Since its somewhat confused beginnings in November 1775 when the Second Continental Congress almost absentmindedly authorized two battalions of American marines, the U.S. Marine Corps has participated in all the nation's wars from the American Revolution through Desert Storm. This compact yet complete study focuses on the big wars but never slights events in between: the little wars, campaigns, punitive expeditions, showings of the flag, protection of American lives and property, and humanitarian missions that help define the corps.
