Kola Bay
Ships were lost fighting against unequal odds. Patrol boat "Tuman", a former trawler, was sunk by three Kriegsmarine destroyers at the entrance to Kola Bay on August 4, 1941. The icebreaker "Sibiryakov" was sunk on August 25, 1942 by the German pocket battleship "Admiral Scheer" while defending two convoys. The patrol ship "Brilliant" (formerly trawler "Murmany") was sunk by a submarine.
