Xiangyang, the strongest fortress of the Song Dynasty, had fallen. As a result, Yuan forces were free to conquer the rest of southern China. Everywhere else Yuan went, Song fortresses fell like sand castles, due to the counterweight trebuchets and later, cannons.

Many people agree that the fall of Xiangyang essentially marked the end of the Song Dynasty. For example, Paul K. Davis wrote, "Mongol victory broke the southern Sung dynasty, leading to the establishment of the Yüan dynasty." For the six years that Yuan sieged Xiangyang, Song were unable to regroup and strike back at Yuan with their resources in the south. In fact, they could not even get much reinforcements and supplies to Xiangyang, to support the hard-working defense there.
