《史记·七十列传·李将军列传》
走了几十里，李广命令他的骑兵左右散开，两路包抄，他亲自去射杀那三个人，射死了两个，活捉了一个，果然是匈奴的射雕手。
广令其骑张左右翼，而广身自射彼三人者，杀其二人，生得一人，果匈奴射雕者也。
After walking for dozens of miles, Li Guang ordered his cavalry to disperse and outflank the Xiongnu from both sides. He personally went to shoot and kill the three men. He killed two and captured one alive, who was indeed the Xiongnu's archery master.
