Deux Frères was a tartane that the French Navy had requisitioned in March 1798 at Marseille and commissioned as a transport.
[1] A British division under the command of Commodore Sir Sidney Smith in Tigre 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.
[2] 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.
