《元史·列传·卷八》
兀良合台遣阿术与大纳、玉龙帖木儿为前军，自与四王为后军前后夹击，大破宋军。围攻潭州城，月余不下。这时，世祖已渡江驻鄂州，遣也里蒙古领兵二千来援。
时世祖已渡江驻鄂州，遣也里蒙古领兵二千人来援，且加劳问。
Wulianghetai sent Asud, Dana, and Yulong Tiemuer as the vanguard, while he and the four princes were the rear army. They attacked the Song troops front and back, and defeated them in a great battle. They laid siege to Tan Prefecture city, but could not conquer it for over a month. At this time, Shizu had already crossed the river and stationed himself at Ezhou. He sent Yiligenggu to lead 2,000 soldiers to their aid.
