《元史·列传·卷九》
蒙古军元帅到来时，伏兵突然出击，元帅坐骑被绊倒。钤部以自己的马让元帅骑上杀出，自己骑着那匹被绊倒的马断后。蒙军反攻取胜。后来太祖问钤部 ：你在生死存亡关头，而把马让与别人，是为了什么？ 
进兵围肃州，守者乃钤部之兄，惧城破害及其家，先以为请。
When the Generalissimo of Mongol army arrived, the ambush troops attacked suddenly and the Generalissimo's mount was tripped. Qian Bu let the Generalissimo ride on his own horse and killed his way out, while he himself rode on the tripped horse to cover the rear. The Mongol army fought back and won. Later, Emperor Taizu asked Qian Bu, "When you were facing a moment of life and death, why did you let your horse be ridden by someone else?"
