The early 19th century was a time of upheaval, which saw the 1808–1809 war between Sweden and Russia, as well as a devastating fire in 1835 that destroyed approximately half of the city. Despite this, the economic progress continued, and a brewery, a matchstick factory and several banks were founded after 1850. In 1859, the merchant and shipowner Peter Malm started a steam powered sawmill, which was only the second such installation in Finland. The Crimean War was a major setback to shipping industry, as the British navy puts up an effective blockade and the shipping fleet in Jakobstad during the Åland War was reduced from 26 ships to 9.
