宋元之际出现了众多叛宋降元的将领,蜀中名将刘整是其中一员。刘整入元以后,战功卓著,在攻克襄樊之战及淮西等战场都发挥了关键作用,加速了灭宋进程。刘整在仕元生涯中,与蒙古将领矛盾重重,其立功心切的愿望与不如意的仕元境遇相冲突,最终导致其在宋元战争最后关头功未成而身先死。对于刘整个案的考察,有助于认识宋元之际降将的境遇问题。 Song and Yuan dynasties appeared on many rebel Song Yuanzheng generals, famous Shu Liu Shu is one of them. After Liu entered the Yuan Dynasty, he made outstanding achievements and played a key role in the battle over Xiangfan and the battlefields such as Huai Xi, accelerating the process of eliminating Song. During his official career, Liu Zheng contradicted with Mongolian generals and his desire for meritorious service was in conflict with the disappointment of the Shi Yuan Yuan situation, eventually leading him to die at the last minute of the Song-Yuan War. The investigation of Liu’s case will help us understand the realities of the decline of the Song and Yuan Dynasties.
