On 6 August Tobago was in company with,, and the schooner when they captured Hercules.
Before dawn on 18 October 1806 Tobago left Dominica where she had been replenishing her water supplies. Soon after, Salmon sighted a brig, joined by a schooner and a sloop, that all made towards Tobago. Tobago prepared for action, while attempting to steer away from the probably hostile squadron. The enemy closed by 8:30, with the schooner and sloop exchanging fire with Tobago. The French attempted to board, but Tobago repulsed the attempt. She was not able to escape though, and the French schooner was able to get her jib-boom over Tobagos taffrail and rake her with small arms fire. Salmon received a shot in the head and his men took him below decks. Sub-Lieutenant Nichols Gould assumed command and continued the fight for another half-hour but then, with Tobago having lost one man killed and 15 wounded (including Salmon), was forced to strike. Her captor was the French privateer General Ernouf, of 16 guns. Général Ernouf (1805 - 1808), was a Danish 16-gun brig, originally under the command of the notable French privateer captain Alexis Grassin. sold for 15,300 francs at Guadeloupe.
On 24 June 1807 Salmon received promotion to the rank of Lieutenant after his release and repatriation.

Vengeur herself did not surrender until Beagle came alongside, though her captain, M. Bourgnie, was wounded. Vengeur had made no captures.[1] Vengeur was the former Tobago.
The Royal Navy took Vengeur into service as HMS Vengeur, but sold her within the year.
