《宋史·列传·卷一百四十八》
隆兴元年春，诸将领有北伐的意见被报告给皇上，此事下到督府讨论，李椿正奉命到巢州，他立即写奏记给张浚说 ：复仇伐敌，是最合乎天下人心的，此提议不是出自督府而出自诸将口中，况且我们藩篱不坚固，储备不丰裕，将虽多但无才能，士兵弱而且未训练，意见又不统一，即使夺得了土地，未必容易守住。 结果朝廷派兵出征没有成功。
隆兴元年春，诸将有以北讨之议上闻者，事下督府，椿方奉檄至巢，亟奏记浚曰： 复雠伐敌，天下大义，不出督府而出诸将，况藩篱不固，储备不丰，将多而非才，兵弱而未练，议论不定，纵得其地，未易守也。 既而师出无功。
In the spring of the first year of Longxing, several generals' suggestions for the Northern Expedition were reported to the emperor. This matter was passed to the governor's office for discussion. Li Chun was ordered to go to Chaozhou and immediately wrote a memorial to Zhang Jun, saying: "Revenge and attacking the enemy is most in line with the people's hearts but this proposal did not come from the Governor's Office but from the generals. Moreover, our fences are not strong, our reserves are not abundant, our generals are many but have no talent, our soldiers are weak and untrained, and our opinions are not the same. Even if we seize the land, it will not be easy to hold it." As a result, the court sent troops to fight but were unsuccessful.
