During the Seven Years' War (1756–1763) the British captured the island in 1757 and destroyed its ramparts as part of the attempted Raid on Rochefort, before withdrawing several weeks later. The island of Île-d'Aix was again captured by British forces in 1759 following the Battle of Quiberon Bay and occupied until the end of the war in 1763. The fortifications were then rebuilt by several French officers, including Pierre Choderlos de Laclos, the author of "Les Liaisons dangereuses".
