Surprised at Baima
Before Guandu, Yan Liang was ordered to besiege Baima; Cao Cao, on Xun You’s plan of feinting at one place to strike another, made a false attack on Yanjin to draw off Yuan’s army, then wheeled back to surprise Baima. Guan Yu, temporarily attached to Cao’s camp, spotted Yan Liang’s canopy, charged his horse into the host of ten thousand, cut Yan Liang down before the lines and took his head, and none of Yuan’s troops could stand against him — the Records reads "none of Shao’s generals could withstand him, and so the siege of Baima was lifted," the most solid feat of arms Guan Yu holds in the histories.
