Edited sentence: Before 1805, the Royal Navy suffered only one other other strategic defeat—during the American Revolution at the Battle of the Chesapeake in 1781 against a French fleet commanded by the able Comte de Grasse.However, in 1741 the British navy suffered its greatest defeat in maritime history off the Spanish port of Cartagena de Indias (present-day Colombia) after Admiral Vernon led an enormous fleet of 186 ships and 23,000 men, the largest naval expedition in world history with the exception of the Battle of Normandy, with the aim of weakening Spain's control of the Caribbean and disrupting the Spanish convoys of precious metals.Instead, after a month of intense gunfire the British fleet withdrew in defeat after loosing over 50 ships and 18,000 men (See Battle of Cartagena in War of Jenkin's Ear).The Napoleonic Wars saw the Royal Navy reach a peak of efficiency, dominating the navies of most of Britain's adversaries.This prolonged Spain's domination of the Atlantic waters, and delayed Britain's naval supermacy on the world stage until the early 19th century
