張遼
The Battle of Xiaoyao Ford, also known as the Battle of Leisure Ford, Battle of Hefei, and Hefei Campaign, was fought between the warlords Cao Cao and Sun Quan between 214 and 215 in the late Eastern Han dynasty. The two contending sides were fighting for control over a strategic fortress at Hefei, which was defended by Cao Cao's general Zhang Liao. Towards the end of the campaign, Zhang Liao made use of force concentration and launched a sneak counteroffensive on Sun Quan at Leisure Ford, where Sun only had 1,000 soldiers with him at the time. Amidst the chaos, Sun Quan barely escaped capture with the aid of his general Ling Tong. This action raised Zhang Liao to primacy among Cao Cao's generals.
