Cheng Pu
Liu Biao died that year and his son Liu Zong surrendered to Cao Cao. As Liu Bei and Liu Qi fled south, Cao Cao requested Sun Quan's support, but Sun Quan decided to resist the northern encroachment instead and sent his generals Zhou Yu and Cheng Pu to support Liu Bei's cohort. Despite Cao Cao's overwhelming numerical superiority, his forces failed to cross the Changjiang and were defeated at the Battle of Red Cliff by an attack of fire ships from Sun Quan's officer Huang Gai. Cao Ren managed to hold onto Jiangling for another year before retreating north.
