Background
The battle
King You ordered his men to light the beacon tower, and put his minister Guo Shifu in charge of his infantry and Guogong in charge of his chariots and sent them ahead to hold on the enemy. Seeing his numerical disadvantage, Guo Shifu ordered Guogong to tease the enemies and ordered his own regiment to run back to the capital. Guogong was left alone and desperately led his 200 chariots to try to stop the attack, but failed and was killed. Upon seeing that not a single ally would come to his aid, Duke Huan of Zheng, King You's uncle, summoned his own guard and merged it with the remnants of the royal army, called along all the court ministers and their families and fled the capital with the King through the east gate.

The forces of Shen refused to persecute the king, so the Quanrong did it alone. King You's refugees were fleeing hastily eastwards, but the mounted units of the Quanrong began to approach them quickly and surround them from the sides. King You could already see the fort of Mount Li in the horizon when his fellows' wives and children tired out and could follow no longer. Standing already on the foothills of Mount Li, the Zhou people stopped and fell under heavy attack. Duke Huan was slain and King You tried to form up his men, but they were soon annihilated - king, soldier, woman and child alike. Baosi was taken as trophy for the Quanrong leader.Aftermath
