白藤江
The Battle of Bạch Đằng (; , Chữ nôm: 陣白藤) was one of the greatest victories in Vietnamese military history. It was a navy battle between Đại Việt, commanded by Commander-in-Chief Prince Trần Hưng Đạo, and the invading army of the Yuan dynasty, commanded by general Omar Khan on the Bạch Đằng River (today Quảng Ninh province). The Battle of Bạch Đằng was the last confrontation between Đại Việt and the Yuan dynasty. The battle took place at the Bạch Đằng River, near Ha Long Bay in present-day northern Vietnam. The battle was a tactical masterpiece of the same stature as the other battle at Bach Dang River.
