孫傳芳
In October 1925 Guo Songling, a division commander of the Fengtian clique, defected to Feng's Guominjun clique. From November 22 he began to lay siege to Mukden, the capital city of his former Fengtian master. Chiang Kai-shek sought to convince Sun Chuanfang to also defect, though to the Kuomintang. Sun, who was affiliated with Wu Peifu's Zhili clique, was a popular target to woo; having recently fought against Zhang's armies, he was openly unhappy about his enforced alliance with the Fengtian clique. Sun, however, refused and executed Chiang's emissaries. Chiang retaliated in turn by executing Sun's envoys.
