Vice-Admiral Sir Thomas Masterman Hardy, 1st Baronet, GCB was a British Royal Navy officer. He took part in the Battle of Cape St. Vincent in February 1797, the Battle of the Nile in August 1798 and the Battle of Copenhagen in April 1801 during the French Revolutionary Wars. He served as flag captain to Admiral Lord Nelson, and commanded HMS Victory at the Battle of Trafalgar in October 1805 during the Napoleonic Wars. Nelson was shot as he paced the decks with Hardy, and as he lay dying, Nelson's famous remark of "Kiss me, Hardy" was directed at him. Hardy went on to become First Naval Lord in November 1830 and in that capacity refused to become a Member of Parliament and encouraged the introduction of steam warships.

The Battle of the Nile was a major naval battle fought between the British Royal Navy and the Navy of the French Republic at Aboukir Bay on the Mediterranean coast off the Nile Delta of Egypt from the 1st to the 3rd of August 1798. The battle was the climax of a naval campaign that had raged across the Mediterranean during the previous three months, as a large French convoy sailed from Toulon to Alexandria carrying an expeditionary force under General Napoleon Bonaparte. The British fleet was led in the battle by Rear-Admiral Sir Horatio Nelson; they decisively defeated the French under Vice-Admiral François-Paul Brueys d'Aigalliers.
