Cao Cao first orders the two generals who earlier surrendered to him, Song Xian and Wei Xu, to fight. In fact this is only to get rid of them ’by the use of another man’s sword’; he lets Yan Liang kill them. Thereafter he sends the four generals, Xu Chu, Xiaohou Dun, Zhang Liao and Xu Huang to take turns in fighting Yan Liang. However, they are not able to defeat the enemy and have to withdraw to the hill.
