Peng Yue
In 203 BC, Liu Bang came to an armistice with Xiang Yu, known as the Treaty of Hong Canal, which divided China into west and east under their respective domains. Shortly after, Liu Bang renounced the treaty and led an attack on Xiang Yu's forces, which were retreating east. Liu Bang sent messengers to request assistance from Han Xin and Peng Yue in forming a three-pronged attack on Western Chu, but Han Xin and Peng Yue did not mobilise their troops, and Liu Bang was defeated by Xiang Yu in the Battle of Guling.
