《资治通鉴·汉纪·汉纪八》
有一位骑白马的匈奴将领出阵来，监护他的军队，李广上马，和十多个骑兵奔向前去，射死了匈奴的白马将军，又返回来，到达他的百骑阵营中，解下马鞍，命令战士们放开战马，卧地休息。
有白马将出，护其兵；李广上马，与十馀骑奔，射杀白马将而复还，至其骑中解鞍，令士皆纵马卧。
A white-horse Xiongnu general came out to supervise his army. Li Guang mounted a horse and galloped forward with a dozen cavalrymen, shot the Xiongnu white-horse general dead, turned and came back, and reached his own 100-cavalry camp, removed their saddles, and ordered his soldiers to let the warhorses go and lie on the ground to rest.
