Zhang Ni
Around 227, when the Shu chancellor Zhuge Liang was assembling forces in Hanzhong Commandery in preparation for the first of a series of campaigns against Shu's rival state Wei, local bandits pillaged the villages in Hanzhong, Guanghan and Mianzhu commanderies. Zhang Ni, then holding the rank of an acting Commandant, led troops to deal with the bandits, who scattered and hid in different locations when they heard of Zhang Ni's approach. Zhang Ni could not force them to come out to fight him, so he pretended to offer to extend a "heqin" policy to the bandit chiefs, and then managed to coax them into attending a banquet to celebrate the peace. After the unsuspecting bandit chiefs got drunk, Zhang Ni ordered his men to kill all of them and then sent his troops to hunt down and eliminate the rest. The massacre lasted for about 10 days, after which the area was clear of bandits.
