Duan created a provisional legislature on July 30, the Beiyang government's last assembly. A constitutional drafting commission was also held from August to December but its draft was never accepted as warfare broke out after Fengtian clique general Guo Songling defected to Feng Yuxiang's Guominjun in November, sparking the Anti-Fengtian War. Wu Peifu made an alliance with Zhang against Feng in revenge for the coup. Guo was killed on December 24 and fighting went so badly against the Guominjun, Feng resigned and moved to the Soviet Union but was recalled by his officers in a few months. When the tide turned against the Guominjun, Duan restored the office of premier to shift responsibilities away from himself. The March 18 Massacre of protesters in Beijing led to Duan's downfall. Under heavy pressure, Duan held a special session of the provisional legislature that passed a resolution condemning the massacre. It did not stop Guominjun soldiers from disarming Duan's guards and forcing the Chief Executive to flee to a diplomatic legation the next month. When Zhang's troops retook the capital weeks later, he refused to restore Duan whom he saw as a treacherous double-dealing opportunist. The capital suffered heavily during the initial occupation as Zhang and Wu's troops raped and pillaged the city's inhabitants.
