The Niños Héroes (in English: Boy Heroes), also known as the Heroic Cadets or Boy Soldiers, were six teenage military cadets who died defending Mexico at Mexico City's Chapultepec Castle (then serving as the Mexican army's military academy) from invading U.S. forces in the 13 September 1847 Battle of Chapultepec.
Their commanders, General Nicolás Bravo and General José Mariano Monterde, had ordered them to fall back from Chapultepec but the cadets did not; instead, they resisted the invaders until they were killed, with accounts maintaining that the last survivor leapt from Chapultepec Castle wrapped in the Mexican flag to prevent it from being taken by the enemy.
