Battle of Bomarsund

The Battle of Bomarsund, in August 1854, took place during the Åland War, which was part of the Crimean War, when an Anglo-French expeditionary force attacked a Russian fortress. It was the only major action of the war to take place at Bomarsund in the Baltic Sea.Bomarsund was a 19th-century fortress, the construction of which had started in 1832 by Russia in Sund, Åland, in the Baltic Sea. Bomarsund had not been completed . When the war broke out the fortress remained vulnerable especially against forces attacking over land. Designers of the fortress had also assumed that narrow sea passages near the fortress would not be passable for large naval ships; while this assumption had held true during the time of sailing ships, it was possible for steam powered ships to reach weakly defended sections of the fortress.
