《宋史·列传·卷一百二十五》
敌人果然极力进攻第二道防线，众将中有人请求另选险要地形守御，吴璘激奋地说： 两军刚刚交锋而退走，这是不战而败，我估计敌人不久就要撤走，诸君只管忍耐。 擂鼓换旗，连日血战。
敌果极力攻第二隘，诸将有请别择形胜以守者，璘奋曰： 兵方交而退，是不战而走也，吾度此敌去不久矣，诸君第忍之。 震鼓易帜，血战连日。
As expected, the enemy launched a fierce attack on the second line of defense. Some of the generals asked to select a more dangerous terrain to defend. Wu Lin was excited and said: "The two armies have just fought and retreated. This is a defeat without a fight. I estimate that the enemy will retreat soon. You just need to be patient." Beat the drums and change the flags, fighting bloody battles for days.
