南昌起義
In late 1926 He joined the Chinese Communist Party (CCP). In 1927, after the collapse of Wang Jingwei's leftist Kuomintang government in Wuhan and Chiang Kai-shek's suppression of communists, He left the Kuomintang and joined the Communists, commanding the 20th Corps, 1st Column of the Red Army. He and Zhu De planned and led the main force of the Nanchang Uprising in 1927. In the Nanchang Uprising He and Zhu led a combined force of 24,000 men and attempted to seize the city of Nanchang, but they were not able to secure it against the inevitable Kuomintang attempt to retake the city. The campaign suffered from logistical difficulties, and the communists suffered 50% casualties in the two months of fighting. Most of He's soldiers who survived surrendered, deserted, and/or rejoined the KMT. Only 2,000 survivors eventually returned to fight for the Communists in 1928, when Zhu reformed his forces in Hunan.
