The Battle of Vyborg Bay (also known as the Battle of Vyborg) was fought between Russia and Sweden on 3 July 1790 in Vyborg Bay off the coast of Vyborg during the Russo-Swedish War of 1788–1790. The Swedish Navy suffered heavy losses, losing several ships of the line and frigates, but under Gustav III eventually managed to escape through a Russian naval blockade composed of units of the Baltic Fleet, commanded by Admiral Vasily Chichagov. British historians would later call the Battle of Vyborg Bay the "Baltic Trafalgar". The battle ranks among the world's largest historical naval battles and also among the most influential, as it introduced the naval battle concept of "firepower over mobility".
