The Siege of Saint-Martin-de-Ré, also Siege of St. Martin's (French:Siège de Saint-Martin-de-Ré), was an attempt by British forces under the Duke of Buckingham to capture the French fortress-city of Saint-Martin-de-Ré, on the isle of (near La Rochelle), in 1627. After three months of siege the Marquis de Toiras and a relief force of French ships and troops managed to repel the Duke, who was forced to withdraw in defeat.[5] This encounter followed another defeat for Buckingham, the 1625 Cádiz Expedition, and is considered to be the opening conflict of the Anglo-French War of 1627-1629, itself a part of the Thirty Years' War.


On 12 July 1627, an English force of 100 ships and 6,000 soldiers[6] under the command of the Duke of Buckingham invaded the Île de Ré, landing at the beach of Sablanceau, with the objective of controlling the approaches to La Rochelle and encouraging rebellion in the city. Buckingham hoped to capture the Fort of La Prée and the fortified city of Saint-Martin-de-Ré.[7] A Royal French force of 1,200 infantry and 200 horsemen under the Marquis de Toiras, the island's Governor, resisted the landing from behind the dunes, but the English beachhead was maintained, with over 12 officers and 100 men killed.[8]

During a period of three days in which Buckingham consolidated his beachhead, Toiras took all available provisions on the island and fortified himself in the citadel of Saint Martin.[9] Buckingham endeavoured to establish a siege around the citadel, but this proved difficult; the English siege engineer had drowned during the landing, the cannon were too few and too small, and, as Autumn arrived, disease started to take its toll on the English troops. The siege continued until October.[10]


Requested supplies from England proved insufficient. Two thousand Irish troops arrived under Sir Ralph Bingley on 3 September 1627. A small supply fleet under Sir William Beecher arrived with only 400 raw troops.[11]

A Scottish fleet composed of 30 ships, with 5,000 men, was on its way on October 1627, but was broken up by a storm on the coast of Norfolk.[12]

A strong relief fleet under the Earl of Holland only departed on 6 November 1627, which proved to be too late.[13]

The French, despite difficulties, managed to get a supply fleet through to the defenders on the night of 7–8 October, with 29 out of 35 ships eluding the English naval blockade. From the mainland, 4,000 additional troops were landed on the southern end of the island on October 20.[14] The rescue troops were under the Marshal of France Henri de Schomberg.[15]

Final assault and retreat

On October 27 Buckingham attempted a last desperate attack on Saint Martin,[16] but the English ladders turned out to be too short to scale the walls, and the fortress again proved impregnable.[17]

Although there were indications that the Saint Martin French garrison was also close to exhaustion, Buckingham finally retreated with his troops towards the northern part of the island, with the objective of embarking from the area of Loix. He was harassed by pursuing French troops, with heavy casualties.[18] Altogether, Buckingham lost more than 5,000 men in the campaign, out of a force of 7,000.[19]


Two months into the siege, the people of La Rochelle finally started open hostilities against the central government of France in September, initiating the Siege of La Rochelle.

Following the defeat of Buckingham in October, England attempted to send two fleets to relieve La Rochelle. The first one, led by William Feilding, Earl of Denbigh, left on April 1628, but returned without a fight to Portsmouth, as Denbigh "said that he had no commission to hazard the king's ship in a fight and returned shamefully to Portsmouth".[20]

Back in England, Buckingham tried to organise a second campaign to relieve the Siege of La Rochelle, but he was stabbed and killed at Portsmouth on August 23, 1628 by John Felton, an army officer who had been wounded in the earlier military adventure and believed he had been passed over for promotion by Buckingham. Felton was hanged in November and Buckingham was buried in Westminster Abbey. The second fleet was finally dispatched under the Admiral of the Fleet, the Earl of Lindsey in August 1628, but remained blocked by the seawall in front of La Rochelle.[21]

Exhausted and without hope of outside support anymore, La Rochelle finally surrendered to French Royal forces on 28 October 1628. Following these defeats, England would end its involvement with the Thirty Years War, by negotiating peace treaties, with France in 1629 and Spain in 1630, to the dismay of Protestant forces on the continent.[22]

Following these conflicts, the main port of Saint Martin, was further fortified by Vauban in 1681.
