Finnish Supreme HQ ordered the Ladoga Freshwater Navy to re-form the Ladoga Navy on Aug 2 1941. At the time the unit consisted of two small tugs, four prams and 150 motor boats. Staff of the unit was positioned to the Sortavala city, where the HQ of the Ladoga Defence already was while the service elements were positioned to the Rauhala village, Lahdenpohja municpality. Interesting detail: the predeseccor, Freswater Navy, had four flotillas, each one having two tugs armed with 47-75 mm guns and four motor boats operated by 800 men.
Motorboats participated the Markatsimansaari Island invasion on Aug 16-17 and the Rahmansaari Island invasion on Sep 7-10 1941. When the Ladoga Defence was renamed as the Ladoga Coastal Brigade the Navy was renamed as the Naval Detachment of the Ladoga. Unit's main responsibilities were guarding and supplying the troops postioned on the islands of the lake. The capturing of the Latvian merchant vessel Ilga from the Mantsinsaari Island's harbor was very welcomed on Sep 22 1941. That 211-ton ship was renamed as Aunus.
According to the terms of the Moscow Peace Treaty agreed on March 13 1940 had forced the Finns to cede all their territories on the south-west-north coasts of the Ladoga and before leaving the harbors all boats etc. were sunk. During the late 1941 all of them were localized for their future salvage in 1942.
In the beginning of 1942 the Soviet ships were positioned to the Mostra, Osinovets and New Ladoga harbors. The Finnish intelligence had estimated the strength of the enemy navy being 10 gunboats, 30 minesweepers, 20 guard motor boats, 20 tugs and a huge amount of motor boats and prams.
Commander of the Ladoga Coastal Brigade, Col. Järvinen, suggested in the spring of 1942 that the Finnish Airforce should increase their raids against the enemy and that the Navy should issue some motor torpedoboats. Eventually, that didn't occur, but instead the Germans pressed some 2500-men strong unit to serve there, being equipped with 21 Siebel (heavy), smaller gun ferries and mine boats (KM boot). Four KM boats arrived on July 8 and the ferries during the month.
Also the Italians wanted (or were ordered?) to participate, so four MAS torpedoboats were shipped from Spezia to Szczecin, from where they sailed to the Saimaa canal, ending up to the Punkasalmi municipality and eventually to the Lahdenpohja harbor. All Italian boats, unit commanded by Capitano di corvetta Giuseppe Bianchini, were waiting orders in the Port of Sortanlahti on June 22. Interestingly, boats MAS-526-529 were the same which the Finns had bought in 1939-1940, but the shipment was captured by the Germans due the Molotov-Ribbetrop Pact and returned to Italy.
The eagerly waited successful naval operations stayed missing, though. The Italians assaulted 20 times, managing to sunk two vessels. German mine boats (KM boot) suffered engine problems, being able to make one mine laying sortie with three boats in the late September. The gun ferries, being clumsier and slower than the Soviet ships and lacking air support, were unable to operate. When getting the Luftwaffe Detachment Philipp positioned onto the Petäjärvi airfield, Karelian Isthmus, on the early August and after having informed that some enemy gunboats were sunk, the ferries started operations. A total of seven assaults were made but the enemy was engaged only three times.
The largest German-Italian-Finnish naval operation was the Suho Invasion on Oct 21-22, main targets being the destruction of the light house and all coast artillery batteries. 16 ferries and seven infantry boats participated. The operation, however, was a total disaster. The Germans lost four ferries, at least one boat and 61 men fallen and wounded.
No wonder that a Finnish Navy officer Eino "Saunateufel" Pukkila named the chapter describing the naval operations on the Lake as *Antic on the Lake Ladoga" (Ilveilyä Laatokalla) in his book Taisteluhälytys.
SA-kuva pics show some vessels and aircraft (except the Heinkel, I'd say) of the units mentioned. The bomber was used as an air support, though.
