The Baltic Fleet from Peter the Great to besieged Leningrad

Peter the Great founded Saint Petersburg as Russia's western-facing capital and used foreign naval expertise to defeat Sweden, establishing Russia as a Baltic power and a principal European state. The Baltic Fleet later helped the Bolsheviks seize power when Aurora signaled the assault on the Winter Palace. Sailors who became disillusioned with the new dictatorship revolted at Kronstadt, where Bolshevik troops attacked across the frozen Gulf of Finland. British coastal forces also struck Bolshevik warships during the civil-war intervention. Finland's participation in 1941 is framed as a response to repeated Russian invasions and its constrained position between larger powers, rather than simple ideological alignment with Germany. German advances, Finnish participation, mines, nets, and winter ice confined the Soviet fleet near Leningrad, where battleship and cruiser guns still supplied valuable fire support during the siege.
