Cao Hong
Cao Hong appears as a minor character in the historical novel "Romance of the Three Kingdoms", which romanticises the events before and during the Three Kingdoms period. In chapter 58, Cao Hong had a rather prominent role at the Battle of Tong Pass between Cao Cao and a coalition of northwestern warlords led by Ma Chao and Han Sui. Cao Cao had instructed Cao Hong to guard Tong Pass for ten days at all costs and not leave his post. However, after hearing taunts from the enemy for nine days, Cao Hong finally gave in to his anger and led his troops out of the pass to engage the enemy. He not only lost the battle but also lost the pass as well. Cao Cao was so angry with Cao Hong that he wanted to execute him for disobeying orders, but his subordinates stopped him. Later on, Cao Hong redeemed himself by risking his life to save Cao Cao, who was fleeing from the battlefield after being defeated by Ma Chao. Cao Hong blocked Ma Chao from chasing Cao Cao and duelled with him for about 100 rounds until Ma gave up and retreated. Cao Cao pardoned Cao Hong for his earlier mistake after taking into consideration how Cao Hong saved his life. There is no mention of these incidents in historical records.
