Built as a fishing boat in 1931, Туман (Tuman; Mist or Fog) was commandeered by the Soviet Navy on 19 October, 1939. He was given a pair of 45mm guns, two machine guns, and some depth charges, and told to go patrol the Barents Sea. This was done successfully until 10 August, 1941, when Tuman ran into three German destroyers. Tuman reported the contact, then began evading and laying smoke. Tuman was hit repeatedly, and was unable to return fire after his stern 45mm gun was disabled. Belated support from shore batteries drove off the Germans, but Tuman sank with the loss of fifteen of his fifty-two crew.
