We learned something new from our visit to the Chapultepec Castle. We learned that North America had invaded the castle in 1847 from this plaque:
This link gives interesting details about battle: Battle of 1847 Below is a photo of the model they displayed about the Battle of Chapultepec.
Also this is from Wikipedia's description of Chapultepec Castle under Independence:
"The United States Marine Corps honors the Battle of Chapultepec and the subsequent occupation of Mexico City through the first line of the "Marines' Hymn," From the Halls of Montezuma. Marine Corps tradition maintains that the red stripe worn on the trousers of officers and noncommissioned officers, and commonly known as the blood stripe commemorates the supposedly high number of Marine NCOs and officers killed storming the castle of Chapultepec in 1847."

"During the battle, six Mexican military cadets refused to fall back when General Bravo finally ordered retreat and fought to the death.:316 These were teniente (lieutenant) Juan de la Barrera and cadets Agustín Melgar, Juan Escutia, Vicente Suárez, Francisco Márquez and Fernando Montes de Oca, all between the ages of 13 and 19. According to legend, the last of the six, Juan Escutia, grabbed the Mexican flag, wrapped it around himself and jumped off the castle point to prevent the flag from falling into enemy hands. In 1967, Gabriel Flores painted a mural depicting "Los Niños Héroes".
"A mural decorates the ceiling of the palace, showing Juan Escutia wrapped in the flag, apparently falling from above. A monument stands in Chapultepec Park commemorating their courage. The cadets are eulogized in Mexican history as Los Niños Héroes, the "Child Heroes" or Heroic Cadets."
Here's the photo we took of the mural on the ceiling at the castle:
