The Battle of Bạch Đằng was a decisive naval battle during the third Mongol invasion of Vietnam between Đại Việt commanded by Commander-in-Chief Prince Trần Quốc Tuấn (Prince Hưng Đạo), and the fleet of the Yuan dynasty, commanded by Admirals Omar and Fan Yi on the Bạch Đằng River (today Quảng Ninh province), which Prince Hưng Đạo staged an ambush that destroyed the Yuan fleet, capturing its general, ending Kublai’s intention to conquer Dai Viet and Champa. The battle was a tactical masterpiece of the same stature as a previous battle of Bạch Đằng that occurred in 938 and is considered as one of the greatest victories in Vietnamese military history.
