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.

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.

3.201 Fall and Rise of China: New Fourth Army Incident and the Strained United Front

Last time we spoke about the battle Yaoyi. Japan pushed hard into Hubei with a plan: surround the main Chinese forces and seize Yichang, hoping to use it to strike at Chongqing. At first, the fighting was chaotic and punishing. The Chinese side tried to hold the line and disrupt the advance, and they even managed setbacks for the Japanese, pushing back, retaking key ground, and hitting supply and positioning weaknesses. But victory came with a cost: commanders were lost, and every gain was hard-won. Still, the battle didn't unfold as a clean Chinese retreat or a simple Japanese win. As Japanese units shifted and tested for openings, the Chinese forces adjusted—delaying, regrouping, and fighting to keep their formations from being completely trapped. Eventually, Japan managed to break through at critical moments, especially through crossings and maneuvers that the Chinese had not fully sealed off. In the end, Japan succeeded in taking Yichang, but it didn't achieve the decisive annihilation it wanted. #201 The New Fourth Army Incident and the Strained United Front 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 catastrophe of the early 1930s, the Chinese Communist Party (CCP) entered the war against Japan in a political mood that was both hopeful and wary: it wanted to be seen as a genuine national leader of resistance, yet it also feared being absorbed—or destroyed—by the Guomindang (KMT) state it had spent years battling. That tension became the organizing principle of the war's early years. The turning point came from the Xi'an Incident in December 1936, which forced a new calculation in Nationalist politics. In the months that followed, agreements between KMT and CCP representatives were publicly proclaimed in August and September 1937, after the Shanghai fighting began. Under these arrangements, the CCP accepted constraints that in peacetime would have looked like surrender: it pledged to strive for Sun Yixian's "Three People's Principles," to end its former policies of armed revolt and sovietization, to abolish the soviet government, and to discontinue both the term "Red Army" and the expectation that its forces would operate outside central control. Communist troops would be treated as part of the national military under KMT command, and the revolution's old administrative structures were to be formally dismantled. In return, the KMT offered the CCP something just as important: space to exist publicly and politically. Liaison offices were permitted in key cities; the CCP was allowed to publish the New China Daily; and it could nominate representatives to KMT advisory bodies. Civil rights were extended—political prisoners were released—and subsidies were established to help cover administrative and military expenses in "reintegrated" areas and territories. The war thus transformed the tactical reality on the ground: the CCP could not treat the KMT as an immediate enemy, but it also could not afford to become politically passive. It had to learn how to fight Japan while building legitimacy fast enough to survive the next phase. In the first year and a half, the Party Center focused on three problems that kept returning in different forms: how the "united front" would be defined—especially what the CCP's relationship to the National government should be; how to coordinate military strategy and tactics with Nationalist units without losing control of its own operations; and how leadership should be consolidated, particularly for Mao Zedong in a party that still contained rival centers of authority. These disputes mattered not just for doctrine but for survival, because the CCP's autonomy was constantly being tested by the very alliance that was supposed to protect it. Mao's own approach to the united front combined cooperation with a refusal to surrender independence. Publicly, the CCP praised Jiang Jieshi and the KMT and promised unity, but it did so in language that was deliberately broad. In private (and in internal party debates), Mao treated unity as conditional: the CCP must not split the united front, but it also must not be "bound hand and foot." The strategic idea that emerged was political initiative under constraints—fighting when it could plausibly claim justification, keeping enough restraint that the CCP would not appear self-interested or anti-national, and deciding for itself when to engage and when to withdraw. This balance was reinforced through military reorganization. In August–September 1937, CCP forces were reorganized as the Eighth Route Army (8RA), with roughly 30,000 men drawn from Long March survivors, local forces, and new recruits. The 8RA was divided into three divisions: the 115th, 120th, and 129th, commanded by Lin Biao, He Long, and Liu Bocheng respectively. Shortly after the war began, the National government also authorized a second major Communist force: the New Fourth Army (N4A), to operate in central China. Its core came from those left behind when the Long March began in 1934—small groups surviving in difficult conditions against continuing KMT pressure. Officially authorized at 12,000, it took months to reach that strength. Nominally commanded by Ye Ting, actual military and political control rested with Xiang Ying and Chen Yi. From the start, then, the CCP's wartime "integration" with the National system coexisted with a clear effort to preserve internal control. Ideologically, the CCP worked to make its revolutionary program compatible—at least in appearance—with a national resistance coalition. On the New Democracy demonstrated how this strategy operated on two levels. In KMT-controlled spaces, its language could be read as aligning with liberal-democratic expectations: public participation, multi-party governance, legally protected civil rights. But in CCP-controlled areas, the same text could carry sharper class-based and authoritarian implications. The Party wanted a united front that broadened support without becoming committed to Nationalist limits on how society itself might be reorganized after victory. Meanwhile, even as the rhetoric of unity rose, the CCP worried about something more dangerous than military setbacks: the possibility that the KMT might accommodate Japan. Late 1939 and early 1940 made this fear harder to dismiss. Japan pursued collaboration with Wang Jingwei, culminating in the establishment of a "reorganized" government at Nanjing in March 1940. At the same time, Japanese intermediaries sought approaches to Chiang Kai-shek himself—an effort that the CCP tracked closely as a sign that peace negotiations might be possible even when battlefield conditions looked grim. Propaganda was involved, but the anxiety was real: if Japan and the Nationalists reached an arrangement, the CCP's whole wartime legitimacy-building effort could collapse overnight. As a result, the united front was interpreted inside the CCP not as a permanent coalition with the KMT, but as a flexible strategy with a cardinal purpose: to prevent peace between Japan and the Nationalists. Mao's position on the united front reflected this. For him, the alliance was meant to suspend the possibility of a China–Japan settlement, not to end the CCP's separate identity. The CCP could participate in a reconstituted national framework—possibly even a "democratic republic"—to gain legality and influence, but it should remain politically and, where possible, physically separate from the KMT. By 1939, however, the practical meaning of "flexibility" collided with reality. What had seemed, to some observers, like an unusually cordial entente began to fade. The KMT Central Committee adopted measures early in 1939 aimed at restricting Communist expansion, and armed clashes increased through the summer and continued into autumn and winter—especially around North China Communist bases. The period of rising conflict was later labeled by the CCP as the "first anti-Communist upsurge" (roughly spanning December 1939 into March 1940), but the crucial point was that both sides viewed each confrontation as a test of legal rights, moral legitimacy, and control over territory. Strategically, the CCP understood the KMT's effort as an attempt to check unauthorized growth of Communist armed power and to recover areas where influence had already slipped away—either to the Communists or, by indirect effect, to Japan. The KMT emphasized its traditional legal authority; the CCP countered with its claim to an "evolutionary" moral right to challenge the government's legitimacy. In practice, the conflict took the form of increasingly systematic military pressure, including a blockade around the Shen–Gan–Ning region. By this point, the blockade involved large numbers of troops (on the order of hundreds of thousands), halting Communist expansion and disrupting direct contact with other Communist forces farther afield, even as fighting flared along border zones and around vulnerable points in the Communist defensive perimeter. So, by the edge of the "middle years," the wartime alliance had not broken into open civil war—but it had also stopped being secure. The united front survived, yet it operated under strain: its language of cooperation continued, while "friction" between partners hardened into a central feature of the resistance struggle. Transition into the war's second phase began in early 1939, shaped by the stalemate Mao had already anticipated at the sixth plenum in late 1938. Mao argued that during this prolonged "new stage" the forces of resistance—above all, Communist-led forces—would strengthen. The overall result, however, was mixed. In Shandong and Central China, new Communist bases did take shape. But across much of North China, Japanese consolidation cost the resistance heavily in manpower and population. Base-area economies suffered serious strain, and the peasantry endured hardships more severe than at any earlier point. This stalemate had two main dimensions. The first was the growing resentment of the Nationalists toward Communist expansion—resentment made especially sharp by their own losses. As the Nationalists were driven out of regions that had previously provided them their greatest wealth and power in the central and lower Yangtze basin, they also lost the "cream" of their armies. In contrast, the CCP was spreading through the wider countryside behind Japanese lines, extending its influence and winning broader popular support. The second dimension was Japan's desire—and need—to consolidate territories it had only nominally conquered and to extract economic value from them. After all, the logic of the "China Incident" was to draw on China's labor and resources to strengthen Japan, not to bleed Japan's gains away by draining wealth into China's vast interior. A Japanese colonel, lamenting the situation, captured the frustration of this drift into deeper entanglement: he regretted that Japan had not ended the "China Incident" once its initial objectives were reached. Instead, Japan was drawn into the hinterland and became bogged down in endless attrition—leaving it with little more than "real estate" rather than the popular support it believed it would secure from those it claimed to "liberate." To improve their position, Japanese authorities—still fragmented by internal rivalry—pursued several strategies. One was a new peace offensive aimed simultaneously at Jiang Jieshi, alongside efforts to establish a "reformed" Nationalist government under Wang Jingwei, who had fled Chongqing in December 1938. Japan also recruited more collaborators and puppet officials. Finally, it carried out forceful military, political, and economic measures intended to establish effective territorial control and eliminate opposition. During the middle years of the war, the Communists described their conflicts with the Nationalists using the euphemism "friction". By 1939, what many observers—possibly incorrectly—had viewed as an unusually warm alliance began to break down. In early 1939, the KMT Central Committee adopted measures meant to restrict the CCP. From the summer onward, military clashes began and continued into autumn and winter with increasing frequency and intensity, most of them concentrated around and within the North China base areas. The Communists later labeled the period from December 1939 to March 1940 the "first anti-Communist upsurge." Naturally, each side accused the other of aggression and claimed self-defense against unjust attacks. Strategically, though, the North China "upsurge" functioned as a Nationalist attempt to limit the CCP's expansion beyond the areas assigned to it and to regain influence in regions the Communists—or the Japanese—had already taken from the KMT. Jiang Jieshi framed the matter as a defense of legal rights grounded in tradition, while the Communists asserted an "evolutionary" right to challenge the moral legitimacy of those legal claims. During 1939, the Nationalists began to blockade Shen–Gan–Ning around its southern and western perimeter. Within a year, this blockade grew to nearly 400,000 troops, including some of the last remaining Central Army units under the command of Hu Zongnan. The blockade stopped further Communist expansion, especially into Gansu and Suiyuan, and severed direct contact between SKN and Communists operating in Xinjiang (Chinese Turkestan) adjacent to Soviet Central Asia. The Xinjiang Communists—including Mao Zedong's brother—were eliminated in 1942. Meanwhile, fierce fighting erupted along the Gansu–Shaanxi border and in the north-eastern corner of SKN near the Great Wall at Suide, as the blockading forces probed for weak points. Elements of He Long's 120th Division were even pulled back from the Jin–Sui base across the Yellow River to strengthen SKN's regular defenses. Economically, the blockade was even more damaging. During 1939, central government subsidies to the Border Region budget were cut off. Trade between the Border Region and other parts of China nearly stopped, a devastating blow to a region unable to supply itself with many basic commodities. At the same time, Nationalist and regional forces also attempted to expand their military and administrative authority into Hebei, Shanxi, Henan, and Shandong—areas the CCP now considered its base zones. In resisting these efforts, the CCP predictable accused its rivals of harming resistance work and damaging the people's interests. The "experts in dissension" were said to cooperate with the Japanese and their puppets. Based on increasing collaboration by regional units with Japan, the CCP implied that this was a deliberate and cynical strategy—described as "crooked-line patriotism"—intended to preserve those units for future anti-Communist operations. Even so, the CCP tried to avoid an open break with the Nationalist regime in Chongqing. In public, it consistently portrayed these clashes as being initiated by local commanders acting beyond orders from higher authority—despite knowing this depiction was false. Jiang Jieshi, unable to refute the claim outright, effectively permitted it to serve as the justification for a firm Communist response. Mao Zedong outlined the general resistance policy as "justification, expedience, and restraint". The CCP was to fight when it could claim justification and when it could gain advantage, but not to press attacks beyond what the Nationalists would tolerate or in ways that could damage its image as selfless patriots. Communist forces were expected to keep initiative as much as possible in their own hands—deciding when to engage, whether to engage, and when to disengage. The most striking episode of the "first anti-Communist upsurge" was the rupture with Yan Xishan in December 1939. Tensions in Shanxi had been rising throughout the summer and autumn, as Yan and his conservative supporters—associated with the "Old Army"—linked the Sacrifice League and the Dare-to-die Corps of the "New Army" with Communist forces. When base areas and Japanese occupation eventually took over much of his province, Yan was forced into exile at Qiulin across the Yellow River in Shaanxi. In November, Yan ordered his Old Army to disarm the Dare-to-die forces with help from central units dispatched by Hu Zongnan. In the bloody fighting that followed, these elements gradually broke free of even nominal provincial control and fully completed their connection with Communist forces. More than 30,000 people went over to the Communists. One KMT intelligence agent described the process with bitterness and a sense of inevitability: the Communists were first "full of sweet words," flattery, and distortions designed to open things up and conceal their actions. But once they had fully entrenched themselves, and once the low-level base had been established, they turned and bit. The agent suggested they had suspected things might end this way, but were not aware how quickly events would move—or that it could happen precisely while Communist calls for "united front" and "maintenance of unity for resistance" filled the air. About a month later, in February and March 1940, elements of the 8RA beat back this so-called upsurge. Zhang Yinwu's forces were disarmed and dispersed across the plains of north Hebei. To the south, Chu Huaiping and Shi Yusan were pushed out of the base area, as was the KMT-appointed provincial governor Lu Zhonglin. Although some non-Communist forces remained in the region, the CCP's and CCLY bases were never again seriously threatened by forces affiliated with the central government. Reinforcing the CCP's accusations, Shi Yusan was later executed in 1940 by the central government for collaboration with the Japanese. By late 1939, CCP central authorities maintained that the areas where the CCP could expand its armed strength were mainly limited to Shandong and Central China. In those regions, the CCP continued trying to carve out bases where they could operate. The situation in Shandong was complicated. After the Japanese invasion, most Nationalist-affiliated forces stayed in the province, while Communist forces and bases were weaker and more scattered than further west. Only in late 1938 did major 8RA units from the 115th and 129th Divisions—led by Xu Xiangqian and Luo Ronghuan—enter Shandong to link up with the Shandong column and local guerrillas, including survivors of a large band recently decimated by the Japanese. Even with these efforts, Communist actions led to clashes not only with Japanese forces but also with various Nationalist-affiliated groups—groups that were stronger than the Communists at the time. Until late 1940, the CCP's clashes with Nationalist forces in Shandong were actually bloodier than clashes with the Japanese. The CCP understood that its Chinese rivals mistrusted one another, and that their attitudes toward the CCP varied widely. The main Nationalist forces were often not tightly affiliated with Chiang Kai-shek or the central government. Instead, they operated under independent—and at times disgruntled—regional commanders. Communist tactics were expressed through slogans emphasizing ways to win support and isolate hardliners: develop progressive forces and win over fence-sitters while isolating "die-hards"; flatter top echelons, enlist the middle ranks, and hit the rank and file; and win over Yi Xuezhong, isolate Shen Honglie, and eliminate Qin Qirong. Still, unlike other North China base areas, the Communists were unable for several years to neutralize Nationalist forces in Shandong. Even if Japanese mop-up campaigns had not weakened those Nationalists, the text suggests the Communists may still have struggled to do so. By November 1940, Xu Xiangqian claimed meaningful progress while admitting Shandong had not yet become a fully consolidated base. CCP successes were greatest along parts of the Shandong–Hebei border, around the Taishan massif in central Shandong, and near the tip of the peninsula far to the east. Elsewhere, "progressive forces" remained weak. Communist regular troops numbered about 70,000, which was far below the party center's goals of 150,000 regulars and between 1.5 and 2 million self-defense forces. Moreover, systematic economic reforms had barely begun. The CCP relied on familiar practices—confiscations, collections of "national salvation grain," contributions, and loans—alongside a conventional taxation system adjusted to favor poorer peasants. Communist expansion in Central China was even riskier, with a greater likelihood of large-scale conflict with central government forces than in the north. In much of North China, "friction" came primarily from rapid Communist expansion into areas with partial vacuums. In Central China, however, base-building required displacing an existing Nationalist military-administrative presence closely tied to Jiang Kai-shek and the Chongqing government. The burden of this expansion was carried mainly by the 6th Detachment (northern Anhui and Jiangsu) and the 5th Detachment, which was reinforced by 15,000 to 20,000 8RA troops under Huang K'o-ch'eng. As Chen Yi's 1st Detachment crossed from south to north through the corridor provided by Guan Wenwei's local forces, it became actively involved as well. This expansion—driven by increasingly urgent directives from Mao and Liu during the latter part of 1939 and into 1940—brought the N4A north of the river into ever more frequent and sharper clashes with Nationalist authorities in Anhui and Jiangsu, especially with units under Jiangsu governor Han Deqin. South of the river, though, Xiang Ying did not directly challenge Chongqing's commanders. Mao later charged that Xiang Ying may have been influenced by Wang Ming, or else he may simply have seen no realistic alternative. His forces—three detachments plus a headquarters unit—were heavily outnumbered by Qu Chutong's Nationalist units, not to mention Japanese forces and their puppets. Even if Mao insisted bases could be built "anywhere," the Shanghai–Hangzhou–Nanjing triangle was especially difficult terrain. Xiang Ying and his followers had survived with extraordinary tenacity in the mountains of South China between 1934 and 1937, enduring brutal search-and-destroy operations that were not lifted until the war began. It therefore seems unlikely that such survivors would suddenly become "right-wing capitulationists." Yet by spring 1940, Mao was pressing Xiang Ying more intensely. The Central Committee's message was explicit: expansion was necessary in all cases. It meant reaching into all enemy-occupied areas rather than being bound by the Kuomintang's restrictions—going beyond Kuomintang limits, not waiting for official appointments, not depending on higher-ups for financing, and instead expanding armed forces freely and independently. It also meant setting up base areas without hesitation, independently mobilizing the masses in those areas, and building united front organs of political power under Communist Party leadership. The struggle between Nationalists and Communists involved more than contests for control of territory behind Japanese lines. It also involved national-level politics, ideology, and leadership. One worrying development for the CCP was the campaign throughout 1939 to expand Jiang Kai-shek's prestige and formal power—adding more titles for him across major party, government, and military positions. In early 1939, the Central Executive Committee appointed him "director-general" of the Kuomintang, a title reminiscent of the one previously held by Sun Yat-sen. In addition, during the summer and autumn of 1939 there was talk of constitutional rule. In November, the KMT announced plans to convene a constitutional assembly the following year. If Jiang could fulfill these promises, he and his government could gain new legitimacy and wider popularity. Mao and his colleagues could not allow this to go unchallenged. If the Nationalists were to have a paramount leader and authoritative spokesperson, the CCP needed one as well. The timing of Mao's famous "On the new democracy"—written in late 1939 and published the next January—was therefore no accident. Its substance had been anticipated earlier, but its final timing and full development were shaped by the KMT's constitutional movement. The CCP's entry into this competition served as both a bid for support away from the KMT and a statement of the multi-class united front that the CCP wanted to lead. Although "On the new democracy" was written in a tone that seemed moderate, it persuaded many Chinese readers that the CCP had either diluted its revolutionary objectives or postponed them to a distant future. In Kuomintang-controlled areas, the work could be read through the liberal values associated with Anglo-American democracy—popular participation, multi-party government, legally protected civil rights. In CCP-controlled territories, the same language carried stronger authoritarian, class-based meanings. In internal documents meant for party audiences rather than public consumption, the ambiguity was removed, showing a tough but patient and flexible commitment not only to resistance but also to social control and social change. During this same period, the Communists expressed deep concern about Nationalist capitulation to Japan—not only on the battlefield behind Japanese lines but also at the highest levels. Some of this concern was propaganda, but beneath propaganda lay genuine anxiety. In late 1939 and early 1940, politically aware Chinese already knew that Japan was negotiating with the unpredictable Wang Jingwei, who had fled Chongqing a year earlier. A "reorganized national government" in Nanjing was finally established in March 1940, representing the most formidable collaboration with Japan to date. Less well known, but equally important, was that Japan was also seeking an understanding directly with Jiang Kai-shek through intermediaries in Hong Kong. This effort, called "Operation Kiri"—described as spreading a "feast for Chiang"—combined intrigue with a kind of dark comedy. Reports suggested Chiang's reported interest in peace could have been a stratagem designed to discredit Wang Jingwei by keeping him waiting. But even if Chiang had no intention of coming to terms with Japan, the Communists could not be sure what the outcome would be until after the multi-pronged peace offensive had failed. By the middle of 1940, China had never been so isolated. In Europe, the "phony war" ended in the spring when Germany launched a blitz across the Low Countries. France fell soon after, and England appeared likely to be next. Japan used this moment to press China to sever its last tenuous connections to the outside world: cutting the Burma Road, trade with neutral Hong Kong, and the rail link running from Hanoi to Kunming. At the same time, Russia was engaged in a difficult and embarrassing war with Finland and reduced military aid to the Nationalists. The United States was only gradually moving away from isolationism and clearly regarded England as more important than China. In Chongqing and elsewhere in "Free China," signs of war weariness, despair, and demoralization were visible. Under these circumstances, Mao's insistence on aggressive expansion was a calculated risk—either it would deter any Japanese advance, or it would place the Communists in the strongest possible position in case a split between the KMT and the CCP became unavoidable. In Central China, the size and pace of the fighting kept increasing, starting in the final months of 1939. One flashpoint was the clash between Luo Pinghui's 5th Detachment and units of Han Deqin's Jiangsu force near Lake Gaoyou. In the following months, Guan Wenwei's forces ranged along the left bank of the Yangtze, repeatedly running into Luo's troops as they operated farther north. Luo also began receiving some 8RA reinforcements, moving them south through areas controlled by the 6th Detachment. Clearly, a major showdown was taking shape across north and central Jiangsu. At the same time, the South Yangtze Command was doing poorly. Nationalist commanders Leng Xin and Qu Chutong restricted its activities so severely that Mao and Liu gradually abandoned the idea of building a unified, consolidated base in that region. During late spring and early summer, Chen Yi moved most of his 1st and 2nd Detachments north of the Yangtze. In September, the 3rd Detachment followed suit, crossing the river into the area around Lake Chaohu, where the 4th Detachment was already stationed. After these moves, only the Headquarters Detachment—under Ye Ting and Xiang Ying—remained south of the Yangtze, positioned at Qingxian in southern Anhui. As the military situation edged toward an open confrontation, negotiations began in June 1940 between representatives of the KMT and the CCP. The core issues were Communist operating zones and the authorized strength of the armies led by the CCP. Proposals were exchanged, followed by equally sharp and hostile counter-proposals, but no agreement was reached. The KMT viewed it as a concession to permit the CCP "free rein" north of the pre-1938 course of the Yellow River, with the exception of southern Shanxi, which was to remain under the influence of Yan Xishan. In exchange, the KMT demanded that all 8RA and N4A units evacuate Central China. In effect, the KMT was offering the CCP something it was already prepared to allow, in return for the CCP giving up what it might soon be able to obtain by force of arms. Nationalist authorities then issued a set of deadlines, but without clearly stating what would happen if those deadlines were violated. On the surface, the CCP appeared to be complying in part. The movements of Chen Yi and the South Yangtze Command could look like obedience, but in reality they were responses to orders coming from their own superior leadership rather than instructions issued by the Nationalists. Even so, Xiang Ying's continued delays and evasions during the autumn and winter of 1940 remained puzzling. One possibility is that he felt—quite reasonably—that Mao had already lost confidence in him and that once he crossed to the north bank of the river he would lose his command. Another complication was that directives from Yan'an were sometimes ambiguous and even contradictory. He may also have been trying to reach secure understandings with KMT commanders about evacuation routes and guaranteed safe conduct out of the area. For a period, Han Teqin kept most of his forces—estimated at about 70,000 men, far outnumbering the N4A—in north Jiangsu, thereby blocking the expansion of the 6th Detachment and slowing further southern intrusions by 8RA troops. But by mid-summer he realized he would have to counter the N4A build-up in central Jiangsu, or else risk writing that region off to the Communists. A confusing sequence of engagements then unfolded, culminating in a decisive battle in early October 1940 near the central Jiangsu town of Huangjiao. Over the course of four days, several of Han's main-force units belonging to the 89th Army were destroyed, while others were scattered. That battle also served as a signal for the 6th Detachment to advance more aggressively in the north. In the aftermath, one of Han's principal commanders entered collaboration with the CCP, while another defected to the Nanjing government under Wang Jingwei. Although Han Teqin managed to maintain a foothold in Jiangsu until 1943, his real power had been broken. Relatively little attention was paid to the battle of Huangjiao in the Chinese press. The KMT did not want to publicize what it considered a disastrous defeat, while the Communists were satisfied to stay silent about an episode that conflicted with their proclaimed policy of a united front. As could be expected, during the autumn—after Han Teqin's defeat—KMT-CCP negotiations deteriorated further. In early December, Jiang Kai-shek personally ordered that all N4A forces withdraw from southern Anhui and southern Jiangsu by 31 December. He also ordered that the entire 8RA be positioned north of the Yellow River by the same deadline, followed one month later by the N4A. Discussions then followed between Ye Ting and Qu Chutong's deputies concerning the route to be taken, safe conduct, and—astonishingly—the money and supplies that were to be provided to the N4A to help it move. On 25 December, Mao Zedong ordered Xiang Ying to begin evacuating immediately. Yet it was not until 4 January 1941 that Ye and Xiang actually started moving. Almost immediately, Qu Chutong's forces harassed and dispersed the N4A Headquarters Group, which included administrative personnel, wounded soldiers and dependents, as well as combat-ready troops. In an attempt to reorganize, they moved southwest toward Maolin, where they were surrounded by Nationalists and, over the next several days, were cut to pieces. Losses were heavy on both sides. The CCP suffered an estimated 9,000 casualties. Xiang Ying tried twice to break out of the blockade on his own, but failed. He was then denounced as a deserter by Ye Ting, who took over full command of the doomed forces. Xiang Ying eventually escaped, but he was killed a couple of months later by one of his own bodyguards, motivated by the N4A gold reserves that he had taken with him. Up to the very end, Xiang either failed or refused to seek refuge in Liu Shaoqi's domain north of the Yangtze. The unfortunate Ye Ting was arrested and spent the rest of the war in prison. He was finally released in 1946, only to die one month later in a plane crash, along with several other high-ranking party members. On 17 January, Jiang Kai-shek declared that the New Fourth Army was dissolved for insubordination. Direct contacts between Yan'an and Chongqing nearly came to an end, and CCP military liaison offices in several cities held by the Nationalists were closed. This is what became known as the New Fourth Army incident, also referred to as the South Anhui incident. Clearly, it functioned as an act of retaliation for the defeats suffered by Han Teqin in north and central Jiangsu. It ended any realistic prospect of establishing a consolidated Communist base south of the Yangtze. Still, from a strategic perspective, these losses were ultimately more than offset by the gains achieved farther north. In fact, only a few months later, the reorganized N4A quietly began reintroducing some units into this region, where they carried out guerrilla activities without possessing a secure territorial base. Unlike the relative silence surrounding the fighting at Huangjiao, the New Fourth Army incident sparked bitter, prolonged controversy. The CCP argued that it was a second "anti-Communist upsurge," even more serious than the first. Presenting themselves as martyred patriots, they depicted their opponents as people who wanted to end the War of Resistance through what they called "Sino-Japanese cooperation" aimed at "suppressing the Communists." In their account, the Nationalists wanted to replace the war of resistance with civil war, substitute capitulation for independence, trade unity for a split, and replace light with darkness. People were telling each other the news and were horrified. Indeed, they claimed that the situation had never been as critical as it was at that moment. The Nationalist response, of course, was that provocations had been numerous and serious, and that violations of military discipline could not be tolerated. But the KMT's unwillingness to describe in detail its own defeats at the CCP's hands left it speaking in broad generalities. In the propaganda battle, the CCP clearly gained the better position and won more political capital. If it was politically valuable to be regarded as a national hero, it was even more valuable to be seen as a national martyr. Many Chinese—and some outside—observers were genuinely alarmed and feared that civil war might openly resume. Yet, with a few exceptions, the events that culminated in the New Fourth Army incident have generally been interpreted as marking the breakdown of the second united front. That interpretation, however, is described as being wrong in two respects. First, the CCP understood the united front not as a narrow arrangement limited to a few major partners, but as a strategy that could be applied flexibly to all political, military, and social forces in China—from the highest levels of the central government down to the smallest village. Relations with Jiang Jieshi and the Guomindang regime mattered, but they did not, by themselves, constitute the whole of the united front. Even regarding Jiang and the Nationalists specifically, the common reading is said to be misguided. Throughout the war, a cardinal objective of the united front was to prevent peace between Japan and the Nationalists. Therefore, if clashes between CCP forces and those of the central government on such a large scale as at Huangjiao and Maolin could occur without leading to peace with Japan and without triggering a full-scale resumption of civil war, then this should not be understood as the end of the united front—it should be seen as its fundamental vindication. If friction at that scale could nevertheless be tolerated by Jiang Jieshi, then fears about his future accommodation with Japan were greatly reduced. Following the New Fourth Army incident, the CCP reorganized its political and military presence in Central China. The Central Plains and South-east China Bureaus were merged and renamed the Central China Bureau, with Liu Shaoqi placed in charge, reflecting the area's importance to Party Central. The New Fourth Army was also reorganized completely and substantially regularized. Chen Yi became its new acting commander, since Ye Ting was imprisoned. He directed the force, now divided into seven divisions. Each division had territorial responsibilities, and in each region the CCP claimed the establishment of a base. Indeed, base construction proceeded in earnest only after the friction of 1940 and the New Fourth Army incident. In the years that followed, the operating areas of the First through Fourth Divisions contained expanding enclaves of consolidated territory, where military dominance was joined with open party work: administrative control, the development of mass organizations, local elections, and socio-economic reforms. The other three areas fluctuated between semi-consolidated and guerrilla status. With the incident, the worst phase of the KMT-CCP conflict was now over. When CCP documents later speak of a third upsurge in 1943, they refer to something openly political. With the exception of Shandong—where a fairly strong Nationalist presence persisted for a longer time—the overall balance of power among Chinese forces behind Japanese lines had shifted in favor of the CCP by mid-1941. In subsequent years the CCP's predominance became even more pronounced, until by the end of 1943 the Communists were virtually beyond challenge by Chinese rivals.

After the CCP and KMT entered the united front, cooperation felt conditional from the start. Mao pushed the New Fourth Army to reorganize and preserve Communist autonomy, even as the 1937 agreements publicly pledged obedience to KMT leadership. In 1939–40 the Communists worried that Chiang might negotiate peace with Japan; so they expanded bases and military presence, triggering repeated clashes. The pressure intensified when KMT orders forced the New Fourth Army to evacuate south Anhui in late 1940.

3.200 Fall and Rise of China: The Battle of Yaoyi

Last time we spoke about the battle of West Suiyuan. The Ma Clique, Muslim warlords controlling Northwest China, led by Ma Hongkui and Ma Hongbin, rebuffed Japanese overtures to ally, citing historical grievances like the 1900 invasion. Driven by patriotism, they aligned with the Nationalists, reorganizing forces into the 17th Army Group. In 1938, Ma Hongbin commanded West Suiyuan defenses, building fortifications in harsh desert and mountain terrain, blending cavalry tactics with modern training despite equipment shortages. In January 1940, Japanese and puppet troops advanced from Baotou, occupying Wuyuan and Linhe. Chinese forces, including Fu Zuoyi's 35th Army and Ma's 81st Army, employed guerrilla and mobile warfare. A major counterattack in March recaptured Wuyuan, killing Lt. Gen. Mizukawa and thousands, forcing Japanese retreat. Through ambushes and night raids, the Chinese recovered territories, securing Soviet aid routes and the Shaanxi-Gansu-Ningxia region. Over 2,000 Ningxia soldiers perished, their sacrifices underscoring peripheral fronts' role in national resistance. #200 The battle of Yaoyi 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 capturing Wuhan, the Japanese army had already stretched itself dangerously thin. Most regular and Class A reserve divisions were committed to the front, yet they failed to annihilate the main Chinese force. Despite losing its core industrial and resource regions, the Nationalist government in Chongqing refused Japan's peace terms. Japan now found itself trapped in the very protracted war it had desperately sought to avoid. The logical Japanese response was to halt major advances, consolidate control over occupied areas, and conduct limited offensives to pressure Chiang Kai-shek into negotiations—essentially repeating the post-Nanjing strategy of late 1937. But the situation had deteriorated sharply: occupied territory had at least doubled, Japanese garrisons were inadequate, and strategic reserves were nearly exhausted. What might have been prudent a year earlier had become plainly unwise by late 1938. To stabilize the front, Japan reorganized its China Expeditionary Army at the end of 1938. Large numbers of newly raised independent mixed brigades and lower-quality Class B reserve divisions were sent to relieve veteran regular and Class A divisions. The relieved units were either demobilized back to Japan or shifted north to reinforce the Kwantung Army against the Soviet threat. By early 1940 Japan maintained roughly 24 divisions, 21 independent mixed brigades, and 2 cavalry brigades in China proper (excluding Manchuria), totaling nearly 800,000 ground troops. The enormous scale and expense strained the home economy severely. Even so, the vast occupied zones could not be effectively controlled: divisions often held only a single mobile battalion while dispersing the rest into scattered platoon- and squad-sized outposts. Guerrilla activity by both Nationalist and Communist forces not only persisted but intensified, occasionally clashing with each other in "friction" incidents. Beyond mere occupation, Japan sought to wear down Chinese strength. With most elite Central Army units held in reserve in the southwest or around Wuhan, Japanese local offensives targeted the Fifth and Ninth War Zones, aiming to methodically destroy Chiang's best troops. Thus, while other Japanese armies focused on garrison relief and brigade substitution, the 11th Army—still holding Wuhan with seven divisions and three brigades—remained the main offensive instrument. In 1939 it captured Nanchang, then mounted major operations against the Fifth War Zone (Suizao Campaign) and Ninth War Zone (First Battle of Changsha). Except for the seizure of Nanchang, however, these offensives inflicted only limited and temporary damage on Chinese forces. Japan's domestic economy was in even worse shape. In early 1937, it had approved a massive 2.4 billion yen naval and army rebuilding program aimed at countering the United States and Russia, but implementation had barely started when the Sino-Japanese War erupted. The conflict generated enormous war costs while military expansion continued unabated, rapidly draining the Bank of Japan's gold reserves. By the end of 1938, those reserves (valued at just 1.35 billion yen) had shrunk by more than two-thirds. To fund the Battle of Wuhan that year, Japan postponed key elements of the rebuilding plan. After Wuhan fell, the Army revised its wartime reorganization: the original target of forty divisions grew to fifty-five by early 1938, then to sixty-five divisions plus 164 Army Air Force squadrons by 1942. The funding required to equip and stockpile for this expansion escalated steadily; the 1939 expansion budget alone demanded 1.8 billion yen, pushing Japanese finances to the breaking point. Japan repeatedly sought a way out of China, but its peace terms remained far beyond what Chongqing would accept, leaving negotiations stalled. Efforts to install puppet regimes in North and Central China—culminating in the Wang Jingwei government in 1940—aimed to "use Chinese to control Chinese" and undermine Nationalist influence, yet produced disappointing results. The 11th Army's 1939 campaigns yielded only mediocre outcomes, hampered by chronic troop shortages. Even its divisions were tied down in occupation duties; mounting a serious offensive required pulling garrison forces, leaving no reserves to hold the line unless new units arrived. Sustained large-scale operations to seriously weaken Chinese strength demanded a major troop increase—otherwise, Japan was limited to shallow, localized attacks. Lt. Gen. Yasuji Okamura, commanding the 11th Army, recognized this clearly. In a December 1939 report, he argued that diplomacy and small offensives were futile and urged a large-scale operation backed by substantial reinforcements. His superiors, however, were preoccupied with funding the broader military buildup and could offer no extra men. The post-Wuhan "defensiveization" of operations was largely a cost-saving measure to support that expansion. Japanese ground strength in China, which peaked near 850,000 after Wuhan, had already dropped by about 50,000. Full-strength regular or Class A divisions numbered roughly 22,000 men (four regiments), while newer garrison divisions had only about 15,000 (three regiments), and independent mixed brigades just 6,000. Okamura's proposal was sensible but politically impossible; high command was even contemplating slashing China troop levels to 400,000. The Chinese Winter Offensive of December 1939, together with counterattacks at Nanning and Kunlun Pass, inflicted serious losses and exposed the limited damage done to Chinese forces in 1939 operations. The recapture of Wuyuan in March 1940 signaled the start of a new phase. Shortly afterward, intensified Chinese guerrilla raids deep into Japanese rear areas prompted large Japanese "mop-up" operations in southern Shanxi, central Hubei, southern Jiangxi, and northern Hunan. In the Wuhan sector, repeated blows from the Winter Offensive heightened fears of Chinese forces in the Dahong and Tongbai Mountains, which threatened control over the vital Jianghan Plains rice-producing region. In mid-April 1940, the Japanese abandoned outposts at Macheng (eastern Hubei), Fengxin, and Jing'an (northern Jiangxi), withdrew elements of the 6th Division (northern Hunan), 40th Division (northern Jiangxi), and the 3rd, 13th, and 39th Divisions (Hubei), and concentrated them around Zhongxiang, Suixian, and Xinyang for a maximum-effort push. These setbacks finally forced Tokyo to abandon deep troop reductions in China and approve reinforcements of two regular divisions for a major 1940 offensive. The revised end-1940 target became 740,000 troops in China. In spring 1940, the 11th Army—backed fully by Imperial General Headquarters and the China Expeditionary Army—began detailed preparations for a large-scale assault on China's Fifth War Zone. On February 25, 1940, the 11th Army issued its "Guiding Strategy for the Campaign." The operational goal was to defeat the main force of China's Fifth War Zone along both banks of the Han River before the rainy season, inflict further heavy losses on Chiang Kai-shek's army through decisive victory, and thereby advance Japan's overall political and strategic position vis-à-vis China. The guiding principle called for the quickest possible preparations, with the offensive to begin around early May: first destroy Chinese forces on the left (east) bank south of the Baihe River, then completely annihilate the core units on the right (west) bank near Yichang. On April 7, under the new commander Lt. Gen. Sonobe Kazuo (who replaced Okamura Yasuji), the 11th Army produced a more detailed plan. On April 10, Imperial General Headquarters Order No. 426 ("Continental Order") authorized the China Expeditionary Army to conduct operations in central and southern China during May–June, even beyond established boundaries, to fulfill current objectives. Japanese planners viewed the Fifth War Zone—roughly 50 divisions encircling Wuhan—with its main strength concentrated along the Han (Xiang) River in northwestern Hubei. Striking Yichang would deliver a severe blow to the zone. As the gateway to Sichuan, only 480 km from Chongqing, Yichang held immense strategic value: an inland port, Three Gorges logistics hub, and key base for air raids on Chongqing. Capturing it would directly threaten the Nationalist wartime capital and southwestern rear, advancing political leverage. Still, long-term occupation was not pre-decided; initial plans stressed inflicting maximum damage followed by withdrawal, in line with the post-Wuhan policy of avoiding permanent overextension. China, aware that holding the Jianghan Plain's rice-producing areas enabled sustained attrition against Japan, deployed guerrilla units to harass Japanese rear areas (increasing occupier losses) while tasking the River Defense Force to hold key front-line points: Jingmen, Shashi, and Yichang. To achieve these aims, the 11th Army committed as much as possible of its seven divisions and four brigades (88 battalions total). Core units included the 3rd Division (Maj. Gen. Yamakoshi Masataka; regiments 6, 18, 34, 68), 13th Division (Maj. Gen. Tanaka Shioichi; 58, 65, 104, 116), 39th Division (Maj. Gen. Murakami Keisaku; 231–233), elements of the 40th Division, detachments from the 33rd and 34th Divisions, and others. Reinforcements comprised the Ikeda Detachment (three battalions from 6th Division), Ishimoto Detachment (four–five from 40th), Ogawa Detachment (two from 34th), and Provisional Mixed Brigade 101. Supporting assets included the 6th Field Heavy Artillery Regiment, 7th and 13th Tank Regiments, 3rd Air Group, Navy 1st China Dispatch Fleet, and 2nd Combined Air Team. The China Expeditionary Army transferred seven battalions from the 15th and 22nd Divisions (13th Army, lower Yangtze). The main effort north of the river involved roughly 48–54 battalions, or 80,000–110,000 men, making the Zaoyi (Zaoyang–Yichang) Campaign the largest Japanese operation on the central front since Wuhan. Sonobe's staff structured the offensive in two phases. Phase One targeted the Fifth War Zone's main force around Zaoyang (east of the Han River) through converging pincer movements: right flank from Xinyang (reinforced 3rd Division), left flank from Zhongxiang (reinforced 13th Division), and central thrust by the reinforced 39th Division from Suixian. The plan exploited terrain—Dahong and Tongbai Mountains—for encirclement. After seizing Minggang (right flank) and advancing from Zhongxiang (left), the pincers would close on Zaoyang, with the center (along the Xianghua Highway from Suixian) drawing Chinese forces into the trap for envelopment. Diversionary attacks south of the Yangtze, propaganda hinting at limited scope, and planted false orders helped mask intentions. Japanese radio intelligence—intercepts and direction-finding of Chinese headquarters signals—provided critical advantages, especially in later stages. By March 1940, Chinese intelligence had already detected the 11th Army's intent to mount a major offensive from Xinyang and Wuhan into northwestern Hubei. On April 10, Chiang Kai-shek telegraphed Li Zongren and other Fifth War Zone commanders, urging immediate preparations for a preemptive strike against any push toward Shapingba and Yichang. He emphasized proactive flanking attacks on Japanese rear areas via Wusheng Pass and threats to the Pinghan Railway, while keeping main forces east of the Han River for decisive engagement once the enemy committed. Following Military Commission directives, the Fifth War Zone devised a plan that used part of its strength for forward advances and deep raids into Japanese rear areas to harass and divert. The bulk of forces would hold the rear, seizing chances for preemptive strikes and a decisive battle east of Zaoyang or south of Jingmen–Dangyang. Deployments included: the 33rd Army Group garrisoning the Xiang River; in the center, the 45th Corps (22nd Army Group) west of Luoyangdian–Suixian and the 84th Corps (11th Army Group) north of Suixian–south of Gaocheng; in southern Henan, the 30th Corps east of Tongbai and the 68th Corps north of Pingchangguan–Minggang; the 41st Corps in reserve near Xiangyang; the 29th Army Group (with part garrisoning north of Tongqiao Zhen–Sanyangtien) concentrated in the Dahong Mountains; and the 31st Army Group positioned between Queshan and Ye Hsien as the mobile force to strike invaders. River Defense Army commander Guo Chan controlled the 26th, 75th, and 94th Armies, the 128th Division, and the 6th and 7th Guerrilla Columns. Total Chinese strength approximated 350,000–380,000 men across roughly 50–54 divisions. To mask preparations and mislead, the Japanese conducted a late-April "mop-up" near Jiujiang, staged naval feints on Poyang and Dongting Lakes, and bombed key points in Hunan and Jiangxi, simulating an imminent Ninth War Zone operation. With forces assembled, the Japanese offensive began May 1, 1940, from Xinyang, Suixian, and Zhongxiang. The advance split into five routes: (1) Changtaiguan–Minggang–Biyang–Tanghe; (2) Xinyang–Tongbai; (3) Suixian–Zaoyang; (4) Suixian–Wujiadien; (5) Zhongxiang–Shuangkou. Employing flanking with central breakthrough, the reinforced 3rd Division (right flank, including Ishimoto Detachment from 40th Division with tanks and engineers) spearheaded from Xinyang toward Biyang, breaching the Chinese Second Army front on day one. By May 1, elements of the 3rd and 40th Divisions captured Minggang, Lion's Bridge, and Xiaolintien; on May 5 they took Biyang and Tongbai. The Chinese 31st Army Group (northeast of Biyang) linked with the 68th and 92nd Corps to hit Japanese flanks and rear. Leaving some forces west of Tongbai to press the enemy, the main 30th Corps struck Japanese flanks. After seizing Tanghe on May 7, the Japanese pushed south toward Zaoyang. On May 8–9, the 31st Army Group retook Tanghe and Xinye, pursuing vigorously. On May 8, the Japanese left flank (13th Division) attacked from Zhongxiang, breaking through the 33rd Army front the same day. On May 3, the Japanese 13th Division—supported by over 20 tanks, 40 aircraft, artillery, and cavalry—advanced north from Zhongxiang, capturing Changshoudian and Tianjiachi. It seized Fengyao and Changjiachi by May 6. Chinese 33rd Army Group forces used favorable terrain to intercept, while the 29th Army Group struck Japanese flanks and rear at Changjiachi and Wangjiadian, and the 41st Corps fought tenaciously to halt the advance. By May 7, Japanese spearheads reached Changjiachi on the Zaoyang–Xiangyang Highway, with elements entering Shuangkou; their rear cavalry took Xinye on May 8. Fifth War Zone commander Zhang Zizhong personally led attacks along Tianjiachi–Huanglongtang, supported by fierce 29th Army Group assaults on Japanese rear. The Japanese 39th Division and a 6th Division brigade delayed their assault on the Chinese 11th Army Group until May 4 from Suixian. After overrunning Gaocheng and Anchu on May 5, Chinese forces withdrew to Huantan–Tang Hsien–north of Gaocheng. As the 33rd Army Group faltered, part of the 11th Army Group reinforced it; the 175th Division held at Tang Hsien while the main body fell back toward Zaoyang. During the maneuver, Japanese tanks enveloped at Tang Hsien, cutting the Zaoyang–Xiangyang Highway and forcing bitter fighting by the 174th Division. To break out, Chinese abandoned Zaoyang, using the 173rd Division for rearguard resistance while the bulk shifted west of the Tang and Bai Rivers. Japanese captured Suiyangdian and Wujiadien on May 7, Zaoyang on May 8; the 173rd Division suffered heavy losses, including the death of its commander, Gen. Zhong Yi. On May 10, Japanese completed an encirclement east of Xiangdong along the Tang and Bai Rivers—but it collapsed as Chinese exterior forces outflanked both Japanese wings and compressed the center, trapping much of the Japanese in the Xiangdong Plains. The Chinese 2nd and 31st Army Groups plus 92nd Corps pressed south, 39th and 75th Corps east, and 33rd and 29th Army Groups north against the pocket. The 94th Corps advanced along the Han–Yichang Highway deep into Jingshan, Zaoshi, Yingcheng, and Yunmeng to sever Japanese rear communications. Meanwhile, the 7th Corps and eastern Hubei guerrillas seized Jigong Shan, Lijiachai, and Liulin station on the Beijing–Hankou Railway. The 92nd and 68th Corps retook Zaoyang, Tongbai, and Minggang, encircling four Japanese divisions in the Xiangdong Plains. By May 11, battered Japanese retreated eastward under pursuit, Chinese flanking and rear attacks leaving many dead on the field. The 31st Army Group recovered Zaoyang on May 16. Chinese reports claimed 45,000 Japanese casualties, plus capture of over 60 guns, 2,000+ horses, 70+ tanks, and 400+ trucks. The 33rd Army Group fought fiercely to intercept retreating columns, driving large Japanese remnants toward Nanguadian. Tragically, on May 16 noon, Gen. Zhang Zizhong—personally commanding his Guard Battalion and main 74th Division—was killed in action. With pressure eased on the Japanese left, they counterattacked and retook Zaoyang on May 17. Chinese forces withdrew to Xinye on the Tangbai River's west bank and north of the Tang River, regrouping for a renewed counteroffensive. The Military Commission anticipated a Japanese withdrawal to original lines, likely along the rain-impassable Xianghua Road. Exploiting the enemy's supply shortages, exhaustion, and retreat difficulties, it ordered Fifth War Zone units to encircle and annihilate Japanese forces near the battlefield, then pursue toward Yingcheng–Huayuan. The zone promptly launched a counteroffensive. By nightfall on May 8, Japanese pincers neared junction, having inflicted serious damage on the Chinese 84th Army but achieved little else. Nonetheless, the 11th Army ordered frontline divisions to withdraw to the Tanghe–Baihe line after reaching it, preparatory to encircling Chinese forces west of the Han River. Chongqing issued general offensive orders at 8 PM and 11 PM that night. By then, six divisions of the 31st Army Group advanced south from Nanyang in the north, five from the 33rd Army Group pressed from the south, and five from the 45th and 94th Armies pursued in the southeast—nearly completing the Japanese encirclement. Intense combat erupted. On May 10, retreating Japanese first clashed with the advancing 33rd Army Group from the south. Seizing the moment, they ordered the 13th and 39th Divisions plus Ikeda Detachment south to smash it, with the 3rd Division covering the northern flank. Full-scale battle broke out on May 12: two Japanese divisions assaulted five Chinese divisions of the 33rd Army Group, plunging them into desperate fighting. Japanese radio intercepts—including telegrams between the Military Commission and Fifth War Zone, plus Zhang Zizhong's report to Chiang on his five divisions' movements—revealed exact positions and plans. Sonobe Kazuo concentrated the 13th and 39th Divisions to strike south along the Han's east bank against Zhang's army group, while ordering the 3rd Division (south of Xinye) back to Zaoyang to guard the rear. Direction-finding had long pinpointed the 33rd Army Group headquarters radio (call signs and bearings) about 10 km northeast of Yicheng. With air support, the Japanese encircled it. On the night of May 15, the 39th Division advanced from Fangjiaji and Nanying toward Nanguadian, completing tactical encirclement by dawn on May 16. Artillery-supported four-sided assaults followed. The defending 74th Division resisted fiercely with repeated counterattacks. Fighting raged into the afternoon, with the Special Service Battalion joining. Japanese attackers swelled to over 5,000, backed by concentrated artillery and 20+ aircraft for a final push. Zhang Zizhong, wounded multiple times, continued commanding calmly until a severe chest wound killed him heroically. The exhausted, isolated 74th Division and battalion suffered devastating losses. That day, the 13th Division also routed the main 33rd Army Group force, breaking the southern encirclement. Japanese then redeployed, concentrating around Zaoyang. In the north, 17 divisions (including six from the 31st Army Group) attacked the isolated Japanese 3rd Division from east, south, and north, severing its supply lines. With limited ammunition and no resupply, the division faced crisis; its 29th Brigade telegram pleaded: "Enemy fighting spirit extremely high... safe return very difficult; request battalion reinforcements." Yet southern Chinese forces remained undestroyed amid chaos. Japanese choices narrowed to independent 3rd Division retreat or holding for relief. They opted to lure pursuers: ordering the division southeast toward Zaoyang to draw Chinese into pursuit. From May 16–18, the 3rd Division fought a delaying retreat; relentless Chinese pursuit inflicted limited damage due to insufficient firepower, allowing escape. By evening May 18, it reached northeast of Zaoyang and prepared offensives. The 13th and 39th Divisions, after defeating the 33rd Army Group, also advanced north to the Zaoyang line. The 3rd Division's retreat shortened Japanese lines and hastened convergence. Unsuspecting Chinese pursued to Zaoyang. After a successful counterattack northeast of Yicheng, the 13th and 39th Divisions rejoined the 3rd Division there. On May 19 morning, three Japanese divisions attacked abreast, forcing decisive battle along the Tang River. Chinese divisions collapsed within hours; the 75th Army took heavy losses, others significant casualties. Fifth War Zone ordered hasty retreat. Japanese pursued vigorously. By May 21, the 3rd Division reached Dengxian, 13th east of Laohekou, 39th Fancheng. Early that day, the 39th Division—crossing the Baihe—met fierce west-bank fire, losing Regiment Commander Kanzaki Tetsujiro and over 300 men. That evening, the 11th Army halted pursuit, ending east-bank (Xiang River) fighting. The 20+ day operation east of the Han inflicted heavy Japanese losses, far exceeding the planned duration, leaving troops exhausted. After halting, units withdrew to Zaoyang vicinity for rest and reorganization rather than immediate return to base positions. Commanders debated proceeding to Yichang west of the Han: abandoning the plan would signal Phase One failure, eroding authority and imperial trust. Most argued troop fatigue and casualties should not deter continuation. Over 1,000 tons of supplies rushed forward via six motor companies. Following east-bank termination, Japanese consolidated for the next phase targeting Yichang. Reinforcements arrived: the 4th Division from Manchuria and 18th Independent Brigade from Wuning. The 4th Division assumed Shayang–Zhongxiang positions east of the Xiang River. The Japanese bombarded the west bank of the Han River for ninety minutes before forcing a crossing at Wangji north of Yicheng. That midnight, the 3rd Division also crossed southeast of Xiangyang. Both met little resistance and completed crossings before dawn. The 11th Army left the 40th Division at Dahongshan for rear-area mopping-up and assigned the Xiaochuan and Cangqiao Detachments to guard mobile supply depots. On May 31 night, the 3rd and 39th Divisions crossed the Xiang River at Yicheng and Oujiamiao. After seizing Xiangyang on June 1 night, the main force split into columns crossing westward. By June 3, Japanese captured Nanzhang and Yicheng. The Chinese 41st Corps fiercely counterattacked, retaking part of Xiangyang while its main body battled around Nanzhang; the 77th Corps also struck hard. On June 4, Chinese recovered Nanzhang, forcing Japanese retreat southward. Meanwhile, the 13th Division and elements of the 6th Division forced a crossing on the Han–Yichang Highway near Jiukou and Shayang to link with southern columns for a joint push. The Chinese River Defense Force shifted its main strength to key positions, using terrain to block southward advances. The 2nd and 31st Army Groups pursued south separately. Chinese abandoned Shayang on June 5; Japanese took Jingmen, Shilipu, and Shihujiao on June 6. The 77th Corps and river defense units resisted stubbornly from Jingmen to Jiangling. After retaking Yicheng, the 2nd Army Group continued pursuit. Japanese concentrated around Jingmen–Shilipu as Jiangling fell. On June 9 morning, Japanese launched joint air-ground assaults from Dongshi to Dangyang and Yuanan. By afternoon, penetrating the Chinese right flank forced a night withdrawal to Gulaobei–Shuanlianshi–Dangyang along the Zu River to Yuanan. June 10 saw Japanese capture Gulaobei and Dangyang, pushing Chinese to Yichang outskirts. After days of heavy fighting and prohibitive losses, Chinese abandoned Yichang on their own initiative. The 2nd and 31st Army Groups then reached Dangyang north of Jingmen. On June 16, they mounted a general offensive. By June 17, Chinese briefly retook Yichang; the 2nd Army Group linked with the 77th Corps against Dangyang, while the 31st Army Group severed Dangyang–Jingmen communications and assaulted Jingmen violently. South of the Yangtze, the 5th and 32nd Divisions crossed to hit Shayang and Shilipu. By June 18, Japanese main force held stubbornly from Dangyang to the Xiang River with superior equipment. Chinese, fighting on exterior lines, formed an encirclement from Jiangling–Yichang–Dangyang–Zhongxiang–Suixian–north of Xinyang while maintaining surveillance. Thus, the Zaoyi (Zaoyang–Yichang) Campaign ended. No prior decision existed on holding Yichang long-term. Per post-Wuhan Imperial General Headquarters policy, even extended operations aimed only to inflict severe blows and erode Chinese resistance, not expand occupation. On capture day, the 11th Army declared objectives achieved, ordering reorganization, destruction of Yichang military facilities, and dumping irremovable captured supplies into the Yangtze preparatory to withdrawal. At 10 PM June 15, formal orders withdrew to the Han's east bank: 3rd and 39th Divisions first to Dangyang–Jingmen to cover, then the 13th Division. The 13th began retreating from Yichang at midnight June 16, reaching Tumenya (10 km east) by 7 AM June 17. Chinese counterattacked along the route; the 18th Army pursued and retook Yichang morning of June 17. Japanese held Yichang only four days. Intense debate erupted between frontline commanders and Imperial General Headquarters over retaining Yichang. With Nazi Germany's Western Europe offensive underway—Paris fell June 12, the day Yichang was taken—global upheaval intensified Japanese urgency to resolve China swiftly and free resources for wider competition. Many in high command and China Expeditionary Army argued long-term occupation would threaten Chongqing more directly, aid political maneuvers, and hasten settlement, offering immense strategic value. This swayed the Emperor, who inquired at the June 15 Imperial Conference about securing it. Backed by imperial support, high command ordered temporary retention (one month) on June 16. By transmission through Expeditionary Army and 11th Army channels, the rearguard 13th Division had withdrawn 52 km. With 3rd Division cooperation, it reversed, broke Chinese resistance, and retook Yichang afternoon June 17. On July 1, to offset expanded 11th Army responsibilities, General Headquarters transferred the 4th Division from Kwantung Army (Jiamusi, Heilongjiang) to 11th Army control. July 13 orders confirmed long-term Yichang retention, redefining Wuhan-region operations to Anqing–Xinyang–Yichang–Yueyang–Nanchang. The 11th Army assigned: 13th Division to Yichang, 4th Division to Anlu, 18th Independent Mixed Brigade east/west of Dangyang; remaining units returned to original defenses. Post-recapture, Chinese continued counterattacks on Yichang and rear lines until ordered to halt: "To adapt to international changes, preserve National Army combat strength, and facilitate reorganization, Fifth War Zone cease attacks on Yichang immediately." A stalemate followed along lines encircling Yichang, Dangyang, Jiangling, Jingmen, Zhongxiang, Suixian, and Xinyang. To shield Chongqing and Sichuan, Nationalists re-established the Sixth War Zone (briefly created post-First Changsha, abolished April 1940), appointing Chen Cheng commander-in-chief with 33rd and 29th Army Groups, River Defense Army, and 18th Army covering western Hubei, western Hunan, eastern Sichuan. The Zaoyi campaign thus concluded. Japanese combat power again proved markedly superior. Official Japanese records (11th Army/China Expeditionary Army) reported 2,700 killed, ~7,800 wounded (total ~10,500; some phases ~1,403 killed/4,639 wounded). Chinese admitted heavy losses: 36,983 killed, 50,509 wounded, 23,000 missing (total >110,000 in some accounts). Wartime Nationalist claims inflated Japanese casualties to 45,000 killed/wounded with major captures (60+ guns, 70+ tanks, 400+ trucks), likely propagandistic; Japanese sources show far lower equipment losses. With 56 battalions deployed, Japanese suffered 12–15% combat casualties; Chinese (54 divisions, ~380,000 men) incurred 25–30% or higher—underscoring firepower/equipment disparity. Japan achieved tactical success by securing Yichang long-term (as a Chongqing bombing base) but failed to annihilate the main Chinese force or compel peace. Chinese resistance thwarted full encirclement and imposed attrition, albeit at crippling cost to the Fifth War Zone—severely weakened and never fully recovering until war's end. Japanese aims were realized to a significant, though not decisive, degree. The Fifth War Zone's operational plan was fundamentally sound. Chinese intelligence detected Japanese intentions early, accurately predicted the attack axis, and deployed accordingly. The plan included preemptive strikes at Wusheng Pass and the Guangshui section of the Pinghan Railway to harass Japanese rear areas, threaten Wuhan, gather reconnaissance, and disrupt enemy preparations. Though well conceived, these actions never materialized. In the first phase (Xiangdong operations), Chinese forces resisted while shifting the main body to outer lines, securing mobile flanking positions. This frustrated Japanese encirclement efforts in the Xiangdong Plains. Exploiting the enemy's retreat, China launched a timely counteroffensive that encircled the Japanese 3rd Division. Despite breakout support from over 100 aircraft and 200 tanks, the poorly equipped Chinese inflicted heavy casualties during the three-day siege, blunting the division's momentum. On the southern front, the 33rd Army Group's intercepting deployment was appropriate, but insufficient strength and compromised communications allowed the Japanese 13th and 39th Divisions to counterattack decisively, inflicting major losses and claiming the heroic death of Commander-in-Chief Zhang Zizhong—whose steadfast patriotism remains a lasting source of national pride. Overall, Chinese assessments and deployments in Phase One were largely correct. The battlefield showed China retained initiative and was not wholly dominated by Japanese plans. The core issue was overestimation of Chinese combat power amid severe shortages of heavy weapons. At least three corps suffered heavy attrition, yet Japanese captured only twenty-three mountain/field guns. Relying on manpower for brute force left Chinese units critically undergunned, enabling repeated encirclement attempts but preventing decisive destruction or severe damage to encircled enemies like the 3rd Division. Phase Two, by contrast, was entirely passive. The initial Japanese Han River crossings were largely feints, yet the west bank received scant attention in overall planning—leaving Yichang virtually undefended as main forces deployed east of the river. Post-Phase One, Japan reinforced the 11th Army with three infantry battalions and one mountain artillery battalion from the 13th Army (lower Yangtze), plus six motor transport companies rushing massive supplies forward. Chinese intelligence missed these moves, remaining complacent in expectation of Japanese withdrawal eastward. After regrouping, Japan abruptly pivoted west with rapid advances. The Military Commission and Fifth War Zone, caught unprepared, made frantic, chaotic adjustments that failed to mount effective defense. The loss of strategically vital Yichang was inevitable, complicating the resistance both militarily and psychologically. This stemmed directly from command misjudgment of Japanese strategic and operational aims. Had plans anticipated a westward thrust and retained strong reserves—or detected the 10-day regrouping window to readjust deployments—China could have retained greater initiative, inflicted more damage, and reduced its own losses.

Japan's 11th Army launched an offensive in Hubei to encircle Chinese forces in the Fifth War Zone and seize Yichang for bombing Chongqing. Chinese troops countered effectively, encircling Japanese divisions and inflicting heavy losses, though General Zhang Zizhong was killed in action. After intense fighting east of the Han River, Japanese crossed west, captured Yichang, briefly withdrew, then retook and held it long-term.

3.199 Fall and Rise of China: Battle of West Suiyuan

Last time we spoke about the battle of south Guangxi. In late 1939, amid the Sino-Japanese War stalemate, Japan aimed to sever China's vital supply lines from French Indochina by invading southern Guangxi. The 21st Army, including the 5th Division and Taiwan Mixed Brigade landed at Qinzhou Bay on November 15, capturing Nanning by November 24 after feinting at Beihai and overcoming scattered Chinese defenses under the 16th Army Group. Chinese forces, commanded by Bai Chongxi and reinforced by the elite 5th Army launched a counteroffensive in December. The brutal Battle of Kunlun Pass saw repeated assaults. However, Japanese counterattacks in January 1940, bolstered by the 18th Division and Konoye Brigade, recaptured Kunlun Pass and Binyang by February, inflicting over 10,000 Chinese losses and forcing retreats. A stalemate ensued until September 1940, when Japan pressured Indochina. Overextended Japanese forces withdrew south, allowing Chinese to recapture Nanning on October 30 and clear Guangxi by November 17. #199 The battle of West Suiyuan 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. Back in 1936, the Xi'an Incident had forced a fragile alliance between the Nationalists under Chiang Kai-shek and the Communists, forming a united front against Japan. This front extended to regional warlords like the Ma Clique, who controlled Ningxia, Gansu, and Qinghai. The Ma family, descendants of Muslim generals loyal to the Qing Dynasty, navigated complex loyalties but ultimately aligned with the Nationalist cause, driven by patriotism and self-preservation. The stakes in West Suiyuan were high. Control of the region meant access to the Suiyuan-Xinjiang Highway, a lifeline for Soviet aid to China. Japanese occupation could threaten the Shaanxi-Gansu-Ningxia Border Region, a Communist stronghold, and open paths to Lanzhou and beyond. The battles here, though overshadowed by larger theaters like Shanghai or Wuhan, demonstrated how peripheral fronts contributed to the national resistance. Over 70 years later, the sacrifices of more than 2,000 Ningxia soldiers remain a poignant reminder of the human cost of resistance, their anti-Japanese merits etched forever in the annals of Chinese history. The seeds of the Battle of West Suiyuan were sown in the turbulent years following the Xi'an Incident. This event in December 1936 led to the initial formation of a national united front against Japanese aggression. The Communist Party of China (CPC) mobilized masses in the Shaanxi-Gansu-Ningxia Border Region, strengthening anti-Japanese forces and exerting pressure on the Ma Clique. Chiang Kai-shek's Nationalist government also influenced the Mas, solidifying their resolve to resist Japan. The Ma Clique, a powerful Muslim warlord faction in Northwest China, was led by figures like Ma Hongkui (governor of Ningxia) and his cousin Ma Hongbin. They controlled a semi-autonomous region with a mix of Hui, Han, and Mongolian populations. Japan, seeking to exploit ethnic divisions, attempted to woo the Mas. Even after the July 7, 1937, outbreak of war, Japan persisted. On October 17, 1937, after occupying Baotou, the Japanese established the "Baotou Hui Muslim Branch" and appointed Jiang Wenhuan, a former Hui commander, to court Ma Hongkui. They sent envoys, including an imam from Northeast China, and even airdropped letters from "Manchukuo." In a dramatic move, Japanese commander Itagaki Seishiro flew to Alashan Banner to invite Ma Hongkui for talks. Ma sent Zhou Baihuang, who rebuffed Itagaki by invoking historical grievances: the Japanese role in the Eight-Nation Alliance's 1900 invasion, where Ma family members died at Zhengyang Gate. "The family feud remains unresolved, and the national humiliation is yet to be avenged; they are irreconcilable enemies," Zhou declared. Japan's plot to persuade surrender failed, leading to a major offensive against Suiyuan and Ningxia. Large numbers of troops reinforced Baotou, and bombings targeted Ningxia. In response, Ma Hongkui began building fortifications in places like Shizuishan and Dengkou. Starting in the winter of 1937, he constructed defense fortifications in the Shizuishan area in four phases. In the Shizuishan Weizha area, trenches several meters wide and deep were dug, covered with branches, straw, and loose soil for camouflage, to prevent the passage of Japanese armored vehicles and heavy weapons. Within a hundred li north of Dengkou and Sanshenggong, all major roads were cut off, and deep trenches were dug to destroy the Japanese army's access to Ningxia. The banks of the Yellow River ferry crossings in northern Ningxia and the Helan Mountain passages were all cut into steep cliffs. Important passageways were fortified with blocking positions and hidden artillery to repel invading Japanese troops. Among the various military commanders in Northwest China, Ma Hongbin possessed the strongest anti-Japanese spirit. Having joined the army at a young age, Ma Hongbin placed great emphasis on cultural learning and the cultivation of his personal character. Outside of military service, he was always seen with a book in hand, resembling a scholar. His long-term study fostered his upright character and patriotism. After the Japanese invasion of China, deeply moved by the nation's peril, he resolved to lead his troops to the battlefield to save the country from its crisis. In the spring of 1938, at the opening ceremony of an officer training course held in Wanghongbao, Yongning, Ma Hongbin addressed his subordinates from the podium: "Always remember that the nation comes first, the people come first, defend the land and country, and fulfill your duties. On the battlefield, you must be able to both attack and defend, and be prepared to live and die with the position, with the determination to fight to the end." The Ma forces were reorganized into the Nationalist structure. Ma Hongkui's 15th Route Army and Ma Hongbin's 35th Division (later expanded to the 81st Army) formed the 17th Army Group, with Ma Hongkui as Commander-in-Chief and Ma Hongbin as Deputy Commander-in-Chief and Commander of the 81st Army. The officer training of the 81st Army improved the anti-Japanese consciousness and combat quality of the entire army, preparing for the counterattack against the Japanese invasion. In May 1938, due to the weakened defenses of Suiyuan (at that time, the troops of Fu Zuoyi, the chairman of Suiyuan Province, had retreated to Shanxi), most of the area was occupied by Japanese and puppet troops. The Kuomintang Central Committee appointed Ma Hongbin as the commander of the Suiyuan West Defense Command. Ma Hongbin led his 81st Army and two cavalry brigades and one infantry brigade of Ma Hongkui's troops to Wuyuan (now Wuyuan County, Inner Mongolia Autonomous Region) to unify the command of the various anti-Japanese forces that had retreated into Suiyuan West. His mission was to prevent the Japanese army from advancing westward. After arriving in Wuyuan, Ma Hongbin convened a meeting of commanders from various forces to discuss the defense against the Japanese. The various armies in western Suiyuan were of different factions and not affiliated with each other, and most adopted a policy of seeking safety and avoiding danger in their defenses. Ma Hongbin deployed the main force of his 81st Army, the 35th Division, at key passes in the Wubu Langshan area northeast of Wuyuan to serve as the first line of defense, while deploying three brigades of Ma Hongkui's troops along the line from Wuyuan to Langshan as reinforcements. The terrain was challenging: vast deserts, mountains like Yinshan and Langshan, and the Yellow River's bends. Wubulangkou, a narrow pass between Erlang and Chashitai Mountains, was strategically vital. Defenses included anti-tank trenches and mines. These preparations reflected the Ningxia Army's blend of traditional cavalry tactics and modern training. The troops, many Hui Muslims, brought cultural cohesion and resilience, but faced equipment shortages—outdated mortars and rifles versus Japanese mechanization. In May 1938, Ma Hongbin arrived in Linhe (now part of Bayannur, Inner Mongolia) to establish his command post. After inspecting the situation of the friendly forces in the defense zone and designating the defense zone of his subordinate 81st Army, he ordered Ma Tengjiao, commander of the 35th Division, to lead four infantry regiments, namely the 103rd and 104th Brigades, to Suiyuan Western Defense Command to fight against the Japanese. Ma Hongbin established a command post in Linhe, where he and his son, Ma Dunjing, the chief of staff of the 81st Army, deployed their troops in areas such as Wuzhen and Siyitang. Ma Dunjing directed his troops to conduct exercises in the Wuzhen and Siyitang area, and invited Soviet military advisors to provide guidance, preparing for combat with an extremely serious attitude. To show his support for Ma Hongbin's leadership of the Suiyuan Western Defense Command, Ma Hongkui dispatched two cavalry brigades to Suiyuan Western Defense Command. The main reason why the Ma Clique army from Ningxia went to Suiyuan to fight against the Japanese was that the defense of Suiyuan was directly related to the safety of Ningxia. At the same time, after the Ma Clique army was incorporated into the anti-Japanese army, its primary task was to fight against the Japanese invaders and defend the country. In addition, the anti-Japanese enthusiasm of the people in the Northwest continued to rise. Under the impetus of the situation, it was inevitable that the Ningxia army would join the anti-Japanese war in Suiyuan. The initial engagement came in the late summer and early autumn of 1939, as Japanese troops, driving cars, armored vehicles, and tanks, advanced from Baotou towards the defenses of the 81st Army in western Suiyuan, attempting to annihilate the main force of the 81st Army. Ma Dunjing (the third son of Ma Hongbin), Chief of Staff of the 81st Army, personally commanded the operation at the front line in Wuda Town. The Japanese advanced to the defensive positions of the 35th Division and bombarded Ma's position with heavy artillery fire. The 35th Division returned fire with 82mm mortars. Because Ma's mortars were old-fashioned, they emitted smoke upon firing, revealing their positions. The Japanese immediately unleashed over 200 shells on the 35th Division's artillery positions, silencing them and rendering them incapable of retaliating. Taking advantage of this, the Japanese, under the powerful cover of artillery and machine gun fire, swarmed in by car, tank, and armored vehicle. The 35th Division held their ground, waiting for the Japanese troops to enter effective firing range and disembark from their vehicles. Suddenly, soldiers of the 1st Battalion of the 206th Regiment jumped out of their fortifications and charged into the enemy lines, engaging the Japanese in hand-to-hand combat. The Japanese were thrown into disarray, some killed before they could even disembark. Those who did disembark suffered heavy casualties, with the remaining soldiers turning back to their vehicles and fleeing in panic. Forced to retreat after suffering a decisive blow, the 35th Division captured two Japanese vehicles, over a hundred artillery shells, dozens of boxes of ammunition, as well as firearms and officer's swords. This marked the first victory in the Suiyuan-Western Anti-Japanese War. This victory boosted morale and public spirit. When the captured vehicles entered Wuyuan County, the people cheered enthusiastically, plastering the vehicles with various celebratory slogans. An elderly local artist even composed a song to celebrate the victory and sang it on the street: "Our old Western Army (referring to Ma Hongbin's 81st Army) is really good at fighting. We drove away the Japanese soldiers, captured cars and brought them into Wuyuan City, where the whole city celebrated and welcomed them. Relying on our old Western Army, we defeated the Japanese soldiers, and the people have peace." The campaign's defining battle occurred at Wubulangkou in early 1940, following the Chinese raid on Baotou in December 1939. In the autumn of 1939, the situation in Shanxi stabilized, and Fu Zuoyi, the chairman of Suiyuan Province who had retreated to Shanxi, led his troops back to western Suiyuan, establishing the Deputy Commander's Headquarters of the Eighth War Zone to unify command of military and political affairs in western Suiyuan and actively preparing for a counter-offensive. To coordinate with the nationwide winter offensive, Fu Zuoyi decided to attack Baotou, a key Japanese stronghold, to contain the Japanese forces in North China. The Battle of Baotou was spearheaded by the newly formed 31st Division of Fu Zuoyi's 35th Army, with the 35th Division of Ma Hongbin's 81st Army providing support. Under meticulous planning, on December 20th, Sun Lanfeng's newly formed 31st Division of Fu Zuoyi's army stormed into Baotou. The Japanese army, caught off guard, panicked and suffered over a thousand casualties, scattering in all directions, losing all their supplies within the city. Fu Zuoyi then directed his troops to withdraw to the rear of western Suiyuan, luring the enemy deeper into the territory for a later battle. The Battle of Baotou greatly angered the Japanese army. Therefore, more than 30,000 Japanese troops were mobilized from Zhangjiakou, Taiyuan, Datong, and other places, along with more than 1,500 military vehicles, armored vehicles, tanks, dozens of aircraft, and six divisions of puppet Mongolian troops, totaling more than 40,000 men. Under the command of Division Commander Kuroda, they launched a major offensive into western Suiyuan in early 1940, attempting to seize western and southern Inner Mongolia in one fell swoop. Facing the superior Japanese forces, the people and soldiers of western Suiyuan adopted a scorched-earth policy and mobile warfare to maneuver against the enemy. The specific deployment was as follows: the 7th Cavalry Division of Men Bingyue's troops blocked the Japanese troops in the Xishanzui and Maqidukou areas, and then turned to the right bank of the Yellow River to threaten the enemy's left flank; the 35th Division of Ma Hongbin's troops and the 1st Cavalry Brigade of Ma Hongkui's troops constructed positions in the Wubulangkou and Wuzhen areas, blocked the enemy, and then moved into Langshan to threaten the Japanese right flank; the 35th Army of Fu Zuoyi's troops assembled northwest of Wuyuan to launch mobile attacks on the enemy; other units chose favorable terrain to harass the exhausted enemy at any time; and the logistics personnel were transferred to the Dengkou and Shizuishan areas. Before Langshan Mountain, where the Yang family generals once fought against the Jin dynasty, a thousand-mile-long battlefield against the Japanese was set up. Wubulangkou is located in the western part of the Yinshan Mountains. Nestled between the eastern and western ends of the rugged and precipitous Erlang Mountain and Chashitai Mountain, it forms a strategically vital location. After Fu Zuoyi returned to western Suiyuan in 1939 to serve as deputy commander of the Eighth War Zone, the Ningxia army was placed under his command. At the end of December, Fu Zuoyi's troops stormed Baotou, inflicting over a thousand casualties on the Japanese. Okabe, commander of the Japanese Mengjiang Garrison, considered the defeat at Baotou a great humiliation and declared, "We must sweep through the Hetao region and completely annihilate Fu Zuoyi's army." To eliminate future troubles, the Japanese, "determined to decisively crush the enemy's base in the Hetao region with their main force," began in January 1940, mobilizing over 30,000 Japanese and puppet troops from Zhangjiakou, Datong, and other places, along with over a thousand vehicles, aircraft, artillery, and tanks. Under the command of Division Commander Kuroda Shigetoku, they launched a three-pronged, menacing invasion of western Suiyuan. On January 31, Kuroda led the main force of the Japanese central route, consisting of over 780 vehicles, armored vehicles, and tanks, and launched an attack at 4:30 PM on the positions of the 35th Division of the 81st Army in the area of Wubulangkou, Siyitang, and Wuzhen. Ubulangkou, where Ma Hongbin's 35th Division was stationed, is a transliteration of the Mongolian word "Ubulak," meaning "mouth of large and small springs." Located in the southern part of present-day Urad Middle Banner, it lies at the junction of Wuliangsutai, Delingshan Township, and Wengeng Sumu, a strategically important location nestled between two mountains. When the Battle of Ubulangkou began, Ma Hongbin was in Chongqing attending a high-level military conference convened by Chiang Kai-shek, and his troops were commanded by Ma Tengjiao, commander of the 35th Division. At approximately 8:00 AM on January 31, 1940, the Japanese army amassed its forces in the Zaoshulinzi desert area, directly north of Siyitang and directly east of Ubulangkou. Their vanguard first used three aircraft to circling and bombard the positions of Ma's 205th Regiment, followed by artillery bombardment. Under the cover of aircraft and artillery, Japanese tanks, armored vehicles, and hundreds of military vehicles carrying Japanese troops launched an attack on the Siyitang and Ubulangkou positions. Following Ma Hongbin's orders, a defensive trench, 3 meters wide and 3 meters deep, had been dug in front of the 81st Army's position, stretching approximately 10 kilometers from the foot of Wubulang Pass to the north bank of the Yellow River. A 50-meter-wide pit zone preceded the trench. The two sides fought fiercely until nightfall, suffering heavy casualties and remaining evenly matched. At the Siyitang position, Ding Liangyu, the company commander of the 1st Company, 1st Battalion, 205th Regiment, was wounded and died the following day; more than 30 platoon leaders, squad leaders, and soldiers were killed. Xue Wanyou, the battalion clerk, was hit by an artillery shell, his body torn apart and his head severed. Although the officers and soldiers of Ma's 35th Division suffered heavy casualties, they held their ground. Unable to break through, the Japanese used aircraft to continuously release poison gas with the wind at their backs. Although Ma's troops had prepared simple gas masks made of gauze wrapped in sawdust, the concentration of the gas was too high, causing many to experience headaches, chest tightness, and vomiting, greatly weakening their fighting capacity and making the situation increasingly critical. Around 10 PM, Division Commander Ma Tengjiao ordered Ma Jiangong, deputy battalion commander of the 2nd Battalion of the 206th Regiment, to lead two companies from Wulanaobao to reinforce the 208th Regiment via Siyitang. Ma Jiangong was killed by a grenade in the fierce fighting. The two companies fought desperately to break free from the enemy and finally joined up with the 208th Regiment. The enemy, realizing this, reinforced their forces and intensified their attack. At 11:30 PM, the 208th Regiment's position was breached, but the enemy dared not advance rashly. The battle resumed at dawn the next day, and the fighting at the Siyitang position remained extremely fierce. Ma Tengjiao ordered the 1st Battalion of the 206th Regiment to reinforce the Siyitang position. While traversing a seven- or eight-mile stretch of open land, the reinforcements were subjected to heavy artillery fire from the Japanese, suffering heavy casualties. However, the troops braved the artillery fire, bullets, and thick smoke, breaking through the enemy's fire blockade and reaching the position. The combined forces of the Wubulangkou and Siyitang positions continued to inflict powerful blows on the Japanese army. The 205th Regiment, holding the fortified Siyitang, engaged in bayonet fighting with the Japanese army. When their bayonets bent, the soldiers would grab the enemy and bite them, or detonate grenades to die alongside them. The troops had gone two days and two nights without food or water, and coupled with the bitter cold, they were exhausted and suffering heavy casualties. The battle was exceptionally fierce, tragic, and arduous. Ma Hongbin later recalled this battle, saying, "Even the world-famous battles of Taierzhuang and Changsha, where the National Revolutionary Army fought with such heroic spirit, were no more than this." In the early morning of February 1st, the Japanese army first bombarded the defensive positions at Wubulangkou and Siyitang with heavy artillery, and then used aircraft to dive-bomb the open area in front of Wubulangkou. Under the attack of enemy artillery and tanks combined with infantry, the 208th Regiment suffered heavy casualties, and the front-line positions at Wubulangkou were breached by the enemy. The 205th and 206th Regiments sent reinforcements, using bunkers and high ground fortifications to stubbornly resist the enemy, resulting in heavy casualties on both sides. Seeing that they could not capture the positions defended by the Ningxia army, the Japanese army released tear gas and sneezing gas. While attacking from the front, the Japanese army sent puppet Mongolian troops to flank and attack Wubulangkou from the rear of the mountain. Although the Ma troops resisted bravely, they were ultimately outnumbered, and their positions were successively breached by the enemy, forcing the remaining defenders to withdraw. In this battle, more than 1,000 officers and soldiers of the Ningxia Ma troops shed their blood in western Suiyuan, using their lives to block the enemy's advance. Ma's troops retreated, pursued by Japanese ground forces and strafed by aircraft, suffering over a thousand casualties and forced to retreat into the desert. They continued to fight the Japanese in the quicksand, killing another 200 enemy soldiers. After a grueling six-day, six-night march, the troops successfully returned to their Dengkou base for rest. Post-war statistics show that Ma's 35th Division originally had over 5,000 men; in the battle of Wubulangkou, over 1,000 were killed and 2,000 wounded, including 700 suffering from frostbite. This battle exemplified sacrificial defense, buying time for counteroffensives. Upon learning of the defeat of his troops in Chongqing, Ma Hongbin immediately flew back to Ningxia and rushed to Dengkou. After regrouping the troops and investigating officers who had failed in their command, he reorganized two regiments, replenished their equipment, and after a brief rest, led by Brigade Commander Ma Peiqing, returned to western Suiyuan. To cooperate with Fu Zuoyi's troops in continuing the fight against the Japanese invaders, the Ningxia army, mainly composed of the 35th Division, entered the Dala Banner area of Yimeng to fight the enemy. After occupying Wuyuan, the Japanese army believed that the Chinese army in western Suiyuan was in disarray and would be unable to recover its fighting capacity in a short time. Furthermore, due to its overextended battle lines and supply difficulties, the Japanese army had no spare troops to expand the war. Therefore, they centered their forces on Wuyuan, leaving a Japanese regiment and four divisions of puppet Mongolian troops, totaling over 15,000 men, to garrison the Hetao region, while the rest of their forces retreated eastward. After the main Japanese force withdrew, Fu Zuoyi decided to organize a campaign to recapture Wuyuan. In March 1940, he ordered his 35th Army to lead the attack on Wuyuan, while Ma's 81st Army moved from western Suiyuan to the Dalad Banner area on the south bank of the Yellow River in the Ordos League to construct fortifications and block Japanese reinforcements from Baotou. At midnight on March 20, Fu's 35th Army simultaneously launched attacks on Japanese strongholds in Wuyuan, Meilingmiao, and Xingongzhong. After two days of fierce fighting, our army finally recaptured Linhe and Wuyuan, killing Lieutenant General Mizukawa, the division commander of the Japanese army, and several thousand of his puppet troops. Upon hearing the news, the Japanese troops in Baotou crossed the Yellow River, attempting to outflank the 35th Army from the south. However, their westward advance was met with resistance from the positions of Ma's 81st Army. During the defensive battle, Ma's troops were bombarded by more than 30 Japanese artillery pieces. Due to outdated weaponry and lack of artillery counterattack, Ma's right flank was destroyed, allowing the enemy to encircle them from the rear. To avoid being outflanked, Ma's troops retreated north to the Shawo area to regroup. Ma Hongbin ordered each regiment to exploit the enemy's difficulty in vehicular movement in the desert, employing mobile warfare tactics, advancing when the enemy advanced and retreating when the enemy retreated, maintaining a distance of five or six li from the enemy, and choosing opportune moments to attack and exhaust them. Ma's troops also frequently formed assault teams to harass the enemy at night, keeping them constantly on edge. After maneuvering with the Japanese in the desert for several days using mobile warfare, Ma Hongbin's troops occupied a hilltop southwest of Xinminbao and laid an ambush. When the enemy approached, they unleashed a sudden barrage of fire, inflicting hundreds of casualties. This blow forced the Japanese army to abandon its southern reinforcement plan and retreat north across the Yellow River near Zhaojunfen. After the Japanese retreat, the 81st Army immediately launched an attack on the puppet Mongolian cavalry south of the Yellow River. After more than a month of battles, large and small, except for Chaidengtai, which was captured by Fu Zuoyi's troops, all other puppet strongholds were wiped out by Ma Hongbin's troops, and "the entire Damian Beach area in the northeast of the Ih Ju League was recovered." During the Qingming Festival in 1940, the 35th Division, returning to western Suiyuan, buried the officers and soldiers who died in the battle at Wubulangkou. With tears in their eyes, people buried the remains of 148 officers and soldiers at the Cemetery for Fallen Soldiers on the west side of Wubulangkou, and erected brick monuments in front of the graves according to the names on the surviving shoulder insignia of the fallen officers and soldiers' uniforms. Casualties on all sides were significant, reflecting the intensity of the fighting. For the Japanese, two brigades and the 72nd Cavalry Regiment took heavy hits, though official reports admitted only about 1,000 losses. Given that these units were sidelined from combat for an extended period afterward, the true figure was likely far higher. Battle reports from the 26th Division alone recorded over 3,000 casualties, nearly 20% of its strength,pushing the total Japanese toll, including other units, to between 4,000 and 5,000. Puppet forces fared even worse. The "Suiyuan-Western Autonomous Allied Army" proved utterly ineffective, collapsing almost immediately against the superior Ma Clique cavalry of the Nationalist 81st Army. While the puppet Mongolian cavalry had some combat capability, their reluctance to fight for the Japanese—often against their own kin, led to half-hearted engagements and quick retreats. Combined puppet casualties and prisoners numbered around 5,000 to 6,000, bringing the overall Japanese and puppet losses to 10,000–12,000 killed or wounded. The Chinese forces, vastly outmatched in equipment and relying on brave but undertrained local security units, endured heavy sacrifices. Domestic sources estimate their casualties at 15,000–20,000. This campaign marked the only major anti-Japanese engagement involving people from Ningxia, where over 10,000 Hui and Han fighters, under Ma Hongbin and Ma Hongkui, battled fiercely in what is now Linhe and Wuyuan in Inner Mongolia. Thousands perished, buried far from home, embodying the unyielding spirit of the Chinese nation. It stood as Northwest China's sole battlefield in the war, a point of pride for its people. Victory was hard-won, despite the Chinese having slightly more troops but far inferior weaponry. Success stemmed from the soldiers' bravery, tactical use of cavalry mobility, and crucially, the puppet Mongolians' unwillingness to fully commit. The campaign not only repelled the Japanese westward and southward advances, securing Northwest China's northern gateway and blocking incursions into Ningxia, Shaanxi, and Gansu, but also safeguarded key supply routes like the Suiyuan-Xinjiang Highway and connections to Lanzhou. This ensured a steady influx of Soviet aid, bolstering the national resistance and indirectly supporting efforts in Southwest China.

After a Chinese raid seized Baotou, Japan launched a major 1940 offensive with tens of thousands of troops, vehicles, armor, aircraft, and puppet Mongolian forces. Chinese defenders used scorched earth, fortifications at Wubulangkou, and mobile cavalry/desert tactics, ambushes, and night harassment. Fu Zuoyi later recaptured Wuyuan/Linhe. Casualties were heavy—Chinese estimates 15,000–20,000; Japanese/puppet losses possibly 10,000–12,000.

3.198 Fall and Rise of China: Battle of South Guangxi

Last time we spoke about the first battle of Changsha. Japanese forces under General Okamura Yasuji, including the 6th, 13th, and 33rd Divisions, launched a multi-pronged offensive, crossing the Xin Qiang River and capturing Yingtian amid brutal fighting. Chinese defenses, commanded by Xue Yue in the Ninth War Zone, employed gradual resistance strategies, with units like the 195th Division under Qin Yizhi holding key positions such as Bijia Mountain and Fulinpu, inflicting heavy losses. Battalion Commander Luo Wenlang recaptured Dongtang in a midnight assault, grieving his fallen brother amid Mid-Autumn moonlight. Chiang Kai-shek, from Chongqing, oversaw operations while hosting a festive banquet, buoyed by international support like U.S. loans. By October, Japanese advances stalled; Okamura ordered a retreat on October 2, exposed by a downed plane yielding critical documents. Chinese forces pursued, reclaiming lines by October 8, annihilating over half the invaders per Chiang's commendation. #198 The Battle of South Guangxi 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. In January 1939, the Japanese General Headquarters, responding to naval needs, ordered the 21st Corps to seize Hainan Island. The goal was to establish a base for air operations against southwestern China and to enforce blockade measures. Supported by the Japanese Navy, the Corps deployed the Taiwan Brigade, which landed at Haikou on February 10. After initial defeats, Chinese peace preservation units withdrew to the island's interior and conducted harassment operations. Japanese troops soon occupied northern counties including Qiongshan, Wenchang, Ding'an, Qionghai, and Chengmai, followed by the port of Yulin, which positioned them for southward advances toward Guangxi. This invasion was part of a broader strategy to disrupt Chinese supply lines and secure a foothold in southern China. Although Chinese resistance on Hainan ultimately failed to repel the invaders, it highlighted the resilience that would define regional fighting. After the costly Battle of Wuhan, the Sino-Japanese War reached a stalemate in central China, despite ongoing large-scale conflicts and Japanese strategic bombings that caused heavy casualties without breaking the deadlock. Politically, Japan's alignment with the Axis powers and the start of World War II in Western Europe led European nations to bolster ties with China. With major coastal ports under Japanese control, the Nationalist government's main overseas supply route became the Haiphong-Kunming railway in French Indochina, which transported four times more war materials in 1938 than in 1937, including heavy equipment purchased abroad. The Hainan occupation negatively impacted Japan's war efforts, though diplomatic pressure on Britain and France proved ineffective. Meanwhile, the Imperial Japanese Navy proposed a southward advance: invading from Nanning to Longzhou County in Guangxi by sea to establish an airfield for strategic bombing. An April 15, 1939, Navy Department assessment deemed large-scale inland army operations challenging, recommending instead that the army and navy collaborate to occupy Shantou—the largest trading port on the South China coast—before pushing into Guangxi to seize Nanning and sever China's vital Indochina supply line. In June, the Japanese General Staff's "Military Geography" emphasized that occupying Nanning would provide convenient transportation in all directions, reaching Guangdong, Hunan, Guizhou, and Yunnan. The Nanning-Lang Son road had become a major artery for Chiang Kai-shek's regime to connect with the southwest. To cut it off directly, Nanning must be captured first. Once occupied, heavy troops near Tokyo Bay would not be needed to achieve the operation's purpose. This idea gained considerable support both politically and tactically. The Army's northward policy had been defeated by the Soviet Union in the Battle of Khalkhin Gol in September 1939. Major General Tominaga Kyoji, the newly appointed head of the First Department of the General Staff, sought to avoid further embarrassments. Supporting the proposal involved transferring the 5th Division of the Kwantung Army, originally intended for Khalkhin Gol, to the south. This prevented front-line units from misjudging higher-ups' positions and allowed implementation without affecting existing troops. In September, the European war broke out. The Japanese General Headquarters ordered the 21st Army to capture the vicinity of Nanning, cut off the international passage between Guangxi and Vietnam, and obtain a base for air operations in southwest China. Japan aimed to completely sever China's most important supply route. According to Japanese intelligence, the French Indochina line accounted for 85% of China's foreign aid in late 1939, with 12,500 tons transported in September alone. On September 1, 1939, Germany attacked Poland; on September 3, Britain and France declared war on Germany, igniting World War II. Japan, eager to resolve the China issue and free up troops to seize Western colonies in Asia and the Pacific, stated through Prime Minister Nobuyuki Abe on September 4: "At the outbreak of the European war, the Empire will not intervene and has decided to focus on resolving the China Incident." In Nanjing, the China Expeditionary Army Headquarters was established, with General Nishio Hisazo as Commander-in-Chief and Lieutenant General Itagaki Seishiro as Chief of Staff, overseeing the North China Area Army, the 11th Army, the 13th Army, and the 21st Army. On September 23, the Japanese General Headquarters issued an order to prepare for a swift response to the China Incident. On October 16, "Continental Order No. 375" directed the Commander-in-Chief of the China Expeditionary Army to swiftly cut off enemy supply routes from Nanning to Longzhou with a portion of the navy. Also on October 16, "Continental Order No. 582," a central Army-Navy agreement, aimed to cut off enemy routes along the Nanning-Longzhou line and strengthen naval air operations against the Yunnan-Vietnam Railway and the Burma Road. The operation was scheduled for mid-November. On October 19, Nishio Juzo issued orders for the Guangxi operation, involving the 5th Division, Taiwan Mixed Brigade, supporting units, the 5th Fleet (renamed the 2nd Expeditionary Fleet in mid-November), and the 3rd Combined Naval Air Group. Total strength: about 30,000 men, over 70 warships, 2 aircraft carriers, and about 100 aircraft. Tominaga Kyoji announced: "This is the last battle of the China Incident." Politically, the Guangxi Army was a key pillar of the National Government after retreating to Sichuan. Attacking Guangxi could impact the Guangxi clique's stance on continuing the war. Cutting off the Nanning-Longzhou line would affect Vietnam-China transportation security and allow actions against French Indochina amid Europe's distractions. With tactical and political alignment, the plan was approved. In September 1939, the Chinese repelled the Japanese attack on Changsha. In October, the National Government held the Second Nanyue Military Conference in Hengshan, summarizing the First Changsha Campaign and deciding on a new offensive. On October 29, Chiang Kai-shek announced: "Our future strategic application and the mentality of officers and soldiers must be completely transformed. We must start to turn defense into offense, turn stillness into movement, and actively take offensive measures." On November 5, after the meeting, intelligence indicated Japan's intention to invade the south. U.S. and British agencies reported the Japanese fleet gathering in Tokyo Bay, signaling an imminent operation against Nanning. Chiang flew from Hengshan to Guilin to arrange defenses. At this time, coastal defense was guarded by the 16th Army Group under Xia Wei (transferred, with Cai Tingkai taking over), a Guangxi clique force comprising the 46th and 31st Armies. Bai Chongxi, director of the Guilin Headquarters, was in Chongqing for the Sixth Plenary Session of the Fifth National Congress of the Kuomintang, while Chief of Staff Lin Wei was in Rong County mourning Xia Wei's mother. The headquarters was essentially deserted. Zhang Fakui, commander of the Fourth War Zone, and Chief of Staff Wu Shiyuan were in Shaoguan, Guangdong. The three-tiered command structure—headquarters, war zone, army group—was practically non-existent. The Chinese forces north of the pass were commanded by Bai Chongxi's Guilin Headquarters, with Lin Wei as Chief of Staff; they included the Fourth War Zone under Zhang Fakui and the 16th Army Group under Xia Wei. They commanded: the 31st Army (Commander Wei Yunsong; 131st Division under He Weizhen; 135th Division under Su Zuxin; 188th Division under Wei Zhen); the 46th Army (Commander He Xuan; 170th Division under Li Xingshu; 175th Division under Feng Huang; New 19th Division under Huang Gu); and a portion of the 200th Division of the 5th Army (Commander Dai Anlan). Together with the 1st-4th Independent Infantry Regiments of the Guangxi Training Corps, total strength was approximately 60,000 men. After the Japanese landing, Bai Chongxi was stationed in Qianjiang, while the 16th Army Group headquarters in Xiawei was at Heishiyan near Binyang. In early November 1939, the Japanese 5th Fleet and the aircraft carrier Kaga escorted the 5th Division and the Taiwan Brigade to concentrate in Haikou. Japanese aircraft bombed important cities in Guangxi. At that time, the Chinese army defended the coast from Nanning to Qinzhou Bay and Fangcheng with part of the 16th Army Group of the Fourth War Zone. The 46th Army was responsible for the coastline of Fangcheng, Qinxian, Hepu, and Liankou, and the 31st Army for key points along the Xijiang River. On November 9, Japanese troops assembled at Sanya Bay on Hainan Island. Lieutenant General Ando Rikichi, commander of the 21st Army, personally commanded from Sanya. On the 13th, the fleet set sail. On the 14th, vanguard ships feinted at Beihai with over ten ships. A battalion of the 175th Division retaliated and was ordered to destroy Beihai, but Commander Chao Wei of the 524th Regiment believed no landing was intended, avoiding complete destruction. That night, Japanese ships turned toward Qinzhou. To safeguard the international communications link between Guangxi and Indochina, the Chinese Generalissimo's Headquarters in Guilin assigned defensive missions. The 46th Corps of the 16th Army Group was tasked with defending the coastline from Fangcheng to Qinzhou, Hepu, and Lianjiang. The 31st Corps was responsible for key positions along the Xi River. Defensive positions were prepared in advance, and communications infrastructure was sabotaged to facilitate gradual resistance, aiming to attrition Japanese forces before a decisive engagement along the Yong River. On November 15, under air and naval fire support, the Japanese 5th Division and Taiwan Brigade executed a forced landing on the west coast of Qinzhou Bay. Following intense resistance, the Chinese New 19th Division withdrew to Pancheng and Shangsi. After capturing Qinzhou, the Japanese 5th Division advanced north along the Yong-Qin Highway, while the Taiwan Brigade moved along Xiaodong–Baiji–Bujin Road. On November 17, the Japanese army captured Qinzhou and Fangcheng. The 5th Division immediately split into three routes along the Yongqin Highway, while the Taiwan Brigade advanced north along Xiaodong-Baekje-Pujin. On the 18th, they attacked Xiaodong, the headquarters of the New 19th Division. Division Commander Huang Gu fled alone in the face of battle. His troops were routed, and the Japanese continued northward. Meanwhile, bandits from the Shiwan Mountains formed numerous plainclothes teams to lead the Japanese advance, accelerating their northward movement. By November 21, they approached the south bank of the Yu River. On December 1, they occupied Gaofeng Pass. On December 4, they occupied Kunlun Pass and then adopted a defensive posture. On November 16, Chiang Kai-shek summoned Bai Chongxi in Chongqing, ordering him to return to Guilin immediately to command the battle, without attending the plenary session. Bai requested full command without intervention from Zhang Fakui, and that all armies obey the Headquarters directly. Chiang approved and transferred his elite Fifth Army and other units to Bai's command. Bai telegraphed Du Yuming to lead troops by train from Hengyang to southern Guilin and reinstated Xia Wei as commander of the 16th Army Group, with Cai Tingkai awaiting orders. The 16th Army Group assembled, and Deputy Commander-in-Chief Wei Yunsong arrived in Nanning on the 19th. Units rushed to block Japanese advances. Bai flew to Guilin on the 19th and Qianjiang on the 21st, establishing the command post. Thus, as Japanese arrived in Nanning, Chinese reinforcements like the 170th Division reached Yongning on the 22nd, two regiments of the 135th Division entered Nanning on the 23rd, and the 600th Regiment of the 200th Division arrived at Ertang on the afternoon of the 24th. Other armies assembled in Liuzhou and Binyang. On November 21, Japanese troops approached the south bank of the Yu River. Wu Zongjun, commander of the 405th Regiment of the 135th Division, arbitrarily ordered his regiments to abandon positions and retreat. Wei Yunsong ordered Su Zuxin to intercept, but Wu disobeyed. No troops defended Nanning's front lines. At dawn on the 24th, the 170th Division fought fiercely in Yongning. In the morning, the Japanese 21st Regiment crossed the river. By afternoon, Nanning had fallen. Over the next two days, they swept surrounding positions. On the morning of the 25th, the 600th Regiment of the 200th Division fought alone against Japanese regiments at Ertang. Under air cover, Japanese attacked, but Chinese resisted stubbornly. Regiment Commander Shao Yizhi and Adjutant Wu Qisheng were killed. Given the situation, Division Commanders Li Xingshu and Dai Anlan retreated to Gaofeng Pass after dusk. Though they failed to stop the advance, this was the fiercest resistance since the landing, lasting two days and nights. On November 25, Japanese attacked the 175th Division near Luwu from Xiaodong and the highway. The division moved to Nalong, assembling in villages there. The 175th attacked key points along the Yongqin Highway, including Datang, Naxiao, Dongya, Nabian, Xincheng, Xiaodong, Dadong, and Bancheng. On November 20, the 21st Army opened its headquarters in Qinzhou. On November 26, Ando Rikichi announced the formation of the Yongqin Corps under Imamura Hitoshi. Ando left for Guangzhou on the 27th. Starting on the 26th, Japanese attacked Gaofeng Pass with aircraft cover. Despite fierce resistance, Chinese lost Gaofeng Pass on December 1. On the 4th, Japanese occupied Kunlun Pass, then adjusted deployment. The two sides confronted each other along the Kunlun Pass mountainous boundary. According to statistics up to December 1, Japanese suffered 145 dead and 315 wounded; Chinese had 6,125 dead bodies and 664 prisoners (but Japanese casualties were underreported; the 41st Infantry Regiment received 727 replacements on January 19, likely matching killed and wounded sent back). Seized in Nanning: 300 tons lead, 200 tons coal, 500 bundles cotton, 321 tons cotton thread, 30 tons iron, 60 tons tin. On December 2, the Japanese 5th Cavalry Regiment and Morimoto Battalion were attacked by about 1,500 Chinese with four tanks at Batang. Japanese dispatched the 21st Brigade (Nakamura Detachment), repelling a mixed force of the 200th and 188th Divisions. Japanese occupied Kunlun Pass but left only a battalion to defend it, withdrawing the rest to Nanning. Bai Chongxi, director of the Guilin Headquarters and deputy chief of staff, proposed a counter-offensive plan, which was approved by Chiang Kai-shek. On November 24, when Japanese had just occupied Nanning, Bai Chongxi demanded an immediate counterattack while Japanese were unstable and weak. After failing to gain approval, Bai asked Du Yuming to submit a request. Du sent a telegram on December 1: "The enemy occupying Nanning is less than two divisions. They succeeded by exploiting our dispersed forces, but lack heavy weapons and supplies. Our army should gather superior forces and launch a counter-offensive quickly (before December 10) to defeat them and restore international transportation." Chiang decided on a counter-offensive on December 7. On the 8th, Bai conveyed the objective: "capturing Kunlun Pass and then recovering Nanning." By mid-December, assembly was complete. Chiang dispatched Chen Cheng and Li Jishen to supervise, and Zhang Fakui arrived in Qianjiang. In the early stages, Guangxi lacked heavy armored forces for counterattacking beyond Guangxi clique troops. The fall of Kunlun Pass prompted Chongqing to deploy the reorganized Fifth Army and its armored corps for a strong attack. The Fifth Army was the main force at Kunlun Pass, with the National Revolutionary Army providing cover while launching a full-scale counterattack in Nanning. To recapture Kunlun Pass and Nanning, Bai Chongxi dispatched approximately nine armies and twenty-seven divisions, totaling 300,000 troops: Xia Wei of the 16th Army Group, Ye Zhao of the 37th Army Group, Deng Longguang of the 35th Army Group, and Cai Tingkai of the 26th Army Group (31st, 5th, 64th, 46th, and 43rd Armies, etc.) to attack Kunlun Pass. The Japanese, with the Nakamura Brigade as main force and special forces, had strong fortifications. Xu Tingyao of the 38th Army Group, with Li Yannian of the 2nd Army, Gan Lichu of the 6th Army, Yao Chun of the 36th Army, and Fu Zhongfang of the 99th Army. The 5th Army, plus the 1st Honorary Division (Zheng Dongguo), New 22nd Division (Qiu Qingquan), and all armored, cavalry, artillery, and engineer regiments, arrived. The Japanese forces consisted of the 5th Division (Lieutenant General Hitoshi Imamura; 9th Brigade under Major General Genichiro Ogawa; 21st Brigade under Major General Masao Nakamura; Taiwan Mixed Brigade under Major General Sadashiro Shiota), Marine Corps (over 70 warships), and Air Force (100 aircraft), totaling about 30,000. Later reinforcements: Imperial Guard Division and a brigade from the 18th Division. Total about 100,000, but only 45,000 fought. After a traitor reported over 100,000 Nationalist troops north of Kunlun Pass, Imamura dismissed it as "impossible." Higher Japanese ranks hoped to instigate rebellion by the Guangxi clique. On December 10, Imamura issued a telegram "Letter to Generals Li and Bai," expressing respect and stating the attack on Nanning was to cut off Chiang's lines, hoping for Japan-China cooperation. If insisted, the Japanese garrison would win. Finally: "The more than 4,200 brave soldiers who died in Nanning have been buried in Zhongshan Park and solemnly offered sacrifices. Please rest assured." On December 15, Bai Chongxi took a decisive step in the escalating conflict by issuing the first counter-offensive order, setting the stage for a coordinated push against enemy positions. He organized the forces into three main route armies, with additional reserves held back for support. The Northern Route Army, under Xu Tingyao's command, focused its efforts on Kunlun Pass. The 5th Army led the direct assault there, while the 92nd Division from the 99th Army skirted around Lingliwei to strike at Qitang, effectively flanking the pass and adding pressure from the side. Meanwhile, the Western Route Army, led by Xia Wei, split into two columns to cover multiple fronts. The First Column, commanded by Zhou Zuhuang, targeted Gaofeng Pass in a bold advance. The Second Column, under Wei Yunsong, positioned itself at Suwei to block any reinforcements heading toward Nanning, cutting off potential enemy supply lines. On the eastern flank, Cai Tingkai's Eastern Route Army aimed to disrupt key logistics. The 46th Army moved against Luwu and Lingshan, intent on severing the vital Yongqin Highway. At the same time, the 66th Army joined the assault on Kunlun Pass before pushing onward to Gula and Gantang. To bolster these efforts, the remaining two divisions of the 99th Army were kept in reserve, ready to reinforce wherever needed. The very next day, on December 16, Du Yuming—now serving as army commander—gathered his officers for a critical conference within the 5th Army. There, they crafted a clever encirclement strategy dubbed "close the gate and fight the tiger," designed to trap and overwhelm the opposition. The plan's core involved the 200th Division, led by Dai Anlan, and the 1st Honorary Division under Zheng Dongguo launching the primary attack on Kunlun Pass. Flanking from the right, Qiu Qingquan's New 22nd Division would seize Wutang and Liutang, then turn to intercept any incoming reinforcements. On the left wing, Peng Bisheng commanded two regiments in a daring bypass of Gantang and Chang'an, aiming to strike at Qitang and Batang and seal off the enemy's retreat routes. The enemy at Kunlun Pass was the Matsumoto Sozaburo Battalion of the 21st Brigade. Its 42nd and 21st Regiments were along Jiutang-Nanning. On December 16, Imamura ordered Major General Kawai Genshichi of the 9th Brigade to lead thousands in a surprise attack on Longzhou and Zhennan Pass, departing on the 17th. At 8 p.m. on December 17, the Battle of Kunlun Pass began. On December 18, Chinese forces began their attack and captured Kunlun Pass and Jiutang on the same day. On December 19, it captured Gaofeng Pass. On December 20, Gaofeng Pass, Jiutang, and Kunlun Pass fell into the hands of the Japanese army again. At dawn on December 18, the artillery of the 5th Army opened fire. After extension, the 200th and 1st Honorary Divisions attacked. Hundreds of Japanese planes bombed. By night, the 1st Honorary captured Fairy Mountain, Laomaoling, Wanfu Village, Luotang, and Hill 411; 200th captured Hills 653 and 600, taking Kunlun Pass. At noon on the 19th, massive Japanese air raid. Imamura dispatched the 21st Regiment under Colonel Miki Yoshinosuke, recapturing it. Positions were contested repeatedly. The New 22nd occupied Wutang and Liutang; Wutang recaptured by Japanese, but Liutang held, blocking reinforcements. When Imamura ordered Taiwan Mixed Brigade reinforcement, they were blocked at Liutang by Qiu Qingquan. Du Yuming ordered Zheng Dongguo to send Zheng Tingji's 3rd Regiment to encircle Jiutang from the right. They captured high ground west of Jiutang at night. On December 20, enemy at Kunlun Pass weakened, sending urgent reports. Imamura ordered Nakamura Masao with 42nd Regiment to reinforce, but blocked at Wutang for two days, reaching Qitang on the 22nd, blocked again. Nakamura was wounded on the 23rd morning. At 1:30 pm, Miki reported: "If the brigade cannot arrive before dusk, the front line will be difficult to secure." Imamura ordered Colonel Lin Yixiong's 1st Regiment and Colonel Watanabe Nobuyoshi's 2nd Regiment of the Taiwan Mixed Brigade to reinforce, but blocked by 175th Division on Yongqin Road. Watanabe's regiment blocked at Luwu by 524th Regiment (Chao Wei), and after three days, couldn't pass. Watanabe was killed, remnants fled to Qin County. On the 20th, Imamura ordered the 9th Brigade's 3rd Battalion of Ito's unit back in 105 vehicles to reinforce. The Japanese confirmed the attack and Imamura ordered Nakamura Detachment rescue. Over two weeks, encirclement and breakout battles occurred on the Nanning-Kunlun Pass highway. On the 18th, the 170th Division launched the Battle of Gaofeng Pass, capturing a hill on the 19th but ambushed that night. On the 20th, the pass fell, retreating to Gewei. Bai inspected but no improvement; failed to capture Gaofeng Pass or block reinforcements. Ito's unit on Yonglong Road intercepted by 131st at Xichangwei. On the 22nd, Imamura sent two companies from Nanning, intercepted by 188th near Suwei. Ito's battalion besieged in Xichangwei for three days, spared because 131st avoided close combat. Under air cover, both broke through to Nanning on the 26th. On November 21, Chiang was dissatisfied with Kunlun Pass progress, ordering: "If front-line troops and artillery fail to attack or complete tasks, they shall be punished for cowardice." By the 23rd, two divisions of 5th Army had over 2,000 casualties; Japanese over 1,000. Six days yielded no results, with reinforcements arriving. Du changed tactics to concentrate forces, tightening encirclement. On the 24th, Oikawa Detachment ordered back to Nanning, destroying captured materials and withdrawing from Longzhou and Zhennanguan. Bai learned some escaped, telegraphing Wei Yunsong: "If the second batch escapes, it affects the main force. The deputy commander-in-chief should be punished." Main force still escaped; local troops preserved strength, benefiting Japanese. On the main position, Zheng Tingji spotted Japanese officers meeting and ordered fire, inflicting heavy casualties, requiring airdropped officers. On the 25th, Second Regiment of First Division captured Luotang South Heights, annihilating over 200. From December 25, Fifth Army and 159th and 92nd Divisions occupied key high grounds. Fierce battle until December 31, capturing Kunlun Pass and Tianyin, killing Nakamura Masao, annihilating over 5,000. Following the intense clashes at Kunlun Pass, the battle's toll on the Japanese forces became starkly evident in the weeks that followed. On January 19, just a month after the fighting peaked, the Japanese rushed in 3,389 fresh replacements to replenish their battered 5th Division. This influx was distributed unevenly: 1,848 went to the 21st Infantry Regiment and 814 to the 42nd, figures that likely corresponded directly to the number of dead and seriously wounded who had been evacuated back home—though those with minor injuries weren't factored into these counts. The ferocity of the engagement was further underscored by the capture of numerous Japanese strongholds, where Chinese forces found that every defender had been killed, leaving no survivors behind. In many ways, this outcome represented a stunning annihilation for the Japanese, particularly the 21st Brigade, which was effectively wiped out. Key figures fell in the fray, including Brigade Commander Masao Nakamura, Acting Commander Sakata Genichi, Miki Yoshinosuke, along with various deputies and battalion commanders. The leadership losses were catastrophic: over 85% of officers above the squad leader level were killed. Japanese records themselves acknowledged more than 4,000 soldiers dead, painting a grim picture that their own war histories later described as "the darkest era for the army." On the Chinese side, the victory came at a heavy price, with over 10,000 casualties suffered, yet remarkably, the core officer corps remained largely intact, preserving command structure for future operations. Zooming out to the broader theater in December 1939, the Japanese 5th Division and the Taiwan Mixed Brigade found themselves holding the line against an overwhelming force of more than 150,000 Nationalist troops. At the same time, the Japanese 21st Army was shifting its focus to Guangdong Province in preparation for Operation Weng Ying, while the Oikawa Detachment—primarily composed of the 11th Infantry Regiment—pushed forward to Longzhou. They captured Zhennanguan on November 21, securing valuable stocks of fuel and arms in the process. However, these stretched deployments and insufficient troop numbers left the Japanese without adequate reserves when encirclement loomed at Kunlun Pass. Ultimately, they were forced to abandon their offensive plans in Guangdong, pulling back to consolidate defenses around Nanning. Meanwhile, from their base in Chongqing, Chinese commanders had meticulously planned the recapture, turning the tide through careful strategy and sheer determination. Shocked, Japanese dispatched Vice Chief of Staff Sawada Shigeru to Guangzhou. On December 29, 21st Army sent staff to Nanning. Failed to change 21st Brigade's defeat. Imamura planned personal charge for revenge on January 1, but Ando ordered holding Nanning for reinforcements: "The 21st Army is transferring powerful force to annihilate enemy. 5th Division secure Nanning and key locations." After capturing Kunlun Pass and annihilating two regiments of 21st Brigade, 5th Army thought to recapture Nanning. Remaining 21st Brigade and Taiwan regiments between Jiutang and Batang. At noon January 1, 1940, Oikawa's thousands arrived at Batang; Imamura ordered Oikawa replace killed Sakata. First battle on Hill 441. 1st Division held north side; Japanese south. On January 1, Japanese bombed and attacked; 1st Division reduced to hundred but held. At dawn 2nd, counterattack all day, no progress. On 3rd, Du mobilized 200th and part New 22nd; brutal fighting, heavy casualties. At nightfall, Japanese retreated to Jiutang. On 4th, Japanese abandoned Jiutang to Batang. New 22nd moved into Jiutang. 5th Army attacked Batang; by 12th, no progress. Exhausted with heavy casualties, 5th Army ordered to Silong for rest. Mission transferred to 36th Army. 5th Army withdrew. On January 7, Chiang flew to Guilin, visiting Qianjiang on 10th to discuss plans with Bai, Chen, Zhang, Xu, Lin. Bai proposed offensive with new armies to recapture Nanning. Chiang approved. On 11th, as Bai issued orders, Chiang overturned, changing to defensive. Japanese gained time for counter-offensive. To salvage defeat, Japanese transferred 18th Division and Konoye Brigade from Guangdong. Combined with existing, formed 22nd Corps under Seiichi Kuno, under South China Front Army commanded by Reikichi Ando, preparing counteroffensive. On January 25, a brigade from the Japanese 18th Division and elements of the 15th Division attacked frontally along Yongbin Road, while Konoye Brigade flanked toward Guizhou via Yongyong Road, in Binyang Campaign. Konoye crossed at Tingziwei, then Yongchun County, via Gantang, Luwei, Gula, Wuling to Binyang, cutting rear. Bai Chongxi rushed 175th Division of 46th Army north to tail Konoye. After reinforcements, 21st Army launched offensive to drive and encircle south of Binyang; accumulated supplies in Nanning. On January 22, 18th and Konoye reached attack points. 38th Army Group HQ in Binyang bombed, communications cut, independent combat. On January 28, Japanese launched offensive (Binyang Operation). On February 3, 41st Infantry of 5th Division occupied Kunlun Pass. On February 4, Ando reached captured Binyang. Nationalists lost Kunlun Pass, lines collapsed, many encircled. Battle ended with withdrawal; February 13, Japanese withdrew to Nanning, lines stalemated. In the wake of the Binyang clashes, the 18th Division was indeed shifted to Guangzhou. Japanese records from January 28 to February 13 painted a picture of their spoils: they claimed to have captured 19 tanks, 5 light armored vehicles, 30 automobiles, 20 field or mountain guns, 13 rapid-fire guns, and 41 mortars. Additionally, they reported counting 27,041 Chinese bodies on the battlefield and taking 1,167 prisoners. The Chinese forces, for their part, regrouped with their main strength positioned east of the Yongqin Highway, while some elements maneuvered west to harass Japanese rear lines and coordinate actions from the north bank. On February 21, 1940, Chiang arrived in Liuzhou, residing at Yangjiao Mountain. From February 22, he convened over 100 generals for a four-day Liuzhou Military Conference to review Guinan operations. Chiang demoted Bai Chongxi for poor supervision and Chen Cheng for poor guidance from first- to second-class generals. He also punished and rewarded other senior officers. The 46th Army and 175th Division were commended for discipline. On February 26, Fourth War Zone Commander Zhang Fakui announced: "No need for counterattack on Nanning currently." The entire Guinan Campaign ended. The defeat embarrassed Chongqing; not only disrupted Guangxi-Vietnam traffic, but massive effort ended in rout. Pre-battle, Guilin Headquarters misjudged Japanese intentions; during, both Guangxi and Huangpu clique leaders showed poor performance, infuriating Chiang. Post-battle punishments were unprecedented in the war.

In November 1939, Japanese forces, including the 5th Division and Taiwan Brigade, landed at Qinzhou Bay, captured Nanning, and advanced to Kunlun Pass. Chinese troops, under Bai Chongxi and reinforced by the elite 5th Army, launched fierce counteroffensives, recapturing Kunlun Pass in December with heavy casualties.
