HMS Alexander was a 74-gun third-rate of the Royal Navy. She was launched at Deptford Dockyard on 8 October 1778. During her career she was captured by the French, and later recaptured by the British. She fought at the Nile in 1798, and was broken up in 1819. She was named after Alexander the Great.
On 13 March 1780, Alexander and HMS Courageaux captured the 40-gun French privateer Monsieur after a long chase and some exchange of fire. The Royal Navy took the privateer into service as HMS Monsieur.
In 1794, whilst returning to England in the company of HMS Canada after escorting a convoy to Spain, Alexander, under the command of Rear-Admiral Richard Rodney Bligh, fell in with a French squadron of five 74-gun ships, and three frigates, led by Joseph-Marie Nielly.[1] In the action of 6 November 1794 Alexander was overrun by the Droits de l'Homme, but escaped when she damaged the Droits de l'Hommes rigging. Alexander was then caught by Marat, which came behind her stern and raked her. Then, the 74 gun third-rate Jean Bart closed in and fired broadsides at close range, forcing Bligh to surrender Alexander. In the meantime, Canada escaped.[1] The subsequent court martial honourably acquitted Bligh of any blame for the loss of his ship.[1]
The French took her to Brest and then into their French Navy under the name Alexandre.[1] On 22 June 1795, she was with a French fleet off Belle Île when the Channel Fleet under Lord Bridport discovered them. The British ships chased the French fleet, and brought them to action in the Battle of Groix. During the battle HMS Sans Pareil and HMS Colossus recaptured Alexander.[1] After the battle, towed her back to Plymouth.
