Battle of Chapultepec

The Battle of Chapultepec took place between U.S. troops and Mexican forces holding the strategically located Chapultepec Castle on the outskirts of Mexico City on September 13, 1847 during the Mexican–American War. The castle was built atop a 200-foot (61 m) hill in 1783, and in 1833 it was converted into a military academy and a gunpowder storage facility. The hill was surrounded by a wall 1,600 yards long.
