Liu E
In August 221, Liu Bei sent his generals Wu Ban and Feng Xi to attack the Wu positions at the Wu Gorge, which were guarded by Li Yi () and Liu E (). After Wu Ban and Feng Xi achieved success, the Shu army, comprising over 50,000 troops, advanced further to Zigui County. Liu Bei also sent messengers to request for reinforcements from the local tribes in Wuling Commandery (武陵郡). At Zigui, Liu Bei was pleased when he encountered Liao Hua, a former subordinate of Guan Yu. Liao Hua became a prisoner-of-war in Wu after Guan Yu's death but managed to escape and make his way back to Shu. Liu Bei appointed him as the Administrator of Yidu.
