Pressed by the Zhili clique and the Anhui clique, Feng Guozhang ordered Cao Kun to make war again on Hunan province in January and defeated the Constitutional Protection Army in April. However, after capturing Hunan, the Zhili commander Wu Peifu halted the attack on Guangdong and Guangxi province and had a peaceful settlement with the south in July. Xu Shichang also advocated peace negotiation when he was inaugurated as the president in October, which led to the end of the war.
