《旧五代史·后晋·少帝纪三》
二十四日，相州上奏，契丹抽兵后撤，那里乡村逃避贼寇的老百姓，已经被打发派遣回各自的家乡经营耕种。开始，少帝因不适初愈，不能亲率军旅出征，紧接着张从恩、马全节相继奏报贼兵充斥，恒州杜威奏告形势危急，少帝说 ：这群贼寇不平定，实难安寝，当率众一战，以救朔方百姓，如果迟疑不决，苟且偷安，那么大河以北，就会沦为寇贼的土地了。

On the 24th, Xiangzhou reported that after the Qidan troops withdrew the people who had fled from the countryside to escape the rebels had been sent back to their homes to farm. At first, the young emperor had not recovered from his illness enough to lead the troops in person, but then Zhang Congen and Ma Quanjie reported that the rebels were everywhere, and Du Wei of Hengzhou said that the situation was critical. The young emperor said, "We cannot rest peacefully until these rebels are defeated. We should send troops to save the people of the northern frontier. If we hesitate and seek peace at any cost, everything north of the Yellow River will become rebel territory." He ordered the generals to muster their troops and formulate a plan for the campaign. On the 24th, the young emperor issued an edict to lead the campaign in person. On February 1, he arrived at Huazhou.
