The Bạch Đằng River has been the site of three important battles in Vietnamese history: •
the battle of 938 where
Ngô Quyền defeated an attack by the
Southern Han, resulting in Vietnamese independence. •
the battle of 981 where
Lê Đại Hành defeated the
Song dynasty. •
the battle of 1288, where general
Trần Hưng Đạo employed the tactics used in 938 to drive out the
Mongol invaders. In each of these three battles, stakes in the Bạch Đằng river were used as defensive obstacles. The first time was in 938, as part of
Ngô Quyền's battle strategy. Archaeologists discovered several of these ancient stakes. == References ==
