《元史·列传·卷二十五》
交战之初，武宗要亲自出战，脱脱拦马谏阻，武宗大怒，挥鞭打脱脱的手，脱脱不退，武宗只得不出战。
师次杭海，进击海都，大破其众，脱脱手斮一士之首，连背胛以献，武宗壮之。
At the beginning of the battle, Emperor Wuzong wanted to go out to fight in person. Tuotuo blocked the horse and stopped him. Emperor Wuzong was furious and whipped Tuotuo's hand. Tuotuo did not retreat, and Emperor Wuzong had to refuse to fight.
