During the Napoleonic Wars, the Anglo-Russian War (2 September 1807– 18 July 1812) was the phase of hostilities between the United Kingdom and Russia after the latter signed the Treaty of Tilsit that ended its war with France. Anglo-Russian hostilities were limited primarily to minor naval actions in the Baltic and Barents Seas.

After Napoleon I defeated the Russians at the Battle of Friedland (14 June 1807), Tsar Alexander I of Russia signed a peace treaty, known as the Treaty of Tilsit. Although the treaty was quite unpopular within the Russian court, Russia had no alternative as Napoleon could easily cross the Neman River (then the Russian border) and invade Russia.

The terms of the treaty obliged Russia to cease her maritime trade with Great Britain. This closure was a part of Napoleon's continuing efforts to establish the Continental System, strengthening economic ties between the different countries in Europe under French domination. Napoleon's objective was to close one of Britain's most important markets and thus force it economically into submission.

On 26 October 1807, Tsar Alexander formally declared war on the United Kingdom after the British attack on Copenhagen in September 1807. He did not actively prosecute the war; Alexander instead restricted Russia's contribution to the bare requirement to close off trade. The British, understanding his position, limited their military response to the declaration. However, there were a few notable incidents.

The official news did not arrive in Britain until 2 December, at which time the British declared an embargo on all Russian vessels in British ports. Some 70 vessels shared in the seizure of the 44-gun Russian frigate Speshnoy (Speshnyy), then in Portsmouth harbour. The British seized the Russian storeship Wilhelmina (Vilgemina) at the same time.
