《资治通鉴·唐纪·唐纪五》
追兵惧怕便停止了追击，停一会儿又重新追赶，几次三番，每次追赶上必定有人被杀死，李世民先后射杀了几个人，尉迟敬德杀死十几人，追兵不敢再进逼。
追者惧而止，止而复来，如是再三，每来必有毙者，世民前后射杀数人，敬德杀十许人，追者不敢复逼。
The pursuers were afraid and stopped chasing, and after a while they started chasing again, and after several rounds, every time they caught up, someone was killed. Li Shimin killed several people in succession, and Yuchi Jingde killed a dozen people, and the pursuers did not dare to advance.
