via Vietnam Plus, 23 January 2020: Nice aerial view of the stakes planted on a former riverbed, related to the Battle of Bach Dang River.
Archaeologists have recently unearthed wooden stakes that are thought to have been planted in a river in the coastal city of Hai Phong to repel Yuan-Mongol invaders’ boats and secure the Bach Dang River victory in 1288 for Dai Viet (then Vietnam).
Researcher Bui Van Hieu from the Vietnam Archaeology Institute said the stakes would have been deployed by Tran Dynasty (1226-1400) fighters as a trap to destroy enemy boats and divert the current.
The historic victory reported in records has been proved by traces of wooden stakes on the river bed found in Yen Giang, Dong Van Muoi and Dong Ma Ngua in the northern province of Quang Ninh.
Recently, traces of the same wooden stakes have been unearthed in Lien Khe commune, Thuy Nguyen district, Hai Phong city.
