The Wolfpack 水下地狱 1 4 1207067 8.0 1 0 The wolfpack tactic was made famous by Admiral Karl Donitz, Hitler's mastermind of submariners. His strategy: to send teams of U-boats to bear against the convoys of ships heading from Canada to Britain, cut maritime lifelines, and starve the enemy into defeat. Take a deep dive into the North Atlantic as we go above and below sea level to relive one of the first attacks of Donitz's lethal subs in 1940, headed by leader of the pack Commander Otto Kretschmer. Then follow Britain's war strategists as they race to combat this new deadly attack. 45 https://image.tmdb.org/t/p/original/zWEDIDQIqzA8oKeOsrN4hhkZgRX.jpg 2016-04-26 2016-04-26 false 0 National Geographic Smithsonian Channel Parallax Film Productions Maija Leivo Ian Herring Paul Snider German Officer https://www.themoviedb.org/person/1652757 1652757 Patrick Truelove Admiral Ernie King https://www.themoviedb.org/person/1652758 1652758 Matthias Brunert Naval Officer https://www.themoviedb.org/person/1652755 1652755 2025-09-23 16:07:32 UNKNOWN NONE S01E04.strm
