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 First Battle of Algeciras was a naval battle fought on 6 July 1801 between a squadron of British Royal Navy ships of the line and a smaller French Navy squadron at anchor in the fortified Spanish port of Algeciras in the Strait of Gibraltar. The British outnumbered their opponents, but the French position was protected by Spanish gun batteries and the complicated shoals that obscured the entrance to Algeciras Bay. The French squadron, under Contre-Amiral Charles Linois, had stopped at Algeciras en route to the major Spanish naval base at Cadiz, where they were to form a combined French and Spanish fleet for operations against Britain and its allies in the French Revolutionary Wars. The British, under Rear-Admiral Sir James Saumarez, sought to eliminate the French squadron before it could reach Cadiz and form a force powerful enough to overwhelm Saumarez and launch attacks against British forces in the Mediterranean Sea.
