In 219, Sun Quan broke the Sun–Liu alliance and ordered his general Lü Meng to lead troops to seize Liu Bei's territories in southern Jing Province, which were guarded by Liu Bei's general Guan Yu, who was away at the Battle of Fancheng at the time. Zhuge Jin participated in the invasion, which turned out successful. Guan Yu was eventually captured and executed by Sun Quan's forces. Lü Meng died of illness a few months after the victory. In recognition of Zhuge Jin's contributions during the campaign, Sun Quan enfeoffed him as the Marquis of Xuancheng () and appointed him as General Who Pacifies the South () to replace Lü Meng as the Administrator () of Nan Commandery (南郡; around present-day Jingzhou, Hubei), the former headquarters of Liu Bei's territories in Jing Province. Zhuge Jin was stationed at Gong'an County, one of the key counties in Nan Commandery.
