《宋史·列传·卷一百二十五》
一百人听到哨声便聚集一起，金军更加难测虚实，整个夜晚自相残杀积尸布满田野，被迫退居老婆湾。
百人者闻吹声即聚，金人益不能测，终夜自战，积尸盈野，退军老婆湾。
One hundred people gathered together when they heard the whistle. The Jin army was even more difficult to measure. The whole night was full of corpses in the field, and they were forced to retreat to Laopo Bay.
