The Niños Héroes (Spanish: [ˈniɲos ˈeɾoes], 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.
Chapultepec Castle was defended by Mexican troops under the command of Nicolás Bravo, including cadets from the military academy. The number of cadets present has been variously given, from 47 to a few hundred. The greatly outnumbered defenders battled General Scott's troops for about two hours before General Bravo ordered retreat, but the six cadets refused to fall back and fought to the death. Legend has it that the last of the six, Juan Escutia, leapt from Chapultepec Castle wrapped in the Mexican flag to prevent the flag from being taken by the enemy. According to the later account of an unidentified US officer, "about a hundred" cadets between the ages of 10 and 16 were among the "crowds" of prisoners taken after the Castle's capture.
The bodies of the six youths were buried on the grounds of Chapultepec Park. On March 5, 1947, a few months before the 100th anniversary of the Battle of Chapultepec, U.S. President Harry S. Truman placed a wreath at the monument and stood for a few moments of silent reverence. Asked by American reporters why he had gone to the monument, Truman said, "Brave men don't belong to any one country. I respect bravery wherever I see it." In 1947 their remains were found and identified and, on 27 September 1952, were re-interred at the Monument to the Heroic Cadets in Chapultepec.
