Hong Chengchou
Upon seeing enemy's advance, Hong Taiji ordered his troops to set an ambush along the enemy's retreat, while also seizing their logistic supply. His troops then slaughtered every single retreating enemy. Hong Chengchou decided to conduct a desperate attack. His subordinates disagreed with his plan; some argued that they should retreat to Ningyuan and resupply the troops. Wang Pu and some generals decided to retreat without orders upon hearing that Hong Taiji himself was leading the army, and were horribly slaughtered by Hong Taiji. Only 50,000 survived the battle.
