Battle of Changsha (1939)
1939 Chinese victory

The First Battle of Changsha (17 September 1939 – 6 October 1939) was the first of four attempts by Japan to take the city of Changsha, Hunan, during the second Sino-Japanese War. It was the first major battle of the war to fall within the time frame of what is widely considered World War II.

Changsha was the first major city to successfully repel Japanese advances. Retaining the city allowed the Nationalist Chinese forces to prevent the Japanese from consolidating their territories in Southern China. The commander of the city's defense, General Xue Yue, was a graduate of the Republic of China Military Academy and a Chiang Kai-shek loyalist.
