On 31 August 1806, Austerlitz was off Martinique when she encountered the 10 or 12-gun schooner HMS Prevost, which was under the command of Lieutenant Samuel Stout.

The subsequent action lasted an hour before Stout struck after having lost three men killed and seven wounded.

Admiral Sir Alexander Cochrane had been in readiness since 2 September and immediately set sail in Belleisle, together with a squadron including Prince George, Northumberland, Canada, Ramillies, Cerberus, Ethalion, and a number of other vessels including Pultusk.

The expedition also included troops from the 70th and 90th Regiments of Foot under the overall army commander, General Henry Boyer.

[8][9] In August 1808 Napier became captain of the brig-sloop Recruit;[8] his replacement on Pultusk was Commander George Pringle.

Once she was ready for sea, Pultusk went to St John's roads, where she took on board a number of French prisoners for Barbados.

Pultusk helped enforce the British blockade of Guadeloupe and took several vessels attempting to enter Basse-Terre.

[1] Four decades later the operation was among the actions recognised by the clasp "Martinique" attached to the Naval General Service Medal (NGSM), awarded upon application to all British participants still living in 1847.

One of these vessels Putusk captured while enforcing the blockade was the brig Admiral Decres, which she ran on shore under some batteries.

[1] A British squadron under Captain George Miller in Thetis arrived at Deshaies on 12 December to reconnoiter the harbour.

On 18 December Pultusk brought to Admiral Alexander Cochrane, in Pompee at Marie-Galante the news that two of the French frigates that had captured and burned Junon were anchored three leagues NW of the town of Basse-Terre.

Scorpion succeeded in her mission and the Royal Navy took Oreste into service as HMS Wellington.
