唐繼堯
Feng died in 1919 and the leadership of the Zhili Clique was secured by Cao Kun with the support of Wu Peifu and Sun Chuanfang. Cao and Wu began to agitate against Duan and the Anhui clique and issued circular telegrams denouncing his collaboration with Japan. When they successfully pressured the president to dismiss Duan's key subordinate Gen. Xu Shuzheng, Duan began to prepare for war against the Zhili Clique. At this juncture, Cao Kun and Wu Peifu began to organize a wide-reaching alliance including all opponents of the Anhui clique. In November 1919 Wu Peifu met with representatives of Tang Jiyao and Lu Rongting (warlords of Yunnan and Guangxi, respectively) at Hengyang and signed a treaty titled “Rough Draft of the National Salvation Allied Army” (), forming the base of the anti-Anhui clique alliance that also included Zhang Zuolin's powerful Fengtian clique.
