《资治通鉴·魏纪·魏纪四》
诸葛瑾听到消息后非常害怕，写信给陆逊说： 主上已经撤军回去，敌军俘得韩扁，会完全知道我们的虚实，而且河水已干，应当火速撤军。 
诸葛瑾闻之甚惧，书与逊云： 大驾已还，贼得韩扁，具知吾阔狭，且水干，宜当急去。 
After hearing the news, Zhuge Jin was very frightened and wrote to Lu Xun "My lord has already withdrawn his army, and the enemy has captured Han Bian, so he will know our real strength and weaknesses. Moreover, the river has dried up, and we should withdraw our army as quickly as possible."
