The Battle of the Îles Saint-Marcouf was fought off the Îles Saint-Marcouf on 7 May 1798 during the French Revolutionary Wars. Dislodging a British garrison on the islands was the main objective for French forces. The garrison (which had been in place since 1795) allowed the islands to serve as a resupply base for Royal Navy ships patrolling northern French waters. Apart from expelling the British, the French sought to test new equipment and tactics, which had allegedly been developed with an intention of invading Britain. On 7 May, French forces launched a massed amphibious assault on the southern island, using over 50 landing ships and hundreds of troops. The island's 500-strong garrison was compelled to resist the attack alone; although significant Royal Navy forces were in the area, a combination of wind and tides prevented them from intervening. Despite the superior numbers of the French attackers, the operation was a complete failure. The landing ships were exposed to heavy British fire, from both shore batteries and musket fire.
