HMS Hannibal was a 74-gun third-rate ship of the line of the Royal Navy, launched on 15 April 1786, named after the Carthaginian general Hannibal. She is best known for having taken part in the Algeciras Campaign, and for having run aground during the First Battle of Algeciras on 5 July 1801, which resulted in her capture. She then served in the French Navy until she was broken up in 1824.

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.
