《资治通鉴·唐纪·唐纪五十六》
不久，李师道上表陈述军中情形，说是将士们不肯让他交送人质与割让土地。宪宗大怒，决心讨伐李师道。
既而师道表言军情，不听纳质割地，上怒，决意讨之。
Not long afterwards, Li Shidao presented an official document explaining the situation in his army, saying that the soldiers were not willing to have him hand over hostages and cede territory. Emperor Xianzong was greatly angered and determined that he would attack Li Shidao.
