HMS Surprise (1796)

Construction

Pierre-Alexandre Forfait designed Unité, the name ship for a class of corvette. Although the French initially rated Unité as a corvette, the ships of her class bridged a gap between smaller warships and frigates, and at various times were rated as frigates.

HMS Surprise (1796)

French service

On 20 March 1794, lieutenant de vaisseau Jean le Drézénec, who was 41 years old and had entered the naval service soon after the revolution from a career in the merchant service, arrived to take command of Unité. He supervised the fitting out of the ship, and found the long guns were too large to be easily reloaded, and the lower sails were also too large. He notified the authorities, who urged him to finish fitting out the ship because a major naval operation was imminent. Soon afterwards, Unité took part in the battle of the Glorious First of June by escorting the dismasted Révolutionnaire as she was towed by the Audacieux.

HMS Surprise (1796)

In June 1794 Unité completed repairs in Saint-Malo and Brest to damage she had sustained in the battle. In the following months she escorted merchant vessels along the coasts of France. On 28 September, with the corvette Bergere and under the command of Lieutenant de Vaisseau Gouley, the two ships left Brest to sail northwest in between Ireland and the islands of the Hebrides and St Kilda to intercept enemy merchant ships. On 17 October, the ships captured a 200-ton merchant ship Dianne. The next day the weather turned foul and the two ships were separated. Unwilling or unable to continue the mission alone, Unité searched for Bergere fruitlessly for sixteen days before finally returning to Brest on 1 November.

Capture by the Royal Navy

After repairs, Unité was ordered to join the Mediterranean fleet at Toulon, and arrived there in March 1795. She spent the remainder of the year either blockaded in port or serving as a courier. In April 1796, she was ordered on one such courier mission to North Africa to deliver personnel and messages to the port of Bône. At the time, Le Drézénec, who had been recently promoted to capitaine de frégate, was suffering from smallpox and was incapacitated. Consequently, her first lieutenant, Lieutenant Le Breton, commanded Unité.

Captain Thomas Fremantle in command of the frigate HMS Inconstant had heard there was a French frigate in Bône, and sailed to intercept her. When Unité arrived in the afternoon of 20 April 1796, the watch aboard Unité identified Inconstant as a neutral vessel and Le Breton did not clear the ship for action. About an hour later, Inconstant sailed alongside, boarded and captured Unité intact.

Royal Navy

Commander Edward Hamilton, commissioned Surprise in June 1796. He sailed for Jamaica on 29 July. He was promoted to post captain in July 1797. She returned to England and underwent refitting at Plymouth between January and May 1798.

She returned to the Caribbean and sailed on the Jamaica station.

In November, Surprise and Amaranthe captured the French 4-gun privateer Petite Française. On 19 March 1799 Surprise captured Betsey and the 5-gun Lionne.

Then on 17 April Surprise captured Chien de Chasse.

On 10 October 1799 in the harbour of Aruba she used her boats to cut out a privateer of ten guns and two sloops. One of her officers, an acting lieutenant, was killed in the action. She then sailed on to Venezuela.

Recapture of HMS Hermione

Surprise gained fame for the cutting-out expedition on 25 October 1799 of . Hermiones crew had mutinied, and had sailed her into the Spanish possession of Puerto Cabello. Captain Edward Hamilton of Surprise led a boarding party to retake Hermione and, after an exceptionally bloody action, sailed her out under Spanish gunfire. The Spanish casualties included 119 dead; 231 were taken prisoner, while another 15 jumped or fell overboard. Hamilton had 11 injured, four seriously, but none killed.

In January 1801 Captain Christopher Laroche assumed command of Surprise. Captain James Oswald replaced Laroche in August.

Fate

After the Treaty of Amiens, the Royal Navy sold Surprise out of the service at Deptford in February 1802 and she was broken up.
