《百战奇略·第八卷·必战》
不久，雨过天晴，司马懿令部队制作攻城器械，并迅速发起进攻，箭飞如雨，攻势迅猛。城中敌人顿时陷于粮尽的困难境地，饥饿严重以至发生人吃人现象。公孙渊窘急无奈，便派部将王建、柳甫出城乞降，请求解除对襄平城的围困，并表示公孙渊君臣一定自缚前来请罪归附。
既而雨霁，造攻具攻之，矢石如雨，粮尽窘急，人相食，乃使其将王健、柳甫乞降，请解围，当君臣面缚，懿皆斩之。
Soon, after the rain and the sky cleared, Sima Yi ordered his troops to make siege equipment and quickly launched an attack, with arrows flying like rain and a rapid offensive. In an instant, the enemy in the city fell into a difficult situation with no food, and the hunger was so severe that people began to cannibalize each other. Gongsun Yuan was helpless in his embarrassment, so he sent his generals Wang Jian and Liu Fu out of the city to beg for surrender, asking to lift the siege of Xiangping City, and stating that Gongsun Yuan, the lord and his ministers, would definitely come to plead guilty and submit on their own accord.
