Battle of Changsha (1941) Wikipedia
The offensive was carried out by more than 120,000 Japanese troops and much better equipment all around, including supporting naval and air forces. The Chinese forces under the command of General Xue Yue—the 9th Army Group—gathered more than 300,000 with help from the 5th, 6th, and 7th Army Groups, but due to poor intelligence on the Japanese invading forces plus its telegraphic messages having been code-broken by the Japanese army, the defense was on the passive end of the battles.
The invading forces entered Changsha on September 27, 1941. After a major fire which burned down much of the Changsha city, with help from the 6th and the 7th Army Groups, the defensive forces conducted a response that included heavy street fighting in Changsha city. The Chinese armies successfully defended Changsha, retaking the city. Then the 5th and the 6th Army Groups attacked the Japanese forces west of Hankou city in Hubei province which caused the Japanese Army to withdraw from Changsha. The Japanese Army was running low on ammunition and food. Having suffered over 7,000 casualties they retreated.
The battle started when a small Chinese guerrilla force clashed with the Japanese 6th Division in the mountains southeast of Yueyang on 6 September. On the 17th, the Japanese crossed the Xinqiang River (新墙河) at four points and made rapid advances, crossing the Miluo River on 19 September. The main Chinese force avoided confronting the enemy but marched in a parallel fashion, out-flanking the Japanese trail southward. The Japanese also attempted to out-flank and encircle the Chinese. This caused both the Chinese and the Japanese armies to reach the Laodao River (捞刀河) regions for an inevitable battle.
On 27 September, several hundred Japanese troops in plain clothes reached the north gate of Changsha but were unable to sabotage the city defenses, leading to heavy fighting on the 28th. Unable to overcome the defenders, the Japanese began a general retreat back to the Yueyang region on 30 September.
