Battle of Svensksund

Circumstances in the 1780s, including the war between the Russian Empire and the Ottoman Empire, and the moving of a portion of the Russian Baltic Fleet to the Black Sea, prompted the Swedish king, Gustav III, to attack Russia in 1788. The war was also initiated to distract domestic attention from political problems and for Gustav III to be able to fulfill his role as a successful and powerful monarch. The plan was to attack Kronstadt and land a force to assault the capital, St Petersburg. ==Prelude==

Styrbjörn in the Maritime Museum in Stockholm. Styrbjörn'' was one of two ships of the type that participated in the battle. In 1790 an attempt to assault Vyborg failed, and the Swedish Navy along with King Gustav himself, was caught in the Bay of Viborg. It managed to escape through the "Viborg gauntlet" on 3 July, though with heavy losses to the deep-sea navy. After retreating to Svensksund, King Gustav made a decision to make a stand there. The Swedish coastal fleet was reinforced by 40 ships under Lieutenant-Colonel Carl Olof Cronstedt after the escape from Vyborg. Gustav made the decision to lead the fight personally and divided his forces into four brigades under lieutenant-colonels Carl Olof Cronstedt, Claes Hjelmstjerna, Victor von Stedingk, and Jakob Törning. Von Stedingk was to lead the center consisting of two hemmema (Styrbjörn and Starkotter) and two udema (Torborg and Ingeborg) archipelago frigates, brig Alexander, 15 galleys, two half-galleys, and 11 cannon or mortar longboats. Törning had the command of the right wing consisting of 39 gun sloops and 22 gun yawls while Hjelmstierna's left wing had 30 gun sloops and 14 gun yawls supported by 12 gun sloops and yawls from Cronstedt's brigade. The rest of Cronstedt's brigade, consisting of the turuma Norden, one galley and 36 gun sloops and yawls, was to remain in reserve and guard against a possible Russian flanking maneuver. Artillery batteries were constructed on the skerries of Kråkskär (between the center and right wings) and Sandskär (between the center and left wings). On 8 July the preparations were completed. The Russian coastal fleet consisted of nine archipelago frigates, 13 xebecs, 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. On the morning of 9 July Gustav III suddenly named Lieutenant-Colonel Cronstedt as his flag-captain after relieving Colonel George de Frese from his duties. The reason for this sudden change was likely that de Frese had been in favor of withdrawing from Svensksund to a more favorable location while Cronstedt had advocated fighting the Russians at Svensksund. ==Battle==

At 08:00 on 9 July the Russian flagship signaled the attack. By 09:30 the first ships had reached firing distance in the western flank but soon after fighting spread throughout the battle lines. The Swedish right wing under Lieutenant Colonel Törning met with increasing resistance as the Russian left wing opposing him was reinforced. However, the Swedes were able to move ships from their reserves to support their right wing with a counterattack which managed to lead the Russian left wing into disorder. The strong winds also made it difficult for the Russians to aim their guns, a problem affecting the Swedish ships much less, as the Russian ships acted as a wavebreaker in front of them. After no Russian ships were seen approaching from Fredrikshamn, the Swedes were able to release more ships from their reserves to bolster the Swedish left wing led by Lieutenant Colonel Hjelmstierna. Half of Hjelmstierna's ships were sent to the rear of the Russian fleet through a narrow passage between Legma and Kutsalö which in turn forced the Russian right wing to deploy accordingly. However, movement to the back of the line was read as a signal to withdraw by the Russian left wing which started its retreat leaving the Russian center to face the Swedes alone. in Stockholm, painting by Pehr Hilleström By the evening it had become apparent that the Swedes were victorious even though the Russian center, consisting of their galleys and largest ships, continued to fight despite unfavorable winds and battle damage. At this time the Swedes were able to fire at the Russian ships from the front as well as from both sides and several Russian ships started drifting into the Swedish battle line. Along with 21 other ships the Swedes captured the Catarina, Nassau-Siegen's flagship. The battle of Svensksund is the biggest naval battle ever fought in the Baltic Sea: 500 ships (including supply ships and other ships not involved in combat), over 30,000 men and several thousand cannons. At Svensksund, the Swedes boasted that they destroyed 40 percent of the Russian coastal fleet. ==Aftermath==

Surviving Russian ships gathered at Frederikshamn where the badly depleted fleet was being rebuilt while the Swedish coastal fleet stayed at Svensksund. The Swedes later sent a squadron of 25 gun sloops closer to Frederikshamn but they were turned back on 5 August by the rebuilt Russian coastal fleet. The Swedes withdrew back to Svensksund but the Russians did not give chase. This defeat encouraged Russia to negotiate with Sweden, eventually signing the Treaty of Värälä on 14 August 1790. Neither side gained any territory, however all provisions in the peace treaty of Nystad from 1721 that formally infringed upon Swedish sovereignty were cancelled. After the war the Russians started a massive fortification programme on the eastern, Russian, side of the Kymi river, building the sea fortresses Fort Slava, Fort Elisabeth and the land fortress Kyminlinna. The forts later grew into the port city of Kotka. The Russian frigate Sankt Nikolai was one of the ships sunk in the battle. She was found in 1948 off Kotka, almost intact. Over 2,300 objects have been recovered from her hull by divers. ==Notes==
