The Glorious First of June (also known as the Third Battle of Ushant, and in France as the Bataille du 13 prairial an 2 or Combat de Prairial) of 1794 was the first and largest fleet action of the naval conflict between the Kingdom of Great Britain and the First French Republic during the French Revolutionary Wars. The British Channel Fleet under Admiral Lord Howe attempted to prevent the passage of a vital French grain convoy from the United States, which was protected by the French Atlantic Fleet, commanded by Vice-Admiral Louis Thomas Villaret de Joyeuse. The two forces clashed in the Atlantic Ocean, some 400 nautical miles (741 km) west of the French island of Ushant on 1 June 1794.
