《资治通鉴·唐纪·唐纪五十四》
卢从史第一个提出讨伐王承宗的策谋，及至朝廷发兵后，卢从史却停留下来，不肯进兵，暗中与王承宗互通计谋，让将士们暗地里在怀中揣着王承宗的行军标记，还抬高草料与粮食的价格，以便破坏度支的军需供应，暗示朝廷任命他为平章事，上奏诬告各道与王承宗勾结，不赞成进兵。宪宗为此甚为忧虑。
卢从史首建伐王承宗之谋，及朝廷兴师，从史逗留不进，阴与承宗通谋，令军士潜怀承宗号；又高刍粟之价以败度支，讽朝廷求平章事，诬奏诸道与贼通，不可进兵，上甚患之。
Lu Congshi was the first to propose a plan to attack Wang Chengzong. When the court sent troops, Lu Congshi stayed behind and refused to advance. He secretly colluded with Wang Chengzong and asked the soldiers to secretly carry Wang Chengzong's march mark in their arms. He also raised the price of hay and food. In order to disrupt the supply of military supplies, and suggested that the imperial court appoint him as Pingzhangshi, he falsely accused the various Daos of colluding with Wang Chengzong and did not approve of sending troops. Xianzong was very worried about this.
