Charles-Alexandre Léon Durand, Comte de Linois was a French admiral who served in the French Navy during the reign of Napoleon Bonaparte. He commanded the combined Franco-Spanish fleet during the Algeciras Campaign in 1801, winning the First Battle of Algeciras before losing the Second Battle of Algeciras. He then led an unsuccessful campaign against British trade in the Indian Ocean and South China Sea in 1803, being defeated by a harmless fleet of the East India Company during the Battle of Pulo Aura and ending his cruise and sea-going career being bested in battle by John Warren in the action of 13 March 1806. Following the Bourbon restoration, Linois was appointed Governor of Guadeloupe. He supported Napoleon during the Hundred Days and so, on his return to France, he was forced to resign and was court martialled. Although acquitted, he was placed in retirement and never served again.

The Algeciras campaign was an attempt by a French naval squadron from Toulon under Contre-Admiral Charles Linois to join a French and Spanish fleet at Cadiz during June and July 1801 during the French Revolutionary Wars prior to a planned operation against either Egypt or Portugal. To reach Cadiz, the French squadron had to pass the British naval base at Gibraltar, which housed the squadron tasked with blockading Cadiz. The British squadron was commanded by Rear-Admiral Sir James Saumarez. After a successful voyage between Toulon and Gibraltar, in which a number of British vessels were captured, the squadron anchored at Algeciras, a fortified port city within sight of Gibraltar across Gibraltar Bay. On 6 July 1801, Saumarez attacked the anchored squadron, in the First Battle of Algeciras. Although severe damage was inflicted on all three French ships of the line, none could be successfully captured and the British were forced to withdraw without HMS Hannibal, which had grounded and was subsequently seized by the French.
