Four torpedoes left their tubes and vanished into the Arctic water. Captain Nikolai Lunin, commanding the Soviet submarine K-21, listened through the hull for the sounds that would tell him whether he had just changed the course of the war. He heard explosions. What he could not see -- submerged at periscope depth in the perpetual daylight of a polar July -- was whether they struck the most feared warship in the Norwegian Sea. It was 5 July 1942, and the German battleship Tirpitz was steaming north with a powerful squadron to annihilate convoy PQ-17. What happened next became one of the most contested episodes in Soviet naval history: a story of courage, propaganda, and the fog that settles over truth in wartime.

K-21 was lurking at 20 meters depth when hydroacoustician A. Smetanin detected propeller noise at 16:30. Atmospheric refraction over the Arctic sea played tricks with visibility -- Lunin initially mistook the distant masts of the German fleet for a surfaced U-boat, then for two t...
