The Royal Navy captured her in 1796 off Île d'Yeu and brought her into British service as HMS Unite.

On 13 April 1796 Indefatigable, under the command of Captain Sir Edward Pellew was in pursuit of a French frigate.

Pellew signaled to his squadron mate HMS Révolutionnaire to sail to cut the frigate off from the shore.

[5] Pellew ordered the prize to be commanded to England by Edward Ellicott, first lieutenant of the Revolutionnaire, who was cited by his captain Francis Cole "for his very particular attention in keeping sight of the chase, and for his steady and manly conduct when close engaged.

She was three days out of Nantes, on her way to Guadaloupe with secret dispatches that she managed to throw overboard before the British took possession of her.

[7][a] On 4 March 1799 Unite and the sloop Gaiete left Portsmouth as escorts to a convoy for the West Indies.
