 ships cruising off the coast of Northern France. Seeking to eliminate the British presence on the islands and simultaneously test the equipment and tactics then being developed in France for a projected invasion of Britain, the French launched a massed amphibious assault on the southern island using over 50 landing ships and thousands of troops on 7 May 1798. Although significant Royal Navy forces were in the area, a combination of wind and tide prevented them from intervening and the island's 500-strong garrison was left to resist the attack alone.

Despite the overwhelming French majority in numbers, the attack was a disaster: nearly 1,000 French soldiers were killed as the boats were caught in open water under the island's gun batteries: several were sunk with all hands. Heavy fire from batteries and Royal Marines

Although this operation indicated the probable result of a full-scale invasion of Britain, the threat remained and British forces began a close blockade of the surviving landing craft that were anchored in the Cotentin ports. A month after the battle this strategy resulted in a secondary success when a French frigate

Since the 1796 French victory in Italy over the Austrians, pressure had been growing in France for direct action against Britain. Command of an army deployed in Northern France and named the Armée d'Angleterre was initially given to General Napoleon Bonaparte, but later passed to General Kilmaine. Bonaparte, and then Kilmaine, prepared for an invasion of Britain and Captain Muskein, a naval administrator from Antwerp, was instructed to develop a suitable fleet of landing craft

In April 1798, Muskein was ordered to prepare a squadron of his barges for an attack on the Saint Marcouf Islands. The operation was intended simultaneously to eradicate the British garrison and restore French control of the raiding base, test the effectiveness of the barges in a military amphibious operation, and focus British naval attention on the English Channel and away from Bonaparte's preparations at Toulon

, to the west of the islands. There he waited for the right combination of wind and tide to allow the attack to go ahead uninterrupted by the British squadron that had followed his flotilla westwards.

Battle

On 6 May the conditions for Muskein's attack were perfect: the calm winds prevented the British warships intercepting his flotilla, and the weak tides prevented disruption to his craft by heavy waves. The British also were aware of the conditions necessary for the attack, and made swift preparations to arm the batteries and line the shore with Royal Marines

 under Commander William Haggitt, had joined Adamant, which was stranded 6 nautical miles (11.1 km) away from the islands by the calm. Despite strenuous efforts, the three vessels would not be able to reach the islands in time to take part in the action.

At midnight, the island's boat signaled the approach of the French and Lieutenant Price readied the defences. Muskein's force mustered 52 vessels, including a number of brigs that mounted several large cannon and were intended to provide covering fire for the landing barges. The main body of the attacking troops numbered between 5,000 and 6,000 French soldiers drawn largely from coastal defence units based around Boulogne. Unwilling to risk a night attack, Muskein waited until dawn, using the remaining cover of night to draw his craft in formation facing the western defences of the southern island. The gunbrigs lay 300 yards (274.3 m) offshore, behind the landing barges whose approach they would cover during the attack. As dawn broke, Muskein ordered the advance and the gunbrigs and smaller cannon in the barges opened fire on the British defences.

The West Island's batteries, under Lieutenant Price, consisted of 17 cannon: four 4, two 6, and six 24-pounder long guns, and three 24, and two 32-pounder carronades. Although eight of the guns were relatively light, the batteries inflicted devastating damage on the light invasion craft. Despite severe casualties the French barges continued their approach until they were within musket

. Six or seven boats sank with their entire crews and troops, and others were heavily damaged. Losses were so high that the French called off the attack; even so, the return journey carried the barges past East Island, which was under the command of Lieutenant Richard Bourne of Sandfly and mounted a battery of two 68 pounder carronades, massive guns that inflicted additional severe losses. Although Hotham's squadron made desperate efforts to reach the battle, the wind was too light and they were only able to chase the remaining ships back into Saint-Vaast-la-Hougue.

Aftermath

The battle was a disaster for the French. According to unofficial accounts, they lost approximately 900 men killed or drowned and at least 300 wounded, in addition to the loss of a number of the newly-constructed landing craft. In France the newly appointed Minister of Marine Étienne Eustache Bruix

. Muskein was ordered to return to Le Havre with the remainder.

In Britain the successful defence of the islands was highly praised and Price was promoted as a reward, although Bourne was not, despite a recommendation in the official report. British losses included a single marine killed and four other personnel wounded. The victory was seen in Britain as a foreshadowing of the likely fate of an attempted invasion and helped ease British fears about the threat of a French amphibious attack. Nearly five decades later the Admiralty issued the Naval General Service Medal with clasp "Isles St. Marcou" upon application to all British participants then still living.

The British strengthened the islands' defences, in case of further attacks, and a number of warships patrolled the area to observe French movements and intercept any flotillas of invasion craft. At the Action of 30 May 1798
