Bạch Đằng River

The Bạch Đằng River (Vietnamese: Sông Bạch Đằng; also called Bạch Đằng Giang, from 白藤江) is a river in northern Vietnam, located near Hạ Long Bay. It flows through the Yên Hưng District of Quảng Ninh Province as well as the Thủy Nguyên District of Haiphong.

The Bạch Đằng River has been the site of three important battles in Vietnamese history: in 938 resulting in Vietnamese independence, in 981, and in 1288, where General Trần Hưng Đạo employed tactics used in 938 to drive out Mongol invaders.
