The Battle of Shouchun (寿春の戦い, rōmaji: Jushun no Tatakai) or Campaign against Yuan Shu was fought between the allied forces under Cao Cao, Sun Ce, and Liu Bei and the forces of the Zhong Dynasty led by Yuan Shu. After having declared himself emperor, Cao Cao issued an edict to the other eastern warlords to destroy Yuan Shu. Lu Bu, who was initially part of the alliance, later betrayed it to side with Yuan Shu.
