On 30 March 1811, Algerine, under the command of Lieutenant Thomas Greenwood, seized the smuggling vessel Mandamus.

On 13 July 1811, Algerine, again under Blow, and the 12-gun brig-sloop Brev Drageren, under Thomas Barker Devon, engaged three Danish brigs in Long Sound, Norway, the 20-gun Lolland, the 18-gun Lougen, and the 16-gun Kiel.

[4] In the second day’s fight, Algerine sent a boat with ten men and sweeps to Brev Drageren, which helped her escape the Danes, though not until after her crew had rowed for 30 hours.

[3][4] On 15 July the gun-brig Wrangler, under Lieutenant J.B. Pettit (or Pettet), captured the Danish sloop Experiment, P. Loft, Master.

[7] In October, a court martial dismissed Blow from Algerine after he challenged a Captain Campbell of the Marines to a duel.

Admiral Sir James Saumarez had transmitted to Blow the acknowledgments of the Board of Admiralty for his skillful manoeuvres, which detached the remainder of the enemy's force, and for his exertions in facilitating the subsequent escape of himself and consort.
