Ways to Avoid Losing Oxygen in a Submarine
In 1940, German U-boat commander Otto Kretschmer's submarine was under siege for hours and his crew grew tremendously stressed. In order to preserve oxygen, they had to find ways to stay calm.
More About This episode
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.
