On November 10, 1775, the Continental Congress resolved to raise two battalions of Marines to serve as landing forces for the new American Navy, provide security for ships and crews, and protect officers from insurrection. During the Spanish-American War, Marines led U.S. forces ashore and soon served overseas to protect American lives and interests. In World War I, the 5th and 6th Regiments earned a reputation as fierce fighters and were called "Devil Dogs" for their action at Belleau Wood, France, in 1918. After the war, the Marines developed the doctrine, equipment, and organization for amphibious warfare, then proved those capabilities during World War II by taking part in nearly every battle in the Pacific Theater. By 1945, the Marine Corps had grown to more than 475,000 personnel with six divisions and five air wings, and Marine expeditionary forces later served in every U.S. military action worldwide to protect freedom and democracy. Aboard the North Carolina, an 85-man Marine Detachment in the Gunnery Department manned 5-inch and 20mm guns, stood watches in Sky Control, guarded the brig, provided ship security in port, and served as the ship's landing force just before the end of the war.
