In March 1287, the Yuan dynasty launched their third invasion of Đại Việt. Unlike in the second attack, Prince Hưng Đạo Trần Quốc Tuấn, the commander-in-chief, affirmed that Đại Việt's army could easily break the Yuan military campaign. Indeed, this invasion ended one year later with a disastrous defeat of the Yuan navy at the Battle of Bạch Đằng on March 8, 1288 (in the lunar calendar). Besides Trần Quốc Tuấn, other notable generals of the Trần dynasty during this time included Prince Nhân Huệ Trần Khánh Dư, who destroyed the Yuan navy's logistics convoy at the Battle of Vân Đồn, and General Phạm Ngũ Lão, who was responsible for ambushing Toghan's retreating troops.
