桓玄
Liu Yu sent Liu Yi, He Wuji, and Liu Daogui west to attack Huan Xuan. They quickly defeated Huan Xuan's general He Danzhi () and took Jiang Province (江州, modern Jiangxi and Fujian), and then continued to head toward Jiangling. They encountered Huan Xuan's much larger force at Chenghong Island (), in modern Ezhou, Hubei), and despite the numerical disadvantage, they crushed Huan Xuan's forces. Huan Xuan fled back to Jiangling with Emperor An, while Huan Xuan's brother-in-law Yin Zhongwen () turned against him and took Emperor An's wife Empress Wang Shen'ai and Emperor Mu's wife Empress Dowager He to Jiankang.
