Peng Chong (). Heeding Wang Hong's advice, Zhang Bu also refused to recognize Liu Yong's son Liu Yu (). Defeat and surrender In 28, Liu Xiu began his offensive against Zhang Bu. The imperial army under Chen Jun () quickly conquered the western part of Taishan and defeated Zhang Bu in a battle at Ying. Later, the Han general Geng Yan helped in the conquest of Taishan. The Han army then focused on eliminating Liu Yu. In 29, after Liu Yu's defeat, a Han army was assembled under Geng Yan to invade Zhang Bu's territory. Geng Yan crossed the Yellow River at Pingyuan Commandery and destroyed three of Zhang's armies placed at his flank. Zhang Bu retreated but when he counterattacked, was decisively destroyed after a two-day battle. Zhang Bu fled to Beihai and joined the warlord Su Mao (). The Han sent envoys to both Zhang and Su, urging them to kill the other and surrender. Zhang Bu was the first to act: he decapitated Su Mao and surrendered with his three brothers and Wang Hong. As promised, he received his marquisate, and he moved with his family and brothers to Luoyang. Death In 32, while Emperor Guangwu was away in the west, Zhang Bu took his family and tried to escape to his former territory with his brothers. Chen Jun, now Administrator of Langya, intercepted them and killed everyone. References Han dynasty people 32 deaths
