Britain sought to compel France to divert troops from Flanders back to defend its own coastline during the War of the Austrian Succession. Lorient was also strategically important as the main base and supply depot of the French East India Company, making its destruction doubly advantageous to British imperial interests.
Around 4,500 British soldiers were embarked for an amphibious assault on Lorient, but delays off the coast allowed the French to organize defenses and call in reinforcements. British troops reached the town's outskirts only on 3 October; a bombardment from 5–7 October failed to force surrender, and on 7 October the British commander ordered a retreat due to engineer incompetence and losses to disease and fatigue.
The raid compelled France to develop new fortifications along the southern Brittany coast. It also gave rise to a local cult of the Virgin Mary in Lorient, inspired several songs commemorating the siege, and ignited a literary controversy between David Hume and Voltaire. The French commander's undelivered surrender offer, sent just after the British departure, remained a historical curiosity.
