《南史·本纪·卷一》
十八日，大军驻扎在左里，即将开战，武帝挥动令旗，令旗的旗竿折断，旗子沉入水中，众人都很恐惧，武帝笑着说： 过去的覆舟战役也是这样，今日的胜利是必定无疑的了。 
丙申，大军次左里，将战，帝麾之，麾竿折，幡沈于水，衆咸惧，帝笑曰： 昔覆舟之役亦如此，今胜必矣。 
On the 18th day, the army was stationed in Zuoli, about to go into battle. Emperor Wu waved the command flag, but its shaft snapped and the flag fell into the water. Everybody was terrified, but Emperor Wu said with a laugh, “This is like the battle of Fuchuan in the past; today’s victory is assured!”
