  1. 2 March 1808 – 3 May 1808

    Siege of Sveaborg

    Battle · Suomen sota · 3,2 km

    The siege of Sveaborg was a siege by Imperial Russian forces of the sea fort of Sveaborg (Finnish: Suomenlinna), off the coast of Helsingfors (Helsinki); at the time Finland was part of the Kingdom of Sweden. It took place in the spring of 1808, during the Finnish War. Despite its formidable reputation as "the Gibraltar of the North", the fortress surrendered after a siege of two months. As its capitulation was followed by the rapid collapse of Swedish resistance elsewhere, and ultimately the Russian conquest of Finland, the siege is often regarded as the decisive battle of the war.

    == Preparations == A week before the war began, Sveaborg's commander Admiral Carl Olof Cronstedt received a letter from the King Gustav IV Adolf which required him to fit for operations and acquire crews for two hemmema-type archipelago frigates and over 70 smaller gunboats or yawls. Additionally, the letter demanded that the fortress of Sveaborg must be defended to the bitter end and should withdrawing from the fortress be necessary then the bulk of the coastal fleet which had been docked at the fortress for the winter as well as all the supplies had to be destroyed by burning them down.

  2. 7 August 1855 – 9 August 1855

    Battle of Suomenlinna

    Battle · Krimin sota · 3,1 km

    The Bombardment of Sveaborg, also known as the Battle of Sveaborg, took place on 9–11 August 1855, between Russian defenders and a joint British–French fleet during the Åland War, a Baltic Sea theater of the Crimean War. British and French ships bombarded the Russian fortress of Sveaborg from beyond the range of the defenders' artillery. After 48 hours of bombardment, the attackers withdrew without attempting a landing.

    == Background == Constructed during the Swedish rule of Finland in the 18th century, the Fortress of Sveaborg (known as Viapori in Finnish, and renamed Suomenlinna in 1918) was the main defensive installation in the Grand Duchy of Finland. After the capital of the Grand Duchy of Finland was moved from Turku to Helsinki in 1812 the value of Sveaborg only increased. However, by the Crimean War the artillery of the fortress had already become obsolete. After the engagements of 1854 Russians (and Finns) expected an attack on Sveaborg in 1855. The small skirmishes that had been fought along the coast between Russian and British-French forces in the early summer of 1855 only worsened the fear while bulk of the Russian fleet had become isolated and surrounded in the port and fortress of Kronstadt off Saint Petersburg.
