IOTL, Xiang Yu, leader of the state of Chu, ultimately lost the Chu-Han contention to the Han forces led by Liu Bang (later Emperor Han Gaozu). I don't know all the details of the war, but was there any way the Chu forces could have won? I'm thinking not dismissing Fan Zeng, or maybe staying with his army at the ravine where the Han army taunted them into a rash attack (sorry, forgot the name of the battle).
