Battle of Chapultepec

The Battle of Chapultepec (September 1847) was a U.S. victory over Mexican forces holding Chapultepec Castle west of Mexico City during the Mexican-American War.

The Mexican-American War played a critical role in defining the border between the two nations that remains in place today.

In 1847, knowing that the capture of the Palacio Nacional would greatly disarm the Mexican army, the Marines stormed the enemy fortress during the Battle of Chapultepec.
