Wikipedia Overview

The action of 6 April 1809 was a small naval battle fought between the French frigate Niémen and several British frigates, principally HMS Amethyst, as part of the blockade of Brest, France, during the Napoleonic Wars. During the Wars, a central part of British strategy was to isolate French ports from international trade in an attempt to both restrict French imports of food and military supplies and simultaneously to damage the French economy. To achieve this, British warships maintained a constant vigil off the French coastline, attacking ships that attempted to enter or leave French ports. Despite the threat that their ships faced, communication and the transfer of supplies between France and her colonies was vital to the French war effort, and the French Navy made constant attempts to evade the patrolling British squadrons. In late 1808, a significant French squadron was deployed to Isle de France to disrupt British trade in the Indian Ocean. This force required reinforcement and supply from France, and periodic attempts were made to reach the isolated convoy with new frigates, the first of which was Niémen.
