《资治通鉴·晋纪·晋纪三十九》
北魏国主拓跋嗣听说后，派遣叔孙建、公孙表从河内向枋头进军，又带兵渡过黄河，在滑台城下杀掉尉建，把他的尸体投入黄河，并向王仲德的部下诘问为什么入侵进犯，王仲德派司马竺和之上前回答说： 刘太尉派遣征虏将军王仲德从黄河进军洛阳，去清扫晋室的祖先陵墓，并不敢向魏国发动进攻。
魏主嗣闻之，遣叔孙建、公孙表自河内向枋头，因引兵济河，斩尉建于城下，投尸于河。呼仲德军人，问以侵寇之状。仲德使司马竺和之对曰： 刘太尉使王征虏自河入洛，清扫山陵，非敢为寇于魏也。
When the Lord of Northern Wei, Tuoba Si, heard this, he dispatched Shusun Jian and Gongsun Biao to lead an advance from Henan towards Fangtou, and he also led his army across the Yellow River and killed Wei Jian beneath the walls of Huatai, throwing his corpse into the river.  He then questioned Wang Zhongde's subordinates as to why they had invaded his country.  Wang Zhongde sent Sima Zhuzhi to reply: "Liu Yu, the Imperial Protector, has dispatched General Wang Zhongde to cross the Yellow River and lead an advance on Luoyang in order to clean the tombs of his ancestors.  We have no desire to attack the Wei."
