Soviet Union had detonated an atomic bomb.

Norway. The huge waves slammed the submarines' snorkel so violently, and jolted the boat so severely, that the pounding caused an electrical fire and battery explosion, followed by the release of deadly
hydrogen gas. Defying the most wretched weather conditions, men of ''Cochino'' and ''Tusk'' fought to save the submarine for 14 hours, performing acts of skillful seamanship and high courage in the storm-lashed, frozen seas. A second battery explosion on 26 August, however, made "Abandon Ship" the only possible order, and after the crew made a dangerous rope transfer to ''Tusk'', the abandoned ''Cochino'' sank at .
