In 1815, a United States privateer captured her, but the Royal Navy recaptured her.

Hercules was on her way from Bristol to Jamaica, and Josephine was on her way from Liverpool to St Lucia.

[3] On 24 February 1815, the United States letter of marque Hollins, of 10 guns and 70 men, captured Hercules at 13°6′N 57°46′W / 13.100°N 57.767°W / 13.100; -57.767, some 112 mi (180 km) east of Barbados.

[4][a] The schooner HMS Canso recaptured Hercules off Abacco on 9 March, and reportedly sent her to Halifax.

Therefore, any vessel that the Americans had captured before March 1, i.e., during wartime, such as Hercules, was a valid prize, and a vessel recaptured after 1 March, such as Hercules, was recaptured during peacetime, and so not a valid prize.
