On February 25th, 1760, the French privateer, François Thurot, sailed from Carrickfergus. He had occupied the town with a force of several hundred men for almost a week by that stage. Three days later, his fleet was attacked by British men-of-war near the Isle of Man and Thurot was killed in what subsequently became known as The Battle of Bishops Court or The Defeat of Thurot.

François Thurot (1726-1760) who has been described as "one of the boldest and most accomplished privateers"(1), was commissioned into the French navy during the Seven Years' War (1756-1763). Some have said that the War was the original 'world war', as Franco-British fighting in North America and India led to a general war in Europe, involving most major European states.
During the War, Thurot commanded a frigate. Together with his men, he captured a large number of British merchant ships. You can read about Thurot in this book on French buccaneers, Les Frères de la Coste: Flibustiers & Corsaires (pages 239-299). It is available to read and download on Gallica, the French National Library's digital library.
