Naval Detachment K
Naval Detachment K () was a Finnish military detachment—specifically, a flotilla that operated on Lake Ladoga during World War II. Background The Continuation War began in the summer of 1941. The Finns, who had operated naval units on Lake Ladoga before World War II, began reestablishing a flotilla on the lake as soon as their troops reached its shores early on in the war. The headquarters was formed in Läskelä on 2 August 1941 and by 6 August, 150 motorboats, two tugs (used as minelayers) and four steam ferries had been transferred there. The tugs and ferries were equipped with 47 mm guns and machine guns. The Finns also established a number of coastal batteries on the shores and islands of Lake Ladoga. The only "true" Finnish warship on Lake Ladoga at that time was the obsolete ex-motor torpedo boat Sisu. As the Finnish land forces advanced, new headquarters were established in the captured towns along the shores of Ladoga. The Ladoga flotilla's headquarters was eventually moved to Sortavala and the harbour at Lahdenpohja became its primary base of operations.
