张献忠
In early 1646 Dorgon sent two expeditions to Sichuan to try to destroy Zhang Xianzhong's Great Xi dynasty regime: the first expedition did not reach Sichuan because it was caught up against remnants; the second one, under the direction of Hooge (the son of Hong Taiji who had lost the succession struggle of 1643) reached Sichuan in October 1646. Hearing that a Qing army led by a major general was approaching, Zhang Xianzhong fled toward Shaanxi, splitting his troops into four divisions that were ordered to act independently if something were to happen to him. Before leaving, he ordered a massacre of the population of his capital Chengdu.
