3.200 Fall and Rise of China: The Battle of Yaoyi
Last time we spoke about the battle of West Suiyuan. The Ma Clique, Muslim warlords controlling Northwest China, led by Ma Hongkui and Ma Hongbin, rebuffed Japanese overtures to ally, citing historical grievances like the 1900 invasion. Driven by patriotism, they aligned with the Nationalists, reorganizing forces into the 17th Army Group. In 1938, Ma Hongbin commanded West Suiyuan defenses, building fortifications in harsh desert and mountain terrain, blending cavalry tactics with modern training despite equipment shortages. In January 1940, Japanese and puppet troops advanced from Baotou, occupying Wuyuan and Linhe. Chinese forces, including Fu Zuoyi's 35th Army and Ma's 81st Army, employed guerrilla and mobile warfare. A major counterattack in March recaptured Wuyuan, killing Lt. Gen. Mizukawa and thousands, forcing Japanese retreat. Through ambushes and night raids, the Chinese recovered territories, securing Soviet aid routes and the Shaanxi-Gansu-Ningxia region. Over 2,000 Ningxia soldiers perished, their sacrifices underscoring peripheral fronts' role in national resistance.   #200 The battle of Yaoyi Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

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

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