HMS Mars (1794)

HMS Mars was a 74-gun third-rate ship of the line of the Royal Navy, launched in 1794. She was built at Deptford Dockyard, and was designed by Sir John Henslow.

Mars is most famous for her action on 21 April 1798 against the French ship Hercule off Brittany. After a fierce and prolonged engagement, Hercule surrendered, having suffered heavy casualties. Mars also suffered considerable damage and losses. Captain Alexander Hood of Mars was killed in the action.

Mars participated in the Battle of Trafalgar in 1805, where she played a significant role in the British victory. She engaged several enemy ships during the battle and suffered damage and casualties.

In 1806, Mars was involved in the blockade of Brest.

She continued in active service for several years, including operations in the Baltic Sea.

Mars was eventually broken up in 1823. She is remembered as a well-built and successful warship that participated in some of the most important naval battles of the Napoleonic Wars.
