In the third lunar month of 1287, the Yuan dynasty launched their third invasion of Đại Việt. This time, unlike the second invasion, commander-in-chief Prince Hưng Đạo (Trần Quốc Tuấn) assured the Emperor that Đại Việt's army could easily break the Yuan military campaign. After occupying and looting the capital, Toghan decided to retreat with the forward troops. This invasion was indeed ended one year later by a disastrous defeat of the Yuan navy at the Battle of Bạch Đằng on the eighth day of the third lunar month, 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 the Yuan navy at the Battle of Vân Đồn, and general Phạm Ngũ Lão, who took charge of ambushing prince Toghan's retreating troops. After the destruction of the Mongol navy, both the Đại Việt and Champa decided to accept the nominal supremacy of the Yuan dynasty and serve as tributary states in order to avoid further conflicts.
