naval route and quickly deployed heavy unconventional traps of steel-tipped wooden stakes unseen during high tides along the Bạch Đằng River bed. When Omar ordered the Mongol fleet to retreat from the river, the Viet deployed smaller and more maneuverable vessels into agitating and luring the Mongol vessels into the riverside where the booby traps were waiting while it was still high tide. As the river tide on Bạch Đằng River receded, the Mongol vessels were stuck and sunk by the embedded steel-tipped stakes. Under the presence of the Emperor Emeritus Thánh Tông and Emperor Nhân Tông, the Viet forces led by the Prince of Hưng Đạo burned down an estimated 400 large Mongol vessels and captured the remaining naval crew along the river. The entire Mongol fleet was destroyed and the Mongol fleet admiral Omar was captured. The cavalry force of Prince Toghan was more fortunate. They were ambushed along the road through Nội Bàng, but his remaining force managed to escape back to China by dividing their forces into smaller retreating groups but most were captured or killed in skirmishes on the way back to the border frontier. Death In 1300 AD, he fell ill and died of natural causes at the age of 73. His body was cremated and his ashes were dispersed under his favorite oak tree he planted in his royal family estate near Thăng Long in accordance to his will. The Viet intended to bury him in a lavish royal mausoleum and official ceremony upon his death, but he declined in favour of a simplistic private ceremony. For his military brilliance in defending Đại Việt during his lifetime, the Emperor posthumously bestowed Trần Hưng Đạo the title of Hưng Đạo Đại Vương (Grand Prince Hưng Đạo).
