American War of Independence

1775–1783

What began as a colonial rebellion became a world war at sea. The Continental Navy and the state navies could only raid, but France joined the Americans in 1778, Spain in 1779 and the Dutch Republic was dragged in in 1780, and for the first time in a century Britain faced the fleets of Europe without an ally. The war was fought from Lake Champlain to the Bay of Bengal. De Grasse's victory off the Chesapeake trapped Cornwallis at Yorktown and decided American independence; Rodney's victory at the Saintes the next spring saved Jamaica and let Britain make peace on better terms. Off India, Hughes and Suffren fought five hard battles in eighteen months without either losing a ship in action.
