In 1801 Vice Admiral Horatio Nelson chose Elephant as his flagship during the Battle of Copenhagen due to its suitability for the shallow waters there. It was on this ship that he is said to have put his telescope to his blind eye and claimed not to be able to see a signal ordering him to withdraw. She lost 9 killed and 13 wounded then.[1]

The ship participated in the blockade of Saint-Domingue in the same year. The British patrolled off Cap-François. On 24 July the squadron, made up of Bellerophon, Elephant,, and HMS Vanguard, came across two French 74-gun ships, Duquesne and Duguay-Trouin, and the frigate Guerrière, attempting to escape from Cap-François.[2] The squadron gave chase, and on 25 July overhauled and captured Duquesne after a few shots were fired, while Duguay-Trouin and Guerrière managed to evade their pursuers and escape to France.[3] One man was killed aboard Bellerophon during the pursuit.[2] Elephant remained blockading Cap-François until November, when the French commander of the garrison there, General Rochambeau, was forced to surrender.
To prevent Rochambeau escaping, launches from Bellerophon and Elephant went into the Caracol Passage where they cut out the French schooner on 22–23 November. The French formally surrendered on 30 November.
HMS Elephant, under the command of Francis Austen, captured the United States privateer Swordfish in December 1812 during the War of 1812.
