On 1 April Invincible, Captain William Cayley, was escorting a convoy to the West Indies.

They encountered the French privateer Alexander, and her prize, the Portuguese vessel "Signior Montcalm", and captured them at (37°11′N 18°16′W / 37.183°N 18.267°W / 37.183; -18.267).

Alexander was armed with ten guns and had a crew of 65 men under the command of M. Petre Edite.

[9] Admiral Henry Harvey, commander-in-chief of the Leeward Islands Station, decided to use the captured vessel as a tender to his flagship HMS Prince of Wales.

[3] Alexandria and Pickerell were apparently at the capture of Trinidad (21 February 1797), the unsuccessful attack on Puerto Rico (17 April 1797).

[11] In September Alexander delivered dispatches to the Governor of Demerara and to Captain Jemmett Mainwaring of Babet, after which Senhouse sailed for Barbados.

At daylight on 4 October Alexandria was some five or six leagues west of Barbados when she sighted a schooner in pursuit of an American brig.

The most important occurred on 9 October 1799 when he captured a privateer of eight guns and 70 men after an engagement that lasted three-quarters of an hour.

On 12 September, 1800, under command of Lt. John Morrell, she made contact with USS Philadelphia between Deserada and Antigua.
