《百战奇略·第一卷·步战》
晋军乘机擂鼓交战，李存审急趋敌军阵后，亲率事先部署在那里的步兵发起突袭，契丹军队大败亏输，狼狈逃窜，从北山口败走。
存勖乃趋后阵，起而乘之，契丹遂大败，席卷其众，自北山口遁去。
The Jin army took the opportunity to beat drums and engage in battle. Li Cunxu rushed to the enemy's rear, personally leading the infantry deployed there to launch a surprise attack. The Khitan army was badly defeated and fled in disarray, fleeing from the Beigukou.
