Carl Olof Cronstedt

Carl Olof Cronstedt the elder was a Swedish naval commander responsible for the overwhelming Swedish victory at the Second Battle of Svensksund, one of the largest naval battles in the history of the Baltic Sea. He is often better remembered, however, as the commander of the fortress of Sveaborg during the Finnish War in 1808–09, which was fought between Sweden and Imperial Russia, and ended in Cronstedt surrendering the fortress.
