Trần Hưng Đạo (1228–1300; 陳興道) was the Vietnamese military Grand Commander of Thang Long during the Trần Dynasty. Born as Trần Quốc Tuấn (陳國峻), he commanded the Dai Viet (Đại Việt) armies that repelled two major Mongol invasions in the 13th century. His multiple victories over the mighty Mongol Yuan Dynasty under Kublai Khan are considered among the greatest military feats in world history. General Trần Hưng Đạo's military brilliance and prowess is reflected in his many treatises on warfare and he is considered one of the most accomplished generals in history.
During the first stage, the Mongols quickly defeated most of the Đại Việt troops, stationed along the border. Prince Toghan's fleet devastated most of the force of General Trần Khánh Dư in Vân Đồn. Right before that, Prince Ariq-Qaya had led his cavalry to attack and capture Phú Lương and Đại Than, two important border stations in the north of Đại Việt. This ground force later met up with Prince Toghan's fleet in Vân Đồn. King Trần Nhân Tông called back General Trần Khánh Dư for court-martial, but this general delayed his return and regrouped his force in Vân Đồn. The cavalry and fleet of Prince Toghan continue to advance to Thăng Long. Unfortunately, the trailing supply fleet of Prince Toghan, arriving at Vân Đồn right after that, was ambushed and captured by the remaining forces of General Trần Khánh Dư.
This news together with the news that General Trần Hưng Đạo had recaptured Đại Than in the north sent the fast advancing Mongol forces into chaos. Guerrilla tactics by the Vietnamese also started to cause a great deal of casualties to the Mongols. But the Mongols kept advancing to Thăng Long, which was already abandoned by Đại Việt's king. The following battle results were mixed: the Mongols won at Yên Hưng and Long Hưng but lost in the sea of Đại Bàng. Eventually, Prince Toghan decided to withdraw his army: he would lead the ground force through Nội Bàng while his fleet commander, Omar would direct the fleet back through Bạch Đằng River.
The Mongol fleet, however, had no idea of an unconventional trap already set by General Trần Hưng Đạo on Bạch Đằng River. Trần Hưng Đạo, for months before that, had his soldiers and peasants place huge steel-tipped wooden stakes in some waters of Bạch Đằng River. During the retreat of Omar, the Vietnamese used small craft to aggravate and lure the Mongol vessels to those waters, in what first appeared to be a victorious pursuit of the Mongols. As the tide on Bạch Đằng River receded, the Mongol vessels got stuck and sunk by those embedded steel-tipped stakes. The Vietnamese led by Trần Hưng Đạo burned off approximately 400 Mongol vessels and attacked ships on this river. The entire Mongol fleet was destroyed, and Omar, the Mongol fleet admiral was captured and executed.
The ground force of Prince Toghan was more fortunate. They were ambushed along the road through Nội Bàng, but managed to escape back to China by dividing their forces into smaller retreating groups.
It must be noted that Tran Hung Dao achieved his military success with an army largely constituted of poorly equipped volunteers and peasant conscripts against the mighty hordes of the Mongols who were at the apex of their power after conquering most of Asia. His strategic brilliance had contributed much to this success.
Đại Việt's General Trần Hưng Đạo defeated the Mongols in two major campaigns. General Trần Hưng Đạo led an army of poorly equipped volunteers and peasant conscripts against the overstretched forces of the Mongol Empire. This, combined with losses against the Japanese in the Battle of Koan and failed raids into Europe, marked the end of the apex of Mongol power. Trần Hưng Đạo defeated them with inventive military tactics by exploiting their traditional "raiding" style of warfare which relied on lightning-strike cavalry maneuverability. He is famous for arguably pioneering the "hit and run" warfare. Trần Hưng Đạo was a master of strategic geographical war fighting, applying advantageous landscapes to stage battles in places such as dense forests or on waterfronts where enemy cavalry were mostly ineffective.
Most notable was his speech "Hich Tuong Si" (Call of Soldiers/Proclamation to Officers and Troops), addressing his soldiers at the beginning of the Mongol Invasion in 1285.
His advice to Emperor Trần Anh Tôn prior to his death in 1300 served several times as reference for most of Vietnamese in the struggle for independence: "When the enemy advances roaring like fire and wind, it is easy to overcome them. If they use patience like the silkworm nibbling berry leaves without looking for a quick victory and without fleecing people, we need to have not only good generals but also an elaboration of adequate tactics like in a chess game. In any way, the army should be united, having only one heart like father and sons in a family, the people should be treated with humanity so we can guarantee deep roots and durable bases."
He is revered by the Vietnamese people as a national hero. Several temples are dedicated to him. Most major cities in Vietnam have streets named after him.
