Alain Emmanuel de Coëtlogon

Alain Emmanuel de Coëtlogon (4 December 1646 at Rennes – 6 June 1730 in Paris), was a Marshal of France during the reign of Louis XIV and Louis XV.

He was the seventh son of Louis de Coëtlogon, vicomte de Méjusseaume (d.1657), counsellor to the King in the Parlement of Brittany, and Louise Le Meneust de Bréquigny. He enjoyed an excellent education in Rennes, and joined a military academy, where he graduated in 1668.

He served the major part of his career under the comte de Tourville. In June 1672 he fought in the Battle of Solebay on Tourville's ship under vice-admiral d'Estrées. He also distinguished himself in the battles of Schooneveld in June 1673, and Texel in August.

On 26 January 1675, at just 29 years old, he was made captain of his own ship. He fought with Tourville around Sicily and was wounded in the Battle of Agosta where De Ruyter was mortally wounded.

In 1680, Coëtlogon studied theology and considered entering the church. Although he returned to the sea, he was profoundly changed by this spiritual experience, and led an austere, celibate life. In 1683, he commanded various ships, first around Denmark, then in North Africa. In 1688 he took part in the bombardment of Algiers under Jean II d'Estrées.

During the Nine Years' War, he was part of Château-Renault's fleet which landed French troops in Ireland, and fought in the Battle of Bantry Bay on 11 May 1689; on 1 November he was promoted to squadron leader. During the Battle of Beachy Head in July 1690, he commanded a division of the van under Tourville, destroying several Dutch ships. He also participated in the Battle of La Hogue (1692), and the Battle of Lagos (1693) where, with eight ships, he hunted down and captured five Dutch ships under the guns of the Gibraltar forts. In November 1693, he participated in the defence of Saint-Malo against the English. On 1 February 1694, he was made a knight in the Order of Saint Louis.

In May 1701, Coëtlogon was promoted to lieutenant general, and given the title of marquis, which he would never use. The following year, during the War of the Spanish Succession, he was sent to the Americas with five ships in service of Spain to protect the Spanish colonies, remaining at length in Veracruz. However, Coëtlogon was most famous for winning the Battle of Cap de la Roque off Lisbon on 22 May 1703. On board the Vainqueur, Coëtlogon, with four other ships Le Monarque, L'Éole, L'Orgueilleux and La Couronne, he defeated five Dutch ships: Muydenberg, Roosendaël, Rotterdam, Rescherner, and Gasterlandt. But the victory was not complete, and the Dutch convoy escaped.

His last battle was the Battle of Vélez-Málaga on 24 August 1704. He then became Naval Commander in Brest and received many decorations. The last four years of his life he lived in a Jesuit order. On 1 June 1730 he was finally made Marshal of France, six days before his death.

Several ships were named after Coëtlogon, especially a frigate which was active during the Boshin war (1868–1869) in Japan, and later an armoured cruiser.
