[4] In 1810, Britomart was stationed in the North Sea primarily off the Frisian Islands of Texel and Vlie to help enforce the naval blockade of that coast.

[9] Britomart and Calliope shared in the proceeds of the capture on 2 September of the Danish vessels Goede Verwagting and Frou Esje.

[11][12] Britomart, Osprey, and Leveret were in company on 16 July 1812 when they encountered the French privateer lugger Éole some 25 miles N. W. of Heligoland.

[b][c] Also in July Britomart participated in an attack on the batteries at Spikeroog, where she sustained a loss of one man killed and another wounded.

[14] In August Britomart's boats cut out two vessels from beneath the protection of 20 gun-boats in the river Ems.

When Tulloh arrived, Britomart was ordered to the Baltic to participate in conducting 17 Russian ships of the line to England.

An Anglo–Dutch naval force under the command of Admiral Edward Pellew, 1st Viscount Exmouth bombarded ships and the harbour defences of Algiers.

In 1847 the Admiralty authorized the issue of the clasp "Algiers" to the Naval General Service Medal to the surviving claimants from the action.

[1] Disposal: The "Principal Officers and Commissioners of His Majesty's Navy" offered the "Britomart brig, of 238 tons", lying at Plymouth, for sale on 3 February 1819.

On 1 September 1821 an advertisement appeared in The Times that Britomart, Daniel Peache, commander, would be beginning a regular packet service between London and Van Diemen's Land and New South Wales, and that she had room for only a few passengers.

[28][e] A report from Mauritius dated 7 July 1827 stated that Britomart would be bringing back part of the cargo of Clydesdale, which had been condemned there.

Under Captain Blake (see below), Britomart served as a transport, visiting Corfu on one voyage and Fernando Po on another.

She left Fernando Po on 21 January 1829 with nine pirates that HMS Eden had captured, and arrived at Deal on 1 April.

There are reports that between 1834 and 1836 Captain William MacDonald sailed Britomart between Hobart and the Australian mainland, particularly Sydney.
