The Battle of Sävar was fought on Saturday, 19 August 1809, between Swedish and Russian forces, during the Finnish War; it was the last pitched battle to be fought in Sweden. After the Russian conquest of eastern Sweden in 1808, the Swedish forces retreated to actual Sweden. In March the following year, Russian emperor Alexander I launched a threefold attack on Sweden, to force the country into the Continental System and to cede Finland to the Russian Empire; despite early advantages at Kalix and the Åland Islands, the attack failed to achieve a quick ending to the war. After further campaigning in northern Sweden, with battles such as Skellefteå and Hörnefors, the Russian forces under Nikolay Kamensky occupied all of Västerbotten by June.
The Battle of Revolax took place on 27 April 1808 at Revonlahti, in Northern Ostrobothnia, Finland, when the Swedish supreme commander Wilhelm Mauritz Klingspor and the Savolax brigade under Colonel Johan Adam Cronstedt, a total of about 2,250 Swedes surprised an isolated Russian column of about 1,700 men under Major General Michail Leontievich Bulatov. The Russians were surrounded and tried to cut their way through but failed and the Russian general Bulatov was taken prisoner by the Swedes.
The Battle of Oravais from September 14 until September 15 was one of the decisive battles in the Finnish War, fought from 1808 to 1809 between Sweden and the Russian Empire as part of the wider Napoleonic Wars. Taking place in modern-day Vörå in western Finland, it is sometimes regarded as the turning point of the Finnish War: the last chance for Sweden to turn the war to her advantage. It was the bloodiest battle of the conflict, along with the Battle of Sävar, which some historians attribute to the exhaustion, resignation and desperation of the Swedish army: it was losing the war, and defeat led to its loss of Finland to Russia.
The Battle of Jutas was fought on Tuesday, 13 September 1808 between Swedish and Russian troops south of Nykarleby in Ostrobothnia, Finland. Before the battle the Swedish army was in retreat after the campaign of the previous summer. The main Swedish force was retreating from Vaasa to Nykarleby. The Russians sent a force to cut off the Swedish retreat. In response the Swedes sent a force under Georg Carl von Döbeln to intercept them. The battle ended in a Swedish victory, but the main Swedish army was beaten in the Battle of Oravais the very next day.
The Battle of Koljonvirta i.e. the Battle of the Virta Bridge, also known as the battle ofIdensalmi, was fought between Swedish and Russian troops on October 27, 1808. The Swedish force consisted of troops from Savolax and Östergötland. After the main Swedish army had been defeated at the Battle of Oravais the army under Johan August Sandels in Savonia had to retreat in order not to be outflanked by the Russians. Sandels found a good defensive position north of Idensalmi and decided to resist the Russian advance there.
The Battle of Pyhäjoki was a retreating action fought on 16 April 1808, at Pyhäjoki in Northern Ostrobothnia during the Russian–Swedish war of 1808–09. The winter made the operations more difficult and the battle of Pyhäjoki became one of the first skirmishes to be fought after the Swedish retreat stopped. The Russian army had been following the Swedish army to the north. At the same time, they had left large portions of Finland to be occupied by the Russians. Yakov Petrovich Kulnev led a vanguard of 1,300 men — his army counted 4,000 men in total — and caught up with the rearguard of the retreating Swedish main army at the village of Ypperi. Skirmishes occurred all the way to Pyhäjoki, where the Swedes made a brief stand, before Wilhelm Mauritz Klingspor gave orders to von Döbeln and Gripenberg to continue the retreat to follow the original strategic plan. The Swedes had checked Kulnev's attack with about 2,000–2,500 men, however, as the Swedes fought a retreating battle, only one battalion at the time could go up against the Russians for most of the fighting. They had lost 183 men in killed, wounded and captured. Kulnev had lost 71 men at Pyhäjoki alone but probably around double that number when applying the losses from the fighting at Ypperi towards Pyhäjoki.
The Battle of Nykarleby was fought between Sweden and the Russian Empire during the Finnish War of 1808–1809.
The Helsinki village landing, or the Combat of Helsinge, was fought during the Finnish War between Sweden and the Russian Empire on 26–28 September 1808, a part of the battles of the Turku archipelago.
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 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.

The Åland Offensive was part of a threefold attack on native Sweden by the Russian Empire during the Finnish War, to force Sweden into the Continental System and to give up Finland. Åland was to be used for an immediate attack on Stockholm. Only minor skirmishes occurred when Gotthard Johann von Knorring launched his Åland offensive on 10 March 1809, since the Swedes under Georg Carl von Döbeln quickly withdrew over the ice to Stockholm. Although suffering heavy casualties, the Swedish army had escaped destruction. The concluding Convention of Åland not only brought an end to the Russian offensive, but led to their withdrawal from the islands.
The Capitulation of Kalix took place during the Finnish War, on 25 March 1809, when 3,800–4,500 Swedish and Finnish troops under Hans Henrik Gripenberg surrendered to a much larger Russian army under Pavel Andreyevich Shuvalov, as part of a large Russian threefold attack against Sweden. The capitulation was characterised by the Swedish High Command as treacherous and Gripenberg was soon court-martialed.
The Battle of Skellefteå took place during the Finnish War, on 15 May 1809, when 6,000 Russians under Pavel Andreyevich Shuvalov attacked 700 Swedes under Johan Henrik Furumark, at Skellefteå, Sweden. The Swedes, who fought a delaying action to buy time for their provisions to be escorted to safety, were captured as the Russians flanked around and cut-off their way of retreat. Most provisions, however, were saved.
The Battle of Hörnefors took place during the Finnish War, on 5 July 1809, when 2,400 Swedes under Johan August Sandels went on a counter-offensive against 3,350 Russians under Ilya Alekseyev and Pavel Andreyevich Shuvalov, at Hörnefors, Sweden. After more than two hours of intense fighting along the Hörnån (river) Sandels ordered a retreat, after having been misinformed of a greater Russian flanking attack.
