《宋史·列传·卷二百三十五》
朝廷正计划换统帅，刘王卓在盱眙很久，一向想担任统帅；又看见李全的势力稍稍孤单，就认为可建立功名，派镇江副都统彭忄乇到京城去替他说好话，刘王卓自称： 我一向镇抚镇江，三万人讨贼足够用，况且得到四总管的支持，讨贼是有余力的。 朝廷相信了他，彭忄乇也向往取代刘王卓，对刘王卓极力奉承和怂恿。
朝廷方谋易帅，刘琸久在盱眙，雅意建阃；又见贼势稍孤，意功名可立，使镇江副都统彭忄乇延誉京师，自谓： 素抚镇江，三万人足用，且得四总管欢心，讨贼有余力。 朝廷信之，忄乇亦垂涎代琸，从臾尤力。
The court is planning to replace the commander. Liu Wangzhuo has been in Xuyi for a long time and has always wanted to be the commander; Seeing that Li Quan's power is a little lonely, he believes that he can build meritorious deeds, and sends Peng Xin, the deputy commander of Zhenjiang, to the capital to speak good things for him. Liu Wangzhuo said himself: "I have always been comforting Zhenjiang, and 30,000 people are enough to fight the thieves. Besides, with the support of the four chief governors, there is more than enough strength to fight the thieves." The court trusted him, and Peng Xinu also wanted to replace Liu Wangzhuo, so he vigorously flattered and encouraged Liu Wangzhuo.
