Xu Huang
During the Battle of Fancheng general Xu Huang of Cao Wei was sent to oppose Guan Yu at Fancheng District. Knowing that most of his enemy's soldiers were composed of new recruits without training, Xu Huang did not go into battle straight away but camped behind the enemy to impose a deterrent effect. Meanwhile, he instructed his subordinates Xu Shang (徐商) and Lü Jian (呂建) to oversee the digging of trenches around the nearby enemy stronghold of Yancheng (偃城) to deceive the enemy into thinking that it was trying to cut off supplies into Yancheng. The deception worked, with the position being abandoned, which yielded Xu Huang a foothold on the battlefield. By then, a total of twelve camps had been gathered under the flag of Xu Huang. With the strengthened army, Xu Huang finally unleashed an attack on Guan Yu's camp. The enemy encirclement had five camps and so Xu Huang spread news that he was planning to attack the main camp. He secretly attacked the other four side camps instead. When Guan Yu saw that the four side camps had been destroyed, he personally led 5,000 horsemen to meet the attackers but was eventually outmatched. Many of his soldiers were forced into the nearby Han River and drowned. The siege on Fancheng was then lifted.
