《元史·本纪·卷七》
十九日，右卫亲军都指挥使忽都等进言 ：五河的城堡已经修筑完成，只是居住的房屋还没有修好，所有的木材和砖瓦都出在宋朝境内，请允许我们率领精锐的兵卒分几路前去夺取。 
庚辰，右卫亲军都指挥使忽都等言： 五河城堡已成，唯庐舍未完，凡材甓皆出宋境，请率精兵分道抄掠。 
On the 19th, you wei qinjun, du zhihui shi Hudu and others made a petition, saying that the castle of Wuhe had been built, but the residences had not yet been repaired. The timber and bricks were all in Song territory. They asked to lead an elite force to attack in several routes to capture them.
