"The Ahvenanmaa Islands in the Gulf of Bothnia contain the ruins of Bomarsund, a Russian fortress built partly by Jewish military conscripts and destroyed by British and French naval forces during the Crimean War in 1854. Nearby are the graves of a number of Russian-Jewish soldiers (conscripts)." Source: Freedman, Warren. World Guide for the Jewish Traveler. NY: E.P. Dutton Inc, 1984, p. 100. [1994].
