Slaget ved Ruona (1808)

The battle of Ruona–Salmi or the battle of Kuortane was fought between Swedish and Russian troops on 1–2 September 1808 at Ruona and Salmi, Kuortane. The Swedish army was led by Wilhelm Mauritz Klingspor with 4,700, 5,000, or 5,500 men under his command (according to Russian sources, there were 8,000 Swedes or 7,000 regular soldiers and 5,000 irregular) against the Russian army of between 9,000 and 11,000 men under the command of Nikolay Kamensky. The battle turned up to be a major engagement in the war where fierce artillery fire occurred from both sides. Kamensky, advancing from Alanus, beat back the Swedish barriers and on 31 August approached the Swedish army's position near Kuortane.

Kamensky, having sent detachments under the command of Colonel Vlastov and Major general Kazachkovsky to bypass the enemy's flanks, attacked the Swedish troops on September 1 from the front by the vanguard of Russian troops under the command of Colonel Kulnev, and then by the detachment of Major general Raevsky. Despite the fierce and stubborn fight, which was held with varying success, the Swedes could not be pushed out from their positions. Meanwhile, detachments of Vlastov and Kazachkovsky bypassed the Swedish position and Klingspor, fearing being surrounded, in the night of September 2 retreated to the rear off Salmi village. In the morning Kulnev's 4,000 strong detachment defeated the Swedish rearguard and attacked the main Swedish positions from the front, while Kazachkovsky's detachment attacked from the rear. The enemy, pursued by Russian hussars, retreated in disarray to the north-west towards the town of Vaasa, unable to withstand the assault.

The Swedes, who were in a well-fortified position, lost 170 killed, 400 wounded and 110 captured according to the reports of regimental losses, in addition to more than 300 men who had fallen ill. Other Swedish sources gives 900 losses. Russian assessment suggests that Swedes lost up to 1,500 men. The Russians lost 128 killed, 648 wounded and 51 captured (excluding 18 officers), according to their own estimates. According to Russian general Paul van Suchtelen, the losses reached almost 2,000 in total, with an equal amount on both sides. This battle is considered one of the turning points in the Finnish War along with the battle of Oravais.

Ruonan taistelu käytiin Kuortaneella, Ruonan ja Salmen alueella, Suomen sodan aikana 31. elokuuta ja 2. syyskuuta 1808 välisenä aikana. Taistelua pidetään Oravaisten ohella sodan ratkaisseena yhteenottona, joka nujersi Ruotsin armeijan taistelutahdon.

Ruotsin joukot olivat jatkaneet kesähyökkäystään Alavuden taistelussa 17. elokuuta saavuttamansa voiton jälkeen. Venäläisten saamat vahvistusjoukot ja sotamarsalkka Wilhelm Mauritz Klingsporin varovaisuus kuitenkin tekivät saavutukset tyhjiksi. Elokuun lopussa Carl Johan Adlercreutzin johtamilla suomalais- ja ruotsalaisjoukoilla oli vastassaan 21 200 venäläissotilasta. Adlercreutz oli jo Alavuden taistelun jälkeen antanut kenraalimajuri Hans Henrik Gripenbergille käskyn valmistella puolustusasemat Ruonan kylään Kuortaneella. Asemat olivat kuitenkin alkeellisista risumurroksista valmistetut, joiden tehoa yritettiin parantaa asettelemalla tykkejä tasaisin välein pitkin linjaa.

Slaget vid Ruona var ett slag under finska kriget 1808–1809. Slaget stod mellan svenska och ryska styrkor den 1 september 1808.
