Cao Quy pile pile opens a new research direction

Scientists believe that the discovery of the Cao Quy pile pit opens a new research direction on the Bach Dang Giang campaign, which may change the previous perception.

The scientists determined that this was a large and important pile-yard , related to the Bach Bang Giang campaign against the Yuan Mong invaders of the Tran people in 1288, led by Hung Dao Vuong Tran Quoc Tuan.

The pile ground is built by Tran Quoc Tuan in the bed of Da Bac river, at the junction leading to the creek connecting to Gia river, to the mouth of Bach Dang river. Over nearly 1,000 years, alluvial deposits, the flow changed, especially the impact of humans, so the river bed was narrowed and the old pile field now became part of a rich field.

In addition to ironwood stakes, many stakes are made of chrysanthemum and wood . The longest pile is nearly 5 m, shorter than 2 m; Large diameter of 0.5 m, small of 0.2 m. All piles are much better preserved than piles at the Quang Yen pile site (Quang Ninh).

However, archaeologists have not been able to explain how the pile is driven down because the excavation results show that many of the piles are flat.

History professor Le Van Lan said that the Cao Quy pile was discovered, showing that the victory of the Tran army and people in 1288 was "Operation Bach Dang Giang" rather than "Battle of Bach Dang Giang" as per the long-term perception. .

Sharing the same opinion with Professor Lan about the importance of Cao Quy pile pile, Prof. Vu Minh Giang, Vice President of Vietnam Association of Historical Sciences, said that the discovery of Cao Quy pile pile opens a new research direction on the battlefield. Bach Dang Giang translation. It makes the researchers unable to conclude the battle on Quang Yen (Quang Ninh) or Thuy Nguyen (Hai Phong) is important.

Earlier, on December 18, a part of ironwood pile was discovered under mud in three holes in Cao Quy field, Lien Khe commune, Thuy Nguyen district. The piles are driven to a depth of 2.5 m, with a hooked end to place the zipper or tenon in the middle of the body. Each pile has a diameter of 20-50 cm, buried 5-7 m apart. Two samples of piles were assessed by radioactive isotope method Carbon 14 to give results dating from 1270 to 1430.

The third resistance against Nguyen Mong, the Tran army under the command of Hung Dao King Tran Quoc Tuan won. The Dai Viet Book of Historical Records, which chronicles the most prominent battle of Tran Quoc Tuan as Marshal as follows:
