Xu Huang
Cao Cao later sent Xu Huang to lead another army to reinforce Cao Ren at Fancheng. Xu Huang broke through Guan Yu's encirclement and routed Guan Yu's forces on the battlefield, thus lifting the siege on Fancheng. Guan Yu withdrew his forces after seeing that he could not capture Fancheng. The "Shu Ji" recorded an incident about Xu Huang encountering Guan Yu on the battlefield. Xu Huang was previously a close friend of Guan Yu. They often chatted about other things apart from military affairs. When they met again at Fancheng, Xu Huang gave an order to his men: "Whoever takes Guan Yu's head will be rewarded with 1,000 "jin" of gold." A shocked Guan Yu asked Xu Huang, "Brother, what are you talking about?" Xu Huang replied, "This is an affair of the state."
