John Cooke was an experienced and highly regarded officer of the Royal Navy during the American War of Independence, the French Revolutionary Wars and the first years of the Napoleonic Wars. Cooke is best known for his death in hand-to-hand combat with French forces during the Battle of Trafalgar in 1805. During the action, his ship HMS Bellerophon was badly damaged and boarded by sailors and marines from the French ship of the line Aigle. Cooke was killed in the ensuing melee, but his crew successfully drove off their opponents and ultimately forced the surrender of Aigle.

HMS Bellerophon, known to sailors as the "Billy Ruffian", was a ship of the line of the Royal Navy. A third-rate of 74 guns, she was launched in 1786. Bellerophon served during the French Revolutionary and Napoleonic Wars, mostly on blockades or convoy escort duties. She fought in three fleet actions: the Glorious First of June (1794), the Battle of the Nile (1798) and the Battle of Trafalgar (1805). While the ship was on blockade duty in 1815, Napoleon boarded Bellerophon so he could surrender to the ship's captain, ending 22 years of almost continuous war between Britain and France.
