《资治通鉴·唐纪·唐纪三》
正当梁师都与梁礼战斗激烈时，段德操用轻骑打起很多旗帜，从背后突然袭击梁师都，梁师都的军队溃败，唐军追逐逃敌走了二百里，攻克了梁师都的魏州，俘虏二千多名男女。
师都与礼战方酣，德操以轻骑多张旗帜，掩击其后，师都军溃；逐北二百余里，破其魏州，虏男女二千馀口。
Just as Liang Shidu and Liang Li were fighting fiercely, Duan Decao used light cavalry to raise many flags and suddenly attacked Liang Shidu from behind. Liang Shidu's army was defeated, and the Tang army chased the fleeing enemy for 200 li, captured Liang Shidu's Weizhou, and captured more than 2,000 men and women.
