was probably a result of the frustration the Russians felt because of intensive guerilla activity against them in the region.
On June 30, the Russian forces withdrew from Vaasa, and all officials that had pledged allegiance to Russia were discharged, and some were assaulted by locals. On September 13, the Russian forces returned and on the next day the decisive Battle of Oravais, which was won by Russia, was fought some 50 kilometers (30 mi) further north. By winter 1808, the Russian forces had overrun all of Finland, and in the Treaty of Fredrikshamn (September 17, 1809) Sweden lost the whole eastern part of its realm. Vaasa would now become a part of the newly formed Grand Duchy of Finland within the Russian Empire.
The Court of Appeal, nowadays the Church of Korsholm, survived the fire of 1852
Town fireThe mainly wooden and densely built town was almost utterly destroyed in 1852. A fire started in a barn belonging to district court judge J.F. Aurén on the morning of August 3. At noon the whole town was ablaze and the fire lasted for many hours. By evening, most of the town had burned to the ground. Out of 379 buildings only 24 privately owned buildings had survived, among them the Falander–Wasastjerna patrician house (built in 1780–1781) which now houses the Old Vaasa Museum.
The Court of Appeal (built in 1775, nowadays the Church of Korsholm), some Russian guard-houses along with a gunpowder storage and the buildings of the Vaasa provincial hospital (nowadays a psychiatric hospital) also survived the blaze. The ruins of the greystone church, the belfry, the town hall and the trivial school can still be found in their original places. Much of the archived material concerning Vaasa and its inhabitants was destroyed in the fire. According to popular belief, the fire got started when a careless visitor fell asleep in Aurén's barn and dropped his pipe in the dry hay.
