《资治通鉴·唐纪·唐纪六十二》
河东节度使刘沔、幽州节度使张仲武再三奏称，寒冬季节不可出兵，请求等待明年春天。振武节度使李忠顺独自请求和归义军使李思忠共同进兵，攻击回鹘。
刘沔、张仲武固称盛寒未可进兵，请待岁首，李忠顺独请与李思忠俱进。
Hedong Jiedushi Liu Mian and Youzhou Jiedushi Zhang Zhongwu repeatedly argued that the army should not be deployed during the cold winter season and asked to wait until the next spring. Zhenwu Jiedushi Li Zhongshun requested to join forces with Guiyi Army envoy Li Sizhong to attack the Huigu.
