along a line from southeast of Daying to Shentangbao, and in mountainous areas north of Daying and Shahe. This shift highlights a core strategic principle: when a target becomes too fortified, the offensive can still succeed by moving the pressure elsewhere—aiming to break the enemy's network of strongpoints and keep forcing them to respond across space. On October 2, the headquarters ordered the main force of the right wing to concentrate in the area east and southeast of Laiyuan. Part of the force was assigned to monitor and contain the enemy in Laiyuan, while the 1st and 2nd Regiments were placed under the left wing's command and joined the left wing in combat. This reallocation reflects operational adaptability. If a city becomes a fortress, smaller units may be better employed as containment—tying down defenders—while the main effort moves to seize other stronghold lines where the Japanese might still be vulnerable. The fighting continued with tactical attacks that show how strongpoint warfare unfolded in the field. On the night of October 8, the 1st Battalion of the 1st Regiment launched an attack on the 2nd Regiment while a portion of the Japanese army in Nanpotou was attacking it. The attackers broke into enemy lines, annihilated most of the enemy, and drove the rest off. At the same time, the 1st Battalion of the 6th Regiment captured Qiangfengling, and the Japanese forces in Qingciyao fled in panic. The campaign also included actions such as attacks on Jinfengdian by the 3rd Battalion of the 6th Regiment on the night of September 9, and mention that the 26th Regiment entered Huangtai Temple on the night of October 8 while attacking between Lingqiu and Guangling. By understanding the background and stakes, you can see what these actions were really doing. They weren't random. They were repeated attempts to keep dismantling the enemy's ability to maintain a functioning strongpoint chain. Each captured stronghold reduces the enemy's ability to create secure corridors. Each panic-driven retreat increases their time burden and may cause breakdown in communication between local nodes. Even when the battle remains fierce and deadly, these changes in tempo can accumulate into operational outcomes. The Lai-Ling Campaign lasted 18 days, producing concrete results: killing and wounding over 1,000 Japanese and puppet troops, capturing 49 Japanese and 237 puppet troops, and leaving 1,419 casualties for the Eighth Route Army. The losses show the campaign was not a "clean victory." It was expensive. But the operational logic—disrupting a strengthened occupation zone, capturing strongholds, and forcing enemy reinforcements to concentrate—was consistent with the second phase's broader mission. Support for Lai-Ling came from the Jizhong Military Region through the Renqiu–Hejian–Dacheng–Suning Campaign from October 1 to October 20, simultaneously sabotaging the Cangshi, Deshi, Beining, and Jinpu railways. This is where "background and stakes" become especially clear. The Japanese, even when they defend in one area, have to move elsewhere to respond. When you attack multiple transportation lines and strongpoint zones at once, you prevent the enemy from solving one problem cleanly before moving to the next. You make the enemy chase multiple fires. After the Hundred Regiments Offensive began, Japanese forces in Jizhong moved west to reinforce in some cases, but most were tied down on important transportation lines. That relative weakening meant defenses in Jizhong's interior became weaker—creating space where a larger contest could occur. Jizhong decided to deploy 10 battalions totaling more than 8,500 men from the 18th, 23rd, and 30th Regiments across left wing, center, and right wing roles, fighting in the area. The plan was not only to attack; it was to manipulate where the Japanese had to respond. The two wing units would contain and draw Japanese forces away from the central Renhe Dasu zone, and then the central unit would break into that central area to open the situation. In other words: wings would pull; center would punch. The Renhe Dasu battle began on October 1, 1940. On the left wing, the 18th Regiment entered an area east of the Zhulong River and west of Hejian and Renqiu, capturing Lianjiazhuang, Dongguxian, and Liangcun between October 2 and October 6. By the night of October 7, Japanese troops at strongholds including Yuhuangmiao, Fenglebao, and Liushansi fled in panic—another reminder that once stronghold cohesion fractures, the enemy's ability to endure a second phase of pressure drops. On the right wing, the 30th Regiment operated with four battalions east of Dacheng and east of the Ziya River, capturing a series of strongholds including Liminju, Dengzhuangzi, Shigeju, Xiliuzhuang, Zangzhuangzi, and Chencun, while engaging in road-breaking and ditch digging. These actions show the campaign's "method," not just its target. Even when the opponent could be fought directly, sabotage and engineering measures could amplify the damage by reducing mobility and forcing time-consuming repairs. The central unit, the 23rd Regiment, had two battalions crossing the Hutuo River northward. On October 1, it ambushed more than 100 Japanese troops coming from Shangjialin to seize grain, killing more than 90 and capturing all their weapons. On October 9, it ambushed the enemy from Liugezhuang to Litan at Baimatang, annihilating 20 Japanese and puppet troops. These ambushes illustrate a second background principle: occupiers need sustenance and extraction operations, and those operations follow routes and patterns. By striking troops during foraging or supply-related movement, the offensive attacks not only the army but also the logic that keeps occupation armies fed and maintained. From October 15 to October 20, the second stage of those operations targeted the east and west banks of the Ziya River, leaving only a small force in the central Renhe River Great Suppression area. On the night of October 19, the central force captured Banjiehe and destroyed a bridge over the nearby Guyang River. On the night of October 16, the left wing captured Daqudi and the Renqiu Shimen Bridge, and on October 18 it captured the stronghold at Wangpan. A note in the operational description also indicates that the right wing faced a serious enemy situation and could not take major action during one segment—another reminder that even a planned operation cannot control all battlefield variables. What matters is whether the operation still meets its strategic purpose, not whether every segment goes perfectly. In the Battle of Renhe Dasu, Japanese and puppet losses were heavy: 805 killed or wounded, and 3 Japanese and 326 puppet troops captured. The campaign took 29 strongholds. The Jizhong Military Region suffered 573 casualties. Strategically, this battle contained enemy forces and effectively supported the Battle of Lai-Ling. Again, support here is not just "help in the same region," but redistribution of pressure: by forcing the enemy to allocate troops to Jizhong, Japanese defenders around Lai-Ling face more difficulty maintaining overall operational coherence. While Jin-Cha-Ji and Jizhong fought around Laiyuan and Lingqiu, a deeper pressure developed in the Taihang base region—through the Yuliao (Yu-Liao) Campaign, fought mainly by the 129th Division. The background stakes in the Yu-Liao theater were the highway route from Yangquan through Pingding, Heshun, Liaoxian to Yushe, described as the deepest penetration route through which the Japanese penetrated the Taihang base area. The Japanese tried to extend this road southwestward and connect it with the Baijin Railway through Wuxiang, aiming to split the Dahang area and deploy forces flexibly along the Zhengtai and Baijin lines. This was about strategic mobility and operational geometry. A road connection isn't only "transport"; it reshapes where the enemy can exert pressure and how quickly they can shift forces from one axis to another. The Yuliao section measured 45 kilometers and included eight strongholds: Yushe, Yanbi, Wangjing, Guantou, Pushang, Xiaolingdi, Shixia, and Liaoxian. These were guarded by the 13th Battalion of the Japanese 4th Independent Mixed Brigade. A line of strongholds along a highway is the occupier's version of a corridor defense: it enables them to keep movement inside a protected chain. If that chain is cut, movement becomes vulnerable and the "deep penetration route" turns into a dangerous liability. On September 22, 1940, the 129th Division issued basic orders: launch a surprise attack to eliminate the enemy from Yushe to Xiaolingdi, recapture strongholds, destroy the highway, and then press forward toward Liaoxian to recapture it when the opportunity arose. This is a textbook example of how the offensive combined surprise, seizure, and destruction. Surprise prevents the defenders from organizing a coordinated response. Seizure eliminates their nodes. Highway destruction prevents them from restoring their corridor quickly, forcing time and labor—exactly what the second phase wanted. The assault began on the night of September 23. On September 24, the left wing captured Yanbi and Wangjing, while the right wing captured Pushang and Xiaolingdi. By September 25, Yushe and Jucheng had also fallen, leaving only the enemy at Guantou on the Xiaolingdi–Yushe line still resisting. Concurrently, detachments attacked on related axes: the Pingliao Detachment captured Hanwang Town north of Liaoxian; the Qinbei Detachment sabotaged roads and attacked frequently, pinning Japanese forces on the Wuxiang and Baijin routes. On September 26, the 129th Division ordered part of the right wing to continue besieging the enemy at Guantou, while the main force and the left wing moved east to recapture Liaoxian and eliminate reinforcements. At dawn on September 27, the right wing attacked Shixia west of Liaoxian and captured it that night. On September 28, the left wing reached near Majiu in preparation for an attack on Liaoxian that night. Then battlefield logic reasserted itself: the Japanese did not sit idle once their corridor was threatened. Troops from Heshun and Wuxiang reinforced Liaoxian and Guantou respectively. The Eighth Route Army headquarters ordered the Liaoxian attack halted. Some forces were to contain the enemy advancing south from Heshun, while the main force moved to the Hongyatou and Guandinao areas to prepare to annihilate enemy reinforcements arriving from Wuxiang. This decision reveals a deeper stake: even if an army can seize targets, it must avoid exhaustion and must avoid allowing the enemy to convert a partial tactical loss into a larger opportunity. Headquarters essentially chose the operation's "survival path": shift from capturing more nodes to annihilating the reinforcements that would otherwise restore the corridor. Following these orders, the 129th Division attacked Guantou and took it at 24:00 on September 29. In the narrative description that follows, the enemy reinforcements moving through ambush terrain clashed with Communist formations in an engagement where aircraft coverage and terrain allowed the enemy to seize high ground and resist stubbornly. The battle lasted two days and one night, with heavy casualties on both sides. That is an important background lesson: the offensive could still destroy corridor nodes, but the enemy's ability to bring aircraft support and seize terrain meant that the "destroy and move on" approach wasn't always enough. Sometimes, momentum had to be re-channeled into another kind of contest—one closer to a blocking ambush and a battle of endurance. By the evening of October 1, more than 500 Japanese troops from Liaoxian broke through the right wing's blockade and approached near the left wing's command post. The left wing was ordered to withdraw from the battle. Headquarters then assessed that Japanese troops from Liaoxian and Wuxiang had joined and that more than 1,000 Japanese troops from Yangquan had reached Hanwang Town north of Liaoxian. Combined with the 129th Division's exhaustion and heavy casualties, headquarters decided to end the Yulin–Liaoxian Campaign—not because the offensive had no value, but because the risk of allowing the enemy to "sweep" the Taibei area could outweigh further gains. This termination decision illustrates a stake that is often overlooked: in insurgency-style campaigns, operational survival is part of success. The second phase did not merely chase targets; it sought to transform conditions so that the enemy would have to spend strength defending a failing network. If continuing a battle risks letting the enemy regroup into a larger counter-offensive that clears base zones, then ending becomes strategic. While the 129th Division wrestled with corridor defense around Liaoxian and Guantou, the 120th Division pursued a transport-centered strategy against the Tong-Pu Railway—because rail disruption was not a supporting detail; it was a main axis of pressure. On September 12, 1940, the 120th Division issued an action plan for the northern section of the Tongpu Railway, deciding to attack the Ningwu and Xinxian sections (with emphasis on the section between Ningwu and Daniudian) starting September 20. This timing shows planning designed to synchronize with broader operational pressure. Rail sabotage required engineering preparation and coordination across units, and the campaign sought to create disruption when the enemy would be most vulnerable to delayed reinforcement. On September 14, the 358th Brigade left its base west of Loufan and crossed the Jingle–Lanxian Highway to the north. It assembled at Majiagou on the 16th, then launched an attack on Toumaying using its 3rd Detachment (comprising the 7th and 8th Regiments and the special service battalion). At 24:00 on September 18, that detachment attacked Touma Camp, while the 7th and 8th Regiments attacked reinforcements. Fighting continued until the following morning when more than 40 Japanese soldiers from Ninghuabao reinforced Touma Camp. Once reinforcements reached Shanzhai Village, they were surrounded and annihilated. On September 20, around 200 Japanese soldiers from Yangquanling went to Liyan Village to counterattack. The 716th Regiment attacked at 14:00, and by dawn the next day, the enemy fled back to Yangquanling. These battles are more than local clashes. They serve the background logic of sabotage campaigns: before destroying rail infrastructure, you need to reduce the enemy's ability to respond instantly. Fighting reinforcements and counterattacks clears windows of time. Those windows can then be used to sabotage tracks, bridges, and related installations. If sabotage occurs under active reinforcement pressure, the enemy can repair quickly or trap the sabotage teams. If sabotage occurs after the enemy's response capacity is disrupted, repair becomes slower and the operational effects last longer. Parallel operations reinforced this logic. On the night of September 16, the Independent 1st Brigade crossed the Fen River east. On September 18, it was learned that more than 400 Japanese troops had attacked the Yanbei Detachment at Yangquanling but returned to Shangzhuang after failing to find them. The brigade then chose to encircle and annihilate the enemy rather than chase endlessly. The attack began at 13:00 on September 18 and lasted until early morning on September 19. The main force withdrew to sabotage the railway, while the remaining enemy retreated to Yangquanling. The engagement inflicted 105 casualties on the Independent 1st Brigade, while killing or wounding about 200 Japanese. Once the blocking threat was removed, units quickly moved into sabotage actions on the Tongpu Railway. Then sabotage itself proceeded systematically. On the night of September 22, the 4th Regiment of the 358th Brigade—attached to the division's engineering company—and the division's special service regiment advanced to the area between Duanjialing and Xuangang to sabotage several sections of the Tongpu Railway. At the same time, the 2nd Regiment attacked Qicun, and the 715th Regiment attacked Xinkou and Loubanzhai. On the night of September 23, the 2nd Regiment sabotaged the railway south of Xinkou while the 715th Regiment sabotaged it north of Xinkou. On the night of September 25, the 715th Regiment sabotaged between Daniudian and Xuangang. The Independent 2nd Brigade also sabotaged several railway sections between Shuoxian and Ningwu. After six days of sabotage operations, the 120th Division again caused the Tongpu Railway to be interrupted. The background stakes here are straightforward but huge: a rail interruption forces the occupier into repair work, escorts, and re-routing. During the second phase—when the Japanese were already under pressure across multiple theaters—the need to continuously handle repair reduces the capacity for offensive operations and for rapid reinforcement to any single contested point. It also slows their ability to respond to new threats as quickly as they would like. By connecting all these threads—Laiyuan and Lingqiu strongholds, Renhe Dasu containment and roadbreaking, the Yuliao highway corridor fight, and repeated Tongpu railway sabotage—you can see the deeper logic of the second phase. The campaign aimed to create a battlefield environment where Japanese forces could not enjoy stable mobility and where strongpoints could not function as a reliable cage. Transportation disruption isolated strongholds. Stronghold destruction and capture shrank the enemy's local control points. Highway and rail sabotage forced the Japanese to defend not only troops and walls, but also the infrastructure that enabled their coordination. That's why the second phase emphasizes disrupting transportation and destroying some strongholds penetrated deep into base areas. It wasn't simply "hit more places." It was a deliberate attempt to force the Japanese to abandon their preferred operational pattern: a networked system of strongpoints supported by transportation reliability. If that reliability breaks down, the occupier's "cage" becomes porous and unstable, and Communist base areas gain room to expand and persist. By early October, the second phase was winding down, while a third phase was developing: reinforced Japanese columns sought to engage and destroy 8RA units. Over the next two months, several fierce counterattacks occurred, and after that the Hundred Regiments campaign was considered to be finished.

After earlier setbacks in the 1930s, the CCP sought national leadership in resistance while maintaining political room to maneuver within an uneasy arrangement with the KMT. By early 1940–1941, the strategy shifted toward "strongpoint" and transportation warfare: guerrilla actions were used to fracture Japanese defensive networks and sabotage logistics. Japanese attempts to consolidate territory, through local administration and security practices—often provoked the CCP's dual struggle, militarily and politically. As Japanese sweeps temporarily gave the CCP advantages, the situation forced rapid adaptation.

3.202 Fall and Rise of China: One Hundred Regiment Offensive

Last time we spoke about the New Fourth Army Incident. Across the Second Sino-Japanese War, the CCP entered after the setbacks of the 1930s, seeking to become a national leader in resistance while remaining cautious toward the Nationalist government. The 1936 Xi'an Incident reshaped politics, and by August 1937 KMT–CCP agreements defined a working arrangement: the CCP acknowledged KMT leadership and integrated its forces, while still pursuing political space and autonomy. As the war progressed, the CCP focused on defining its relationship with the KMT and keeping operational independence during cooperation. Mao Zedong managed this alliance by promoting a united front against Japan, yet protecting CCP revolutionary goals and internal control. The establishment of the Eighth Route Army and New Fourth Army marked this military reorganization. Throughout, the CCP feared that KMT collaboration with Japan could enable a peace settlement that would undermine communist legitimacy and restrict the party's future authority thereafter. #202 The One Hundred Regiment Offensive Phase One Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel where I cover the history of China and Japan from the 19th century until the end of the Pacific War. Simultaneously with the friction between the Kuomintang (KMT) and the Chinese Communist Party (CCP), the Japanese were also working to take control of—and extract value from—most of the territory they had nominally conquered. Treating these two processes separately—"friction" on the one hand and "consolidation" on the other—does violence to the real difficulty of the CCP's dilemma: the Party often had to confront both problems at the same time. At certain moments, the CCP was effectively forced to wage a two-front struggle. Even so, if the worst of the KMT–CCP friction had already eased by 1941, the most serious and painful challenges posed by Japanese consolidation were still ahead. To recover anything close to reality, the two timelines have to be read together and placed on top of one another. The Japanese understood that consolidation could not be postponed, because much of the land behind the furthest reaches of their army was still only weakly under their actual control. In some places, order could be restored by relatively direct methods: rebuilding local administration and policy authority; repairing transportation and communications; enrolling Chinese personnel—usually, as it turned out, people of dubious reliability—as police or militia under puppet regimes; registering the local population; and requiring identity cards. In true old-style Chinese fashion, collective security practices were used widely. One form was the familiar bao-jia system, in one variant or another. Another was the so-called "railway-cherishing village": a village would be assigned a nearby stretch of track, and if residents failed to "cherish" it, they were held collectively responsible. Yet early Japanese weakness in northern China is vividly illustrated by an incident in the summer of 1938. Three young foreigners—vacationing from teaching in Peiping (Beijing)—were curious about events and about what people were doing. They loaded their bicycles on a southbound train, got off at Baoding, and rode west until they ran into Eighth Route Army detachments. In the early period of the war, commanders generally wanted to rely on more mobile forms of warfare. Mao, however, insisted on a strategy of de-escalation and dispersion: breaking the 8RA and New Fourth Army into small units as nuclei for combat, recruitment, political work, and base-area construction. Under this approach, few engagements could be truly dramatic in scale, and most were constrained by the need to survive. Each skirmish had to be carefully planned. The CCP would use local intelligence and the element of surprise so that a detachment could strike and withdraw before its limited ammunition ran out or before enemy reinforcements arrived. Small Japanese patrols and puppet units could be ambushed not only to seize weapons and other material, but also to inflict casualties. Active collaborators, or Japanese-sponsored administrative personnel, could be assassinated. Above all, Communist action aimed to disrupt transportation: mining roads; cutting down telegraph poles, stealing wire, and cutting rail lines; sabotaging rolling stock; and, at times, carrying off steel rails so that primitive arsenals could be supplied. Attempting derailments was also part of the effort. Destroying a bridge or a locomotive counted as a major achievement. Both the Communists and the Japanese understood that these tactics did not decisively shift the overall strategic balance. Still, they worked at other levels. For the Japanese, the result was a constant series of small wounds—painful, bleeding, and potentially infectious. Few areas in the countryside felt truly safe. Japanese field commanders documented growing frustration as they tried to eliminate resistance, restore administration, collect taxes, and prepare for more systematic and effective economic exploitation of conquered territory. Guerrilla warfare against the Japanese cannot be judged only in conventional battle terms—numbers of engagements, casualties, or territory occupied. It had to be evaluated politically and psychologically as well, exactly as Mao repeatedly emphasized. Since the CCP's wartime legitimacy depended on its patriotic claims, enough fighting had to be carried out to maintain credibility. Moreover, military success mattered for mobilizing the "basic masses," persuading wavering people to keep an open mind, and neutralizing opposition. As the logic put it, it was not that people always chose the side that was winning, but that few would ever join a side they believed was losing. One experienced cadre described the effect this way: Among the guerrilla units… there is a saying that "victory decides everything." No matter how hard it has been to recruit troops, supply the army, raise the masses' anti-Japanese fervor or win over the masses' sympathy, after a victory in battle the masses fall all over themselves to send us flour, steamed bread, meat, and vegetables. The masses' pessimistic and defeatist psychology is broken down, and many new guerrilla soldiers swarm in. But once the Japanese began to demand a heavy price for every engagement—whether the Communists won or not—this attitude began to change. In North and Central China, the Japanese earliest pacification sweeps created comparatively little trouble for the CCP. At first, the Japanese made few distinctions among Chinese forces. They simply tried to mop up or disperse them without regard to character. Over time, however, they realized that these sweeps actually made it easier for the CCP to expand. By the second half of 1939, Japanese methods became more discriminating. Chinese non-Communist forces would step aside while the Japanese hunted specifically for the 8RA, the N4A, and their local affiliates. The Japanese also made more direct appeals to non-Communist forces. According to Japanese army statistics, during the eighteen months from mid-1939 to late 1940, around 70,000 men from more or less regular Nationalist units in North China alone went over to the Japanese. The Japanese also reached informal "understandings" with several regional commanders whose forces together might have totaled as many as 300,000 men. This, of course, corresponded to what the CCP denounced as "crooked-line patriotism"—the "crooked-line" collaboration that preserved certain units so they could be used in future anti-Communist operations. When pacification efforts were intensified from late 1939 and throughout 1940, differences also appeared in the strategies Japanese armies used in North versus Central China. In North China, the approach relied heavily on military means, with political tactics limited largely to recruiting collaborators. In Central China, Japanese authorities did not hesitate to use military force, but they also attempted to supplement it with more comprehensive political and economic solutions by setting up tightly controlled "model peace zones." Although both approaches ultimately failed, they created enormous difficulties for Chinese Communists—until, in 1943, the Japanese were forced to ease off because the Pacific War against the United States became too burdensome. Careful reading of detailed intra-party documents suggests that repression also demobilized peasant support and terrorized populations into apathy, grudging acquiescence, or even active collaboration with the Japanese. In a locality already reduced from consolidated base status to guerrilla status, capacity and will were often too weak to administer complex reforms in systematic fashion. In other words, passive survival—defensive survival—was at least as important as what lay behind the heroic public images the Party projected. Systematic pacification in North China in late 1939 and 1940 radiated outward. It moved from areas held more or less firmly by the Japanese and their puppets into guerrilla and contested zones. The ultimate objective was to crush resistance or render it ineffective. The method was first to sweep the area clear of anti-Japanese elements, and then to establish a chain of interconnected strongpoints that could quickly reinforce one another. After that, puppet government would be expanded so it could take increasing responsibility for civil administration and "pacification maintenance," while Japanese forces repeated the initial steps further outward into contested territory. Violence was used selectively against individuals, groups, or villages accused of acts of resistance. This selective violence aimed to deter active participation in CCP-led programs, deprive Communist forces of a population willing to shelter them, and persuade informers to come forward. That was, at least, the theory of the strategy. In practice, the basic framework of the strategy depended on the main transport lines. Railways and roads—if properly fortified and protected—could separate resistance forces from one another and deny them one of their most effective weapons: mobility. These "cage" tactics (chiyu-lung, "jiu-lung") made it possible to enlarge pacified areas by "nibbling" outward, "as a silkworm feeds on mulberry leaves" (ts'an-shih). At the same time, the approach aimed to exploit North China's economy more effectively. To this end, the Japanese worked to improve and extend both railway and road networks. When the war began, in Shanxi the Cheng-Tai (Shijiazhuang–Taiyuan) and Tong-Pu (Datong–Tongguan) lines were metre-gauge, incompatible with the standard-gauge lines elsewhere in China—part of Yan Xishan's design to prevent deeper penetration into his province. By the end of 1939, the Japanese used forced labor to convert both lines to standard gauge. One benefit was the easier transportation of high-quality anthracite coal from the Qingxing mines (on the Cheng-Tai line) to industrial users in North China and Manchukuo. Of the newly constructed roads and railway lines, the most important was the Te-Shih line—from Dezhou in northeastern Shandong to Shijiazhuang. Construction began in June 1940 and finished in November, connecting the Tianjin–Pukou, Beiping–Hankou, and Cheng-Tai lines. This made it easier to move troops and transport raw cotton. Once the Te–Shih link was completed, the Japanese had direct connections between the point of their furthest advance at the elbow of the Yellow River and all major cities of North China, and beyond to Manchukuo. Communist sources began to speak of a "transportation war," noting with concern the moats and ditches, the blockhouses, and the frequent patrols protecting the lines. Both militarily and economically, these measures weighed heavily on forces led by the Communists in North China and on the populations under their control—especially the plains of central and eastern Hebei. One indicator of effectiveness was the rapid decline in "acts of sabotage" against North China railways in 1939 and the first half of 1940. A cadre in Jin-Cha-Ji reported in mid-1940: "The enemy has adopted a blockhouse policy, like that of the Jiangxi Soviet. They are spread like a constellation. In central Hebei alone, there are about 500, separated by one to three miles." Normal trading patterns were disrupted as Japanese or puppet occupiers took over administrative and commercial centers, and peasants found themselves caught between regulations imposed by the Communists on one side and those enforced by the other side. Finally, landlords, moneylenders, loafers, bandits—everyone who felt damaged by the new order inside base areas—could use pacification programs to try to recover influence or simply take revenge. Some became informers. After 8RA and local units were driven away, they could kill remaining cadres or activists and settle scores with the peasants who had supported them. Until the "first anti-Communist upsurge" was defeated, local elites and other disaffected elements might also seek support from Nationalists. It was even possible for an armed band to operate for several months inside consolidated regions of the CCP base, killing cadres as it went. Peng Dehuai later recalled this period in a way that underscored how pressure translated into wavering and collapse. Under the enemy's brutal pressure, in some districts the masses even hesitated or capitulated. From March to July 1940, large areas of the North China base were reduced to guerrilla regions. Before the "Cage-bursting battle",, they controlled only two county seats: Pingxun in the Taihang mountains and Pien-kuan in northwest Shanxi. Masses who previously had one set of obligations now had two—one toward the anti-Japanese regime and one toward the puppet regime. The situation in North China had not yet become a full crisis, but it was certainly serious. Action was needed to regain initiative. On 22 July 1940, Zhu De, Commander-in-Chief of the Eighth Route Army, Peng Dehuai Deputy Commander-in-Chief, and Zuo Quan Deputy Chief of Staff jointly issued the Preliminary Battle Order, laying out the strategic goals for the coming operation. The order stated: "To respond to the enemy's 'prison cage policy,' obstruct its advance toward Xi'an, create favorable conditions in the North China theater, and strike at the national resistance initiative, we have decided to take advantage of the concealment provided by tall summer millet and the rainy season to carry out a large-scale sabotage operation on the Shijiazhuang–Taiyuan railway (Zheng–Tai Line)." It required the participation of at least 22 regiments from the Jin-Cha-Ji Military Region, the 129th Division, and the 120th Division. The main objective was to "completely destroy key points along the Zheng–Tai Line" and to "cut the railway for a prolonged period." On 8 August, the headquarters of the Eighth Route Army issued the Operational Battle Order, further clarifying how forces would be deployed. The Jin-Cha-Ji Military Region was assigned to attack the eastern section of the Zheng–Tai Railway (from Niangzi Pass to Shijiazhuang). The 129th Division was assigned the western section (from Niangzi Pass to Yuci). The 120th Division was tasked with targeting the northern segment of the Tongpu Railway and the Fen–Li Highway. The order also required all troops to begin combat operations on 20 August, and emphasized that "the success of the campaign should be assessed primarily by the extent of damage inflicted on the Zheng–Tai Line." The operation was prepared under strict secrecy. Various elements of the Eighth Route Army conducted thorough preparations before the campaign. Reconnaissance teams, hidden and protected with the help of local villagers, penetrated deep into areas near the Shijiazhuang–Taiyuan railway to carefully map Japanese strongholds, enemy troop dispositions, and local terrain. At the same time, both military and civilian communities mobilized to stockpile grain, ammunition, and tools needed for railway sabotage; blacksmiths were organized to manufacture crowbars, pickaxes, and other essential equipment. Specialized military training covered demolition methods and techniques for dismantling railways, including tactics such as heating and bending steel rails. Civilian mobilization played a crucial role: militia and support teams took on tasks such as transport, medical aid, and coordination with military units. In Central Shanxi alone, more than 10,000 militia members were mobilized. The Eighth Route Army headquarters repeatedly stressed the need for operational confidentiality, stating: "Before the battle begins, the plan must remain strictly classified; until preparations are completed, the campaign objective may be disclosed only to brigade-level commanders." With the cover of dense summer millet, troops secretly assembled within their designated operational areas. Before the battle, the Japanese North China Area Army estimated the strength of the communist regular forces at about 88,000 men in December 1939. Two years later, they revised the estimate to 140,000. On the eve of the battle, communist forces had grown to between 200,000 and 400,000 men, organized in 105 regiments. By 1940, the growth had become so significant that Zhu De ordered a coordinated offensive by most of the communist regular units—46 regiments from the 115th Division, 47 from the 129th, and 22 from the 120th—against Japanese-held cities and the railway lines that connected them. According to the Communist Party's official statement, the battle began on 20 August. On August 20, 1940, the rain didn't stop the campaign—it changed the battlefield. It slowed movement, blurred distance, and turned rivers and muddy roads into obstacles that could just as easily trap your own men as your enemy's. Along the districts bordering the Zhengtai Railway, the Eighth Route Army still moved, slipping through valleys and river crossings, bypassing Japanese posts, and positioning forces on both sides of the line as night settled in. By dark, the plan became a coordinated strike meant to hit the enemy before they could properly react. Across the entire Zhengtai Railway, attacks went out with timing designed to disorient Japanese defenders—so that their "first realization" arrived only after the railway itself was already being attacked and the window to respond effectively had slipped away. A key portion of that strike fell to the right column of the Jin-Cha-Ji Military Region, centered on the 5th and 19th Regiments, with the mission of sabotaging the Niangziguan to Luanliu section. At 20:00 on August 20, part of the 5th Regiment infiltrated Niangziguan Village for the first time, overwhelmed the puppet troops stationed there, and seized the village by dawn. After that opening cut, the main force moved in to cover the engineers, destroy enemy fortifications, and blow up the Guandong Railway Bridge. When the sabotage was done, they withdrew from Niangziguan on their own initiative, leaving the enemy to deal with the destruction rather than being pulled into a long, grinding engagement. That same night, at Mohe Beach along the Zhengtai line, another action unfolded. The 1st Company of the 1st Battalion of the 5th Regiment attacked the station and was immediately met with a counterattack by Japanese forces. By dawn on August 21, the company withdrew—an adjustment, not defeat—and then attacked again the same night after crossing the Mian River. This time the enemy retreated into barracks to resist more stubbornly, with nearly 1,000 Japanese troops holding Mohe Beach. Heavy rain had swollen the river and made foot crossing nearly impossible, but the attackers seized the village west of the station and held it. On August 22 afternoon, more than 400 Japanese troops counterattacked; the main force of the 5th Regiment hit from the north bank of the Mian River in a fire assault, killing more than 50 before withdrawing the 1st Company out of the fighting. The 19th Regiment, meanwhile, took Jucheng and Irrang stations, tightening the pressure on the railway corridor. On August 23, 1940, the 5th Regiment recaptured Niangziguan and blew up the stone bridge east of the village, destroying the railway segment between Chengjialongdi and Mohetan. That night the 19th Regiment stormed Yirang Station and blew up the water tower and the railway, ensuring the disruption would not be temporary. From August 24 to 27, bridges near Yanhui—stone and wooden—were destroyed again and again. Under that continuous pressure, beginning on August 25, Japanese transportation along the Niangziguan to Luanliu section of the Zhengtai Road was cut off completely. Strongholds were left to fight more or less alone, unable to coordinate or move supplies the way they normally would. While the right column worked the railway, other forces hit the system from different angles. The Central Column of the Jin-Cha-Ji Military Region—comprised of the 2nd, 3rd, and 16th Regiments—took responsibility for sabotaging the Zhengtai Road segment from Niangziguan to Weishui and for striking the Jingxing Coal Mine area. On the night of August 20, the 3rd Regiment launched coordinated attacks on the Gangtou old mine and the Dongwangshe new mine of Jingxing, and with miners assisting, the 1st Battalion quickly stormed the new mine and annihilated part of the enemy garrison. The rest withdrew into bunkers, resisting as best they could. By the afternoon of the next day, the entire enemy force had been wiped out. Afterward, major buildings in the mining area were destroyed and most materials were removed so that the mine could not resume production for more than six months. The 3rd Regiment also captured Jiazhuang, reinforcing the idea that sabotage here meant disabling not just lines of movement, but also the flow of resources. Elsewhere, Japanese positions were disrupted in smaller, targeted strikes that still added up. After the Japanese stronghold at Nanzheng destroyed the railway between Nanzheng and Weishui, the 2nd Regiment took the eastern end fortress of the Faluling Railway Bridge, covered the engineers as they blew up a section of the bridge, and briefly occupied Caizhuang. The 2nd Battalion of the 16th Regiment attacked Beiyu on the night of August 20, annihilating most defenders, and on August 21 it covered the engineers to destroy the Beiyu Stone Bridge. Other units struck Didu and annihilated most defenders in Nanyu. By August 24, the Central Column had learned that more than 1,000 Japanese troops were stationed in Jingxing County, with additional reinforcements moving toward Nanyu and Didu. Their response was practical: detachments were assigned to watch and harass along the railway while the main force gathered in mobile positions—waiting for the next opening rather than charging blindly into concentrated strength. Meanwhile, the left column of the Jin-Cha-Ji effort—from the 2nd Regiment of the Jizhong Garrison Brigade, the Military Region Special Service Regiment, and the Pingjinghuo Detachment—focused on sabotage from Weishui to Shijiazhuang. On the night of August 20, the Pingjinghuo Detachment attacked Yanfeng and blew up the railway. The Special Service Regiment moved with massed efforts as they destroyed power lines and highways from Yanfeng to Weizhou. On the night of August 22, the Special Service Regiment attacked Shang'an Station. On August 23, the 2nd Regiment stormed Touquan Station, captured two fortresses, then withdrew from the railway line; from August 25 to 27, they destroyed the highway connecting Pingshan, Huolu, Weishui, and Yanfeng. While the main blow was falling along the Zhengtai Railway, the 129th Division was assigned raids on the western section. That area included the Japanese Independent Mixed Brigade No. 4 headquarters, a coal mine base at Yangquan, and support from Independent Mixed Brigade No. 9 from Yuci. These raids weren't only about destruction—they were meant to disorient, to create confusion over where the main pressure truly was. After the general offensive began at 20:00 on August 20, five companies of the 16th Regiment attacked Lujiazhuang Station and captured bunkers. Two guerrilla-operating companies in Yuci worked with engineers to destroy bridges between Lujiazhuang and Duanting. The 38th Regiment surprised Shanghu and Heshangzu stations, while the 25th Regiment captured Mashou Station and pushed Japanese troops toward Shouyang. The division's right-wing sabotage unit—28th and 30th Regiments of the newly formed 10th Brigade—took on sabotage on the Yangquan–Shouyang section, splitting routes on the night of August 20 to attack stations like Langyu, Zhangjing, Qinquan, and then striking additional positions with the 30th Regiment. Across that window, stations and strongholds such as Sangzhang, Yanzigou, Langyu, and Qinquan were taken, iron bridges were destroyed, and additional stations including Potou, Xinzhuang, Saiyu, Tielugou, Xiaozhuang, and Zhangzhuang were seized or disrupted. As the western sabotage deepened, Japanese response hardened—but the ability to coordinate weakened. With the Zhengtai line sabotaged, the western section came under the 129th Division's control except for a few places such as Shouyang. Fierce assaults forced Japanese forces to lose contact with each other within days. Strongholds were attacked, besieged, and then annihilated as communication and coordination broke down. The 129th Division mobilized local people to destroy railway facilities, stations, and installations using demolition, burning, and flooding, moving materials so the railway and related infrastructure were effectively erased rather than merely damaged. To cover these operations, the division occupied Shinaoshan with the 14th Regiment of the general reserve. Starting the morning of August 21, Japanese forces concentrated in Yangquan and attacked Shinaoshan daily. Enemy strength reportedly rose from more than 200 to more than 600, supported by bombing and strafing and the release of poison. The 14th Regiment held out until August 25, repelling repeated attacks, and by August 26 additional pressure came again as reinforcements increased. After six days and nights—and the annihilation of more than 400 enemy soldiers—the 14th Regiment withdrew from the main peak of Shinaoshan, continuing to contain the Japanese with smaller detachments while the main force shifted to another mission. The first phase of sabotage had succeeded, but the campaign did not allow complacency. The Japanese strengthened their presence along the railway and launched frequent counterattacks, and Japanese divisions in southern Shanxi—including the 36th, 37th, and 41st—prepared to reinforce from the north. On August 26, the Eighth Route Army Headquarters issued instructions for a second phase: continue breaking through the road, concentrate superior forces, and annihilate Japanese units smaller than a battalion that were attacking or reinforcing. In line with that guidance, the Jin-Cha-Ji Military Region ordered the Jin-You Column to keep breaking through the road on August 27 for one or two days, while the 129th Division alternated daily in breaking through. Under sustained pressure, the western section of the Zhengtai Road was basically destroyed; transportation was effectively cut off except for a few towns such as Shouyang and Yangquan. On September 2, orders were issued to conclude the Zhengtai Campaign starting from the 3rd and shift forces according to the second-step plan. As the Jin-Cha-Ji Military Region launched the Mengbei Campaign, the 129th Division shifted toward attacking invading Japanese forces, while other tasks—such as attacking the He-Liao Highway and recovering cities of He and Liao—were left for later. Beginning September 2, the Military Region deployed the 2nd, 5th, 16th, and 19th Regiments toward areas north of Meng County and Shouyang to recapture enemy strongholds. With the railway sabotaged, the Japanese main force north of Meng County shifted south to reinforce, weakening garrisons and spreading panic among the strongholds. As fierce offensives intensified, garrison troops began to waver. By the afternoon of September 5, Japanese troops at Xiashe, supported by troops from Shangshe, retreated to Shangshe and fled toward Meng County overnight. That night, the 19th Regiment arrived near Shangshe and, together with the Special Service Battalion of the 2nd Military Sub-district, pursued. The 1st Battalion of the 19th Regiment advanced into Shenquan and Putian to cut off the retreat route. By 9:00 AM on September 6 the enemy was surrounded in Xingdao Village, and after five hours of intense fighting most forces were annihilated. Survivors fled east to Luolizhang Mountain, only to be surrounded again by the 19th, 5th, and 16th Regiments. By the night of September 9, most Japanese forces had been wiped out, though more than 40 men broke through in dense fog and escaped into Meng County. The siege continued through bitter episodes involving attacks and withdrawals under poison, with both sides paying heavily for every moment of progress. Eventually, on September 11, Japanese troops in Xiyan escaped back to Meng County, helped by more than 200 Japanese already present there. Meanwhile, the Japanese attempted to counter the pressure: on September 4 they sent more than 2,000 troops to reinforce Meng County and began a counterattack. On September 10, the Jin-Cha-Ji Military Region ordered the 19th and 5th Regiments to remain east and north of Meng County to coordinate with the 129th and 120th Divisions, while the rest prepared for new missions. As fighting intensified around Zhengtai and Meng County, a parallel pressure campaign unfolded. To contain Eighth Route Army sabotage along Zhengtai, the Japanese assembled battalions from Independent Mixed 4th and 9th Brigades to strike the 129th Division. In response, the 120th Division began large-scale sabotage against the Tongpu Railway and major highways in northwestern Shanxi starting 20:00 on August 20. They captured enemy strongholds along rail and road lines, striking major bases such as Kangjiahui on the Xinjing Highway, where more than 50 Japanese and puppet troops were stationed, and also attacking other areas like Shishen, Lizhen, and Jingle. Ambushes were set to annihilate reinforcements arriving from different directions, and at 00:30 on August 21 the 2nd Battalion of the 4th Regiment attacked Kangjiahui and annihilated the defenders by dawn. Reinforcements arriving in cars were destroyed, and subsequent actions continued to expand the disruption. Over more than 180 battles in northwestern Shanxi, the 120th Division annihilated more than 800 Japanese and puppet troops and captured or destroyed stations and strongholds including Kangjiahui, Yangfangkou, Pingshe, and Longquan. By disrupting the Tongpu Railway and transportation along the Xinjing, Taifen, and Fenli highways, they tied down Japanese forces and made it harder to reinforce Zhengtai. In practical terms, this meant the first phase of the Hundred Regiments Offensive—lasting about three weeks—ended on September 10 with major railway lines and motor roads attacked repeatedly. Roadbeds, bridges, switching yards, and installations were hit heavily; at the Qingxing coal mines, facilities were destroyed and production was halted for nearly a year. By the end of that first phase, the campaign's logic had become clearer: once the Japanese leaned more heavily on a "cage-and-strongpoint" defense system, the same transport network that had supported their defense became less secure. When rail and road were repeatedly disrupted, strongpoints became more vulnerable—especially if Japanese units pulled out nearby detachments to respond to sabotage. So the campaign shifted from breaking transportation to attacking blockhouses and other strongpoints in contested areas, aiming to force Japanese forces back into well-defended garrisons and leave the countryside again contested by Communist forces.

If you are still hungry after that, give my personal channel a look over at The Pacific War Channel at Youtube, it would mean a lot to me. From 20 August 1940, under secrecy and rain, units of the 8th Route Army infiltrated stations, captured villages, destroyed bridges, power lines, roads, mines, and stations across multiple columns. By early September the Zhengtai and related Tongpu transport routes were repeatedly severed, forcing Japanese troops to fight isolated strongpoints and hindering reinforcement.
