At the beginning of the American Revolutionary War (1775–83), the Royal Navy dealt with the fledgling Continental Navy handily, destroying or capturing many of its vessels. However, France soon took the American side, and in 1778 a French fleet sailed for America, where it attempted to land at Rhode Island and nearly engaged with the British fleet before a storm intervened, while back home another fought the British in the First Battle of Ushant. Spain and the Dutch Republic entered the war in 1780. Action shifted to the Caribbean, where there were a number of battles with varying results. A Spanish fleet was defeated at the battle of Cape Saint Vincent in 1780 while a Franco-Spanish fleet was defeated in the West Indies in 1782. The most important operation came in 1781 when, in the Battle of the Chesapeake, the British failed to lift the French blockade of Lord Cornwallis, resulting in a British surrender in the Battle of Yorktown. Although combat was over in North America, it continued in the Caribbean (Battle of the Saintes) and India, where the British experienced both successes and failures. Though Minorca had been recaptured, it was returned to the Spanish. The relief of Gibraltar later the same year symbolised the restoration of British naval ascendancy, but this came too late to prevent the independence of the Thirteen Colonies.
