《宋史·列传·卷一百一十九》
宗泽认为应该立即会兵李固渡，断绝敌人归路，其他人不同意，宗泽于是独自领兵赶赴李固渡，在路上遇到金兵，宗泽派遣秦光弼、张德进行夹击，大败金兵。
泽言宜急会兵李固渡，断敌归路，众不从，乃自将兵趋渡，道遇北兵，遣秦光弼、张德夹击，大破之。
Zong Ze believed that the troops should join forces at Ligud渡 immediately and cut off the enemy's path of retreat. However, other people disagreed. Zong Ze led his troops to Ligud渡 alone. On the way, he encountered the Jurchen army. Zong Ze sent Qin Guangbi and Zhang De to attack from both sides, and they defeated the Jurchen army in a crushing victory.
