Юань Шу
When Cao Cao attacked Liu Xiang, Yuan Shu reinforced Kuangting, where the latter was badly defeated. Yuan Shu retreated to defend Fengqiu. Cao Cao subsequently moved to surround the town before Yuan Shu could complete the movement, Yuan Shu fled to Xiangyi (襄邑). Cao Cao pursued to Taishou (太壽) and diverted the waters of the Qu River (渠水) from Xiangyi, cutting off the canal supplying water to the city. After, Yuan Shu fled to Ningling (寧陵) and Cao Cao pursued Yuan Shu's retreat towards Jiujiang (九江). In summer, Cao Cao finally withdrew with his army to Dingtao (定陶).
