《史记·十二本纪·项羽本纪》
四月，汉军都已进入彭城，搜掠财物珍宝和美女，天天设筵会饮，项王向西进发，到达萧县，早晨攻击汉军，向东进发，到达彭城，中午，把汉军打得大败。
四月，汉皆已入彭城，收其货宝美人，日置酒高会。项王乃西从萧，晨击汉军而东，至彭城，日中，大破汉军。
In April, all Han armed forces had entered Pengcheng, looted wealth, valuables and women, banqueting daily. Xiang Yu led his forces westward to Xiaoxian, attacked Han forces at dawn, and advanced eastward to Pengcheng, crushing them by noon.
