夏侯渊
One night in February or March 219, Liu Bei set fire to the barbed fences around Xiahou Yuan's camp, so Xiahou Yuan sent Zhang He to defend the eastern part of the camp while he personally led a lightly armed force to guard the south. Zhang He attacked Liu Bei when the latter taunted him, but he failed to overcome the enemy. Xiahou Yuan then sent a fraction of his own troops to help Zhang He. Liu Bei's general Huang Zhong launched a fierce assault on Xiahou Yuan even though his men had less battle experience than Xiahou Yuan's troops. Xiahou Yuan was killed in action.
