《宋史·列传·卷一百二十八》
当时金军留驻淮东，刘光世害怕敌人锋芒，楚州被围已有一百天，高宗亲自写信五次催促刘光世救援楚州，刘光世竟然不去；只派王德、郦琼率领轻兵前去，自己不时报告战果而已。
时金兵留淮东，光世颇畏其锋，楚州被围已百日，帝手札趣光世援楚者五，竟不行；但遣王德、郦琼将轻兵以出，时奏杀获而已。
At that time, the Jurchen army was stationed in Huai Dong, and Liu Guangshi was afraid of the enemy's sharp weapons. Chuzhou had been under siege for a hundred days, and Emperor Gaozong wrote five letters personally to urge Liu Guangshi to rescue Chuzhou, but Liu Guangshi did not go. He only sent Wang De and Li Qiong to lead a small number of soldiers to defend, and he only reported the results of the war from time to time.
