在前205年的彭城之战中写给老婆的情书反复回响的爱意
在汉高帝二年（前205年）的春天，彭城之战如同一场震撼的爱情故事——写给老婆的情书：反复回响的悲欢。项羽以三万精兵，在今江苏省徐州市周边击败了刘邦的数十万大军，这一胜利成为了中国历史上著名的少数胜多数的大战例。
项羽在鸿门宴中摆出盛宴，却让刘邦借机逃脱，随后项羽率领楚军向西进发。在进入咸阳之后，他下令屠城，并命令英布将楚义帝杀死于长江之中。当时，刘邦正处于危急之际，在洛阳集合了汉军与五诸侯兵共56万人，以复仇为名东征讨伐项羽。他攻占了彭城，此时有彭越带领三万人加入汉军。这场战斗中，汉军取得了巨大的胜利，但在庆祝酒宴上却疏忽防备。项羽得知彭城失陷后，即刻率领精锐3万人从鲁（今山东曲阜）南下，与胡陵（今山东鱼台东南）会师，然后转至萧县（今安徽萧县西北），第二天清晨突然袭击汉军，将其逼至谷、泗、睢水地区，大破敌方，将十余万汉军压迫到河流旁，被淹死者不计其数，“睢水为之不流”，河水被阻断。此役后，楚军俘获了刘邦的父亲太公、母亲刘媪和夫人吕雉。刘邦则受困于彭城西侧，只剩短兵器可用，当他试图突围时，一阵强风 suddenly swept through, shrouding the sky in darkness. Liu Bang and his followers, including his son Liu Ying and daughter Lady Lu, managed to escape with a small group of cavalry to safety in the nearby town of Xiaoyi.
This battle left Han's army severely weakened, with many of their allies defecting to Chu. As a result, Liu Bang was forced to retreat and regroup at the city of Xinyang (now part of Henan province). The war between Liu Bang and Xiang Yu would continue for another year before it reached its final conclusion.
