Vidlitsa-Tuloksa landing operation and its role in halting white Finnish intervention in Southern Karelia

The article highlights the events of the Civil War and military intervention in the North-West of Russia in the spring and summer of 1919. Having studied archival documents and memoirs sources, the author tells about the preparation and conduct of the landing operation against the White Finnish troops on the eastern coast of Lake Ladoga in the area of Vidlitsa and Tuluoksa settlements by the Red Army command. On June 27, 1919, the units of the First Infantry Division of the Red Army (under the command of M. P Gusarov, the Chief of the Division and Commander of the Interlake District) together with the ships of the Baltic Sea naval forces and the Onega military flotilla (under the command of E. S. Pantserzhansky) destroyed the base of the Olonets volunteer army, which was used by Finland’s military and political leaders for personnel replacement, as well as for the supply of arms, ammunition, food, and other material means. The operation timeline was minutely traced, the events were reconstructed, and the historiography of the topic was refined significantly. In conclusion, it is emphasized that as a result of the landing operation the operational situation in the isthmus between Lake Onega and Lake Ladoga changed in favor of the Red Army, the threat of Petrozavodsk being captured was eliminated, and the control over the sovereign territory of the Russian Soviet Federative Socialist Republic on the eastern coast of Lake Ladoga was restored.
