One of the moves that Cao Cao wanted to make in his war against Sun Quan was to intimidate Sun Quan by stationing one of his officers, Xie Qi (謝奇), at Wancheng (皖城; present-day Qianshan County, Anhui) and spread his forces to Qichun County in order to agitate Sun Quan.
[2] Two of Xie Qi's subordinates, Sun Zicai and Song Hao, surrendered to Lü Meng, boosting morale.
[4] Lü Meng's prediction quickly was proven correct,[5] Sun Quan then started to send out his warships onto Cao Cao's army, but a few of their ships were blown off course, but not much.
In a momentum burst, a few other generals of Sun Quan joined Lü Meng in a following assault onto Wancheng and Lujiang.
Zhang Liao, following this withdrawal, stationed his troops at Hefei,[7] where in 215 he played a major role in the Battle of Xiaoyao Ford.
