The Russian coastal fleet consisted of nine archipelago frigates, 13 "xebec"s, two mortar ships, four gun prams, three floating batteries, 26 galleys, six schooners, four cutters, 77 gun sloops and 121 lightly armed boats. The Russian fleet carried around 900 cannons compared to 450 Swedish cannons and had clear superiority in both number of ships and men. The Russian coastal fleet was eager to attack, especially on 9 July, the anniversary of Catherine the Great's proclamation as Empress of Russia. Recognizing the failure to decisively defeat the Swedish archipelago fleet a year earlier at the same location, the Russian commander, Prince Charles of Nassau-Siegen, chose to commit his whole force from the south. This was done to prevent the Swedes from escaping to the shelter of Svartholm fortress since Nassau-Siegen was expecting a clear victory, having numerical superiority in ships, artillery as well as in men.
