French corsair Robert Surcouf, commander of the 18-gun ship La Confiance, captures the British 38-gun Kent inspiring the traditional French song Le Trente-et-un du mois d'août.

Robert Surcouf (12 December 1773 8 July 1827) was a French privateer and slave trader who operated in the Indian Ocean between 1789 and 1801, and again from 1807 to 1808, capturing over 40 prizes. He later amassed a large fortune as a ship-owner, from privateering, commercial activities, the illegal slave trade, and as a landowner.Surcouf started his career as a sailor and officer on the Aurore, Courrier d'Afrique and Navigateur. Having risen to captain, and in spite of the prohibition of slave trading by the National Convention in 1793, he engaged in the business himself as a captain on Crole. He then captained the merchantman milie, on which he engaged in commerce raiding despite lacking a letter of marque. He preyed on British shipping, capturing the East Indiaman Triton, before returning to le de France in the Indian Ocean, where his prizes were confiscated. He then returned to France, where he obtained prize money from the government.

Returning to the Indian Ocean, Surcouf captained the privateers Clarisse and Confiance, raiding British, American, and Portuguese merchantmen. He captured the East Indiaman Kent on 7 October 1800. Returning to France, he was awarded the Legion of Honour and settled as a ship-owner.

He briefly returned to the Indian Ocean in 1807 on the custom-built Revenant before returning to France. There, he armed privateers and merchantmen. His privateers led successful campaigns against British trade in the Indian Ocean and disastrous ones in the English Channel, except for Renard. This cutter achieved fame in her very costly victory over HMS Alphea on 9 September 1812 which exploded after repulsing French attempts at boarding. There were many casualties. After the Bourbon restoration, he organised fishing expeditions to Newfoundland and amassed a considerable fortune. He died in 1827 and is buried in a graveyard at Saint-Malo.

Corsairs (French: corsaire) were privateers, authorized to conduct raids on shipping of a nation at war with France, on behalf of the French crown. Seized vessels and cargo were sold at auction, with the corsair captain entitled to a portion of the proceeds. Although not French Navy personnel, corsairs were considered legitimate combatants in France (and allied nations), provided the commanding officer of the vessel was in possession of a valid letter of marque (lettre de marque or lettre de course, the latter giving corsairs their name), and the officers and crew conducted themselves according to contemporary admiralty law. By acting on behalf of the French Crown, if captured by the enemy, they could in principle claim treatment as prisoners of war, instead of being considered pirates. Because corsairs gained a swashbuckling reputation, the word "corsair" is also used generically as a more romantic or flamboyant way of referring to privateers, or even to pirates. The Barbary pirates of North Africa as well as the Ottoman Empire were sometimes called "Turkish corsairs".
