Zhang He
In anticipation of a prolonged war, Zhang He led his army to Dangqu Commandery (宕渠郡; around present-day Qu County, Sichuan) in order to relocate the population of Ba Commandery (巴郡; present-day Chongqing and eastern Sichuan) to Hanzhong Commandery. Meanwhile, Liu Bei appointed Zhang Fei as the Administrator of Baxi Commandery () and ordered him to take over the region. Zhang Fei and Zhang He faced each other for 50 days, which concluded with a victory for the former following a surprise attack on the latter. Narrowly escaping, Zhang He retreated to Nanzheng County on foot, and the Ba region became part of Liu Bei's territory.
