Input: Question: Who was the commander of the Royal Navy during the War? Passage:During the French Revolutionary Wars the Royal Navy had exerted dominance at sea over its continental rivals, most immediately the French Navy with its principal fleet based at Brest on the Breton coast of the Bay of Biscay. To contain this fleet the British practiced a close blockade strategy; maintaining a fleet off Brest whenever weather conditions permitted to prevent the French fleet from breaking out into the Atlantic Ocean. This blockade force also limited French trade and maritime communications, attacking merchant ships and individual warships seeking to resupply or reinforce the main French fleet. This made French maritime journeys extremely hazardous even in inshore waters: in June 1795 the main French fleet had suffered a defeat at the hands of the blockade force at the Battle of Groix in the approaches to the port of Lorient, while at the Action of 13 January 1797 the independently sailing 74-gun ship of the line Droits de l'Homme was driven ashore and destroyed in the approaches to Brest by two frigates of the blockade squadron.
