In 1845, the U.S. launched the Mexican-American War to seize Mexican lands. In September 1847, U.S. Marines and Army troops fought Mexican forces defending Mexico City. In the Battle of Chapultepec, the Americans captured Chapultepec Castle, a historic site also known as the Halls of Montezuma. The victory effectively ended the war.
In the early 1800s, the U.S. stood up to the Barbary States in North Africa that demanded protection payments for U.S. shipping. In 1805, Marine Lieutenant Presley O’Bannon and eight Marines led a force of mercenaries on a 500-mile trek across the desert. Their surprise attack on the city of Derna, on “the shores of Tripoli,” helped bring an end to the conflict.
In 1942, the Commander of the Marine Corps changed “On the land as on the sea” to the current wording, to reflect the addition of air power.
When the U.S. goes to war, the Marines are usually the first troops thrown into battle.
The Marines played a key role in recapturing Pacific Islands from the Japanese during World War II.
Marines believe they are the toughest branch of the U.S. Armed Forces. They sometimes tease their brothers and sisters in the Army, Navy, and Air Force about how Marines always get to the action first—perhaps even in heaven.
Today, U.S. Marines serve as guards at 149 U.S. embassies around the world.
