The First Battle of Changsha (17 September 1939 – 6 October 1939; Chinese: 第一次長沙會戰) was the first of four attempts by Japan to take the city of Changsha, Hunan, during the second Sino-Japanese War. Coming two weeks after Germany's invasion of Poland on September 1, it was the first major battle of the war to fall within the time frame of what is widely considered World War II.
