The Niños Héroes (in English: Boy Heroes), also known as the Heroic Cadets or Boy Soldiers, were six Mexican teenage military cadets. These cadets 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, during the Mexican–American War. According to legend, in an act of bravery, Juan Escutia wrapped the Mexican national flag around his body and jumped from the top of the castle in order to keep it from falling into the enemy's hands. The Niños Héroes are commemorated by a national holiday on September 13.
