The CCP continued supporting the Wuhan KMT government, but on 15 July 1927 the Wuhan government expelled all communists from the KMT. The CCP reacted by founding the Workers' and Peasants' Red Army of China, better known as the Red Army, to battle the KMT. A battalion led by General Zhu De was ordered to take the city of Nanchang on 1 August 1927 in what became known as the Nanchang uprising; initially successful, they were forced into retreat after five days, marching south to Shantou, and from there being driven into the wilderness of Fujian. Mao Zedong was appointed commander-in-chief of the Red Army, and led four regiments against Changsha in the Autumn Harvest Uprising, hoping to spark peasant uprisings across Hunan. His plan was to attack the KMT-held city from three directions on 9 September, but the Fourth Regiment deserted to the KMT cause, attacking the Third Regiment. Mao's army made it to Changsha, but could not take it; by 15 September, he accepted defeat, with 1,000 survivors marching east to the Jinggang Mountains of Jiangxi.
