Battle of West Hubei The Battle of West Hubei ( ) , was one of the 22 major engagements between the National Revolutionary Army and Imperial Japanese Army during the Second Sino - Japanese War . It was also one of the four major battles that took place in Hubei . The battle was named the in Japanese , and was also known as “ Operation G ” in Japanese military records . Plan of Operations . The purpose of the operation was to stabilize the Chinese territory under occupation by the Japanese 11th Army under the command of Lieutenant General Isamu Yokoyama by capturing the city of Yichang and to secure control over all water - bourne traffic on the Yangtze River downstream . Much of the river was already under the control of the Japanese , but traffic was subject to frequent attacks by the Chinese , who also attempted to use naval mine s to disrupt shipping . The operation consisted of three phases . The first phase was from 9 – 15 April with elements of the IJA 40th Division , IJA 3rd Division and IJA 17th Independent Combined Brigade advancing from Huarong County and the city of Shishou to the north shore of Dongting Lake and Xanthan Lake . The second phase of the operation began on 5 May , with portions of the IJA 13th Division and 58th Division advancing south from Zhejang and attacking the Chinese 87th Army ( 55th , 43rd and New 22nd Divisions ) . The third phase of the operation started from 18 May with the Japanese advancing as far as the Xiling Gorge . The Chinese made a strong stand at Badong County , as possession of the Xiling Gorge placed the Japanese at the entrance to the Three Gorges of the Yangze River and opened the possibility of a direct advance to Chongqing , the war - time capital of China . Chinese General Chen Cheng ordered the troops of the Chinese 18th Army and Chinese 11th Army to fight to the death to hold their positions , and received air support from the American Fourteenth Air Force . The Chinese then began a counterattack where Japanese forces were weak , and succeeded in cutting off and destroying a portion of the IJA 13th Division , forcing the survivors to retreat to Jingmen . Facing increased Chinese resistance with increased air attacks from the Americans , and having accomplished their goals of controlling river traffic on the Yangtze River and de - mining operations , the Japanese declared the operation to be complete on 29 May . Results . During the course of the operations , the Chinese forces had 30 , 766 casualties with 4 , 279 prisoners , and the loss of numerous artillery pieces and 13 aircraft , against 771 killed and 2 , 746 wounded for the Japanese , of whom 157 were killed and 238 wounded in air attacks . The battle thus resulted in a Japanese tactical victory , with the Chinese losing far more troops , although the Chinese government and Western media at that time reported that the Chinese had scored a major victory . with the Japanese repulsed back to roughly their original positions . Contemporary Western sources played down the operation as per historian Barbara W . Tuchman , who wrote that the " Japanese withdrew without pursuit from what appeared to have been a training and foraging offensive to collect rice and river shipping . " Changjiao massacre . During the time period of the Battle of West Hubei , People ’ s Republic of China historians have claimed that the Changjiao massacre ( ) occurred , during which Japanese troops slaughtered more than 30 , 000 civilians at a factory in the tiny hamlet of Changjiao , northern Hunan over a three day period from 9 – 12 May 1943 . No reference to this event appeared in contemporary Kuomingtang or Western historical sources .
