《资治通鉴·后周纪·后周纪五》
北汉军攻城久攻不下，杨廷璋估计他们疲惫困乏没有准备，暗中与李谦溥约定，各招募敢死士兵一百多人深夜偷袭敌营，北汉军队惊慌溃逃，斩首一千多级；北汉军队于是撤退离去。
北汉攻城久不下，廷璋度其疲困无备，潜与谦溥约，各募死士百馀夜袭其营，北汉兵惊溃，斩首千馀级，北汉兵遂解去。
The Northern Han army's siege dragged on and they could not break through. Yang Tingzhang guessed they were exhausted and unprepared. He covertly coordinated with Li Qianpu and each recruited over a hundred death-defying soldiers to sneakily attack the enemy camp in the dead of night. The Northern Han army panicked and fled, losing over a thousand commanders; the Northern Han army then retreated and left.
