The Battle of Taierzhuang () took place during the Second Sino-Japanese War in 1938. It was fought between the armies of the Republic of China and the Empire of Japan at the peak of the Xuzhou Campaign. The battle was the war's first major Chinese victory. The battle was a setback for the Japanese military and its reputation as an invincible force. For Chinese forces, it was a tremendous morale boost.

The battle was characterized by vicious close quarters combat. The cramped conditions of urban warfare neutralized Japanese advantages in cannon and heavy artillery. In these circumstances, the Chinese were able to fight the Japanese as equals. Unlike previous engagements, the Chinese managed to resupply their troops while also preventing the Japanese from doing the same. After two weeks of heavy fighting, the Japanese were in short supply of men and material. The Japanese were then virtually encircled by a Chinese counterattack, and were forced out of Taierzhuang with heavy casualties.

Taierzhuang is located on the eastern bank of the Grand Canal of China and was a frontier garrison northeast of Xuzhou. It was also the terminus of a local branch railway from Lincheng. Xuzhou itself was the junction of the Jinpu railway (Tianjin-Pukou), the Longhai railway (Lanzhou-Lianyungang), and the headquarters of the KMT's 5th War Zone.

Background Political and strategic situation By 1938, the Chinese military had suffered tremendous losses in the campaigns of Shanghai and Nanjing. In particular, its air force and navy had both been virtually wiped out. Nonetheless, China's resolve in resisting the Japanese invasion showed no signs of weakening. On 30 January, the Japanese military high command, after evaluating the situation in China, decided that no new offensive operations should be conducted until August. Emperor Hirohito's stance was even more conservative: he believed that it would take at least a year for the Japanese to solidify their positions in their newly captured territory and consolidate their strength before conducting any further operations. Thus, the Japanese high command decided to wait until 1939 before conducting a swift, aggressive offensive in order to decisively end the war in China.

At the same time, Chiang Kai-shek refused to accept the Japanese terms for surrender. On 20 February, China withdrew its ambassador Xu Shiying from Japan. The next day, Japan followed suit, withdrawing its ambassador Kawagoe Shigeru. Earlier that year, Chiang had also resigned from his post as Premier of the Executive Yuan, in order to fully dedicate his efforts to the war. The respective actions taken by both sides indicated their attitude towards the war: China was now fully committed, while Japan still showed some signs of hesitation.

Military situation Despite Hirohito's declaration that no new offensives would be conducted in 1938, the Japanese forces in China were eager to continue their offensive, with morale reaching a peak following the Fall of Nanjing. The IJN's preferred strategy would have been to continue advancing westwards along the Yangtze River to invade Wuhan.

However, the IJA was reluctant to continue following this approach of following waterways, and instead pursued the Chinese army retreating from the Shanghai-Nanjing theatre, driving northwards into the three provinces of Jiangsu, Shandong and Henan.

A significant proportion of the Chinese forces that withdrew from Shanghai crossed the Yangtze River northwards into the Jiangbei region. During the retreat from Nanjing, many scattered Chinese troops also found themselves drifting down the Yangtze and into Jiangbei. The IJA saw this as an opportunity to pursue and destroy this cluster of disorganized Chinese troops, thus ignoring the IJN's strategy of following the Yangtze westwards.

Throughout December 1937, Rippei Ogisu's 13th Division pursued the fleeing Chinese forces, capturing Jiangdu, Shaobo, and advancing into Anhui to capture Tianchang. Simultaneously, in Northern China, Rensuke Isogai's 10th Division, advanced southwards between Qingcheng and Jiyang to cross the Yellow River, approaching the Jiaoji railway. Gaining access to the railway would enable it to move westwards then southwards to clear the Jinpu railway and join forces with the 13th division at Xuzhou. From there, the combined Japanese forces could attack Wuhan and force the KMT into surrender. The war had thus moved from the 3rd to the 5th War Area.

Armies Chinese Chiang sent his Vice Chief of Staff Bai Chongxi to Xuzhou in January 1938. Li Zongren and Bai were old comrades from the New Guangxi Clique, and had served alongside each other since the Battle of Longtan in the Northern Expedition.

Chiang sent Li the 3rd War Area's 21st Group Army. Also a unit from Guangxi, the 21st was commanded by Liao Lei and consisted of the 7th and 48th Armies. At this time, Sun Zhen's 22nd Group Army, a unit from the Sichuan clique also arrived at the Shanxi-Henan region, only to be rejected by both Yan Xishan (commander of the 2nd War Area and chairman of Shanxi) and Cheng Qian (commander of the 1st War Area and chairman of Henan). Both Yan and Cheng disliked units from Sichuan for their poor discipline, particularly their rampant opium consumption.

Under the command of Sun Zhen, the 22nd Group Army had deployed four of its six divisions to assist the war effort in Northern China. Organized under the 41st and 45th Armies, the contingent began its foot march towards Taiyuan on 1 September, marching for more than 50 days continuously and covering some 1400 kilometers. When they arrived in Shanxi, they were confronted with an icy winter. Despite lacking winter uniforms or even a single map of the province, they immediately engaged the Japanese for 10 days at Yangquan (阳泉), incurring heavy casualties. Desperately low on supplies, they broke into one of the Shanxi clique's supply depots, infuriating Yan Xishan, who expelled them from the province. The 22nd then withdrew westwards into the 1st War Area, only for its commander, Cheng Qian to reject its request for resupplies.

Japanese SouthernCommanded by Rippei Ogisu, the Japanese 13th Division, drove westwards from Nanjing via two columns in early February: the northern column advanced towards Mingguang (明光), while the southern column advanced towards Chuxian . Both columns were checked by Wei Yunsong's 31st Army, which had been tasked with defending the southern section of the Jinpu railway by Li Zongren. Despite facing a completely inferior enemy, the Japanese were unable to make any progress even after more than a month of continuous attacks. The Japanese then deployed armoured and artillery reinforcements from Nanjing. The Chinese responded by withdrawing westwards to the southwestern outskirts of Dingyuan in order to avoid direct confrontation with their reinforced foes.

By this time, Yu Xuezhong's 51st Army had already positioned itself defensively on the northern banks of the Huai River, forming a defensive line between Bengbu and Huaiyuan. The Japanese proceeded to successively capture Mingguang, Dingyuan, and Bengbu before advancing towards Huaiyuan.

However, their supply routes were then intercepted by the Chinese 31st Army, which conducted flanking attacks from the southwest. The Japanese situation was worsened further when the Chinese 7th Army (led by Liao Lei) then arrived at Hefei, reinforcing the 31st Army. Engaged by three Chinese armies simultaneously, the Japanese were trapped south of the Huai River and unable to advance any further despite enjoying complete air superiority and having a complete advantage in firepower.

The Chinese had thus foiled the Japanese plan of advancing their 13th Division northwards along the Jinpu railway and joining forces with Isogai Division (10th Division) to launch a pincer attack on Xuzhou.NortheasternAfter amphibiously landing at Qingdao, the Japanese 5th Division (commanded by Seishiro Itagaki), advanced southwestwards along the Taiwei Highway, spearheaded by its 21st Infantry Brigade. There they faced the Chinese 3rd Group Army, commanded by Pang Bingxun. Despite being designated as a Group Army, Pang's unit only consisted of the 40th Army, which itself only consisted of the 39th Division, a unit from the Northwestern Army. Led by division commander Ma-Fawu, the 39th's five regiments ended up delaying the Japanese advance towards Linyi for over a month. The Japanese captured Ju County on 22 February and pushed towards Linyi on 3 March.

However, they were met by a stiff Chinese counterattack, which checked them at the Taoyuan region. The Japanese then conducted heavy aerial bombardment on the single Chinese division, forcing it to withdraw into Linyi. During this time, Zhang Zizhong's 59th Army, also a Northwestern unit, had moved eastwards from Xuzhou along the Longhai railway, passing Tai’erzhuang before advancing northwards towards Linyi. It crossed the Yi River on 12 March and attacked the Japanese left flank, engaging them from 13 to 18 March, during which the 39th Division managed to push the Japanese out of the Linyi region. Pursued by the Chinese from two directions, the Japanese were forced to withdraw, losing almost two entire battalions in the process. This engagement broke the myth of Japanese invincibility and also humiliated Japanese commander Seishirō Itagaki, even shocking the IJA headquarters. Although the Japanese 5th Division later regrouped and tried again, it had lost the element of surprise. The Japanese defeat at Linyi at the hands of the inferiorly trained and equipped Chinese regional units set the scene for the eventual battle at Tai'erzhuang.NorthernOf the three Japanese divisions driving into the Chinese 5th War Area, the 10th Division, commanded by Rensuke Isogai, was the most successful. Setting out from Hebei, it crossed the Yellow River and moved southwards along the Jinpu railway. With KMT General Han Fuju having ordered his forces to desert their posts, the Japanese successfully captured Zhoucun and moved into Jinan without meeting any resistance at all. The Japanese then advanced southwards along two columns from Tai'an. The eastern column captured Mengyin before pushing westwards to capture Sishui.

The western column advanced south-westwards along the Jinpu railway, capturing Yanzhou, Zouxian, and Jining, before driving north-westwards to capture Wenshang. Chiang Kai-shek then ordered Li Zongren to utilize 'offensive defense', i.e. seizing the initiative to actively attack, instead of passively defending. Thus, Li deployed Sun Zhen's 22nd Group Army to attack Zouxian from the south while Pang Bingxun's 40th Division advanced northwards along the 22nd's left flank to attack Mengyin and Sishui. Sun Tongxuan's 3rd Group Army also advanced from the south, launching a two-pronged attack on the Japanese at Jining. Fighting fiercely from 12 to 25 February, the respectable combat performance of the 12th Corps in particular helped to ameliorate the reputational damage that Han Fuju had otherwise inflicted upon on the Shandong units. The Japanese made some strategic changes as a result of these Chinese counterattacks: they cancelled their original plan of directly advancing westwards from Nanjing to Wuhan, so that more troops could be spared for the push towards Xuzhou.

Battle

Opening shots (March 15 – March 21)

On March 15, the Japanese 10th Division attacked the Chinese 122nd Division centered around Tengxian and Lincheng. Chinese reinforcements from the 85th Army arrived the next day, but were forced back on March 17. The Japanese, with the support of planes, tanks and heavy artillery, broke through the Chinese lines on March 18.

The Chinese remnants, bolstered by the 52nd Army, retreated to the town of Yixian. The Japanese attacked the town, and destroyed an entire Chinese regiment in a fierce 24-hour battle. On March 19, the Japanese began their advance on the walled town of Taierzhuang.
