《元史·列传·卷九十》
当元军渡江时，宋兵列阵于南岸，还拥有水军准备迎战。布伯在北岸竖炮击宋军，击沉宋军所有的兵船，后来每次战斗，只要用布伯的炮击，都会立功。
时国兵渡江，宋兵陈于南岸，拥舟师迎战，布伯于北岸竖炮以击之，舟悉沉没。后每战用之，皆有功。
When the Yuan army crossed the river, the Song army was lined up on the southern bank and had also assembled a navy to prepare for battle. Bu Bo set up cannons on the northern bank to fire upon the Song army, sinking all their ships. Later, in every battle where Bu Bo’s cannons were used, they would achieve great things.
