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.
