彭越
In 203 BC, while Xiang Yu was retreating eastward, Liu Bang, acting on the advice of Zhang Liang and Chen Ping, renounced the Treaty of Hong Canal and ordered an attack on Western Chu. He also requested assistance from Han Xin and Peng Yue to attack Xiang Yu simultaneously from three directions. However, Han Xin and Peng Yue did not mobilise their troops and Liu Bang was defeated by Xiang Yu at Guling (固陵; south of present-day Taikang County, Zhoukou, Henan), and was forced to retreat and reinforce his defences. At the same time, he sent messengers to meet Han Xin and Peng Yue again, and promised to give them land and titles if they joined him in attacking Xiang Yu, and they finally agreed.
