Li Zicheng
After repressing revolts against Qing rule in Hebei and Shandong in the Summer and Fall of 1644, in October of that year Dorgon sent several armies to extirpate Li Zicheng from his Shaanxi stronghold. Qing armies led by Ajige, Dodo, and Shi Tingzhu (石廷柱) won consecutive engagements against Shun forces in Shanxi and Shaanxi, forcing Li Zicheng to leave his Xi'an headquarters in February 1645. Li retreated through several provinces until he was killed in September 1645, either by his own hand or by a self-defense peasant group.
