The imminent Mongol’s invasion was a matter of life and death for Đại Việt. It was a testing time for everyone from the court to the common people. Traitors and heroes revealed themselves. One such hero, and arguably the most famous was Commander-in-chief of the armies (Quốc công Tiết chế) Trần Hưng Đạo.
Prince Trần Hưng Đạo always put the country above everything else. He made peace with his sworn enemy so they could work together for the cause. He promoted talented people regardless of their backgrounds. He was not only a military mastermind but also a literary talent with masterpieces well-revered in history.
