Guan Yu defeats Kong Xiu

The carriage was sent off to a safe distance, and then Guan Yu rode at full speed directly at the commander, who set his spear and came to meet him. The two steeds met and the men engaged, but at the first stroke of the green-dragon saber the commander of the gate fell to the earth dead. His troops fled.

“Soldiers, do not flee!” cried Guan Yu. “I killed him because I could do no otherwise. I have nothing against you, but I would ask you to tell the Prime Minister how this thing came to pass, that Kong Xiu wished to kill me, and so I slew him in self defense.” (Romance of the Three Kingdoms, Ch 27).
