Battle of Wuhan

The Battle of Wuhan was a Japanese campaign of several months in the Second Sino-JapaneseWar, fought from June to October 1938 for possession of the temporary Chinese capital of Wuhan (then Hankou) against the National Revolutionary Army.

Background

The Second Sino-Japanese War, which began in July 1937, had initially brought the Japanese rapid successes in northeast China as well as against the then capital Nanjing and against Shanghai in the year of the war. The Chinese seat of government was then temporarily relocated to Wuhan in central China's Hubei province.

After the fall of Xuzhou in May 1938, the Japanese military leadership began to draw up concrete plans for a quick end to the war. At a cabinet meeting in July, the decision was made to attack the provisional Chinese capital of Wuhan and overthrow the Kuomintang government there. A simultaneous attack on Guangzhou (Canton) was intended to demonstrate to the Chinese that the Japanese military had the power to attack at any point and that further resistance was futile.

After the end of the Battle of Xuzhou, the Japanese had initially advanced further west along the Longhai Railway to take possession of Zhengzhou, the next important railway junction on the way to Wuhan. Here the Longhai Railway crosses the north-south railway line from Beijing to Wuhan. After reaching Kaifeng, some 70 kilometers from Zhengzhou, and threatening to continue their advance, Chiang Kai-shek, on the advice of Chen Guofu, ordered the destruction of the YellowRiver dams at Huayuankou in early June. The resulting floods affected three Chinese provinces (Henan, Anhui, and Jiangsu) and killed up to one million residents. The measure was justified on the grounds that it would avert an imminent threat to Wuhan. In fact, the capture of the city was only delayed for several months. In this way, the Japanese were prevented from advancing south along the Peking-Hankou railway. They chose instead to attack further south, in the Yangtze River valley. Here the action of the land troops could be supported by warships.

Preparations

The Japanese 2nd Army was withdrawn from operations at Zhengzhou and moved to Hefei. It was to advance north of the Yangtze River overland through the Dabie Shan area to reach the Zhengzhou-Hankou Railway north of Wuhan. The Chinese defenders, consisting of the troops of the 9th Military Region (General Chen Cheng) and the troops of the 5th Military Region (General Li Zongren) who had escaped from Xuzhou, numbered an estimated 800,000 men. South of the Yangtze River in southern Anhui Province and in northern Jiangxi Province, troops of the 3rd Military Region also opposed the Japanese.

The Battle of Wuhan was initiated on May 31, 1938, with an air battle over the city. In July and August the bombardment increased and finally led to the destruction of Chiang Kai-shek's headquarters. The German military advisors in China under Alexander von Falkenhausen left the city in early July.

The Japanese 11th Army was regrouped in early July from troops of the Central China Expeditionary Army; it was to advance farther south along the Yangtze River. By mid-July, the Japanese had about ten divisions, most of which were split into two armies (11th and 2nd Armies) for the attack on Wuhan. In total, this amounted to about 350,000 men, who received support from about 500 aircraft:

History

Operations of the 2nd Army

The Japanese 2nd Army opened its offensive in August with an attack on Lu'an. In mid-September it reached Shangcheng and Huangchuan in southern Henan Province, and on October 10 it reached the railway line to Wuhan at Xinyang. From there it turned south toward Yingshan on the Hubei-Anhui border, which it reached in late October. By this time, Wuhan had already fallen to the troops operating in the Yangtze River valley.

Operations of the 11th Army

The 11th Army had begun their offensive on June 12 with attacks on Anqing. The city fell into their hands after only one day, and they gained access to an airfield here. In the last week of June, the heavily fortified Chinese position at Madang, which the Japanese had bombarded from the river with their warships and covered with poison gas, fell. Then, in late July, the important railway junction and river port of Jiujiang farther upriver, defended by 80,000 men under Generals Xue Yue and Zhang Fakui, fell to the Japanese after five days of fighting. There was a nervous tension among the Chinese defenders of Wuhan in the face of the unstoppable Japanese advance. Among the population, there was fear of a repetition of events like those that followed the capture of Nanjing, as repeated on a smaller scale in Jiujiang. A particularly hot summer and the humid river climate led to numerous casualties on both sides from diseases such as malaria and dysentery.

In late August, the 11th Army attacked along the shore of Lake Poyang and toward Yichang, capturing Ruichang. The Chinese soldiers stubbornly defended their positions despite the incessant Japanese bombardment and counterattacked as they did at Huangmei. The Japanese 106th Division was badly battered in the Battle of Wanjialing, which lasted until after the fall of Wuhan. It took the Japanese a full three weeks to gain 15 kilometers of space in September. The 106th Division was trapped in the Lushan Cauldron, and two more divisions, the 27th and 9th, had to be brought up to relieve those still able to fight, numbering about 1000. The fortress of Tianjiazhen held out for two weeks before it was captured by the Japanese, again by the use of poison gas. Although the Japanese army was victorious in terms of the entire operation, it suffered a Pyrrhic victory, suffering almost 30% casualties (over 100,000 men). In October, the two Japanese divisions operating furthest south succeeded in cutting the railway from Wuhan to Guangzhou (Canton). This sealed the city's fate. The Japanese 9th Division was able to break through the defenses of the Chinese 53rd and 32nd Corps and advanced into the Heshengqiao area south of Wuchang on October 24. The city of Wuhan, threatened from three sides, surrendered on October 25, four days after Guangzhou in southern China.
