《资治通鉴·唐纪·唐纪六十二》
李德裕说： 现在，朝廷征发各道的兵马尚未到前线集中，天德城孤立无援，如果不用这些粮食救济处于饥饿边缘的回鹘，使他们暂且安定下来，那么，万一天德城被回鹘攻陷，谁担当这个罪责！ 
德裕曰： 今征兵未集，天德孤危。倘不以此粮啖饥虏，且使安静，万一天德陷没，咎将谁归！ 
Li Deyu said: Right now, troops have not yet been concentrated at the front, and Tiandu City is isolated and unable to get reinforcements. If we don’t use this food to save the Uighurs and stabilize them, who should bear the responsibility if Tiandu City is conquered by the Uighurs!
