Finnish Ladoga Naval Detachment Germany transferred four MAL-type ferries - "M-31", "M-32", "M-33" and "M-34" - originally intended for use on Lake Peipus, to the Finns on Ladoga. The Finnish Navy also transferred several small run-down naval vessels to the lake, the motor torpedo boats "Syöksy", and "Vinha", which were no longer in adequate condition to carry torpedoes. Lake remained mostly quiet until Soviet offensive of 1944 started. While Finnish naval forces on the lake remained passive during the Soviet landings at Tuloksa on 23 June they did play key role in facilitating the Finnish evacuations from the eastern shore of the lake Ladoga.
