《宋史·列传·卷一百三十四》
刘豫僭叛，按理必须将他消灭，臣以为应降敕榜，明告刘豫僭逆的罪行，晓谕江北地区民众，这也就是兵家所说的伐谋伐交。 
刘豫僣叛，理必灭之，谓宜降敕榜，明著豫僣逆之罪，晓谕江北士民，此亦兵家所谓伐谋伐交者。 
Liu Yu has committed treason and rebellion, according to common sense, he must be eliminated, my humble opinion is that we should publicly issue edicts and announcements, clearly stating Liu Yu’s treasonous crimes, clearly informing the people north of the Yangtze River of this, and this is also what military strategists refer to as “attacking plans and attacking connections”.
