The Second Mongol invasion of Vietnam saw one of the most notable confrontations between the Trần dynasty and the Mongol Empire, which aimed to expand its influence throughout Southeast Asia. In the face of this overwhelming threat, Prince Trần Quang Khải assumed leadership of the Vietnamese forces at the crucial battle site of Chuong Duong. The battle unfolded in an environment of heightened military tension as the Mongols sought to exert their dominance by invading Vietnam's northern territories. The Vietnamese army, having studied the patterns and tactics of the invaders, prepared an elaborate defense leveraging the geography of the region to their advantage.

On the fateful day, the Vietnamese strategically positioned themselves along the banks of the Red River at Chuong Duong, attempting to draw the Mongols into a vulnerable position. As the Mongol ships approached, the Vietnamese launched a surprise attack, utilizing their knowledge of local waterways and employing small boats for rapid movement. This tactic allowed them to inflict substantial damage on the Mongol naval fleet, which was unprepared for the ferocity of the counterattack.

The outcome not only eliminated a significant portion of the Mongolian naval power but also had lasting implications for the Trần dynasty’s defense strategies against future incursions. The victory bolstered the morale of the Vietnamese people and served as a rallying point for continued resistance against foreign invaders, further solidifying the Trần dynasty's legacy in Vietnamese history.
