Battle of West Hunan

The Battle of West Hunan (Chinese: 湘西會戰), also known as the Battle of Xuefeng Mountains (Chinese: 雪峰山戰役) and the Zhijiang Campaign (Chinese: 芷江戰役), was the Japanese invasion of west Hunan and the subsequent Allied counterattack that occurred between 6 April and 7 June 1945, during the last months of the Second Sino-Japanese War. Japanese strategic aims for this campaign were to seize Chinese airfields and secure railroads in West Hunan, and to achieve a decisive victory that their depleted land forces needed.

This campaign, if successful, would also have allowed Japan to attack Sichuan and eventually the Chinese wartime capital Chongqing. Although Japan was able to make initial headways, Chinese forces with air support from the Americans were able to turn the tide and forced the Japanese into a rout, recovering a substantial amount of lost ground.

This was the last major Japanese offensive, and the last of 22 major battles during the war to involve more than 100,000 troops. Concurrently, the Chinese managed to repel a Japanese offensive in Henan and Hubei and launched a successful attack on Japanese forces in Guangxi, turning the course of the war sharply in China's favor even as they prepared to launch a full-scale counterattack across South China.
