The Battle of the Saintes was an important naval battle in the Caribbean between the British and the French that took place 9–12 April 1782. The British victory was considered their greatest over the French during the American Revolutionary War.^[65] The British fleet under Admiral Sir George Rodney defeated a French fleet under the Comte de Grasse, forcing the French and Spanish to abandon a planned invasion of Jamaica.^[66] The French had blockaded the British Army at Chesapeake Bay the year before, during the Siege of Yorktown, and supported the eventual American victory in their revolution. This battle, however, halted their momentum and had a significant effect on peace negotiations to end the war.^[67] The French suffered heavy casualties at the Saintes and many were taken prisoner, including de Grasse. Four French ships of the line were captured (including the flagship) and one was destroyed.
