The Raid of Nassau (March 3–4, 1776) was a naval operation and amphibious assault by Colonial forces against the British port of Nassau, Bahamas, during the American Revolutionary War (also known as the American War of Independence). The battle is considered one of the first engagements of the newly established Continental Navy and the Continental Marines, the respective progenitors of the United States Navy and Marine Corps. The action was also the marines' first amphibious landing. It is sometimes known as the "Battle of Nassau".
