Vietnamese perspective on Mongolian Invasions

"At that time, the Mongolian became a super power in the world stage. By then, half of the world already felt into the Mongolian hands: Central Asia, Russia, Hungary, Poland, Yugoslavia, Iran... then China. After dominating China, Mongolian look into Vietnam. Then 30,000 troops of Mongolian cavalry -very well known at that time- crossed the border and attacked Vietnam the first time on January 17, 1258. Emperor TRAN THAI TONG -the one who wanted to be a Buddhist monk - now commanded the Vietnamese army to fight back. It took about 2 weeks, the Mongolian was defeated.

Angry over the defeat, the Mongolian took the revenge. The second invasion was well prepared, began on August 1284, with 200,000 strong troops under the command of a Mongolian prince. This time, the commander of Vietnamese army was Emperor TRAN NHAN TONG, also a devout Buddhist. The second invasion was not luckier than the first time. After 6 months that both sides had engaged into the fierce battles, the Mongolian was defeated and there was only a few thousands survived to back home.

For Mongolian, especially Emperor Koubilai, the defeat was so unbelievable and unbearable. It's too shameful for the Mongolian empire, therefore, only two months after the defeat, Koubilai giving the order to mobilize all of his best units, ready to take the revenge. On December 25, 1287, 500,000 Mongolian troops under the command of the same Prince, one more time, crossed the border to invade Viet Nam the third time. Again, Emperor TRAN NHAN TONG led the Vietnamese army to fight back and defeat the Mongolian. This time it took for only 4 months. Like last time, there were only few thousands Mongolian survived to comeback. After the third try, the Mongolian quitting the idea to invade Vietnam. Vietnam then began enjoying the peaceful time for about two centuries."
