The Battle of the Saintes (known to the French as the Bataille de la Dominique), also known as the Battle of Dominica, 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.
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.

The battle is named after the Îles des Saintes, a group of small islands between Guadeloupe and Dominica in the West Indies. 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.

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. Rodney was credited with pioneering the tactic of "breaking the line" in the battle, though this is disputed.

Background
In October 1781 Admiral Comte de Grasse, commander of the French fleet in the West Indies; Francisco Saavedra de Sangronis, General Bureau for the Spanish Indies; and Bernardo de Gálvez, court representative and aide to the Spanish Governor of Louisiana, developed a plan against British forces. The strategic objectives of the Franco-Spanish military forces in the West Indies in this plan were: to aid the Americans and defeat the British naval squadron at New York to capture the British Windward Islands and to conquer Jamaica.
This plan became known as the "De Grasse–Saavedra Convention." The first objective had been essentially met by the surrender of the British army under General Cornwallis at the Siege of Yorktown in September 1781. De Grasse and his fleet had played a decisive part in that victory, after which they returned to the Caribbean. On arrival in Saint-Domingue in November 1781, the admiral was notified to proceed with a plan for the conquest of Jamaica.
Jamaica was the largest and most profitable British island in the Caribbean, mainly because of sugar: it was more valuable to the British economy than all of the 13 American colonies. King George III wrote to Lord Sandwich, saying that he would protect Britain's important Caribbean islands at the risk of Britain herself, and this was the strategy implemented in 1779. Sugar made up 20% of all British imports and was worth five times as much as tobacco. The French and Spanish were fighting to take over Jamaica in order to expel the British from the West Indies, and to strike a massive blow against the British economy. The courts at Paris and Madrid perceived the invasion of Jamaica as an alternative to the Spanish and French attempts to take Gibraltar, which for two years had been a costly disaster.
Whilst de Grasse waited for reinforcements to undertake the Jamaica campaign, he captured St. Kitts in February 1782. The rest of the Windward Islands—Antigua, St. Lucia, and Barbados—still remained under British control. Admiral George Rodney arrived in the Caribbean theatre the following month, bringing reinforcements. These included 17 ships of the line and gave the British a slight numerical advantage.
On 7 April 1782, de Grasse set out from Martinique with 35 ships of the line, including two 50-gun ships and a large convoy of more than 100 cargo ships, to meet with a Spanish fleet of 12 ships of the line. In addition de Grasse was to rendezvous with 15,000 troops at Saint Domingue, who were earmarked for the conquest and intended to land on Jamaica's north coast. Rodney, on learning of this, sailed from St. Lucia in pursuit with 36 ships of the line the following day.
The British ships' hulls by this time had been given copper sheathing to protect them from marine growth, fouling, and saltwater corrosion, dramatically improving speed and overall sailing performance in good wind.
Opposing fleets and officers
The British flagship was HMS Formidable under Admiral Rodney. Second in command was Admiral Samuel Hood. and third was Vice Admiral Francis Samuel Drake. As was the convention of the day, the fleet was split into three sections: Rodney had individual control as Admiral of the White of 12 ships flying the White Ensign; Drake had command of 12 ships as Admiral of the Blue flying the Blue Ensign; and Hood was Admiral of the Red with 12 ships flying the Red Ensign.
