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