On 14 September 1807 Barbara was returning to Demerara from Devils Island when she sighted a brig making for her.

An engagement followed; after a well-contested action of half an hour the French were able to board and capture Barbara.

[b] In July 1808, the master of an American brig claimed the protection of a convoy from Jamaica, which the 64-gun HMS Veteran was escorting.

[7] The French privateer cutter Pératy, under the command of M. Maurison (or Moriseau[8]), took up position in the convoy's path, hoping to capture some of the ships.

HMS Guerriere surprised and captured the privateer on 17 July after a chase lasting 24 hours.

[7][9] A prize crew took Pératy to Halifax, Nova Scotia, where the Admiralty purchased her and took her back into service.

At daybreak on 11 February 1813, Barbara found herself some three miles from the Boulogne pier and near an anchored French lugger.

[11] The next month Barbara joined Rear-Admiral George Hope's squadron and with it sailed to the Baltic.

[12][c] A month later, on 13 April, Barbara was at Aalborg where she cut out of the anchorage a ship of 400 tons, two galliots, and a sloop, loaded with grain for the Norwegian market.

[11] Next she moved to the entrance of the Kattegat, where she spent several months skirmishing with Danish naval vessels and flying batteries on shore.

[11] The next month, on 11 August, 26 of Barbara's men in her boats landed on Great Grasholm island.

Although Barbara only suffered one man wounded, she was badly damaged and had to put into Hawk roads, Gothenburg.

[11] In the early evening of 6 October, Lieutenant Richard Banks of the gun-brig Forward received intelligence that a Danish privateer of one gun was sailing towards an anchorage about four miles from Wingo Sound near Goteborg that English merchantmen were wont to use.

(Morgan resigned his commission in July to return to Gothenburg to salvage what he could of his affairs following the bankruptcy of his prize agents there.
