Xie Xuan vs Zhang Xiu

Xie Xuan commanded the Eastern Jin army against the massive Former Qin invasion led by Fu Jian. Using a feigned retreat and surprise attack, his forces routed the Qin army, securing the survival of the Eastern Jin dynasty and preventing northern conquest of the south.

Following the victory at Fei River, Xie Xuan led campaigns to recover territories in the north. He recaptured several cities and provinces, expanding Eastern Jin control into the Central Plains.

Xie Xuan died of illness at age 45, cutting short his military career. His death was a loss to the Eastern Jin, which faced continued threats from northern states.

Zhang Xiu ambushed Cao Cao's forces at Wancheng after Cao Cao seduced Zhang Xiu's aunt. The surprise attack killed Cao Cao's son Cao Ang, his nephew Cao Anmin, and his general Dian Wei. Zhang Xiu then allied with Liu Biao.

Zhang Xiu surrendered to Cao Cao on the advice of his strategist Jia Xu. Cao Cao accepted his submission, married Zhang Xiu's daughter to his son, and granted him a marquisate. This ended their conflict and strengthened Cao Cao's forces.

Zhang Xiu fought under Cao Cao at the Battle of Guandu against Yuan Shao. His contribution helped Cao Cao secure a decisive victory, which established Cao Cao's dominance over northern China.

Zhang Xiu died of illness during Cao Cao's campaign against the Wuhuan tribes in the north. His death removed a key general from Cao Cao's army, but the campaign succeeded in pacifying the northern frontier.
