赤壁之戰
In 208, Xu Huang followed Cao Cao to pacify Jing Province (covering present-day Hubei and Hunan), and participated in the Battle of Red Cliffs in the winter of 208–209. When Cao Cao retreated north after his defeat at Red Cliffs, Xu Huang was ordered to stay behind with Cao Ren in Jiangling County to resist attacks by Sun Quan's forces.
