《宋史·列传·卷四十二》
丁谓遂马上把部队分开，使士兵沿着黄河岸执旗帜，互相攻击打斗，呼喊声传闻到百里外，契丹兵惊惧退去。
遂立部分，使并河执旗帜，击刁斗，呼声闻百余里，契丹遂引去。
Ding Wei immediately divided the troops, and ordered the soldiers to carry flags along the bank of the Yellow River, attacking and fighting each other. The shouts and cries could be heard a hundred miles away, and the Liao soldiers were terrified and retreated.
