Meanwhile, Liu Bang had mustered an army of about 560,000 with support from the kings who surrendered to him. In the eighth month, Chu's capital, Pengcheng (彭城; present-day Xuzhou, Jiangsu), fell to a coalition force led by Liu Bang. When Xiang Yu received news that Liu Bang had occupied Pengcheng, he led 30,000 troops to retake Pengcheng. Liu Bang was caught off guard and his army suffered heavy casualties and his family members were captured by Chu forces. After the battle, Han lost its territorial gains in Chu and the support of its allies.
