The British 44-gun frigate HMS Salsette captured Opyt in 1808 in the Baltic during the Anglo-Russian War (1807-1812) after her captain and crew put up heroic resistance.

28 May] 1808, she arrived at Sveaborg from Kronshtadt to join the division under Captain of 2nd rank Lodewijk van Heiden (who went on to become the Russian Admiral at the Battle of Navarino in 1827), to help in the city's defense.

11 June] 1808, Captain Walter Bathurst and Salsette chased a Russian sloop-of-war to Reval and captured a galliot partly laden with spirits at anchor in the roads.

As Bathurst was bringing out his prize he saw a Russian cutter off the north end of Nargen island (now Naissaar),[3] which defends Reval from the sea.

[2]The British discovered that Opyt had left Sveaborg that day to join the Russian sloop Charlotta, which Salsette had unsuccessfully chased.

[8] Then on 7 March 1809, Baltic was in company with the sloop Ranger when they captured the Danish ships Magdalena, Boletta, Britannia, Den Gode Hensight, Walhala, and Christina.

However, when the British discovered that the Russians had stretched a chain across the entrance to the harbor, precluding an attack by fireships, Saumarez abandoned the plan; the two vessels returned to normal duties.
