Lord Xinling of Wei vs Yuan Shao

Lord Xinling (Wuji) stole the commander's seal from King Anxi of Wei to mobilize Wei troops to relieve the siege of Handan. This unauthorized action saved Zhao from Qin conquest but caused a rift with the Wei king, forcing Lord Xinling into exile.

Lord Xinling, commanding a coalition of five states (Wei, Zhao, Han, Chu, Yan), defeated Qin forces at the Battle of Hewai. This victory pushed Qin back and temporarily restored the balance of power in the Warring States.

Yuan Shao's forces clashed with Gongsun Zan's elite cavalry at Jieqiao. Despite being outnumbered, Yuan Shao's infantry, using crossbows and shields, repelled the charge and secured a tactical victory, solidifying his control over northern Hebei.

After years of war, Yuan Shao defeated his rival Gongsun Zan at the Battle of Yijing, conquering the four provinces of Ji, Qing, You, and Bing. This made him the most powerful warlord in northern China, commanding a vast territory and army.

Yuan Shao led a massive army south against his rival Cao Cao. At Guandu, Cao Cao's smaller force launched a surprise attack on Yuan Shao's supply depot at Wuchao, burning it. Yuan Shao's army collapsed, and he was decisively defeated, losing his strategic advantage.

Yuan Shao died in Ye city, reportedly from illness and frustration following his defeat at Guandu. His death triggered a succession struggle between his sons Yuan Tan and Yuan Shang, which further weakened his faction and allowed Cao Cao to conquer the north.
