On 13 May 1815 "Alcmene", with Captain Jeremiah Coghlan in command, was present at the surrender of Naples during the Neapolitan War. A British squadron, consisting of "Alcmene", and more importantly the 74-gun , the sloop , and the brig-sloop blockaded the port and destroyed all the gunboats there. Parliament voted a grant of £150,000 to the officers and men of the squadron for the property captured at the time, with the money being paid in May 1819.
