Deux Frères (1798 ship)

Deux Frères was a tartane that the French Navy had requisitioned in March 1798 at Marseille and commissioned as a transport. A British division under the command of Commodore Sir Sidney Smith in HMS Tigre (1795) captured her on 18 March 1799 at the siege of Acre in 1799. She was one of a flotilla of seven vessels and Smith took all into the Royal Navy.

At the time of her capture Deux Frères was armed with four guns and had a crew of 23 men. One of the seven captured vessels was lost in a gale at the siege; the lost vessel was almost certainly Deux Frères, as the other six have a readily identifiable subsequent history.
