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