On July 17 Wu Peifu personally commanded the Zhili army's western front, performing a daring maneuver, outflanking the enemy and taking the western zone's Anhui headquarters. He captured the Anhui army's front-line commander-in-chief Qu Tongfeng (曲同丰) and many of his officers, including the 1st Division commander. After taking the town of Zhuozhou, Wu pursued the retreating enemy toward Beijing. With the exception of the 15th Division, the remainder of the Anhui army on the western front was annihilated. On the same day the Fengtian army attacked the Anhui eastern front. Upon learning of the collapse of the western zone, Anhui's eastern commander, chief of staff Gen. Xu Shuzheng, fled Langfang to Beijing, leaving his troops to surrender to the combined might of the Fengtian and Zhili cliques.
