3.190 Fall and Rise of China: Zhukov Unleashes Tanks at Nomonhan

Last time we spoke about General Zhukov's arrival to the Nomohan incident. The Kwantung Army's inexperienced 23rd Division, under General Komatsubara, suffered heavy losses in failed offensives, including Colonel Yamagata's assault and the annihilation of Lieutenant Colonel Azuma's detachment, resulting in around 500 Japanese casualties. Tensions within the Japanese command intensified as Kwantung defied Tokyo's restraint, issuing aggressive orders like 1488 and launching a June 27 air raid on Soviet bases, destroying dozens of aircraft and securing temporary air superiority. This provoked Moscow's fury and rebukes from Emperor Hirohito. On June 1, Georgy Zhukov, a rising Red Army tactician and tank expert, was summoned from Minsk. Arriving June 5, he assessed the 57th Corps as inadequate, relieved Commander Feklenko, and took charge of the redesignated 1st Army Group. Reinforcements included mechanized brigades, tanks, and aircraft. Japanese intelligence misread Soviet supply convoys as retreats, underestimating Zhukov's 12,500 troops against their 15,000. By July, both sides poised for a massive clash, fueled by miscalculations and gekokujo defiance. #190 Zhukov Unleashes Tanks at Nomohan Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

At 4:00 a.m. on July 1, 15,000 heavily laden Japanese troops began marching to their final assembly and jump-off points. The sun rose at 4:00 a.m. and set at 9:00 p.m. that day, but the Japanese advance went undetected by Soviet/MPR commanders, partly because the June 27 air raid had temporarily cleared Soviet reconnaissance from the skies. On the night of July 1, Komatsubara launched the first phase. The 23rd Division, with the Yasuoka Detachment, converged on Fui Heights, east of the Halha River, about eleven miles north of its confluence with the Holsten. The term "heights" is misleading here; a Japanese infantry colonel described Fui as a "raised pancake" roughly one to one-and-a-half miles across, about thirty to forty feet higher than the surrounding terrain. For reasons not fully explained, the small Soviet force stationed on the heights was withdrawn during the day on July 1, and that night Fui Heights was occupied by Komatsubara's forces almost unopposed. This caused little stir at Zhukov's headquarters. Komatsubara bided his time on July 2. On the night of July 2–3, the Japanese achieved a brilliant tactical success. A battalion of the 71st Infantry Regiment silently crossed the Halha River on a moonless night and landed unopposed on the west bank opposite Fui Heights. Recent rains had swollen the river to 100–150 yards wide and six feet deep, making crossing difficult for men, horses, or vehicles. Combat engineers swiftly laid a pontoon bridge, completing it by 6:30 a.m. on July 3. The main body of Komatsubara's 71st and 72nd Infantry Regiments (23rd Division) and the 26th Regiment (7th Division) began a slow, arduous crossing. The pontoon bridge, less than eight feet wide, was a bottleneck, allowing only one truck at a time. The attackers could not cross with armored vehicles, but they did bring across their regimental artillery, 18 x 37-mm antitank guns, 12 x 75-mm mountain guns, 8 x 75-mm field guns, and 4 x 120-mm howitzers, disassembled, packed on pack animals, and reassembled on the west bank. The crossing took the entire day, and the Japanese were fortunate to go without interception. The Halha crossing was commanded personally by General Komatsubara and was supported by a small Kwantung Army contingent, including General Yano (deputy chief of staff), Colonel Hattori, and Major Tsuji from the Operations Section. Despite the big air raid having alerted Zhukov, the initial Japanese moves from July 1–3 achieved complete tactical surprise, aided by Tsuji's bold plan. The first indication of the major offensive came when General Yasuoka's tanks attacked predawn on July 3. Yasuoka suspected Soviet troops south of him attempting to retreat across the Halha to the west bank, and he ordered his tanks to attack immediately, with infantry not yet in position. The night's low clouds, no moon, and low visibility—along with a passing thunderstorm lighting the sky—made the scene dramatic. Seventy Japanese tanks roared forward, supported by infantry and artillery, and the Soviet 149th Infantry Regiment found itself overwhelmed. Zhukov, hearing of Yasuoka's assault but unaware that Komatsubara had crossed the Halha, ordered his armor to move northeast to Bain Tsagan to confront the initiative. There, Soviet armor clashed with Japanese forces in a chaotic, largely uncoordinated engagement. The Soviet counterattacks, supported by heavy artillery, halted much of the Japanese momentum, and by late afternoon Japanese infantry had to dig in west of the Halha. The crossing had been accomplished without Soviet reconnaissance detecting it in time, but Zhukov's counterattacks, the limits of Japanese armored mobility across the pontoon, and the heat and exhaustion of the troops constrained the Japanese effort. By the afternoon of July 3, Zhukov's forces were pressing hard, and the Japanese momentum began to stall. Yasuoka's tanks, supported by a lack of infantry and the fatigue and losses suffered by the infantry, could not close the gap to link with Komatsubara's forces. The Type 89 tanks, designed for infantry support, were ill-suited to penetrating Soviet armor, especially when faced with BT-5/BT-7 tanks and strong anti-tank guns. The Type 95 light tanks were faster but lightly armored, and suffered heavily from Soviet fire and air attacks. Infantry on the western bank struggled to catch up with tanks, shot through by Soviet artillery and armor, while the 64th Regiment could not keep pace with the tanks due to the infantry's lack of motorized transport. By late afternoon, Yasuoka's advance stalled far short of the river junction and the Soviet bridge. The infantry dug in to withstand Soviet bombardment, and the Japanese tank regiments withdrew to their jump-off points by nightfall. The Japanese suffered heavy losses in tanks, though some were recovered and repaired; by July 9, KwAHQ decided to withdraw its two tank regiments from the theater. Armor would play no further role in the Nomonhan conflict. The Soviets, by contrast, sustained heavier tank losses but began to replenish with new models. The July offensive, for Kwantung Army, proved a failure. Part of the failure stemmed from a difficult blend of terrain and logistics. Unusually heavy rains in late June had transformed the dirt roads between Hailar and Nomonhan into a mud-filled quagmire. Japanese truck transport, already limited, was so hampered by these conditions that combat effectiveness suffered significantly. Colonel Yamagata's 64th Infantry Regiment, proceeding on foot, could not keep pace with or support General Yasuoka's tanks on July 3–4. Komatsubara's infantry on the west bank of the Halha ran short of ammunition, food, and water. As in the May 28 battle, the main cause of the Kwantung Army's July offensive failure was wholly inadequate military intelligence. Once again, the enemy's strength had been seriously underestimated. Moreover, a troubling realization was dawning at KwAHQ and in the field: the intelligence error was not merely quantitative but qualitative. The Soviets were not only more numerous but also far more potent than anticipated. The attacking Japanese forces initially held a slight numerical edge and enjoyed tactical surprise, but the Red Army fought tenaciously, and the weight of Soviet firepower proved decisive. Japan, hampered by a relative lack of raw materials and industrial capacity, could not match the great powers in the quantitative production of military materiel. Consequently, Japanese military leaders traditionally emphasized the spiritual superiority of Japan's armed forces in doctrine and training, often underestimating the importance of material factors, including firepower. This was especially true of the army that had carried the tactic of the massed bayonet charge into World War II. This "spiritual" combat doctrine arose from necessity; admitting material superiority would have implied defeat. Japan's earlier victories in the Sino-Japanese War, Russo-Japanese War, the Manchurian incident, and the China War, along with legendary medieval victories over the Mongol hordes, seemed to confirm the transcendent importance of fighting spirit. Only within such a doctrine could the Imperial Japanese Army muster inner strength and confidence to face formidable enemies. This was especially evident against Soviet Russia, whose vast geography, population, and resources loomed large. Yet what of its spirit? The Japanese military dismissed Bolshevism as a base, materialist philosophy utterly lacking spiritual power. Consequently, the Red Army was presumed to have low morale and weak fighting effectiveness. Stalin's purges only reinforced this belief. Kwantung Army's recent experiences at Nomonhan undermined this outlook. Among ordinary soldiers and officers alike, from the 23rd Division Staff to KwAHQ—grim questions formed: Had Soviet materiel and firepower proven superior to Japanese fighting spirit? If not, did the enemy possess a fighting spirit comparable to their own? To some in Kwantung Army, these questions were grotesque and almost unthinkable. To others, the implications were too painful to face. Perhaps May and July's combat results were an aberration caused by the 23rd Division's inexperience. Nevertheless, a belief took hold at KwAHQ that this situation required radical rectification. Zhukov's 1st Army Headquarters, evaluating recent events, was not immune to self-criticism and concern for the future. The enemy's success in transporting nearly 10,000 men across the Halha without detection—despite heightened Soviet alert after the June 27 air raid—revealed a level of carelessness and lack of foresight at Zhukov's level. Zhukov, however, did not fully capitalize on Komatsubara's precarious position on July 4–5. Conversely, Zhukov and his troops reacted calmly in the crisis's early hours. Although surprised and outnumbered, Zhukov immediately recognized that "our trump cards were the armored detachments, and we decided to use them immediately." He acted decisively, and the rapid deployment of armor proved pivotal. Some criticized the uncoordinated and clumsy Soviet assault on Komatsubara's infantry on July 3, but the Japanese were only a few hours' march from the river junction and the Soviet bridge. By hurling tanks at Komatsubara's advance with insufficient infantry support, Mikhail Yakovlev (11th Tank Brigade) and A. L. Lesovoi (7th Mechanized Brigade) incurred heavy losses. Nonetheless, they halted the Japanese southward advance, forcing Komatsubara onto the defensive, from which he never regained momentum. Zhukov did not flinch from heavy casualties to achieve his objectives. He later told General Dwight D. Eisenhower that if the enemy faced a minefield, their infantry attacked as if it did not exist, treating personnel mine losses as equal to those that would have occurred if the Germans defended the area with strong troops rather than minefields. Zhukov admitted losing 120 tanks and armored cars that day—a high price, but necessary to avert defeat. Years later, Zhukov defended his Nomonhan tactics, arguing he knew his armor would suffer heavy losses, but that was the only way to prevent the Japanese from seizing the bridge at the river confluence. Had Komatsubara's forces advanced unchecked for another two or three hours, they might have fought through to the Soviet bridge and linked with the Yasuoka detachment, endangering Zhukov's forces. Zhukov credited Yakovlev, Lesovoi, and their men with stabilizing the crisis through timely and self-sacrificing counterattacks. The armored car battalion of the 8th MPR Cavalry Division also distinguished itself in this action. Zhukov and his tankmen learned valuable lessons in those two days of brutal combat. A key takeaway was the successful use of large tank formations as an independent primary attack force, contrary to then-orthodox doctrine, which saw armor mainly as infantry support and favored integrating armor into every infantry regiment rather than maintaining large, autonomous armored units. The German blitzkrieg demonstrations in Poland and Western Europe soon followed, but, until then, few major armies had absorbed the tank-warfare theories championed by Basil Liddell-Hart and Charles de Gaulle. The Soviet high command's leading proponent of large-scale tank warfare had been Marshal Mikhail Tukhachevsky. His execution in 1937 erased those ideas, and the Red Army subsequently disbanded armored divisions and dispersed tanks among infantry, misapplying battlefield lessons from the Spanish Civil War. Yet Zhukov was learning a different lesson on a different battlefield. The open terrain of eastern Mongolia favored tanks, and Zhukov was a rapid learner. The Russians also learned mundane, but crucial, lessons: Japanese infantry bravely clambering onto their vehicles taught Soviet tank crews to lock hatch lids from the inside. The BT-5 and BT-7 tanks were easily set aflame by primitive hand-thrown firebombs, and rear deck ventilation grills and exhaust manifolds were vulnerable and required shielding. Broadly, the battle suggested to future Red Army commander Zhukov that tank and motorized troops, coordinated with air power and mobile artillery, could decisively conduct rapid operations. Zhukov was not the first to envision combining mobile firepower with air and artillery, but he had rare opportunities to apply this formula in crucial tests. The July offensive confirmed to the Soviets that the Nomonhan incident was far from a border skirmish; it signaled intent for further aggression. Moscow's leadership, informed by Richard Sorge's Tokyo network, perceived Japan's renewed effort to draw Germany into an anti-Soviet alliance as a dangerous possibility. Stalin and Vyacheslav Molotov began indicating to Joachim von Ribbentrop and Adolf Hitler that Berlin's stance on the Soviet–Japanese conflict would influence Soviet-German rapprochement considerations. Meanwhile, Moscow decided to reinforce Zhukov. Tens of thousands of troops and machines were ordered to Mongolia, with imports from European Russia. Foreign diplomats traveling the Trans-Siberian Railway reported eastbound trains jammed with personnel and matériel. The buildup faced a major bottleneck at Borzya, the easternmost railhead in the MPR, about 400 miles from the Halha. To prevent a logistics choke, a massive truck transport operation was needed. Thousands of trucks, half-tracks, gun-towing tractors, and other vehicles were organized into a continuous eight-hundred-mile, five-day shuttle run. The Trans-Baikal Military District, under General Shtern, supervised the effort. East of the Halha, many Japanese officers still refused to accept a failure verdict for the July offensive. General Komatsubara did not return to Hailar, instead establishing a temporary divisional HQ at Kanchuerhmiao, where his staff grappled with overcoming Soviet firepower. They concluded that night combat—long a staple of Japanese infantry tactics—could offset Soviet advantages. On July 7 at 9:30 p.m., a thirty-minute Japanese artillery barrage preceded a nighttime assault by elements of the 64th and 72nd Regiments. The Soviet 149th Infantry Regiment and supporting Mongolian cavalry were surprised and forced to fall back toward the Halha before counterattacking. Reinforcements arrived on both sides, and in brutal close-quarters combat the Japanese gained a partial local advantage, but were eventually pushed back; Major I. M. Remizov of the 149th Regiment was killed and later posthumously named a Hero of the Soviet Union. Since late May, Soviet engineers had built at least seven bridges across the Halha and Holsten Rivers to support operations. By July 7–8, Japanese demolition teams destroyed two Soviet bridges. Komatsubara believed that destroying bridges could disrupt Soviet operations east of the Halha and help secure the border. Night attacks continued from July 8 to July 12 against the Soviet perimeter, with Japanese assaults constricting Zhukov's bridgehead while Soviet artillery and counterattacks relentlessly pressed. Casualties mounted on both sides. The Japanese suffered heavy losses but gained some positions; Soviet artillery, supported by motorized infantry and armor, gradually pushed back the attackers. The biggest problem for Japan remained Soviet artillery superiority and the lack of a commensurate counter-battery capability. Japanese infantry had to withdraw to higher ground at night to avoid daytime exposure to artillery and tanks. On the nights of July 11–12, Yamagata's 64th Regiment and elements of Colonel Sakai Mikio's 72nd Regiment attempted a major assault on the Soviet bridgehead. Despite taking heavy casualties, the Japanese managed to push defenders back to the river on occasion, but Soviet counterattacks, supported by tiresome artillery and armor, prevented a decisive breakthrough. Brigade Commander Yakovlev of the 11th Armored, who led several counterattacks, was killed and later honored as a Hero of the Soviet Union; his gun stands today as a monument at the battlefield. The July 11–12 action marked the high-water mark of the Kwantung Army's attempt to expel Soviet/MPR forces east of the Halha. Komatsubara eventually suspended the costly night attacks; by that night, the 64th Regiment had suffered roughly 80–90 killed and about three times that number wounded. The decision proved controversial, with some arguing that he had not realized how close his forces had come to seizing the bridge. Others argued that broader strategic considerations justified the pause. Throughout the Nomonhan fighting, Soviet artillery superiority, both quantitative and qualitative, became painfully evident. The Soviet guns exacted heavy tolls and repeatedly forced Japanese infantry to withdraw from exposed positions. The Japanese artillery, in contrast, could not match the Red Army's scale. By July 25, Kwantung Army ended its artillery attack, a humiliating setback. Tokyo and Hsinking recognized the futility of achieving a decisive military victory at Nomonhan and shifted toward seeking a diplomatic settlement, even if concessions to the Soviet Union and the MPR were necessary. Kwantung Army, however, opposed negotiations, fearing it would echo the "Changkufeng debacle" and be read by enemies as weakness. Tsuji lamented that Kwantung Army's insistence on framing the second phase as a tie—despite heavy Soviet losses, revealed a reluctance to concede any territory. Differences in outlook and policy between AGS and Kwantung Army—and the central army's inability to impose its will on Manchukuo's field forces—became clear. The military establishment buzzed with stories of gekokujo (the superiority of the superior) within Kwantung Army and its relations with the General Staff. To enforce compliance, AGS ordered General Isogai to Tokyo for briefings, and KwAHQ's leadership occasionally distanced itself from AGS. On July 20, Isogai arrived at General Staff Headquarters and was presented with "Essentials for Settlement of the Nomonhan Incident," a formal document outlining a step-by-step plan for Kwantung Army to maintain its defensive position east of the Halha while diplomatic negotiations proceeded. If negotiations failed, Kwantung Army would withdraw to the boundary claimed by the Soviet Union by winter. Isogai, the most restrained member of the Kwantung Army circle, argued against accepting the Essentials, insisting on preserving Kwantung Army's honor and rejecting a unilateral east-bank withdrawal. A tense exchange followed, but General Nakajima ended the dispute by noting that international boundaries cannot be determined by the army alone. Isogai pledged to report the General Staff's views to his commander and take the Essentials back to KwAHQ for study. Technically, the General Staff's Essentials were not orders; in practice, however, they were treated as such. Kwantung Army tended to view them as suggestions and retained discretion in implementation. AGS hoped the Essentials would mollify Kwantung Army's wounded pride. The August 4 decision to create a 6 Army within Kwantung Army, led by General Ogisu Rippei, further complicated the command structure. Komatsubara's 23rd Division and nearby units were attached to the 6 Army, which also took responsibility for defending west-central Manchukuo, including the Nomonhan area. The 6 Army existed largely on paper, essentially a small headquarters to insulate KwAHQ from battlefield realities. AGS sought a more accountable layer of command between KwAHQ and the combat zone, but General Ueda and KwAHQ resented the move and offered little cooperation. In the final weeks before the last battles, General Ogisu and his small staff had limited influence on Nomonhan. Meanwhile, the European crisis over German demands on Poland intensified, moving into a configuration highly favorable to the Soviet Union. By the first week of August, it became evident in the Kremlin that both Anglo-French powers and the Germans were vying to secure an alliance with Moscow. Stalin knew now that he would likely have a free hand in the coming war in the West. At the same time, Richard Sorge, the Soviet master spy in Tokyo, correctly reported that Japan's top political and military leaders sought to prevent the escalation of the Nomonhan incident into an all-out war. These developments gave the cautious Soviet dictator the confidence to commit the Red Army to large-scale combat operations in eastern Mongolia. In early August, Stalin ordered preparations for a major offensive to clear the Nomonhan area of the "Japanese samurai who had violated the territory of the friendly Outer Mongolian people." The buildup of Zhukov's 1st Army Group accelerated still further. Its July strength was augmented by the 57th and 82nd Infantry Divisions, the 6th Tank Brigade, the 212th Airborne Brigade, numerous smaller infantry, armor, and artillery units, and two Mongolian cavalry divisions. Soviet air power in the area was also greatly strengthened. When this buildup was completed by mid-August, Zhukov commanded an infantry force equivalent to four divisions, supported by two cavalry divisions, 216 artillery pieces, 498 armored vehicles, and 581 aircraft. To bring in the supplies necessary for this force to launch an offensive, General Shtern's Trans-Baikal Military District Headquarters amassed a fleet of more than 4,200 vehicles, which trucked in about 55,000 tons of materiel from the distant railway depot at Borzya. The Japanese intelligence network in Outer Mongolia was weak, a problem that went unremedied throughout the Nomonhan incident. This deficiency, coupled with the curtailment of Kwantung Army's transborder air operations, helps explain why the Japanese remained ignorant of the scope of Zhukov's buildup. They were aware that some reinforcements were flowing eastward across the Trans-Siberian Railway toward the MPR but had no idea of the volume. Then, at the end of July, Kwantung Army Intelligence intercepted part of a Soviet telegraph transmission indicating that preparations were under way for some offensive operation in the middle of August. This caused a stir at KwAHQ. Generals Ueda and Yano suspected that the enemy planned to strike across the Halha River. Ueda's initial reaction was to reinforce the 23rd Division at Nomonhan with the rest of the highly regarded 7th Division. However, the 7th Division was Kwantung Army's sole strategic reserve, and the Operations Section was reluctant to commit it to extreme western Manchukuo, fearing mobilization of Soviet forces in the Maritime Province and a possible attack in the east near Changkufeng. The Kwantung Army commander again ignored his own better judgment and accepted the Operations Section's recommendation. The main strength of the 7th Division remained at its base near Tsitsihar, but another infantry regiment, the 28th, was dispatched to the Nomonhan area, as was an infantry battalion from the Mukden Garrison. Earlier, in mid-July, Kwantung Army had sent Komatsubara 1,160 individual replacements to make up for casualties from earlier fighting. All these reinforcements combined, however, did little more than replace losses: as of July 25, 1,400 killed (including 200 officers) and 3,000 wounded. Kwantung Army directed Komatsubara to dig in, construct fortifications, and adopt a defensive posture. Colonel Numazaki, who commanded the 23rd Division's Engineer Regiment, was unhappy with the defensive line he was ordered to fortify and urged a slight pullback to more easily defensible terrain. Komatsubara, however, refused to retreat from ground his men had bled to take. He and his line officers still nourished hope of a revenge offensive. As a result, the Japanese defensive positions proved to be as weak as Numazaki feared. As Zhukov's 1st Army Group prepared to strike, the effective Japanese strength at Nomonhan was less than 1.5 divisions. Major Tsuji and his colleagues in the Operations Section had little confidence in Kwantung Army's own Intelligence Section, which is part of the reason why Tsuji frequently conducted his own reconnaissance missions. Up to this time it was gospel in the Japanese army that the maximum range for large-scale infantry operations was 125–175 miles from a railway; anything beyond 200 miles from a railway was considered logistically impossible. Since Kwantung Army had only 800 trucks available in all of Manchukuo in 1939, the massive Soviet logistical effort involving more than 4,200 trucks was almost unimaginable to the Japanese. Consequently, the Operations Staff believed it had made the correct defensive deployments if a Soviet attack were to occur, which it doubted. If the enemy did strike at Nomonhan, it was believed that it could not marshal enough strength in that remote region to threaten the reinforced 23rd Division. Furthermore, the 7th Division, based at Tsitsihar on a major rail line, could be transported to any trouble spot on the eastern or western frontier in a few days. KwAHQ advised Komatsubara to maintain a defensive posture and prepare to meet a possible enemy attack around August 14 or 15. At this time, Kwantung Army also maintained a secret organization codenamed Unit 731, officially the Epidemic Prevention and Water Purification Department of the Kwantung Army. Unit 731 specialized in biological and chemical warfare, with main facilities and laboratories in Harbin, including a notorious prison-laboratory complex. During the early August lull at Nomonhan, a detachment from Unit 731 infected the Halha River with bacteria of an acute cholera-like strain. There are no reports in Soviet or Japanese accounts that this attempted biological warfare had any effect. In the war's final days, Unit 731 was disbanded, Harbin facilities demolished, and most personnel fled to Japan—but not before they gassed the surviving 150 human subjects and burned their corpses. The unit's commander, Lieutenant General Ishii Shiro, kept his men secret and threatened retaliation against informers. Ishii and his senior colleagues escaped prosecution at the Tokyo War Crimes Trials by trading the results of their experiments to U.S. authorities in exchange for immunity. The Japanese 6th Army exerted some half-hearted effort to construct defensive fortifications, but scarcity of building materials, wood had to be trucked in from far away—helped explain the lack of enthusiasm. More importantly, Japanese doctrine despised static defense and favored offense, so Kwantung Army waited to see how events would unfold. West of the Halha, Zhukov accelerated preparations. Due to tight perimeter security, few Japanese deserters, and a near-absence of civilian presence, Soviet intelligence found it hard to glean depth on Japanese defensive positions. Combat intelligence could only reveal the frontline disposition and closest mortar and artillery emplacements. Aerial reconnaissance showed photographs, but Japanese camouflage and mock-ups limited their usefulness. The new commander of the 149th Mechanized Infantry Regiment personally directed infiltration and intelligence gathering, penetrating Japanese lines on several nights and returning crucial data: Komatsubara's northern and southern flanks were held by Manchukuoan cavalry, and mobile reserves were lacking. With this information, Zhukov crafted a plan of attack. The main Japanese strength was concentrated a few miles east of the Halha, on both banks of the Holsten River. Their infantry lacked mobility and armor, and their flanks were weak. Zhukov decided to split the 1st Army Group into three strike forces: the central force would deliver a frontal assault to pin the main Japanese strength, while the northern and southern forces, carrying the bulk of the armor, would turn the Japanese flanks and drive the enemy into a pocket to be destroyed by the three-pronged effort. The plan depended on tactical surprise and overwhelming force at the points of attack. The offensive was to begin in the latter part of August, pending final approval from Moscow. To ensure tactical surprise, Zhukov and his staff devised an elaborate program of concealment and deception, disinformation. Units and materiel arriving at Tamsag Bulak toward the Halha were moved only at night with lights out. Noting that the Japanese were tapping telephone lines and intercepting radio messages, 1st Army Headquarters sent a series of false messages in an easily decipherable code about defensive preparations and autumn-winter campaigning. Thousands of leaflets titled "What the Infantryman Should Know about Defense" were distributed among troops. About two weeks before the attack, the Soviets brought in sound equipment to simulate tank and aircraft engines and heavy construction noises, staging long, loud performances nightly. At first, the Japanese mistook the sounds for large-scale enemy activity and fired toward the sounds. After a few nights, they realized it was only sound effects, and tried to ignore the "serenade." On the eve of the attack, the actual concentration and staging sounds went largely unnoticed by the Japanese. On August 7–8, Zhukov conducted minor attacks to expand the Halha bridgehead to a depth of two to three miles. These attacks, contained relatively easily by Komatsubara's troops, reinforced Kwantung Army's false sense of confidence. The Japanese military attaché in Moscow misread Soviet press coverage. In early August, the attaché advised that unlike the Changkufeng incident a year earlier, Soviet press was largely ignoring the conflict, implying low morale and a favorable prognosis for the Red Army. Kwantung Army leaders seized on this as confirmation to refrain from any display of restraint or doubt, misplaced confidence. There were, however, portents of danger. Three weeks before the Soviet attack, Colonel Isomura Takesuki, head of Kwantung Army's Intelligence Section, warned of the vulnerability of the 23rd Division's flanks. Tsuji and colleagues dismissed this, and General Kasahara Yukio of AGS also went unheeded. The "desk jockey" General Staff officers commanded little respect at KwAHQ. Around August 10, General Hata Yuzaburo, Komatsubara's successor as chief of the Special Services Agency at Harbin, warned that enemy strength in the Mongolian salient was very great and seriously underestimated at KwAHQ. Yet no decisive action followed before Zhukov's attack. Kwantung Army's inaction and unpreparedness prior to the Soviet offensive appear to reflect faulty intelligence compounded by hubris. But a more nuanced explanation suggests a fatalistic wishful thinking rooted in the Japanese military culture—the belief that their spiritual strength would prevail, leading them to assume enemy strength was not as great as reported, or that victory was inevitable regardless of resources. Meanwhile, in the rational West, the Nazi war machine faced the Polish frontier as Adolf Hitler pressed Stalin for a nonaggression pact. The German-Soviet Nonaggression Pact would neutralize the threat of a two-front war for Germany and clear the way for Hitler's invasion of Poland. If the pact was a green light, it signaled in both directions: it would also neutralize the German threat to Russia and clear the way for Zhukov's offensive at Nomonhan. On August 18–19, Hitler pressed Stalin to receive Ribbentrop in Moscow to seal the pact. Thus, reassured in the West, Stalin dared to act boldly against Japan. Zhukov supervised final preparations for his attack. Zhukov held back forward deployments until the last minute. By August 18, he had only four infantry regiments, a machine gun brigade, and Mongolian cavalry east of the Halha. Operational security was extremely tight: a week before the attack, Soviet radio traffic in the area virtually ceased. Only Zhukov and a few key officers worked on the plan, aided by a single typist. Line officers and service chiefs received information on a need-to-know basis. The date for the attack was shared with unit commanders one to four days in advance, depending on seniority. Noncommissioned officers and ordinary soldiers learned of the offensive one day in advance and received specific orders three hours before the attack. Heavy rain grounded Japanese aerial reconnaissance from August 17 to midday on the 19th, but on August 19 Captain Oizumi Seisho in a Japanese scout plane observed the massing of Soviet forces near the west bank of the Halha. Enemy armor and troops were advancing toward the river in dispersed formations, with no new bridges but pontoon stocks spotted near the river. Oizumi sent a warning to a frontline unit and rushed back to report. The air group dispatched additional recon planes and discovered that the Japanese garrison on Fui Heights, near the northern end of Komatsubara's line, was being encircled by Soviet armor and mechanized infantry—observed by alarmed Japanese officers on and near the heights. These late discoveries on August 19 were not reported to KwAHQ and had no effect on the 6th Army and the 23rd Division's alertness on the eve of the storm. As is common in militaries, a fatal gap persisted between those gathering intelligence and those in a position to act on it. On the night of August 19–20, under cover of darkness, the bulk of the Soviet 1st Army Group crossed the Halha into the expanded Soviet enclave on the east bank.

By August, European diplomacy left Moscow confident in a foothold against Germany and Britain, while Sorge's intelligence indicated Japan aimed to avoid a full-blown war. Stalin ordered a major offensive to clear Nomonhan, fueling Zhukov's buildup in eastern Mongolia. Kwantung Army, hampered by limited logistics, weak intelligence, and defensive posture, faced mounting pressure.

3.189 Fall and Rise of China: General Zhukov Arrives at Nomonhan

Last time we spoke about the beginning of the Nomohan incident. On the fringes of Manchuria, the ghosts of Changkufeng lingered. It was August 1938 when Soviet and Japanese forces locked in a brutal standoff over a disputed hill, claiming thousands of lives before a fragile ceasefire redrew the lines. Japan, humiliated yet defiant, withdrew, but the Kwantung Army seethed with resentment. As winter thawed into 1939, tensions simmered along the Halha River, a serpentine boundary between Manchukuo and Mongolia. Major Tsuji Masanobu, a cunning tactician driven by gekokujo's fire, drafted Order 1488: a mandate empowering local commanders to annihilate intruders, even luring them across borders. Kwantung's leaders, bonded by past battles, endorsed it, ignoring Tokyo's cautions amid the grinding China War. By May, the spark ignited. Mongolian patrols crossed the river, clashing with Manchukuoan cavalry near Nomonhan's sandy hills. General Komatsubara, ever meticulous, unleashed forces to "destroy" them, bombing west-bank outposts and pursuing retreats. Soviets, bound by pact, rushed reinforcements, their tanks rumbling toward the fray. What began as skirmishes ballooned into an undeclared war. #189 General Zhukov Arrives at Nomohan 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. Though Kwantung Army prided itself as an elite arm of the Imperial Japanese Army, the 23rd Division, formed less than a year prior, was still raw and unseasoned, lacking the polish and spirit typical of its parent force. From General Michitaro Komatsubara downward, the staff suffered a collective dearth of combat experience. Intelligence officer Major Yoshiyasu Suzuki, a cavalryman, had no prior intel background. While senior regimental commanders were military academy veterans, most company and platoon leaders were fresh reservists or academy graduates with just one or two years under their belts. Upon arriving in Manchukuo in August 1938, the division found its Hailar base incomplete, housing only half its troops; the rest scattered across sites. Full assembly at Hailar occurred in November, but harsh winter weather curtailed large-scale drills. Commanders had scant time to build rapport. This inexperience, inadequate training, and poor cohesion would prove costly at Nomonhan. Japan's army held steady at 17 divisions from 1930 to 1937, but the escalating China conflict spurred seven new divisions in 1938 and nine in 1939. Resource strains from China left many under-equipped, with the 23rd, stationed in a presumed quiet sector, low on priorities. Unlike older "rectangular" divisions with four infantry regiments, the 23rd was a modern "triangular" setup featuring the 64th, 71st, and 72nd. Materiel gaps were glaring. The flat, open terrain screamed for tanks, yet the division relied on a truck-equipped transport regiment and a reconnaissance regiment with lightly armored "tankettes" armed only with machine guns. Mobility suffered: infantry marched the final 50 miles from Hailar to Nomonhan. Artillery was mostly horse-drawn, including 24 outdated Type 38 75-mm guns from 1907, the army's oldest, unique to this division. Each infantry regiment got four 37-mm rapid-fire guns and four 1908-era 75-mm mountain guns. The artillery regiment added 12 120-mm howitzers, all high-angle, short-range pieces ill-suited for flatlands or anti-tank roles. Antitank capabilities were dire: beyond rapid-fire guns, options boiled down to demolition charges and Molotov cocktails, demanding suicidal "human bullet" tactics in open terrain, a fatal flaw against armor. The division's saving grace lay in its soldiers, primarily from Kyushu, Japan's southernmost main island, long famed for hardy warriors. These men embodied resilience, bravery, loyalty, and honor, offsetting some training and gear deficits. Combat at Nomonhan ramped up gradually, with Japanese-Manchukuoan forces initially outnumbering Soviet-Mongolian foes. Soviets faced severe supply hurdles: their nearest rail at Borzya sat 400 miles west of the Halha River, requiring truck hauls over rough, exposed terrain prone to air strikes. Conversely, Hailar was 200 miles from Nomonhan, with the Handagai railhead just 50 miles away, linked by three dirt roads. These advantages, plus Europe's brewing Polish crisis, likely reassured Army General Staff and Kwantung Army Headquarters that Moscow would avoid escalation. Nonetheless, Komatsubara, with KwAHQ's nod, chose force to quash the Nomonhan flare-up. On May 20, Japanese scouts spotted a Soviet infantry battalion and armor near Tamsag Bulak. Komatsubara opted to "nip the incident in the bud," assembling a potent strike force under Colonel Takemitsu Yamagata of the 64th Infantry Regiment. The Yamagata detachment included the 3rd Battalion, roughly four companies, 800 men, a regimental gun company, three 75-mm mountain guns, four 37-mm rapid-fires, three truck companies, and Lieutenant Colonel Yaozo Azuma's reconnaissance group, 220 men, one tankette, two sedans, 12 trucks. Bolstered by 450 local Manchukuoan troops, the 2,000-strong unit was tasked with annihilating all enemy east of the Halha. The assault was set for May 22–23. No sooner had General Komatsubara finalized this plan than he received a message from KwAHQ: "In settling the affair Kwantung Army has definite plans, as follows: For the time being Manchukuoan Army troops will keep an eye on the Outer Mongolians operating near Nomonhan and will try to lure them onto Manchukuoan territory. Japanese forces at Hailar [23rd Division] will maintain surveillance over the situation. Upon verification of a border violation by the bulk of the Outer Mongolian forces, Kwantung Army will dispatch troops, contact the enemy, and annihilate him within friendly territory. According to this outlook it can be expected that enemy units will occupy border regions for a considerable period; but this is permissible from the overall strategic point of view". At this juncture, Kwantung Army Headquarters advocated tactical caution to secure a more conclusive outcome. Yet, General Michitaro Komatsubara had already issued orders for Colonel Takemitsu Yamagata's assault. Komatsubara radioed Hsinking that retracting would be "undignified," resenting KwAHQ's encroachment on his authority much as KwAHQ chafed at Army General Staff interference. Still, "out of deference to Kwantung Army's feelings," he delayed to May 27 to 28. Soviet air units from the 57th Corps conducted ineffective sorties over the Halha River from May 17 to 21. Novice pilots in outdated I 15 biplanes suffered heavily: at least 9, possibly up to 17, fighters and scouts downed. Defense Commissar Kliment Voroshilov halted air ops, aiding Japanese surprise. Yamagata massed at Kanchuerhmiao, 40 miles north of Nomonhan, sending patrols southward. Scouts spotted a bridge over the Halha near its Holsten junction, plus 2 enemy groups of ~200 each east of the Halha on either Holsten side and a small MPR outpost less than a mile west of Nomonhan. Yamagata aimed to trap and destroy these east of the river: Azuma's 220 man unit would drive south along the east bank to the bridge, blocking retreat. The 4 infantry companies and Manchukuoan troops, with artillery, would attack from the west toward enemy pockets, herding them riverward into Azuma's trap. Post destruction, mop up any west bank foes near the river clear MPR soil swiftly. This intricate plan suited early MPR foes but overlooked Soviet units spotted at Tamsag Bulak on May 20, a glaring oversight by Komatsubara and Yamagata. Predawn on May 28, Yamagata advanced from Kanchuerhmiao. Azuma detached southward to the bridge. Unbeknownst, it was guarded by Soviet infantry, engineers, armored cars, and a 76 mm self propelled artillery battery—not just MPR cavalry. Soviets detected Azuma pre dawn but missed Yamagata's main force; surprise was mutual. Soviet MPR core: Major A E Bykov's battalion roughly 1000 men with 3 motorized infantry companies, 16 BA 6 armored cars, 4 76 mm self propelled guns, engineers, and a 5 armored car recon platoon. The 6th MPR Cavalry Division roughly 1250 men had 2 small regiments, 4 76 mm guns, armored cars, and a training company. Bykov arrayed north to south: 2 Soviet infantry on flanks, MPR cavalry center, unorthodox, as cavalry suits flanks. Spread over 10 miles parallel to but east of the Halha, 1 mile west of Nomonhan. Reserves: 1 infantry company, engineers, and artillery west of the river near the bridge; Shoaaiibuu's guns also west to avoid sand. Japanese held initial edges in numbers and surprise, especially versus MPR cavalry. Offsets: Yamagata split into 5 weaker units; radios failed early, hampering coordination; Soviets dominated firepower with self propelled guns, 4 MPR pieces, and BA 6s, armored fighters with 45 mm turret guns, half track capable, 27 mph speed, but thin 9 mm armor vulnerable to close heavy machine guns. Morning of May 28, Yamagata's infantry struck Soviet MPR near Nomonhan, routing lightly armed MPR cavalry and forcing Soviet retreats toward the Halha. Shoaaiibuu rushed his training company forward; Japanese overran his post, killing him and most staff. As combat neared the river, Soviet artillery and armored cars slowed Yamagata. He redirected to a low hill miles east of the Halha with dug in Soviets—failing to notify Azuma. Bykov regrouped 1 to 2 miles east of the Halha Holsten junction, holding firm. By late morning, Yamagata stalled, digging in against Soviet barrages. Azuma, radio silent due to faults, neared the bridge to find robust Soviet defenses. Artillery commander Lieutenant Yu Vakhtin shifted his 4 76 mm guns east to block seizure. Azuma lacked artillery or anti tank tools, unable to advance. With Yamagata bogged down, Azuma became encircled, the encirclers encircled. Runners reached Yamagata, but his dispersed units couldn't rally or breakthrough. By noon, Azuma faced infantry and cavalry from the east, bombardments from west (both Halha sides). Dismounted cavalry dug sandy defenses. Azuma could have broken out but held per mission, awaiting Yamagata, unaware of the plan shift. Pressure mounted: Major I M Remizov's full 149th Regiment recent Tamsag Bulak arrivals trucked in, tilting odds. Resupply failed; ammo dwindled. Post dusk slackening: A major urged withdrawal; Azuma refused, deeming retreat shameful without orders, a Japanese army hallmark, where "retreat" was taboo, replaced by euphemisms like "advance in a different direction." Unauthorized pullback meant execution. Dawn May 29: Fiercer Soviet barrage, 122 mm howitzers, field guns, mortars, armored cars collapsed trenches. An incendiary hit Azuma's sedan, igniting trucks with wounded and ammo. By late afternoon, Soviets closed to 50 yards on 3 fronts; armored cars breached rear. Survivors fought desperately. Between 6:00 and 7:00 p.m., Azuma led 24 men in a banzai charge, cut down by machine guns. A wounded medical lieutenant ordered escapes; 4 succeeded. Rest killed or captured. Komatsubara belatedly reinforced Yamagata on May 29 with artillery, anti tank guns, and fresh infantry. Sources claim Major Tsuji arrived, rebuked Yamagata for inaction, and spurred corpse recovery over 3 nights, yielding ~200 bodies, including Azuma's. Yamagata withdrew to Kanchuerhmiao, unable to oust foes. Ironically, Remizov mistook recovery truck lights for attacks, briefly pulling back west on May 30. By June 3, discovering the exit, Soviet MPR reoccupied the zone. Japanese blamed: (1) poor planning/recon by Komatsubara and Yamagata, (2) comms failures, (3) Azuma's heavy weapon lack. Losses: ~200 Azuma dead, plus 159 killed, 119 wounded, 12 missing from main force, total 500, 25% of detachment. Soviets praised Vakhtin for thwarting pincers. Claims: Bykov 60 to 70 casualties; TASS 40 killed, 70 wounded total Soviet/MPR. Recent Russian: 138 killed, 198 wounded. MPR cavalry hit hard by Japanese and friendly fire. Soviet media silent until June 26; KwAHQ censored, possibly misleading Tokyo. May 30: Kwantung Chief of Staff General Rensuke Isogai assured AGS of avoiding prolongation via heavy frontier blows, downplaying Soviet buildup and escalation. He requested river crossing gear urgently. This hinted at Halha invasion (even per Japanese borders: MPR soil). AGS's General Gun Hashimoto affirmed trust in localization: Soviets' vexations manageable, chastisement easy. Colonel Masazumi Inada's section assessed May 31: 1. USSR avoids expansion. 2. Trust Kwantung localization. 3. Intervene on provocative acts like deep MPR air strikes. Phase 1 ended: Kwantung called it mutual win loss, but inaccurate, Azuma destroyed, heavy tolls, remorse gnawing Komatsubara. On June 1, 1939, an urgent summons from Moscow pulled the young deputy commander of the Byelorussian Military District from Minsk to meet Defense Commissar Marshal Kliment Voroshilov. He boarded the first train with no evident concern, even as the army purges faded into memory. This rising cavalry- and tank-expert, Georgy Konstantinovich Zhukov, would later help defend Moscow in 1941, triumph at Stalingrad and Kursk, and march to Berlin as a Hero of the Soviet Union.Born in 1896 to a poor family headed by a cobbler, Zhukov joined the Imperial Army in 1915 as a cavalryman. Of average height but sturdy build, he excelled in horsemanship and earned the Cross of St. George and noncommissioned status for bravery in 1916. After the October Revolution, he joined the Red Army and the Bolshevik Party, fighting in the Civil War from 1918 to 1921. His proletarian roots, tactical skill, and ambition propelled him: command of a regiment by 1923, a division by 1931. An early advocate of tanks, he survived the purges, impressing superiors as a results-driven leader and playing a key role in his assignment to Mongolia. In Voroshilov's office on June 2, Zhukov learned of recent clashes. Ordered to fly east, assess the situation, and assume command if needed, he soon met acting deputy chief Ivan Smorodinov, who urged candid reports. Europe's war clouds and rising tensions with Japan concerned the Kremlin. Hours later, Zhukov and his staff flew east. Arriving June 5 at Tamsag Bulak (57th Corps HQ), Zhukov met the staff and found Corps Commander Nikolai Feklenko and most aides clueless; only Regimental Commissar M. S. Nikishev had visited the front. Zhukov toured with Nikishev that afternoon and was impressed by his grasp. By day's end, Zhukov bluntly reported: this is not a simple border incident; the Japanese are likely to escalate; the 57th Corps is inadequate. He suggested holding the eastern Halha bridgehead until reinforcements could enable a counteroffensive, and he criticized Feklenko. Moscow replied on June 6: relieve Feklenko; appoint Zhukov. Reinforcements arrived: the 36th Mechanized Infantry Division; the 7th, 8th, and 9th Mechanized Brigades; the 11th Tank Brigade; the 8th MPR Cavalry Division; a heavy artillery regiment; an air wing of more than 100 aircraft, including 21 pilots who had earned renown in the Spanish Civil War. The force was redesignated as the First Army Group. In June, these forces surged toward Tamsag Bulak, eighty miles west of Halha. However, General Michitaro Komatsubara's 23rd Division and the Kwantung Army Headquarters missed the buildup and the leadership change, an intelligence failure born of carelessness and hubris and echoing May's Azuma disaster, with grave battlefield consequences. Early June remained relatively quiet: the Soviet MPR expanded the east-bank perimeter modestly; there was no major Japanese response. KwAHQ's Commander General Kenkichi Ueda, hoping for a quick closure, toured the Fourth Army from May 31 to June 18. Calm broke on June 19. Komatsubara reported two Soviet strikes inside Manchukuo: 15 planes hit Arshan, inflicting casualties on men and horses; 30 aircraft set fire to 100 petroleum barrels near Kanchuerhmiao. In fact, the raids were less dramatic than described: not on Kanchuerhmiao town (a 3,000-person settlement, 40 miles northwest of Nomonhan) but on a supply dump 12 miles south of it. "Arshan" referred to a small village near the border, near Arshanmiao, a Manchukuoan cavalry depot, not a major railhead at Harlun Arshan 100 miles southeast. The raids were strafing runs rather than bombs. Possibly retaliation for May 15's Japanese raid on the MPR Outpost 7 (two killed, 15 wounded) or a response to Zhukov's bridgehead push. Voroshilov authorized the action; motive remained unclear. Nonetheless, KwAHQ, unused to air attacks after dominating skies in Manchuria, Shanghai (1932), and China, was agitated. The situation resembled a jolt akin to the 1973 North Vietnamese strike on U.S. bases in Thailand: not unprovoked, but shocking. Midday June 19, the Operations Staff met. Major Masanobu Tsuji urged swift reprisal; Colonel Masao Terada urged delay in light of the Tientsin crisis (the new Japanese blockade near Peking). Tsuji argued that firmness at Nomonhan would impress Britain; inaction would invite deeper Soviet bombardments or invasion. He swayed Chief Colonel Takushiro Hattori and others, including Terada. They drafted a briefing: the situation was grave; passivity risked a larger invasion and eroded British respect for Japanese might. After two hours of joint talks, most KwAHQ members supported a strong action. Tsuji drafted a major Halha crossing plan to destroy Soviet MPR forces. Hattori and Terada pressed the plan to Chief of Staff General Rensuke Isogai, an expert on Manchukuo affairs but not operations; he deferred to Deputy General Otozaburo Yano, who was absent. They argued urgency; Isogai noted delays in AGS approval. The pair contended for local Kwantung prerogative, citing the 1937 Amur cancellation; AGS would likely veto. Under pressure, Isogai assented, pending Ueda's approval. Ueda approved but insisted that the 23rd Division lead, not the 7th. Hattori noted the 7th's superiority (four regiments in a "square" arrangement versus the 23rd's three regiments, with May unreliability). Ueda prioritized Komatsubara's honor: assigning another division would imply distrust; "I'd rather die." The plan passed on June 19, an example of gekokujo in action. The plan called for reinforcing the 23rd with: the 2nd Air Group (180 aircraft, Lieutenant General Tetsuji Gigi); the Yasuoka Detachment (Lieutenant General Masaomi Yasuoka: two tank regiments, motorized artillery, and the 26th Infantry of the 7th). Total strength: roughly 15,000 men, 120 guns, 70 tanks, 180 aircraft. KwAHQ estimated the enemy at about 1,000 infantry, 10 artillery pieces, and about 12 armored vehicles, expecting a quick victory. Reconnaissance to Halha was curtailed to avoid alerting the Soviets. Confidence ran high, even as intel warned otherwise. Not all leaders were convinced: the 23rd's ordnance colonel reportedly committed suicide over "awful equipment." An attaché, Colonel Akio Doi, warned of growing Soviet buildup, but operations dismissed the concern. In reality, Zhukov's force comprised about 12,500 men, 109 guns, 186 tanks, 266 armored cars, and more than 100 aircraft, offset by the Soviets' armor advantage. The plan echoed Yamagata's failed May 28 initiative: the 23rd main body would seize the Fui Heights (11 miles north of Halha's Holsten junction), cross by pontoon, and sweep south along the west bank toward the Soviet bridge. Yasuoka would push southeast of Halha to trap and destroy the enemy at the junction. On June 20, Tsuji briefed Komatsubara at Hailar, expressing Ueda's trust while pressing to redeem May's failures. Limited pontoon capacity would not support armor; the operation would be vulnerable to air power. Tsuji's reconnaissance detected Soviet air presence at Tamsag Bulak, prompting a preemptive strike and another plan adjustment. KwAHQ informed Tokyo of the offensive in vague terms (citing raids but withholding air details). Even this caused debate; Minister Seishiro Itagaki supported Ueda's stance, favoring a limited operation to ease nerves. Tokyo concurred, unaware of the air plans. Fearing a veto on the Tamsag Bulak raid (nearly 100 miles behind MPR lines), KwAHQ shielded details from the Soviets and Tokyo. A June 29–30 ground attack was prepared; orders were relayed by courier. The leak reached Tokyo on June 24. Deputy Chief General Tetsuzo Nakajima telegrammed three points: 1) AGS policy to contain the conflict and avoid West MPR air attacks; 2) bombing risks escalation; 3) sending Lieutenant Colonel Yadoru Arisue on June 25 for liaison. Polite Japanese diplomatic phrasing allowed Operations to interpret the message as a suggestion. To preempt Arisue's explicit orders, Tsuji urged secrecy from Ueda, Isogai, and Yano, and an advanced raid to June 27. Arisue arrived after the raid on Tamsag Bulak and Bain Tumen (deeper into MPR territory, now near Choibalsan). The Raid resulted in approximately 120 Japanese planes surprising the Soviets, grounding and destroying aircraft and scrambling their defense. Tsuji, flying in a bomber, claimed 25 aircraft destroyed on the ground and about 100 in the air. Official tallies reported 98 destroyed and 51 damaged; ground kills estimated at 50 to 60 at Bain Tumen. Japanese losses were relatively light: one bomber, two fighters, one scout; seven dead. Another Japanese bomber was shot down over MPR, but the crew was rescued. The raid secured air superiority for July. Moscow raged over the losses and the perceived failure to warn in time. In the purge era, blame fell on suspected spies and traitors; Deputy Mongolian Commander Luvsandonoi and ex-57th Deputy A. M. Kushchev were accused, arrested, and sent to Moscow. Luvsandonoi was executed; Kushchev received a four-year sentence, later rising to major general and Hero. KwAHQ celebrated; Operations notified AGS by radio. Colonel Masazumi Inada rebuked: "You damned idiot! What do you think the true meaning of this little success is?" A withering reprimand followed. Stunned but unrepentant, KwAHQ soon received Tokyo's formal reprimand: "Report was received today regarding bombing of Outer Mongolian territory by your air units… . Since this action is in fundamental disagreement with policy which we understood your army was taking to settle incident, it is extremely regretted that advance notice of your intent was not received. Needless to say, this matter is attended with such farreaching consequences that it can by no means be left to your unilateral decision. Hereafter, existing policy will be definitely and strictly observed. It is requested that air attack program be discontinued immediately" By Order of the Chief of Staff By this time, Kwantung Army staff officers stood in high dudgeon. Tsuji later wrote that "tremendous combat results were achieved by carrying out dangerous operations at the risk of our lives. It is perfectly clear that we were carrying out an act of retaliation. What kind of General Staff ignores the psychology of the front lines and tramples on their feelings?" Tsuji drafted a caustic reply, which Kwantung Army commanders sent back to Tokyo, apparently without Ueda or other senior KwAHQ officers' knowledge: "There appear to be certain differences between the Army General Staff and this Army in evaluating the battlefield situation and the measures to be adopted. It is requested that the handling of trivial border-area matters be entrusted to this Army." That sarcastic note from KwAHQ left a deep impression at AGS, which felt something had to be done to restore discipline and order. When General Nakajima informed the Throne about the air raid, the emperor rebuked him and asked who would assume responsibility for the unauthorized attack. Nakajima replied that military operations were ongoing, but that appropriate measures would be taken after this phase ended. Inada sent Terada a telegram implying that the Kwantung Army staff officers responsible would be sacked in due course. Inada pressed to have Tsuji ousted from Kwantung Army immediately, but personnel matters went through the Army Ministry, and Army Minister Itagaki, who knew Tsuji personally, defended him. Tokyo recognized that the situation was delicate; since 1932, Kwantung Army had operated under an Imperial Order to "defend Manchukuo," a broad mandate. Opinions differed in AGS about how best to curb Kwantung Army's operational prerogatives. One idea was to secure Imperial sanction for a new directive limiting Kwantung Army's autonomous combat actions to no more than one regiment. Several other plans circulated. In the meantime, Kwantung Army needed tighter control. On June 29, AGS issued firm instructions to KwAHQ: Directives: a) Kwantung Army is responsible for local settlement of border disputes. b) Areas where the border is disputed, or where defense is tactically unfeasible, need not be defended. Orders: c) Ground combat will be limited to the border region between Manchukuo and Outer Mongolia east of Lake Buir Nor. d) Enemy bases will not be attacked from the air. With this heated exchange of messages, the relationship between Kwantung Army and AGS reached a critical moment. Tsuji called it the "breaking point" between Hsinking and Tokyo. According to Colonel Inada, after this "air raid squabble," gekokujo became much more pronounced in Hsinking, especially within Kwantung Army's Operations Section, which "ceased making meaningful reports" to the AGS Operations Section, which he headed. At KwAHQ, the controversy and the perception of AGS interference in local affairs hardened the resolve of wavering staff officers to move decisively against the USSR. Thereafter, Kwantung Army officers as a group rejected the General Staff's policy of moderation in the Nomonhan incident. Tsuji characterized the conflict between Kwantung Army and the General Staff as the classic clash between combat officers and "desk jockeys." In his view, AGS advocated a policy of not invading enemy territory even if one's own territory was invaded, while Kwantung Army's policy was not to allow invasion. Describing the mindset of the Kwantung Army (and his own) toward the USSR in this border dispute, Tsuji invoked the samurai warrior's warning: "Do not step any closer or I shall be forced to cut you down." Tsuji argued that Kwantung Army had to act firmly at Nomonhan to avoid a larger war later. He also stressed the importance, shared by him and his colleagues, of Kwantung Army maintaining its dignity, which he believed was threatened by both enemy actions and the General Staff. In this emotionally charged atmosphere, the Kwantung Army launched its July offensive. The success of the 2nd Air Group's attack on Tamsag Bulak further inflated KwAHQ's confidence in the upcoming offensive. Although aerial reconnaissance had been intentionally limited to avoid alarming or forewarning the enemy, some scout missions were flown. The scouts reported numerous tank emplacements under construction, though most reports noted few tanks; a single report of large numbers of tanks was downplayed at headquarters. What drew major attention at KwAHQ were reports of large numbers of trucks leaving the front daily and streaming westward into the Mongolian interior. This was interpreted as evidence of a Soviet pullback from forward positions, suggesting the enemy might sense the imminent assault. Orders were issued to speed up final preparations for the assault before Soviet forces could withdraw from the area where the Japanese "meat cleaver" would soon dismember them. What the Japanese scouts had actually observed was not a Soviet withdrawal, but part of a massive truck shuttle that General Grigori Shtern, now commander of Soviet Forces in the Far East, organized to support Zhukov. Each night, Soviet trucks, from distant MPR railway depots to Tamsag Bulak and the combat zone, moved eastward with lights dimmed, carrying supplies and reinforcements. By day, the trucks returned westward for fresh loads. It was these returning trucks, mostly empty, that the Japanese scouts sighted. The Kwantung interpretation of this mass westbound traffic was a serious error, though understandable. The Soviet side was largely ignorant of Japanese preparations, partly because the June 27 air raid had disrupted Soviet air operations, including reconnaissance. In late June, the 23rd Division and Yasuoka's tank force moved from Hailar and Chiangchunmiao toward Nomonhan. A mix of military and civilian vehicles pressed into service, but there was still insufficient motorized transport to move all troops and equipment at once. Most infantry marched the 120 miles to the combat zone, under a hot sun, carrying eighty-pound loads. They arrived after four to six days with little time to recover before the scheduled assault. With Komatsubara's combined force of about 15,000 men, 120 guns, and 70 tanks poised to attack, Kwantung Army estimated Soviet-MPR strength near Nomonhan and the Halha River at about 1,000 men, perhaps ten anti-aircraft guns, ten artillery pieces, and several dozen tanks. In reality, Japanese air activity, especially the big raid of June 27, had put the Soviets on alert. Zhukov suspected a ground attack might occur, though nothing as audacious as a large-scale crossing of the Halha was anticipated. During the night of July 1, Zhukov moved his 11th Tank Brigade, 7th Mechanized Brigade, and 24th Mechanized Infantry Regiment (36th Division) from their staging area near Tamsag Bulak to positions just west of the Halha River. Powerful forces on both sides were being marshaled with little knowledge of the enemy's disposition. As the sun scorched the Mongolian steppes, the stage was set for a clash that would echo through history. General Komatsubara's 23rd Division, bolstered by Yasuoka's armored might and the skies commanded by Gigi's air group, crept toward the Halha River like a predator in the night. Fifteen thousand Japanese warriors, their boots heavy with dust and resolve, prepared to cross the disputed waters and crush what they believed was a faltering foe. Little did they know, Zhukov's reinforcements, tanks rumbling like thunder, mechanized brigades poised in the shadows, had transformed the frontier into a fortress of steel. Miscalculations piled like sand dunes: Japanese scouts mistook supply convoys for retreats, while Soviet eyes, blinded by the June raid, underestimated the impending storm. Kwantung's gekokujo spirit burned bright, defying Tokyo's cautions, as both sides hurtled toward a brutal reckoning. What began as border skirmishes now threatened to erupt into full-scale war, testing the mettle of empires on the edge.

Patrols in May led to failed Japanese offensives, like Colonel Yamagata's disastrous assault and the Azuma detachment's annihilation. Tensions rose with air raids, including Japan's June strike on Soviet bases. By July, misjudged intelligence set the stage for a major confrontation, testing imperial ambitions amid global war clouds.

3.188 Fall and Rise of China: From Changkufeng to Nomonhan

Last time we spoke about The Battle of Suixian–Zaoyang-Shatow. Following the brutal 1938 capture of Wuhan, Japanese forces aimed to solidify their hold by launching an offensive against Chinese troops in the 5th War Zone, a rugged natural fortress in northern Hubei and southern Henan. Under General Yasuji Okamura, the 11th Army deployed three divisions and cavalry in a pincer assault starting May 1, 1939, targeting Suixian and Zaoyang to crush Nationalist resistance and secure flanks. Chinese commander Li Zongren, leveraging terrain like the Dabie and Tongbai Mountains, orchestrated defenses with over 200,000 troops, including Tang Enbo's 31st Army Group. By May 23, they recaptured Suixian and Zaoyang, forcing a Japanese withdrawal with heavy losses, over 13,000 Japanese casualties versus 25,000 Chinese, restoring pre-battle lines. Shifting south, Japan targeted Shantou in Guangdong to sever supply lines from Hong Kong. In a massive June 21 amphibious assault, the 21st Army overwhelmed thin Chinese defenses, capturing the port and Chao'an despite guerrilla resistance led by Zhang Fakui. Though losses mounted, Japan tightened its blockade, straining China's war effort amid ongoing attrition. #188 From Changkufeng to Nomonhan 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. Well hello again, and yes you all have probably guessed we are taking another detour. Do not worry I hope to shorten this one a bit more so than what became a sort of mini series on the battle of Changkufeng or Battle of Lake Khasan. What we are about to jump into is known in the west as the battle of khalkin Gol, by the Japanese the Nomohan incident. But first I need to sort of set the table up so to say. So back on August 10th, 1938 the Litvinov-Shigemitsu agreement established a joint border commission tasked with redemarcating the disputed boundary between the Soviet Union and Japanese-controlled Manchukuo. However, this commission never achieved a mutually agreeable definition of the border in the contested area. In reality, the outcome was decided well before the group's inaugural meeting. Mere hours after the cease-fire took effect on the afternoon of August 11, General Grigory Shtern convened with a regimental commander from Japan's 19th Division to coordinate the disengagement of forces. With the conflict deemed "honorably" concluded, Japan's Imperial General Headquarters mandated the swift withdrawal of all Japanese troops to the west bank of the Tumen River. By the night of August 13, as the final Japanese soldier crossed the river, it effectively became the de facto border. Soviet forces promptly reoccupied Changkufeng Hill and the adjacent heights—a move that would carry unexpected and profound repercussions. Authoritative Japanese military analyses suggest that if negotiations in Moscow had dragged on for just one more day, the 19th Division would likely have been dislodged from Changkufeng and its surrounding elevations. Undoubtedly, General Shtern's infantry breathed a sigh of relief as the bloodshed ceased. Yet, one can't help but question why Moscow opted for a cease-fire at a juncture when Soviet troops were on the cusp of total battlefield triumph. Perhaps Kremlin leaders deemed it wiser to settle for a substantial gain, roughly three-quarters of their objectives, rather than risk everything. After all, Japan had mobilized threatening forces in eastern Manchuria, and the Imperial Army had a history of impulsive, unpredictable aggression. Moreover, amid the escalating crisis over Czechoslovakia, Moscow may have been wary of provoking a broader Asian conflict. Another theory posits that Soviet high command was misinformed about the ground situation. Reports of capturing a small segment of Changkufeng's crest might have been misinterpreted as control over the entire ridge, or an imminent full takeover before midnight on August 10. The unexpected phone call from Foreign Minister Maxim Litvinov to the Japanese embassy that night—proposing a one-kilometer Japanese retreat in exchange for a cease-fire along existing lines—hints at communication breakdowns between Shtern's headquarters and the Kremlin. Ironically, such lapses may have preserved Japanese military honor, allowing the 19th Division's evacuation through diplomacy rather than defeat. Both sides endured severe losses. Initial Japanese press reports claimed 158 killed and 740 wounded. However, the 19th Division's medical logs reveal a grimmer toll: 526 dead and 914 injured, totaling 1,440 casualties. The true figure may have climbed higher, possibly to 1,500–2,000. Following the armistice, the Soviet news agency TASS reported 236 Red Army fatalities and 611 wounded. Given Shtern's uphill assaults across open terrain against entrenched positions, these numbers seem understated. Attackers in such scenarios typically suffered two to three times the defenders' losses, suggesting Soviet casualties ranged from 3,000 to 5,000. This aligns with a Soviet Military Council investigation on August 31, 1938, which documented 408 killed and 2,807 wounded. Japanese estimates placed Soviet losses even higher, at 4,500–7,000. Not all victims perished in combat. Marshal Vasily Blyukher, a decorated Soviet commander, former warlord of the Far East, and Central Committee candidate, was summoned to Moscow in August 1938. Relieved of duty in September and arrested with his family in October, he faced charges of inadequate preparation against Japanese aggression and harboring "enemies of the people" within his ranks. On November 9, 1938, Blyukher died during interrogation a euphemism for torture-induced death.Other innocents suffered as well. In the wake of the fighting, Soviet authorities deported hundreds of thousands of Korean rice farmers from the Ussuri region to Kazakhstan, aiming to eradicate Korean settlements that Japanese spies had allegedly exploited. The Changkufeng clash indirectly hampered Japan's Wuhan offensive, a massive push to subdue China. The influx of troops and supplies for this campaign was briefly disrupted by the border flare-up. Notably, Kwantung Army's 2nd Air Group, slated for Wuhan, was retained due to the Soviet threat. Chiang Kai-shek's drastic measure, breaching the Yellow River dikes to flood Japanese advance routes—further delayed the assault. By October 25, 1938, when Japanese forces captured Hankow, Chiang had relocated his capital to distant Chungking. Paradoxically, Wuhan's fall cut rail links from Canton inland, heightening Chiang's reliance on Soviet aid routed overland and by air from Central Asia. Japan secured a tactical win but missed the decisive blow; Chinese resistance persisted, pinning down a million Japanese troops in occupation duties. What was the true significance of Changkufeng? For General Koiso Suetaka and the 19th Division, it evoked a mix of bitterness and pride. Those eager for combat got their share, though not on their terms. To veterans mourning fallen comrades on those desolate slopes, it might have felt like senseless tragedy. Yet, they fought valiantly under dire conditions, holding firm until a retreat that blended humiliation with imperial praise, a bittersweet inheritance. For the Red Army, it marked a crucial trial of resolve amid Stalin's purges. While Shtern's forces didn't shine brilliantly, they acquitted themselves well in adversity. The U.S. military attaché in Moscow observed that any purge-related inefficiencies had been surmounted, praising the Red Army's valor, reliability, and equipment. His counterpart in China, Colonel Joseph Stilwell, put it bluntly: the Soviets "appeared to advantage," urging skeptics to rethink notions of a weakened Red Army. Yet, by World War II's eve, many British, French, German, and Japanese leaders still dismissed it as a "paper tiger." Soviet leaders appeared content, promoting Shtern to command the Transbaikal Military District and colonel general by 1940, while honoring "Heroes of Lake Khasan" with medals. In a fiery November 7, 1938, speech, Marshal Kliment Voroshilov warned that future incursions would prompt strikes deep into enemy territory. Tokyo's views diverged sharply. Many in the military and government saw it as a stain on Imperial Army prestige, especially Kwantung Army, humiliated on Manchukuo soil it swore to protect. Colonel Masanobu Tsuji Inada, however, framed it as a successful reconnaissance, confirming Soviet border defense without broader aggression, allowing the Wuhan push to proceed safely. Critics, including Major General Gun Hashimoto and historians, questioned this. They argued IGHQ lacked contingency plans for a massive Soviet response, especially with Wuhan preparations underway since June. One expert warned Japan had "played with fire," risking Manchuria and Korea if escalation occurred. Yet, Japanese commanders gleaned few lessons, downplaying Soviet materiel superiority and maintaining disdain for Red Army prowess. The 19th Division's stand against outnumbered odds reinforced this hubris, as did tolerance for local insubordination—attitudes that would prove costly. The Kremlin, conversely, learned Japan remained unpredictable despite its China quagmire. But for Emperor Hirohito's intervention, the conflict might have ballooned. Amid purges and the Czech crisis, Stalin likely viewed it as a reminder of eastern vulnerabilities, especially with Munich advancing German threats westward. Both sides toyed with peril. Moderation won in Tokyo, but Kwantung Army seethed. On August 11, Premier Fumimaro Konoye noted the need for caution. Kwantung, however, pushed for and secured control of the disputed salient from Chosen Army by October 8, 1938. Even winter's chill couldn't quench their vengeful fire, setting the stage for future confrontations. A quick look at the regional map reveals how Manchukuo and the Mongolian People's Republic each jut into the other's territory like protruding salients. These bulges could be seen as aggressive thrusts into enemy land, yet they also risked encirclement and absorption by the opposing empire. A northward push from western Manchuria through Mongolia could sever the MPR and Soviet Far East from the USSR's heartland. Conversely, a pincer movement from Mongolia and the Soviet Maritime Province might envelop and isolate Manchukuo. This dynamic highlights the frontier's strategic volatility in the 1930s. One particularly tense sector was the broad Mongolian salient extending about 150 miles eastward into west-central Manchukuo. There, in mid-1939, Soviet-Japanese tensions erupted into major combat. Known to the Japanese as the Nomonhan Incident and to the Soviets and Mongolians as the Battle of Khalkhin Gol, this clash dwarfed the earlier Changkufeng affair in scale, duration, and impact. Spanning four months and claiming 30,000 to 50,000 casualties, it amounted to a small undeclared war, the modern era's first limited conflict between great powers. The Mongolian salient features vast, semiarid plains of sandy grassland, gently rolling terrain dotted with sparse scrub pines and low shrubs. The climate is unforgivingly continental: May brings hot days and freezing nights, while July and August see daytime highs exceeding 38°C (100°F in American units), with cool evenings. Swarms of mosquitoes and massive horseflies necessitate netting in summer. Rainfall is scarce, but dense morning fogs are common in August. Come September, temperatures plummet, with heavy snows by October and midwinter lows dipping to –34°C. This blend of North African aridity and North Dakotan winters supports only sparse populations, mainly two related but distinct Mongol tribes. The Buriat (or Barga) Mongols migrated into the Nomonhan area from the northwest in the late 17th to early 18th centuries, likely fleeing Russian expansion after the 1689 Treaty of Nerchinsk. Organized by Manchu emperors between 1732 and 1735, they settled east of the river they called Khalkhin Gol (Mongolian for "river"), in lands that would later become Manchukuo. The Khalkha Mongols, named for the word meaning "barrier" or "shield," traditionally guarded the Mongol Empire's northern frontiers. Their territories lay west of the Buriats, in what would become the MPR. For centuries, these tribes herded livestock across sands, river crossings, and desert paths, largely oblivious to any formal borders. For hundreds of years, the line dividing the Mongolian salient from western Manchuria was a hazy administrative divide within the Qing Empire. In the 20th century, Russia's detachment of Outer Mongolia and Japan's seizure of Manchuria transformed this vague boundary into a frontline between rival powers. The Nomonhan Incident ignited over this contested border. Near the salient's northeastern edge, the river, called Khalkhin Gol by Mongols and Soviets, and Halha by Manchurians and Japanese, flows northwest into Lake Buir Nor. The core dispute: Was the river, as Japan asserted, the historic boundary between Manchukuo and the MPR? Soviet and MPR officials insisted the line ran parallel to and 10–12 miles east of the river, claiming the intervening strip. Japan cited no fewer than 18 maps, from Chinese and Japanese sources, to support the river as the border, a logical choice in such barren terrain, where it served as the sole natural divider. Yet, Soviets and Mongolians countered with evidence like a 1919 Chinese postal atlas and maps from Japanese and Manchukuoan agencies (1919–1934). Unbeknownst to combatants, in July 1939, China's military attaché in Moscow shared a 1934 General Staff map with his American counterpart, showing the border east of the river. Postwar Japanese studies of 18th-century Chinese records confirm that in 1734, the Qing emperor set a boundary between Buriat and Khalkha Mongols east of the river, passing through the hamlet of Nomonhan—as the Soviets claimed. However, Kwantung Army Headquarters dismissed this as non-binding, viewing it as an internal Qing affair without Russian involvement. Two former Kwantung Army officers offer a pragmatic explanation: From 1931 to 1935, when Soviet forces in the Far East were weak, Japanese and Manchukuoan authorities imposed the river as the de facto border, with MPR acquiescence. By the mid- to late 1930s, as Soviet strength grew, Japan refused to yield, while Mongolians and Soviets rejected the river line, sparking clashes. In 1935, Kwantung Army revised its maps to align with the river claim. From late that year, the Lake Buir Nor–Halha sector saw frequent skirmishes between Manchukuoan and MPR patrols. Until mid-1938, frontier defense in northwestern Manchukuo fell to the 8th Border Garrison Unit , based near Hailar. This 7,000-man force, spread thin, lacked mobility, training, and, in Kwantung Army's eyes, combat readiness. That summer, the newly formed 23rd Division, under Kwantung Army, took station at Hailar, absorbing the 8th BGU under its command, led by Lieutenant General Michitaro Komatsubara. At 52, Komatsubara was a premier Russian specialist in the Imperial Army, with stints as military attaché in the USSR and head of Kwantung's Special Services Agency in Harbin. Standing 5'7" with a sturdy build, glasses, and a small mustache, he was detail-oriented, keeping meticulous diaries, writing lengthy letters, and composing poetry, though he lacked combat experience. Before departing Tokyo in July 1938, Komatsubara received briefings from Colonel Masazumi Inada, AGS Operations Section chief. Amid planning for Changkufeng, Inada urged calm on the Manchukuo-MPR border given China's ongoing campaigns. Guidelines: Ignore minor incidents, prioritize intelligence on Soviet forces east of Lake Baikal, and study operations against the Soviet Far East's western sector. Familiar with the region from his Harbin days, Komatsubara adopted a low-key approach. Neither impulsive nor aggressive, he kept the green 23rd Division near Hailar, delegating patrols to the 8th BGU. An autumn incident underscores his restraint. On November 1, 1938, an 8th BGU patrol was ambushed by MPR forces. Per Japanese accounts, the three-man team, led by a lieutenant, strayed too close to the border and was attacked 50 meters inside Manchukuo. The lieutenant escaped, but his men died. Komatsubara sent an infantry company to secure the site but forbade retaliation. He pursued body recovery diplomatically, protested to MPR and Soviet officials, and disciplined his officers: garrison leaders got five days' confinement for poor troop training, the lieutenant thirty days. Despite this caution, pressures at AGS and KwAHQ were mounting, poised to thrust the 23rd Division into fierce battle. Modern militaries routinely develop contingency plans against potential adversaries, and the mere existence of such strategies doesn't inherently signal aggressive intentions. That said, shifts in Japan's operational planning vis-à-vis the Soviet Union may have inadvertently fueled the Nomonhan Incident. From 1934 to 1938, Japanese war scenarios emphasized a massive surprise assault in the Ussuri River region, paired with defensive holding actions in northwestern Manchuria. However, between mid-1938 and early 1939, a clandestine joint task force from the Army General Staff and Kwantung Army's Operations Departments crafted a bold new blueprint. This revised strategy proposed containing Soviet forces in the east and north while unleashing a full-scale offensive from Hailar, advancing west-northwest toward Chita and ultimately Lake Baikal. The goal: sever the Transbaikal Soviet Far East from the USSR's core. Dubbed Plan Eight-B, it gained Kwantung Army's endorsement in March 1939. Key architects—Colonels Takushiro Hattori and Masao Terada, along with Major Takeharu Shimanuki—were reassigned from AGS to Kwantung Army Headquarters to oversee implementation. The plan anticipated a five-year buildup before execution, with Hattori assuming the role of chief operations staff officer. A map review exposes a glaring vulnerability in Plan Eight-B: the Japanese advance would leave its southern flank exposed to Soviet counterstrikes from the Mongolian salient. By spring 1939, KwAHQ likely began perceiving this protrusion as a strategic liability. Notably, at the outbreak of Nomonhan hostilities, no detailed operational contingencies for the area had been formalized. Concurrently, Japan initiated plans for a vital railroad linking Harlun Arshan to Hailar. While its direct tie to Plan Eight-B remains unclear, the route skirted perilously close to the Halha River, potentially heightening KwAHQ's focus on the disputed Mongolian salient. In early 1939, the 23rd Division intensified reconnaissance patrols near the river. Around this time, General Grigory Shtern, freshly appointed commander of Soviet Far Eastern forces, issued a public warning that Japan was gearing up for an assault on the Mongolian People's Republic. As Plan Eight-B took shape and railroad proposals advanced, KwAHQ issued a strikingly confrontational set of guidelines for frontier troops. These directives are often cited as a catalyst for the Nomonhan clash, forging a chain linking the 1937 Amur River incident, the 1938 Changkufeng debacle, and the 1939 conflict.Resentment had festered at KwAHQ over perceived AGS meddling during the Amur affair, which curtailed their command autonomy. This frustration intensified at Changkufeng, where General Kamezo Suetaka's 19th Division endured heavy losses, only for the contested Manchukuoan territory to be effectively ceded. Kwantung Army lobbied successfully to wrest oversight of the Changkufeng salient from Chosen Army. In November 1938, Major Masanobu Tsuji of KwAHQ's Operations Section was sent to survey the site. The audacious officer was dismayed: Soviet forces dominated the land from the disputed ridge to the Tumen River. Tsuji undertook several winter reconnaissance missions. His final outing in March 1939 involved leading 40 men to Changkufeng's base. With rifles slung non-threateningly, they ascended to within 200 yards of Soviet lines, formed a line, and urinated in unison, eliciting amused reactions from the enemy. They then picnicked with obentos and sake, sang army tunes, and left gifts of canned meat, chocolates, and whiskey. This theatrical stunt concealed Tsuji's real aim: covert photography proving Soviet fortifications encroached on Manchukuoan soil. Tsuji was a singular figure. Born of modest means, he embodied a modern samurai ethos, channeling a sharp intellect into a frail, often ailing body through feats of extraordinary daring. A creative tactician, he thrived in intelligence ops, political scheming, aerial scouting, planning, and frontline command—excelling across a tumultuous career. Yet, flaws marred his brilliance: narrow bigotry, virulent racism, and capacity for cruelty. Ever the ambitious outsider, Tsuji wielded outsized influence via gekokujo—Japan's tradition of subordinates steering policy from below. In 1939, he was a major, but his pivotal role at Nomonhan stemmed from this dynamic. Back in Hsinking after his Changkufeng escapade, Tsuji drafted a response plan: negotiate border "rectification" with the Soviets; if talks failed, launch an attack to expel intruders. Kwantung Army adopted it. Deputy Chief of Staff Major General Otozaburo Yano flew to Tokyo with Tsuji's photos, seeking AGS approval. There, he was rebuffed—Changkufeng was deemed settled, and minor violations should be overlooked amid Tokyo's aversion to Soviet conflict. Yano's plea that leniency would invite aggression was countered by notes on Europe's tensions restraining Moscow. Yano's return sparked outrage at KwAHQ, seen as AGS thwarting their imperial duty to safeguard Manchukuo. Fury peaked in the Operations Section, setting the stage for Tsuji's drafting of stringent new frontier guidelines: "Principles for the Settlement of Soviet-Manchukuoan Border Disputes." The core tenet: "If Soviet troops transgress the Manchukuoan frontiers, Kwantung Army will nip their ambitions in the bud by completely destroying them." Specific directives for local commanders included: "If the enemy crosses the frontiers … annihilate him without delay, employing strength carefully built up beforehand. To accomplish our mission, it is permissible to enter Soviet territory, or to trap or lure Soviet troops into Manchukuoan territory and allow them to remain there for some time… . Where boundary lines are not clearly defined, area defense commanders will, upon their own initiative, establish boundaries and indicate them to the forward elements… . In the event of an armed clash, fight until victory is won, regardless of relative strengths or of the location of the boundaries. If the enemy violates the borders, friendly units must challenge him courageously and endeavor to triumph in their zone of action without concerning themselves about the consequences, which will be the responsibility of higher headquarters." Major Tsuji Masanobu later justified the new guidelines by pointing to the "contradictory orders" that had hamstrung frontier commanders under the old rules. They were tasked with upholding Manchukuo's territorial integrity yet forbidden from actions that might spark conflict. This, Tsuji argued, bred hesitation, as officers feared repercussions for decisive responses to incursions. The updated directives aimed to alleviate this "anxiety," empowering local leaders to act boldly without personal liability. In truth, Tsuji's "Principles for the Settlement of Soviet-Manchukuoan Border Disputes" were more incendiary than conciliatory. They introduced provocative measures: authorizing commanders to unilaterally define unclear boundaries, enforce them with immediate force "shoot first, ask questions later", permit pursuits into enemy territory, and even encourage luring adversaries across the line. Such tactics flouted both government policy and official army doctrine, prioritizing escalation over restraint. The proposals sparked intense debate within Kwantung Army's Operations Section. Section chief Colonel Takushiro Hattori and Colonel Masao Terada outranked Tsuji, as did Major Takeharu Shimanuki, all recent transfers from the Army General Staff. Tsuji, however, boasted longer tenure at Kwantung Army Headquarters since April 1936 and in Operations since November 1937, making him the de facto veteran. Hattori and Terada hesitated to challenge the assertive major, whose reputation for intellect, persuasion, and deep knowledge of Manchuria commanded respect. In a 1960 interview, Shimanuki recalled Tsuji's dominance in discussions, where his proactive ideas often swayed the group. Unified, the section forwarded Tsuji's plan to Kwantung Army Command. Commander Lieutenant General Kenkichi Ueda consulted Chief of Staff General Rensuke Isogai and Vice Chief General Otozaburo Yano, seasoned leaders who should have spotted the guidelines' volatility. Yet, lingering grudges from AGS "interference" in past incidents like the Amur River and Changkufeng clouded their judgment. Ueda, Isogai, and Tsuji shared history from the 1932 Shanghai Incident: Tsuji, then a captain, led a company in the 7th Regiment under Colonel Isogai, with Yano as staff officer and Ueda commanding the 9th Division. Tsuji was wounded there, forging bonds of camaraderie. This "clique," which grew to include Hattori, Terada, and Shimanuki, amplified Tsuji's influence. Despite Isogai's initial reservations as the group's moderate voice, the guidelines won approval. Ueda issued them as Kwantung Army Operations Order 1488 on April 25, 1939, during a division commanders' conference at KwAHQ. A routine copy reached AGS in Tokyo, but no formal reply came. Preoccupied with the China War and alliance talks with Germany, AGS may have overlooked border matters. Colonel Masazumi Inada, AGS Operations head, later noted basic acceptance of Order 1488, with an informal expectation—relayed to Hattori and Terada—of prior consultation on violations. KwAHQ dismissed this as another Tokyo intrusion on their autonomy. Some Japanese analysts contend a stern AGS rejection might have prevented Nomonhan's catastrophe, though quelling Kwantung's defiance could have required mass staff reassignments, a disruptive step AGS avoided. Tsuji countered that permitting forceful action at Changkufeng would have deterred Nomonhan altogether, underscoring the interconnectedness of these clashes while implicitly critiquing the 1939 battle's location. Undeniably, Order 1488's issuance on April 25 paved the way for conflict three weeks later. Japanese records confirm that Khalkha Mongols and MPR patrols routinely crossed the Halha River—viewed by them as internal territory, 10 miles from the true border. Such crossings passed uneventfully in March and April 1939. Post-Order 1488, however, 23rd Division commander General Michitaro Komatsubara responded aggressively, setting the stage for escalation. The Nomonhan Incident ignited with a border clash on May 11–12, 1939, that rapidly spiraled into a major conflict. Over a dozen "authoritative" accounts exist, varying in viewpoint, focus, and specifics. After cross-referencing these sources, a coherent timeline emerges. On the night of May 10–11, a 20-man Mongolian People's Republic border patrol crossed eastward over the Halha River (known as Khalkhin Gol to Mongols and Soviets). About 10 miles east, atop a 150-foot sandy hill, lay the tiny hamlet of Nomonhan, a cluster of crude huts housing a few Mongol families. Just south flowed the Holsten River, merging westward into the broader Halha. By morning on May 11, Manchukuoan forces spotted the MPR patrol north of the Holsten and west of Nomonhan. In the MPR/Soviet perspective, Nomonhan Hill marked the Mongolia-Manchuria border. To Manchukuoans and Japanese, it sat 10 miles inside Manchukuo, well east of the Halha. A 40-man Manchukuoan cavalry unit repelled the Mongolians back across the river, inflicting initial casualties on both sides—the Manchukuoans drawing first blood. The MPR patrol leader exaggerated the attackers as 200 strong. The next day, May 12, a 60-man MPR force under Major P. Chogdan evicted the Manchukuoans from the disputed zone, reestablishing positions between the Halha and Nomonhan. The Manchukuoans, in turn, reported facing 700 enemies. Sporadic skirmishes and maneuvering persisted through the week. On May 13, two days post-clash, the local Manchukuoan commander alerted General Michitaro Komatsubara's 23rd Division headquarters in Hailar. Simultaneously, Major Chogdan reported to Soviet military command in Ulaanbaatar, Mongolia's capital. What began as a Mongolian-Manchukuoan spat was poised to draw in Soviet and Japanese patrons. Attributing the May 10–11 violation hinges on border interpretations: both sides claimed the Halha-Nomonhan strip. Yet, most accounts concur that Manchukuoan forces initiated the fighting. Post-May 13 notifications to Moscow and Tokyo clarify the record thereafter. Midday on May 13, Komatsubara was leading a staff conference on the newly issued Kwantung Army Operations Order 1488—Major Tsuji Masanobu's aggressive border guidelines. Ironically, the first Nomonhan combat report arrived mid-discussion. Officers present recall Komatsubara deciding instantly to "destroy the invading Outer Mongolian forces" per Order 1488. That afternoon, he informed Kwantung Army Headquarters of the incident and his intent to eradicate the intruders, requesting air support and trucks. General Kenkichi Ueda, Kwantung commander, approved Komatsubara's "positive attitude," dispatching six scout planes, 40 fighters, 10 light bombers, two anti-aircraft batteries, and two motorized transport companies. Ueda added a caveat: exercise "extreme caution" to prevent escalation—a paradoxical blend of destruction and restraint, reflective of KwAHQ's fervent mood. Ueda relayed the details to Tokyo's Army General Staff, which responded that Kwantung should handle it "appropriately." Despite Kwantung's impulsive reputation, Tokyo deferred, perhaps trusting the northern strategic imbalance, eight Japanese divisions versus 30 Soviet ones from Lake Baikal to Vladivostok, would enforce prudence. This faith proved misguided. On May 14, Major Tsuji flew from KwAHQ for aerial reconnaissance over Nomonhan, spotting 20 horses but no troops. Upon landing, a fresh bullet hole in his plane confirmed lingering MPR presence east of the Halha. Tsuji briefed 23rd Division staff and reported to Ueda that the incident seemed minor. Aligning with Order 1488's spirit, Komatsubara deployed a force under Lieutenant Colonel Yaozo Azuma: an armored car company, two infantry companies, and a cavalry troop. Arriving at Nomonhan on May 15, Azuma learned most MPR forces had retreated westward across the Halha the prior night, with only token elements remaining, and those withdrawing. Undeterred, he pursued. The advance met scant resistance, as foes had crossed the river. However, Japanese light bombers struck a small MPR concentration on the west bank, Outpost Number 7, killing two and wounding 15 per MPR reports; Japanese claimed 30–40 kills. All agree: the raid targeted undisputed MPR territory. Hearing of May 15's events, Komatsubara deemed the Mongolians sufficiently rebuked and recalled Azuma to Hailar on May 16. KwAHQ concurred, closing the matter. Soviet leaders, however, saw it differently. Mid-May prompted Soviet support for the MPR under their 1936 Mutual Defense Pact. The Red Army's 57th Corps, stationed in Mongolia, faced initial disarray: Commander Nikolai Feklenko was hunting, Chief of Staff A. M. Kushchev in Ulan Ude with his ill wife. Moscow learned of clashes via international press from Japanese sources, sparking Chief of Staff Boris Shaposhnikov's furious inquiry. Feklenko and Kushchev rushed back to Ulaanbaatar, dispatching a mixed force—a battalion from the 149th Infantry Regiment (36th Division), plus light armor and artillery from the 11th Tank Brigade—to Tamsag Bulak, 80 miles west of the Halha. Led by Major A. E. Bykov, it bolstered the MPR's 6th Cavalry Division. Bykov and Cavalry Commander Colonel Shoaaiibuu inspected the site on May 15, post-Azum's departure. The cavalry arrived two days later, backed by Bykov (ordered to remain west of the river and avoid combat if possible). Some MPR troops recrossed, occupying the disputed zone. Clashes with Manchukuoan cavalry resumed and intensified. Notified of renewed hostilities, Komatsubara viewed it as defiance, a personal affront. Emboldened by Order 1488, he aimed not just to repel but to encircle and annihilate. The incident was on the verge of major expansion.

3.187 Fall and Rise of China: Battle of Suixian–Zaoyang-Shatow

Last time we spoke about the battle of Nanchang. After securing Hainan and targeting Zhejiang–Jiangxi Railway corridors, Japan's 11th Army, backed by armor, air power, and riverine operations, sought a rapid, surgical seizure of Nanchang to sever eastern Chinese logistics and coerce Chongqing. China, reorganizing under Chiang Kai-shek, concentrated over 200,000 troops across 52 divisions in the Ninth and Third War Zones, with Xue Yue commanding the 9th War Zone in defense of Wuhan-Nanchang corridors. The fighting began with German-style, combined-arms river operations along the Xiushui and Gan rivers, including feints, river crossings, and heavy artillery, sometimes using poison gas. From March 20–23, Japanese forces established a beachhead and advanced into Fengxin, Shengmi, and later Nanchang, despite stiff Chinese resistance and bridges being destroyed. Chiang's strategic shift toward attrition pushed for broader offensives to disrupt railways and rear areas, though Chinese plans for a counteroffensive repeatedly stalled due to logistics and coordination issues. By early May, Japanese forces encircled and captured Nanchang, albeit at heavy cost, with Chinese casualties surpassing 43,000 dead and Japanese losses over 2,200 dead. #187 The Battle of Suixian–Zaoyang-Shatow Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

Having seized Wuhan in a brutal offensive the previous year, the Japanese sought not just to hold their ground but to solidify their grip on this vital hub. Wuhan, a bustling metropolis at the confluence of the Yangtze and Han Rivers, had become a linchpin in their strategy, a base from which they could project power across central China. Yet, the city was far from secure, Chinese troops in northern Hubei and southern Henan, perched above the mighty Yangtze, posed an unrelenting threat. To relieve the mounting pressure on their newfound stronghold, the Japanese high command orchestrated a bold offensive against the towns of Suixian and Zaoyang. They aimed to annihilate the main force of the Chinese 5th War Zone, a move that would crush the Nationalist resistance in the region and secure their flanks. This theater of war, freshly designated as the 5th War Zone after the grueling Battle of Wuhan, encompassed a vast expanse west of Shashi in the upper Yangtze basin. It stretched across northern Hubei, southern Henan, and the rugged Dabie Mountains in eastern Anhui, forming a strategic bulwark that guarded the eastern approaches to Sichuan, the very heartland of the Nationalist government's central institutions. Historian Rana Mitter in Forgotten Ally described this zone as "a gateway of immense importance, a natural fortress that could either serve as a launchpad for offensives against Japanese-held territories or a defensive redoubt protecting the rear areas of Sichuan and Shaanxi". The terrain itself was a defender's dream and an attacker's nightmare: to the east rose the imposing Dabie Mountains, their peaks cloaked in mist and folklore; the Tongbai Mountains sliced across the north like a jagged spine; the Jing Mountains guarded the west; the Yangtze River snaked southward, its waters a formidable barrier; the Dahong Mountains dominated the center, offering hidden valleys for ambushes; and the Han River (also known as the Xiang River) carved a north-south path through it all. Two critical transport arteries—the Hanyi Road linking Hankou to Yichang in Hubei, and the Xianghua Road connecting Xiangyang to Huayuan near Hankou—crisscrossed this landscape, integrating the war zone into a web of mobility. From here, Chinese forces could menace the vital Pinghan Railway, that iron lifeline running from Beiping (modern Beijing) to Hankou, while also threatening the Wuhan region itself. In retreat, it provided a sanctuary to shield the Nationalist heartlands. As military strategist Sun Tzu might have appreciated, this area had long been a magnet for generals, its contours shaping the fates of empires since ancient times. Despite the 5th War Zone's intricate troop deployments, marked by units of varying combat prowess and a glaring shortage of heavy weapons, the Chinese forces made masterful use of the terrain to harass their invaders. Drawing from accounts in Li Zongren's memoirs, he noted how these defenders, often outgunned but never outmaneuvered, turned hills into fortresses and rivers into moats. In early April 1939, as spring rains turned paths to mud, Chinese troops ramped up their disruptions along the southern stretches of the Pinghan Railway, striking from both eastern and western flanks with guerrilla precision. What truly rattled the Japanese garrison in Wuhan was the arrival of reinforcements: six full divisions redeployed to Zaoyang, bolstering the Chinese capacity to launch flanking assaults that could unravel Japanese supply lines. Alarmed by this buildup, the Japanese 11th Army, ensconced in the Wuhan area under the command of General Yasuji Okamura, a figure whose tactical acumen would later earn him notoriety in the Pacific War, devised a daring plan. They intended to plunge deep into the 5th War Zone, smashing the core of the Chinese forces and rendering them impotent, thereby neutralizing the northwestern threat to Wuhan once and for all. From April onward, the Japanese mobilized with meticulous preparation, amassing troops equipped with formidable artillery, rumbling tanks, and squadrons of aircraft that darkened the skies. Historians estimate they committed roughly three and a half divisions to this endeavor, as detailed in Edward J. Drea's In the Service of the Emperor: Essays on the Imperial Japanese Army. Employing a classic pincer movement, a two-flank encirclement coupled with a central breakthrough, they aimed for a swift, decisive strike to obliterate the main Chinese force in the narrow Suixian-Zaoyang corridor, squeezed between the Tongbai and Dahong Mountains. The offensive erupted in full fury on May 1, 1939, as Japanese columns surged forward like a tidal wave, their engines roaring and banners fluttering in the dust-choked air. General Li Zongren, the commander of the 5th War Zone, a man whose leadership had already shone in earlier campaigns like the defense of Tai'erzhuang in 1938, issued urgent orders to cease offensive actions against the Japanese and pivot to a defensive stance. Based on intelligence about the enemy's dispositions, Li orchestrated a comprehensive campaign structure, assigning precise defensive roles and battle plans to each unit. This was no haphazard scramble; it was a symphony of strategy, as Li himself recounted in his memoirs, emphasizing the need to exploit the terrain's natural advantages. While various Chinese war zones executed the "April Offensive" from late April to mid-May, actively harrying and containing Japanese forces, the 5th War Zone focused its energies on the southern segment of the Pinghan Railway, assaulting it from both sides in a bid to disrupt logistics. The main force of the 31st Army Group, under the command of Tang Enbo, a general known for his aggressive tactics and later criticized for corruption, shifted from elsewhere in Hubei to Zaoyang, fortifying the zone and posing a dire threat to the Japanese flanks and rear areas. To counter this peril and safeguard transportation along the Wuhan-Pinghan Railway, the Japanese, led by the formidable Okamura, unleashed their assault from the line stretching through Xinyang, Yingshan, and Zhongxiang. Mobilizing the 3rd, 13th, and 16th Divisions alongside the 2nd and 4th Cavalry Brigades, they charged toward the Suixian-Zaoyang region in western Hubei, intent on eradicating the Chinese main force and alleviating the siege-like pressure on Wuhan. In a masterful reorganization, Li Zongren divided his forces into two army groups, the left and right, plus a dedicated river defense army. His strategy was a blend of attrition and opportunism: harnessing the Tongbai and Dahong Mountains, clinging to key towns like lifelines, and grinding down the Japanese through prolonged warfare while biding time for a counterstroke. This approach echoed the Fabian tactics of ancient Rome, wearing the enemy thin before delivering the coup de grâce. The storm broke at dawn on May 1, when the main contingents of the Japanese 16th and 13th Divisions, bolstered by the 4th Cavalry Brigade from their bases in Zhongxiang and Jingshan, hurled themselves against the Chinese 37th and 180th Divisions of the Right Army Group. Supported by droning aircraft that strafed from above and tanks that churned the earth below, the Japanese advanced with mechanical precision. By May 4, they had shattered the defensive lines flanking Changshoudian, then surged along the east bank of the Xiang River toward Zaoyang in a massive offensive. Fierce combat raged through May 5, as described in Japanese war diaries compiled in Senshi Sōsho (the official Japanese war history series), where soldiers recounted the relentless Chinese resistance amid the smoke and clamor. The Japanese finally breached the defenses, turning their fury on the 122nd Division of the 41st Army. In a heroic stand, the 180th Division clung to Changshoudian, providing cover for the main force's retreat along the east-west Huangqi'an line. The 37th Division fell back to the Yaojiahe line, while elements of the 38th Division repositioned into Liushuigou. On May 6, the Japanese seized Changshoudian, punched through Huangqi'an, and drove northward, unleashing a devastating assault on the 122nd Division's positions near Wenjiamiao. Undeterred, Chinese defenders executed daring flanking maneuvers in the Fenglehe, Yaojiahe, Liushuihe, Shuanghe, and Zhangjiaji areas, turning the landscape into a labyrinth of ambushes. May 7 saw the Japanese pressing on, capturing Zhangjiaji and Shuanghe. By May 8, they assaulted Maozifan and Xinji, where ferocious battles erupted, soldiers clashing in hand-to-hand combat amid the ruins. By May 10, the Japanese had overrun Huyang Town and Xinye, advancing toward Tanghe and the northeastern fringes of Zaoyang. Yet, the Tanghe River front witnessed partial Chinese recoveries: remnants of the Right Army Group, alongside troops from east of the Xianghe, reclaimed Xinye. The 122nd and 180th Divisions withdrew north of Tanghe and Fancheng, while the 37th, 38th, and 132nd Divisions steadfastly held the east bank of the Xianghe River. Concurrently, the main force of the Japanese 3rd Division launched from Yingshan against the 84th and 13th Armies of the 11th Group Army in the Suixian sector. After a whirlwind of combat, the Chinese 84th Army retreated to the Taerwan position. On May 2, the 3rd Division targeted the Gaocheng position of the 13th Army within the 31st Group Army; the ensuing clashes in Taerwan and Gaocheng were a maelstrom of fire, with the Taerwan position exchanging hands multiple times like a deadly game of tug-of-war. By May 4, in a grim escalation, Japanese forces deployed poison gas, a violation of international norms that drew condemnation and is documented in Allied reports from the era, inflicting horrific casualties and compelling the Chinese to relinquish Gaocheng, which fell into enemy hands. On May 5, backed by aerial bombardments, tank charges, and artillery barrages, the Japanese renewed their onslaught along the Gaocheng River and the Lishan-Jiangjiahe line. By May 6, the beleaguered Chinese were forced back to the Tianhekou and Gaocheng line. Suixian succumbed on May 7. On May 8, the Japanese shattered the second line of the 84th Army, capturing Zaoyang and advancing on the Jiangtoudian position of the 85th Army. To evade encirclement, the defenders mounted a valiant resistance before withdrawing from Jiangtoudian; the 84th Army relocated to the Tanghe and Baihe areas, while the 39th Army embedded itself in the Dahongshan for guerrilla operations—a tactic that would bleed the Japanese through hit-and-run warfare, as noted in guerrilla warfare studies by Mao Zedong himself. By May 10, the bulk of the 31st Army Group maneuvered toward Tanghe, reaching north of Biyang by May 15. From Xinyang, Japanese forces struck at Tongbai on May 8; by May 10, elements from Zaoyang advanced to Zhangdian Town and Shangtun Town. In response, the 68th Army of the 1st War Zone dispatched the 143rd Division to defend Queshan and Minggang, and the 119th Division to hold Tongbai. After staunchly blocking the Japanese, they withdrew on May 11 to positions northwest and southwest of Tongbai, shielding the retreat of 5th War Zone units. The Japanese 4th Cavalry Brigade drove toward Tanghe, seizing Tanghe County on May 12. But the tide was turning. In a brilliant reversal, the Fifth War Zone commanded the 31st Army Group, in concert with the 2nd Army Group from the 1st War Zone, to advance from southwestern Henan. Their mission: encircle the bulk of Japanese forces on the Xiangdong Plain and deliver a crushing blow. The main force of the 33rd Army Group targeted Zaoyang, while other units pinned down Japanese rear guards in Zhongxiang. The Chinese counteroffensive erupted with swift successes, Tanghe County was recaptured on May 14, and Tongbai liberated on May 16, shattering the Japanese encirclement scheme. On May 19, after four grueling days of combat, Chinese forces mauled the retreating Japanese, reclaiming Zaoyang and leaving the fields strewn with enemy dead. The 39th Army of the Left Army Group dispersed into the mountains for guerrilla warfare, a shadowy campaign of sabotage and surprise. Forces of the Right Army Group east of the river, along with river defense units, conducted relentless raids on Japanese rears and supply lines over multiple days, sowing chaos before withdrawing to the west bank of the Xiang River on May 21. On May 22, they pressed toward Suixian, recapturing it on May 23. The Japanese, battered and depleted, retreated to their original garrisons in Zhongxiang and Yingshan, restoring the pre-war lines as the battle drew to a close. Throughout this clash, the Chinese held a marked superiority in manpower and coordination, though their deployments lacked full flexibility, briefly placing them on the defensive. After protracted, blood-soaked fighting, they restored the original equilibrium. Despite grievous losses, the Chinese thwarted the Japanese encirclement and exacted a heavy toll, reports from the time, corroborated by Japanese records in Senshi Sōsho, indicate over 13,000 Japanese killed or wounded, with more than 5,000 corpses abandoned on the battlefield. This fulfilled the strategic goal of containing and eroding Japanese strength. Chinese casualties surpassed 25,000, a testament to the ferocity of the struggle. The 5th War Zone seized the initiative in advances and retreats, deftly shifting to outer lines and maintaining positional advantages. As Japanese forces withdrew, Chinese pursuers harried and obstructed them, yielding substantial victories. The Battle of Suizao spanned less than three weeks. The Japanese main force pierced defenses on the east bank of the Han River, advancing to encircle one flank as planned. However, the other two formations met fierce opposition near Suixian and northward, stalling their progress. Adapting to the battlefield's ebb and flow, the Fifth War Zone transformed its tactics: the main force escaped encirclement, maneuvered to outer lines for offensives, and exploited terrain to hammer the Japanese. The pivotal order to flip from defense to offense doomed the encirclement; with the counterattack triumphant, the Japanese declined to hold and retreated. The Chinese pursued with unyielding vigor. By May 24, they had reclaimed Zaoyang, Tongbai, and other locales. Save for Suixian County, the Japanese had fallen back to pre-war positions, reinstating the regional status quo. Thus, the battle concluded, a chapter of resilience etched into the chronicles of China's defiance. In the sweltering heat of southern China, where the humid air clung to every breath like a persistent fog, the Japanese General Staff basked in what they called a triumphant offensive and defensive campaign in Guangdong. But victory, as history so often teaches, is a double-edged sword. By early 1939, the strain was palpable. Their secret supply line snaking from the British colony of Hong Kong to the Chinese mainland was under constant disruption, raids by shadowy guerrilla bands, opportunistic smugglers, and the sheer unpredictability of wartime logistics turning what should have been a lifeline into a leaky sieve. Blockading the entire coastline? A pipe dream, given the vast, jagged shores of Guangdong, dotted with hidden coves and fishing villages that had evaded imperial edicts for centuries. Yet, the General Staff's priorities were unyielding, laser-focused on strangling the Nationalist capital of Chongqing through a relentless blockade. This meant the 21st Army, that workhorse of the Japanese invasion force, had to stay in the fight—no rest for the weary. Drawing from historical records like the Senshi Sōsho (War History Series) compiled by Japan's National Institute for Defense Studies, we know that after the 21st Army reported severing what they dubbed the "secret transport line" at Xinhui, a gritty, hard-fought skirmish that left the local landscape scarred with craters and abandoned supply crates, the General Staff circled back to the idea of a full coastal blockade. It was a classic case of military opportunism: staff officers, poring over maps in dimly lit war rooms in Tokyo, suddenly "discovered" Shantou as a major port. Not just any port, mind you, but a bustling hub tied to the heartstrings of Guangdong's overseas Chinese communities. Shantou and nearby Chao'an weren't mere dots on a map; they were the ancestral hometowns of countless Chaoshan people who had ventured abroad to Southeast Asia, sending back remittances that flowed like lifeblood into the region. Historical economic studies, such as those in The Overseas Chinese in the People's Republic of China by Stephen Fitzgerald, highlight how these funds from the Chaoshan diaspora, often funneled through family networks in places like Singapore and Thailand, were substantial, indirectly fueling China's war effort by sustaining local economies and even purchasing arms on the black market. The Chao-Shao Highway, that dusty artery running near Shantou, was pinpointed as a critical vein connecting Hong Kong's ports to the mainland's interior. So, in early June 1939, the die was cast: Army Order No. 310 thundered from headquarters, commanding the 21st Army to seize Shantou. The Chief of the General Staff himself provided the strategic blueprint, a personal touch that underscored the operation's gravity. The Army Department christened the Chaoshan push "Operation Hua," a nod perhaps to the flowery illusions of easy conquest, while instructing the Navy Department to tag along for the ride. In naval parlance, it became "Operation J," a cryptic label that masked the sheer scale unfolding. Under the Headquarters' watchful eye, what started as a modest blockade morphed into a massive amphibious assault, conjured seemingly out of thin air like a magician's trick, but one with deadly props. The 5th Fleet's orders mobilized an impressive lineup: the 9th Squadron for heavy hitting, the 5th Mine Boat Squadron to clear watery hazards, the 12th and 21st Sweeper Squadrons sweeping for mines like diligent janitors of the sea, the 45th Destroyer Squadron adding destroyer muscle, and air power from the 3rd Combined Air Group (boasting 24 land-based attack aircraft and 9 reconnaissance planes that could spot a fishing boat from miles away). Then there was the Chiyoda Air Group with its 9 reconnaissance aircraft, the Guangdong Air Group contributing a quirky airship and one more recon plane, the 9th Special Landing Squadron from Sasebo trained for beach assaults, and a flotilla of special ships for logistics. On the ground, the 21st Army threw in the 132nd Brigade from the 104th Division, beefed up with the 76th Infantry Battalion, two mountain artillery battalions for lobbing shells over rugged terrain, two engineer battalions to bridge rivers and clear paths, a light armored vehicle platoon rumbling with mechanized menace, and a river-crossing supplies company to keep the troops fed and armed. All under the command of Brigade Commander Juro Goto, a stern officer whose tactical acumen was forged in earlier Manchurian campaigns. The convoy's size demanded rehearsals; the 132nd Brigade trained for boat transfers at Magong in the Penghu Islands, practicing the precarious dance of loading men and gear onto rocking vessels under simulated fire. Secrecy shrouded the whole affair, many officers and soldiers, boarding ships in the dead of night, whispered among themselves that they were finally heading home to Japan, a cruel ruse to maintain operational security. For extra punch, the 21st Army tacked on the 31st Air Squadron for air support, their planes droning like angry hornets ready to sting. This overkill didn't sit well with everyone. Lieutenant General Ando Rikichi, the pragmatic commander overseeing Japanese forces in the region, must have fumed in his Guangzhou headquarters. His intelligence staff, drawing from intercepted radio chatter and local spies as noted in postwar analyses like The Japanese Army in World War II by Gordon L. Rottman, reported that the Chongqing forces in Chaozhou were laughably thin: just the 9th Independent Brigade, a couple of security regiments, and ragtag "self-defense groups" of armed civilians. Why unleash such a sledgehammer on a fly? The mobilization's magnitude even forced a reshuffling of defenses around Guangzhou, pulling resources from the 12th Army's front lines and overburdening the already stretched 18th Division. It was bureaucratic overreach at its finest, a testament to the Imperial Staff's penchant for grand gestures over tactical efficiency. Meanwhile, on the Nationalist side, the winds of war carried whispers of impending doom. The National Revolutionary Army's war histories, such as those compiled in the Zhongguo Kangri Zhanzheng Shi (History of China's War of Resistance Against Japan), note that Chiang Kai-shek's Military Commission had snagged intelligence as early as February 1939 about Japan's plans for a large-scale invasion of Shantou. The efficiency of the Military Command's Second Bureau and the Military Intelligence Bureau was nothing short of astonishing, networks of agents, double agents, and radio intercepts piercing the veil of Japanese secrecy. Even as the convoy slipped out of Penghu, a detailed report outlining operational orders landed on Commander Zhang Fakui's desk, the ink still fresh. Zhang, a battle-hardened strategist whose career spanned the Northern Expedition and beyond , had four months to prepare for what would be dubbed the decisive battle of Chaoshan. Yet, in a move that baffled some contemporaries, he chose not to fortify and defend it tooth and nail. After the Fourth War Zone submitted its opinions, likely heated debates in smoke-filled command posts, Chiang Kai-shek greenlit the plan. By March, the Military Commission issued its strategic policy: when the enemy hit Chaoshan, a sliver of regular troops would team up with civilian armed forces for mobile and guerrilla warfare, grinding down the invaders like sandpaper on steel. The orders specified guerrilla zones in Chaozhou, Jiaxing, and Huizhou, unifying local militias under a banner of "extensive guerrilla warfare" to coordinate with regular army maneuvers, gradually eroding the Japanese thrust. In essence, the 4th War Zone wasn't tasked with holding Chao'an and Shantou at all costs; instead, they'd strike hard during the landing, then let guerrillas harry the occupiers post-capture. It was a doctrine of attrition in a "confined battlefield," honing skills through maneuver and ambush. Remarkably, the fall of these cities was preordained by the Military Commission three months before the Japanese even issued their orders, a strategic feint that echoed ancient Sun Tzu tactics of yielding ground to preserve strength. To execute this, the 4th War Zone birthed the Chao-Jia-Hui Guerrilla Command after meticulous preparation, with General Zou Hong, head of Guangdong's Security Bureau and a no-nonsense administrator known for his anti-smuggling campaigns, taking the helm. In just three months, Zhang Fakui scraped together the Independent 9th Brigade, the 2nd, 4th, and 5th Guangdong Provincial Security Regiments, and the Security Training Regiment. Even with the 9th Army Group lurking nearby, he handed the reins of the Chao-Shan operation to the 12th Army Group's planners. Their March guidelines sketched three lines of resistance from the coast to the mountains, a staged withdrawal that allowed frontline defenders to melt away like ghosts. This blueprint mirrored Chiang Kai-shek's post-Wuhan reassessment, where the loss of that key city in 1938 prompted a shift to protracted warfare. A Xinhua News Agency columnist later summed it up scathingly: "The Chongqing government, having lost its will to resist, colludes with the Japanese and seeks to eliminate the Communists, adopting a policy of passive resistance." This narrative, propagated by Communist sources, dogged Chiang and the National Revolutionary Army for decades, painting them as defeatists even as they bled the Japanese dry through attrition. February 1939 saw Commander Zhang kicking off a reorganization of the 12th Army Group, transforming it from a patchwork force into something resembling a modern army. He could have hunkered down, assigning troops to a desperate defense of Chaoshan, but that would have handed the initiative to the overcautious Japanese General Staff, whose activism often bordered on paranoia. Zhang, with the wisdom of a seasoned general who had navigated the treacherous politics of pre-war China, weighed the scales carefully. His vision? Forge the 12th Army Group into a nimble field army, not squander tens of thousands on a secondary port. Japan's naval and air dominance—evident in the devastation of Shanghai in 1937, meant Guangdong's forces could be pulverized in Shantou just as easily. Losing Chaozhou and Shantou? Acceptable, if it preserved core strength for the long haul. Post-Xinhui, Zhang doubled down on resistance, channeling efforts into live-fire exercises for the 12th Army, turning green recruits into battle-ready soldiers amid the Guangdong hills. The war's trajectory after 1939 would vindicate him: his forces became pivotal in later counteroffensives, proving that a living army trumped dead cities. Opting out of a static defense, Zhang pivoted to guerrilla warfare to bleed the Japanese while clutching strategic initiative. He ordered local governments to whip up coastal guerrilla forces from Chao'an to Huizhou—melding militias, national guards, police, and private armed groups into official folds. These weren't elite shock troops, but in wartime's chaos, they controlled locales effectively, disrupting supply lines and gathering intel. For surprises, he unleashed two mobile units: the 9th Independent Brigade and the 20th Independent Brigade. Formed fresh after the War of Resistance erupted, these brigades shone for their efficiency within the cumbersome Guangdong Army structure. Division-level units were too bulky for spotty communications, so Yu Hanmou's command birthed these independent outfits, staffed with crack officers. The 9th, packing direct-fire artillery for punch, and the 20th, dubbed semi-mechanized for its truck-borne speed, prowled the Chaoshan–Huizhou coast from 1939. Zhang retained their three-regiment setup, naming Hua Zhenzhong and Zhang Shou as commanders, granting them autonomy to command in the field like roving wolves. As the 9th Independent Brigade shifted to Shantou, its 627th Regiment was still reorganizing in Heyuan, a logistical hiccup amid the scramble. Hua Zhenzhong, a commander noted for his tactical flexibility in regional annals, deployed the 625th Regiment and 5th Security Regiment along the coast, with the 626th as reserve in Chao'an. Though the Fourth War Zone had written off Chaoshan, Zhang yearned to showcase Guangdong grit before the pullback. Dawn broke on June 21, 1939, at 4:30 a.m., with Japanese reconnaissance planes slicing through the fog over Shantou, Anbu, and Nanbeigang, ghostly silhouettes against the gray sky. By 5:30, the mist lifted, revealing a nightmare armada: over 40 destroyers and 70–80 landing craft churning toward the coast on multiple vectors, their hulls cutting the waves like knives. The 626th Regiment's 3rd Battalion at Donghushan met the first wave with a hail of fire from six light machine guns, repelling the initial boats in a frenzy of splashes and shouts. But the brigade's long-range guns couldn't stem the tide; Hua focused on key chokepoints, aiming to bloody the invaders rather than obliterate them. By morning, the 3rd Battalion of the 625th Regiment charged into Shantou City, joined by the local police corps digging in amid urban sprawl. Combat raged at Xinjin Port and the airport's fringes, where Nationalist troops traded shots with advancing Japanese under the absent shadow of a Chinese navy. Japanese naval guns, massed offshore, pounded the outskirts like thunder gods in fury. By 2:00 a.m. on the 22nd, Shantou crumpled as defenders' ammo ran dry, the city falling in a haze of smoke and echoes. Before the loss, Hua had positioned the 1st Battalion of the 5th Security Regiment at Anbu, guarding the road to Chao'an. Local lore, preserved in oral histories collected by the Chaozhou Historical Society, recalls Battalion Commander Du Ruo leading from the front, rifle in hand, but Japanese barrages, bolstered by superior firepower—forced a retreat. Post-capture, Tokyo's forces paused to consolidate, unleashing massacres on fleeing civilians in the outskirts. A flotilla of civilian boats, intercepted at sea, became a grim training ground for bayonet drills, a barbarity echoed in survivor testimonies compiled in The Rape of Nanking and Beyond extensions to Guangdong atrocities. With Shantou gone, Hua pivoted to flank defense, orchestrating night raids on Japanese positions around Anbu and Meixi. On June 24th, Major Du Ruo spearheaded an assault into Anbu but fell gravely wounded amid the chaos. Later, the 2nd Battalion of the 626th overran spots near Meixi. A Japanese sea-flanking maneuver targeted Anbu, but Nationalists held at Liulong, sparking nocturnal clashes, grenade volleys, bayonet charges, and hand-to-hand brawls that drained both sides like a slow bleed. June 26th saw the 132nd Brigade lumber toward Chao'an. Hua weighed options: all-out assault or guerrilla fade? He chose to dig in on the outskirts, reserving two companies of the 625th and a special ops battalion in the city. The 27th brought a day-long Japanese onslaught, culminating in Chao'an's fall after fierce rear-guard actions by the 9th Independent Brigade. Evacuations preceded the collapse, with Japanese propaganda banners fluttering falsely, claiming Nationalists had abandoned defense. Yet Hua's call preserved his brigade for future fights; the Japanese claimed an empty prize.

The Japanese operations had yet again plugged up supply leaks into Nationalist China. The fall of Suixian, Zaoyang and Shantou were heavy losses for the Chinese war effort. However the Chinese were also able to exact heavy casualties on the invaders and thwarted their encirclement attempts. China was still in the fight for her life.

3.186 Fall and Rise of China: Battle of Nanchang

Last time we spoke about the Japanese invasion of Hainan. In early 1939, the Sino-Japanese War shifted from pitched battles to a grueling struggle over lifelines and logistics. Japan pursued a southward strategy (Nanshin-ron), aiming to choke Chinese resistance by isolating key railways and airbases. It seized Hainan in February to secure southern airfields and threaten Indochina routes, then targeted Nanchang to cut the vital Zhejiang–Jiangxi Railway, crippling Free China's eastern supply lines. The Japanese used a blended-arms approach: concentrated armor, air support, and amphibious and river operations, focusing on rapid, strategic breakthroughs rather than large-scale frontal assaults. China, though battered, relied on a reconstituted defense around Wuhan and Nanchang, with the Ninth War Zone under Xue Yue delaying Japanese advances and preserving critical corridors south of the Yangtze. The campaign highlighted the war's broader human and political dimensions: massive casualties, forced labor, and internal political fragility within the Kuomintang, even as both sides sought to outlast the other. #186 The Battle of Nanchang 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. For the Second Sino-Japanese War, 1939 marked a transition from broad occupation tactics to a focused, politically driven military strategy aimed at breaking Nationalist cohesion and isolating key nodes. After the January 11, 1938 Imperial Conference, Tokyo framed the China Conflict as a contest of endurance and political attrition: hold occupied territories as strategic assets, push a narrow operational corridor between Anqing, Xinyang, Yuezhou, and Nanchang, and treat the broader east-of-line spaces as pacified. The aim was to deny resources to Chiang Kai-shek's regime while awaiting a more opportune political rupture, instead of pursuing indiscriminate conquest. By October 1938, the tactical center of gravity shifted toward Wuhan and the Yangtze corridor. General Headquarters acknowledged the need to adapt to a protracted war: emphasize political strategy alongside combat operations, bolster a new regime in areas under pressure, and gradually erode Chongqing's moral and material resolve. This shift produced a dual track: reinforce a centralized, secure core while permitting peripheral fronts to be leveraged against Chongqing. In early 1939, Japan sought to consolidate gains through layered defenses and strategic war zones, aiming to blunt Chinese mobilization and disrupt critical logistics. The Ninth War Zone, commanded by Xue Yue, formed a defensive umbrella over Nanchang's northern approaches and the surrounding rail-and-river arteries. China's leadership, notably Chiang Kai-shek, pressed for preemption to seize the initiative: an ambitious plan from Xue Yue to strike by March 24, 1939, to prevent a river-crossing Japanese advance and to pin forces before they could entrench. Japan responded with Operation Ren, targeting the Zhejiang–Jiangxi Railway to sever lines of communication and isolate Nanchang. Okamura Yasuji reorganized heavy weapons into concentrated tank groups, supported by air power, while late-February 1939 movements staged feints and riverine maneuvers to complicate Chinese concentration around Nanchang. The objective was a rapid, surgical seizure of Nanchang to blind the southern airbase network, disrupt the critical rail spine, and push Chinese forces deeper inland, thereby tightening a blockade around southern China. Together, these shifts framed Nanchang not as an isolated objective but as the climactic hinge in a broader strategy of coercive pressure, air-ground mobility, and rail control. The city's fall would represent the culmination of a protracted contest to deny the Nationalist regime its logistical arteries and air superiority, paving the way for further Japanese consolidation and pressure along the Yangtze corridor. In the wake of the Japanese capture of Wuhan in late 1938, the city swiftly transformed into a pivotal stronghold for the Imperial Japanese Army. It became the new base for the 11th Army, occupying the former territories of the National Revolutionary Army's 5th and 9th War Zones. This shift not only consolidated Japanese control over central China but also positioned their forces to launch further offensives, exploiting the region's logistical and geographical advantages. As a key railway hub and the western terminus of the Zhejiang-Hunan Railway, Nanchang served as a vital supply artery connecting the Third and Ninth War Zones of the Nationalist forces. Its airfields further amplified its importance, posing a direct threat to Japanese shipping routes along the Yangtze River. Capturing Nanchang would sever Chinese supply lines, isolate key military districts, and pave the way for deeper incursions into southern China. Faced with this looming threat, the Nationalist government under Chiang Kai-shek moved quickly to reorganize its defenses in the 9th War Zone. General Chen Cheng retained his nominal position as commander in chief, but the actual operational reins were handed to General Xue Yue, a seasoned tactician known for his defensive prowess. This restructuring aimed to streamline command and bolster resistance, yet it was hampered by persistent logistical challenges that rendered many changes ineffective on the ground. As tensions escalated in early 1939, Chinese forces began amassing near Nanchang in preparation for the inevitable clash. Over 200,000 troops from 52 divisions were mobilized, drawing from units across the Hunan-Hubei-Jiangxi Border Area. This region alone housed more than 29 divisions organized into four army groups: the 1st, 19th, 30th, and 32nd. On paper, this formidable assembly included over 16,000 officers and 240,000 enlisted men, representing a significant concentration of Nationalist power. Leading this defensive effort was General Chen Cheng as the overarching commander in chief, with General Xue Yue stepping in as the acting commander to oversee day-to-day operations. Within this structure, the 19th Army Group stood out under the command of General Luo Zhuoying, supported by Lieutenant General Luo Weixong as his chief of staff. Luo Zhuoying, in particular, emerged as a central figure, assuming overall command for much of the ensuing Battle of Nanchang. His leadership would be tested against the relentless advance of the Japanese Eleventh Army, setting the stage for one of the bloodiest engagements of the war. In July 1938, during their offensive against Wuhan, Japanese forces attempted to advance toward Nanchang but were halted by Chinese defenders along the Xiushui River. The Chinese had established strong, fortified positions that effectively barred the Japanese path. The impasse endured for the rest of the year, with both armies locked in a standoff on opposite sides of the river. By March of 1939, the 11th Army led by General Okamura Yasuji, part of the Central China Expeditionary Army of General Hata Shunroku comprised 3 divisions, the 6th, 101st and 106th, roughly 120,000 men supported by 130 tanks and tankettes, 200 pieces of artillery, 30 warships with 50 motor boats, a battalion of SNLF and several air squadrons. On March 12, the Japanese Central China Expeditionary Army issued orders to its directly subordinate 116th Division. This division was commanded to dispatch two key detachments: the Ishihara Detachment and the Murai Detachment, the latter composed meticulously of five battalions drawn from the 119th Brigade. Their mission was to conduct a thorough search along the eastern shore of Poyang Lake, supported by naval vessels that patrolled the waters with menacing precision. The purpose was multifaceted: to safeguard the integrity of land and water transportation routes and to protect the left flank of the main Japanese force as it prepared for larger operations. By March 15, these detachments had advanced without encountering any resistance from the Chinese army, allowing them to conclude their search operation successfully. Following this, they deployed the necessary troops at key points along the route, establishing garrisons that would serve as footholds for future advances. This reconnaissance was no mere stroll; it was a calculated probe into enemy territory, drawing lessons from prior engagements like the grueling Battle of Xuzhou in 1938, where intelligence gathering had proven crucial to Japanese successes. The Japanese soldiers boots sank into the marshy banks of Poyang Lake, China's largest freshwater body, covering over 3,500 square kilometers and teeming with reeds that could hide ambushes. The lack of opposition allowed the Japanese to fortify their positions, setting the stage for the preemptive strikes that would follow. The tempo of battle quickened on March 17, 1939, as the Japanese army launched its preemptive attack, a move designed to seize the initiative and disrupt Chinese preparations. The very next day, on March 18, the Murai Detachment departed from Xingzi aboard warships, navigating the treacherous waters to land near Wucheng, approximately 30 kilometers northeast of Yongxiu. Their objective was to assault the Chinese defenders in this area, but they encountered fierce resistance from the Chinese 32nd Army and other supporting units, turning the landing into a brutal contest of wills. Concurrently, the main forces of the Japanese 101st and 106th Divisions, bolstered by their artillery and tank units, advanced methodically toward the north bank of the Xiushui River. They occupied their respective attack starting points with precision, after which the artillery units began conducting test firings and further reconnaissance to gauge the strength of Chinese defenses. This phase echoed the Japanese tactics employed in the Battle of Shanghai in 1937, where combined arms operations had overwhelmed urban defenses. A Chinese defender's recollection "We watched the enemy approach like a dark cloud, our rifles ready, knowing that the river would soon run red with the blood of brothers." The climax of preparation erupted at exactly 16:30 on March 20, when the Japanese 11th Army issued orders to the commander of the 6th Artillery Brigade. This commander was directed to orchestrate all available artillery to bombard the positions held by the Chinese 49th and 79th Armies on the south bank of the Xiushui River. What ensued was a pre-general offensive artillery barrage that endured for more than three grueling hours, incorporating a large number of poison gas shells, a heinous weapon that flouted international conventions like the Geneva Protocol of 1925. Many defenders' positions were utterly destroyed in this onslaught, and several officers and soldiers, including the valiant Wang Lingyun, commander of the 76th Division, were poisoned by the toxic fumes, suffering agonizing effects that highlighted the barbarity of chemical warfare. At precisely 19:30 that evening, the 106th Division commenced its forced crossing of the Xiushui River at Qiujin. Later, on the night of the 20th, the 101st Division also initiated its crossing north of Tujiabu. The Xiushui River, measuring about 30 meters in width, had swollen by approximately 3 meters due to continual heavy rains, rendering the crossing exceedingly difficult for the Japanese troops who battled against the raging currents. Nevertheless, the flooding had an unintended benefit for the invaders: many defender positions were inundated, and most water obstacles were washed away by the deluge. Leveraging this, the two Japanese divisions broke through the defenders' front lines and executed continuous night attacks, establishing a beachhead that extended 2 kilometers deep by dawn on the 21st. This foothold provided essential cover for Japanese engineers to construct pontoon bridges amid the chaos. At around 8 a.m., the Japanese tank group crossed these pontoon bridges and launched an attack on the Dongshan garrison from the front of the 106th Division, then proceeded to circle around toward Nanchang along the west side of Nanxun Road. Historian Rana Mitter aptly describes such river crossings as "desperate gambles where nature itself became a combatant," underscoring how environmental factors often tipped the scales in Sino-Japanese confrontations.Chiang Kai-shek, monitoring these developments from his command center, would have felt the weight of impending crisis. By 21:30 on March 22, the Japanese vanguard tank group had advanced to Fengxin and successfully occupied the Liaohe Bridge outside the South Gate. The sudden and ferocious tank attack caught the defending troops off guard, preventing them from withdrawing the 38 artillery pieces that had been deployed on the city's outskirts before they were forced into a hasty retreat. On March 23, the Japanese army fully occupied Fengxin. Simultaneously, a portion of the 101st Division launched a frontal assault along Nanxun Road. Under the protective cover of artillery, they crossed the Xiushui River and encountered fierce resistance from the Chinese 32nd Army at Tujiabu, resulting in a prolonged stalemate where neither side could gain a decisive advantage. Following the Japanese launch of their general offensive, the Guilin Headquarters of the National Government Military Commission, under Director Bai Chongxi, urgently ordered all units of the Ninth War Zone to hold their positions firmly on March 21. On the same day, Chiang Kai-shek telegraphed Gu Zhutong, commander-in-chief of the Third War Zone, with specific instructions to immediately transfer the 102nd Division to Nanchang to reinforce the city's defenses, placing it under the command of Luo Zhuoying, commander-in-chief of the 19th Army Group. He also ordered the 16th and 79th Divisions to proceed to Dongxiang and Jinxian, southeast of Nanchang, to guard the southern bank of Poyang Lake and provide support for operations in Nanchang. Simultaneously, he commanded the 19th Army Group to deploy approximately two divisions of its strongest forces to strike key enemy points in the rear, including Mahuiling, Ruichang, Jiujiang, and De'an, with the aim of sabotaging railways and highways, cutting off enemy rear-area transportation, and preventing reinforcements from reaching the front. However, due to poor communication, slow troop movements, and inadequate coordination among units, these ambitious plans were not implemented, and the battlefield situation had already undergone significant changes by the time adjustments could be made. On the 23rd, Chiang Kai-shek came to realize that the Japanese army was resolutely determined to capture Nanchang, and thus he conceived the strategic idea of inflicting heavy casualties on the enemy before potentially abandoning the city. He specifically telegraphed Xue Yue, commander-in-chief of the Ninth War Zone; Luo Zhuoying, commander-in-chief of the 19th Army Group; and Xiong Shihui, chairman of Jiangxi Province, with the following directive: "The key to this battle is not the gain or loss of Nanchang, but inflicting the greatest blow on the enemy. Even if Nanchang falls, all our armies should disregard everything and advance toward the designated targets, and decide on future operational plans in accordance with this policy." This telegram, preserved in wartime archives, exemplifies Chiang's shift toward a war of attrition, a tactic that would define much of China's resistance. On March 25, Chiang Kai-shek again telegraphed Bai Chongxi, Xue Yue, Luo Zhuoying, and Gu Zhutong, providing detailed instructions: "1. The main force of Luo's group should maintain focus on the Hunan-Jiangxi Highway, attack the enemy's right flank, and press them toward the Gan River. It is crucial to avoid having the main force operate with its back to the Gan River. (That is, the main force of the 19th Army Group should be moved to a mobile position west of the Gan River to avoid being forced to the Gan River and facing a decisive battle in an unfavorable situation.) 2. A necessary portion should be used to defend the Nanchang front. If necessary, resistance can be carried out gradually between the Fu and Gan Rivers to cover southern Jiangxi." On the very same day, the Japanese army defeated the 102nd Division, which had been reinforced from the Third War Zone, in engagements west of Nanchang. By March 26, the Japanese army had advanced to the vicinity of Shengmi Street on the left bank of the Gan River. They crossed the river that day, executing a maneuver to outflank Nanchang from the south and simultaneously cut off the Zhejiang-Jiangxi Railway, a critical supply line. The main force of the 101st Division also advanced to Shengmi Street via Wanbu and Huangxi on March 26, crossed the Gan River that evening, and launched a direct attack on Nanchang. Its 101st Brigade, moving along the Nanchang-Xuncheng Railway via Lehua and Jiaoqiao, reached the north bank of the Gan River northwest of Nanchang on the 26th. Upon discovering these Japanese advances, the 19th Army urgently ordered the 32nd Army to withdraw from Tujiabu on the Nanchang-Xuncheng Railway back to Nanchang to join the 102nd Division in defending the city. However, before the 32nd Army had fully withdrawn, the Japanese tank group and the 101st Brigade had already advanced to the Gan River bridges to the west and north of Nanchang, respectively. Although the defending forces managed to destroy the bridges to halt their progress west and north of the Gan River, the Japanese 101st Division had already penetrated into Nanchang from the south. The defenders found themselves outnumbered and with weak firepower compared to the invaders. After engaging in intense street fighting, they suffered heavy casualties and were ultimately ordered to retreat to Jinxian. On March 27, the Japanese 101st Division occupied Nanchang, marking a significant, albeit temporary, victory in their campaign. Eyewitness account "The city fell amid the thunder of guns and the wails of the wounded, a testament to the fragility of urban defenses against mechanized onslaught." Following the capture, on March 28, the Japanese 11th Army was ordered to ensure that the main force of the 101st Division would return to Nanchang and that the 106th Division would retake Fengxin, all in preparation for subsequent operations in Gao'an or areas west of Fengxin. By April 2, the Japanese army had occupied Gao'an City, further consolidating their hold on the region. Meanwhile the fighting extended to Wuning. Wuning is located on the north bank of the Xiushui River, approximately 80 kilometers west of the Nanchang-Jiujiang Railway. This position holds immense strategic importance, backed by the formidable Mufu Mountains, and serves as a key point on the left flank of the Ninth War Zone's defense line in northern Jiangxi. The forces deployed here included the 72nd and 78th Armies of the 30th Army Group, along with the 8th and 73rd Armies of the Hunan-Hubei-Jiangxi Border Advance Army, all positioned along both banks of the Xiushui River under the unified command of Wang Lingji, commander-in-chief of the 30th Army Group. To bolster the defense of Nanchang, the Nationalist Government's Military Commission devised a plan to send a powerful force eastward from Wuning toward Qiujin and De'an, with the intent of harassing the rear and flanks of the enemy advancing south along the Nanchang-Jiujiang Railway and disrupting their transportation networks. After carefully assessing the Chinese deployments and strategic intentions, the Japanese 11th Army also regarded Wuning as a crucial flank in its overall Nanchang campaign. Consequently, they dispatched their 6th Division to Wuning to contain and block the Chinese army, thereby ensuring the safety of its main force's right flank and facilitating the capture of Nanchang. On March 20, while the Japanese army was heavily engaged on the Nanxun Railway front, its 6th Division launched an attack westward along the north bank of the Xiushui River from Ruoxi (situated between Qiujin and Wuning). However, they encountered fierce resistance from the Chinese 73rd and 8th Armies, which resulted in slow and painstaking progress for the attackers. On the afternoon of the 21st, a portion of the 6th Division, under the protective cover of aircraft and artillery, crossed the Xiushui River east of Ruoxi, and the main force directed its assault toward Wuning, while its 36th Brigade targeted Yangzhou Street. The 30th Army Group, tasked with defending Wuning, mounted a tenacious resistance by leveraging the advantageous mountainous terrain, making the Japanese advance extremely difficult. After four days of fierce and unrelenting fighting, the Japanese were still unable to break through the defenders' positions. On the morning of March 23, under continued air and artillery cover, the Japanese army persisted in its fierce attack, repeatedly dropping incendiary and chemical bombs on Chinese positions. The defending forces suffered heavy losses as a result and were compelled to withdraw from Wucheng Town on the 24th, moving farther back to regroup. After occupying Wucheng, the Murai Detachment continued its operations to clear the Gan River and Xiushui River of obstacles and to remove mines that had been laid by the Chinese forces. By the 28th, they had advanced to the vicinity of Xinning Town, which is about 4 kilometers east of Wuning. Its 36th Brigade engaged in fierce fighting with the defending 19th Division at Yangzhou Street on the 24th and successfully captured Jing'an on the 27th; however, due to the conclusion of the Nanchang battle and the fact that its main force was blocked east of Wuning, it quickly returned and redirected its attack toward Wuning. Because the 73rd and 8th Armies had suffered heavy casualties from days of intense fighting, the 30th Army Group ordered the 72nd Army to assume the defense of northeast Wuning. The Japanese 6th Division concentrated its forces for a fierce and coordinated assault, and by the 29th, the defending forces had retreated to the south bank of the Xiushui River, allowing the Japanese army to occupy Wuning. After further intense fighting, by April 5, the Japanese 36th Brigade had advanced to the south bank of the Xiushui River.During this entire period, Chiang Kai-shek repeatedly telegraphed Bai Chongxi and Xue Yue, issuing orders for the 30th Army Group in Wuning and the 31st Army Group in Chongyang and Tongshan (commanded by Tang Enbo) to launch a counteroffensive regardless of the evolving situation in Nanchang. The objective was to flank and attack the enemy's rear, advancing toward Mahuiling, De'an, Yongxiu, and Ruichang on the Nanchang-Xunyi road, to cut off enemy transportation lines and block reinforcements. However, this plan was not implemented due to various logistical and coordination challenges. After the Japanese army captured Nanchang, it maintained a tense standoff with the Third and Ninth War Zones of China along the southeast bank of Poyang Lake to the east, Xiangtang to the south, and Gao'an, Fengxin, and Wuning to the west. The Military Commission of the National Government made a calculated judgment that although the Japanese had occupied Nanchang, they had suffered heavy losses and had not yet had the opportunity to replenish their forces. The defending forces within the city were deemed insufficient, prompting the Commission to decide on launching a counteroffensive while the Japanese army was still in the process of consolidating its position. At the same time, it ordered each war zone to initiate the "April Offensive" (also known as the "Spring Offensive") with the goals of harassing and containing the Japanese army and preventing it from continuing to advance westward toward Changsha. The Military Commission specifically ordered the Ninth War Zone and the Third War Zone to plan and execute a counteroffensive against Nanchang. The forces designated for this operation were planned to include the 1st, 19th, and 30th Army Groups of the Ninth War Zone and the 32nd Army Group of the Third War Zone, totaling about 10 divisions, all under the unified command of Luo Zhuoying, commander-in-chief of the 19th Army Group. On April 17, Chiang Kai-shek telegraphed his detailed "Plan to Conquer Nanchang" to Bai Chongxi, the director of the Guilin Headquarters, and sought his opinion on the matter. The operational strategy outlined was: "First, use the main force to attack the enemy along the Nanchang-Xunyi Railway, effectively cutting off enemy communications, and then use a portion of the force to directly capture Nanchang. The attack is scheduled to begin on April 24th." The main content of its troop deployment was as follows: The 1st Army Group (Commander-in-Chief Gao Yin-huai), the 19th Army Group, and the 74th Army (Commander Yu Ji-shi) were ordered to advance through Fengxin and Dacheng toward the Nanchang-Xunyi Railway between Xiushui and Nanchang, thoroughly disrupting transportation, cutting off enemy reinforcements, and cooperating in the capture of Nanchang; the 49th Army of the 19th Army Group (Commander Liu Duo-quan) was ordered to advance gradually as the general reserve; the 32nd Army Group (Commander-in-Chief Shangguan Yun-xiang) was ordered to attack Nanchang from the east of the Gan River with three divisions, and to organize a regiment to seize Nanchang by surprise; the 30th Army Group (Commander-in-Chief Wang Ling-ji) was ordered to attack Wuning. On April 18, Bai Chongxi replied to Chiang Kai-shek, offering his own suggestions on troop deployment with slight modifications. He emphasized the critical need for a surprise attack and for disrupting and harassing the enemy's transportation and rear areas, as well as cutting off the enemy's communication lines. He also believed that the attack should be brought forward and carried out as soon as possible, at the latest around the 22nd. On April 21, the forces of the Ninth War Zone began their operations in earnest. The 1st Army Group, comprising the 184th Division of the 60th Army and the New 10th Division of the 58th Army, attacked Fengxin, while the New 11th Division of the 58th Army monitored the Japanese forces in Jing'an; the main force of the 74th Army attacked Gao'an, and parts of the 74th Army and the 49th Army crossed the Jinjiang River to the north, attacking Dacheng and Shengmijie. Fierce fighting continued until the 26th, when the Japanese retreated to the areas of Fengxin, Qiuling, and Wanshougong. The 19th Army Group captured strongholds such as Dacheng, Gao'an, and Shengmijie. However, progress thereafter became difficult, and the offensive stalled. Neither army group was able to advance to the Nanchang-Xunyi Railway as originally planned. On April 23, the 32nd Army Group of the Third War Zone, consisting of the 16th and 79th Divisions of the 29th Army, the 5th Reserve Division, and part of the 10th Reserve Division, crossed the Fu River and launched an attack on Nanchang. Fierce fighting persisted until the 26th, when they captured Shichajie (south of Nanchang) and advanced toward the city. On the 27th, the Japanese concentrated the main force of the 101st Division to launch a counterattack. Supported by heavy artillery and air power, they engaged in fierce fighting with the Chinese army in the southeastern and southern areas, repeatedly contesting villages and strongholds. Due to the heavy casualties sustained, Duan Langru, commander of the 79th Division, changed the offensive deployment on the night of April 28 and reported this alteration to the army and army group commanders. The commander-in-chief of the 32nd Army Group, citing unauthorized changes to the plan, reported to the Third War Zone for approval and requested the dismissal of Duan Langru. Eager to capture Nanchang and driven by strategic impatience, Chiang Kai-shek, upon hearing the report, issued a stern order on May 1: Duan Langru was to be executed in front of the army for delaying military operations, He Ping, commander of the 16th Division, was ordered to atone for his crimes by achieving success in battle, and Shangguan Yunxiang was sent to the front to supervise the battle personally, with a strict deadline of May 5 for capturing Nanchang. On May 2, the 102nd Division recaptured Xiangtang and then Shichajie. The 16th Division once captured Shatanbu, but it was subsequently taken back by Japanese reinforcements. Shangguan Yunxiang then committed the 26th Division into the battle. On May 4, they launched another concerted attack. By dusk on the 5th, the 5th Reserve Division had reached the outer perimeter of the city and destroyed the barbed wire defenses, but Japanese firepower was intensely concentrated, causing the division to suffer heavy casualties and rendering it unable to continue the assault. The 152nd Regiment of the 26th Division broke into Xinlong Airport at dawn on the 5th and destroyed three Japanese aircraft. The 155th Regiment broke into the railway station at 9:00 a.m. on the 5th, but was blocked by fierce Japanese firepower and a determined counterattack. On May 5, after Chiang Kai-shek had issued the order to capture Nanchang by May 5, Xue Yue, acting commander of the Ninth War Zone, held the belief that with troops not having been replenished after the defense of Nanchang and with weaponry far inferior to that of the enemy, it was impossible to capture Nanchang within the subjective timeframe set. However, he did not directly dissent to Chiang Kai-shek, and on May 3, he telegraphed Chen Cheng to express his views in detail. He wrote: "Attacks on Nanchang and Fengxin have continued for 11 days since April 23. Because our army's equipment cannot keep pace with the enemy's, and the enemy's heavy weapons, mechanized units, and aircraft can support their ground forces everywhere, it is quite difficult to destroy the enemy's strong positions. Now I have received the Chairman's telegram: our army's operational strategy is to wear down the enemy without being worn down by the enemy, to avoid the enemy's strength and attack their weaknesses, and to achieve a protracted war of resistance. Therefore, this attack on Nanchang is aimed at wearing down the enemy. Under the principle of avoiding the enemy's strength and attacking their weakness, we should lie in ambush in advance and launch a surprise attack from all sides, hoping to recapture Nanchang with the fastest and most agile means. However, the battle has already dragged on; a direct assault is impossible, and striking their weakness is also unattainable. Although the enemy's strength is waning, it is practically impossible to capture Nanchang before May 5. Besides strictly ordering all units to overcome all difficulties and continue the fierce attack at all costs, I intend to politely explain the above situation to Chiang Kai-shek during a telephone conversation." Chen Cheng forwarded Xue Yue's telegram in full to Chiang Kai-shek on May 5. At the time, Bai Chongxi, director of the Guilin Headquarters, also considered the order to capture Nanchang within a limited time to be unrealistic, and on May 5 he telegraphed Chiang Kai-shek and He Yingqin, subtly offering a different suggestion. He stated, "Our army's attack on the enemy must be unexpected to be effective. Now, the enemy in Nanchang is prepared, and our army has launched a ten-day attack and has exerted all its efforts. To consider morale and our highest strategic principles, it is proposed that one-third of our forces continue the siege of Nanchang, while the other two-thirds are reorganized. Outside, we should continue to publicize our aggressive strategy…" The aim of both telegrams was to "turn the enemy's own spear against his shield," hoping Chiang Kai-shek would alter his order to capture Nanchang within a specified time, citing the operational guidance as inconsistent with the broader strategic policy. Upon receiving the telegrams, Chiang Kai-shek also learned of the sacrifice of Commander Chen Anbao and the heavy casualties among the attacking troops. On May 6, the main force of the Japanese 106th Division, supported by aircraft and tanks, launched a pincer attack on the 29th Army in the suburbs of Nanchang and Liantang. By 5 PM, the 29th Army was encircled. Liu Yuqing, commander of the 26th Division, was wounded in the fighting, and army commander Chen Anbao and Xie Beiting, commander of the 156th Regiment, were killed in action. Based on the actual battlefield situation, Xu Zhixun, chief of staff of the 29th Army, and Liu Yuqing, realizing that capturing Nanchang was impossible, decided to break out toward Zhongzhouwei and Shichajie to avoid total annihilation and potential execution by Chiang Kai-shek for failure. A regiment of the 5th Reserve Division, disguised as civilians, had infiltrated the city but was forced to withdraw due to the lack of follow-up support. Finally, on May 9, Chiang Kai-shek issued an order to halt the attack on Nanchang. The Japanese army, having suffered heavy losses themselves, was also unable to mount an effective counterattack, and thus the Battle of Nanchang came to an end, leaving behind a legacy of valor and tragedy. In the Battle of Nanchang, China suffered more than 52,000 casualties, including over 43,000 deaths, while Japan sustained more than 24,000 casualties and over 2,200 deaths. Although the National Army eventually lost Nanchang, the engagement thwarted Japan's plan to crush the main Chinese force.

The Nanchang battle was a decisive Japanese victory, yet the Chinese did manage to halt the Japanese western advance and showcased their perseverance amid a growing strategic stalemate. Supplies were still leaking into Nationalist China, the Japanese would have to continuously find and plug them. The war for China was nowhere near over.
