Peng Yue
Shortly after, as Xiang Yu was retreating eastwards, Liu Bang renounced the treaty and led his forces to attack Western Chu. Liu Bang sent messengers to Han Xin and Peng Yue, requesting for their assistance in forming a three-pronged attack on Xiang Yu, but Han Xin and Peng Yue did not mobilise their troops and Liu Bang was defeated by Xiang Yu at the Battle of Guling. Liu Bang retreated and reinforced his defences, while sending emissaries to Han Xin and Peng Yue, promising to grant them fiefs and titles of vassal kings if they would join him in attacking Western Chu.
