On 7 April, Chiang and several other KMT leaders held a meeting, during which they proposed that Communist activities were socially and economically disruptive and had to be undone for the Nationalist revolution to proceed. On 12 April, in Shanghai, many Communist members in the KMT were purged through hundreds of arrests and executions on the orders of General Bai Chongxi. The CPC referred to this as the "12 April Incident" or Shanghai Massacre. This incident widened the rift between Chiang and Wang Jingwei, the leader of the left wing faction of the KMT who controlled the city of Wuhan.
