During the French Revolutionary Wars, the Black Sea Fleet was initially deployed under the command of Admiral Ushakov, in conjunction with the Turks, against French forces during the Siege of Corfu. The victory led to the establishment of the Septinsular Republic with the island of Corfu then serving as a base for Russian naval units in the Mediterranean operating against the French. Subsequently Turkey, encouraged by the French, went to war with Russia in the Russo-Turkish War of 1806-1812. The Russian fleet (deploying from the Baltic, but joining some vessels of the Black Sea Fleet already in the Mediterranean prior to the outbreak of war) under the command of Admiral Dmitry Senyavin played an instrumental role in this conflict securing victories at both the Battle of the Dardanelles (1807) and the Battle of Athos.
