The raid on Lorient was a British amphibious operation in the region around the town of Lorient from 29 September to 10 October 1746 during the War of the Austrian Succession. It was planned as an attempt to force the French to withdraw their forces from Flanders to reinforce their own coast. At the same time, as Lorient was used by the French East India Company as a base and supply depot, its destruction would serve British objectives in the East Indies.
Around 4500 British soldiers were embarked, but the ships carrying them had to wait off the Lorient coast several days, allowing the town to organise its defences and call in reinforcements from other towns in the region. The British troops only arrived in the outskirts of the town on 3 October and negotiations for the town's surrender were ended by the bombardment of 5–7 October. On 7 October the British force was ordered to retreat. The British engineers' incompetence and losses to disease and fatigue forced the commander to stop his offensive. At the same time, the French commander originally planned to surrender, believing his enemy to have an overwhelming numerical superiority and knowing the weakness of his defences and the poor training and weaponry of his own troops. He made a surrender offer on 7 October, shortly after the enemy's departure, and never received a reply.
The raid is notable for its military results, such as forcing the French to develop fortifications in southern Brittany, but also for its cultural consequences, such as starting a controversy between David Hume and Voltaire and giving rise to a cult of the Virgin Mary in the town along with several songs describing the siege.
