Questions from this subtopic
Each one with the model answer underneath.
- 1
What was Dönitz's strategy in the Battle of the Atlantic?
Model answer
Admiral Dönitz used U-boat 'wolf packs' against Allied convoys from 1939 to sever Britain's supply lines.
- 2
Why was May 1943 a turning point in the Atlantic?
Model answer
Better radar, air cover, escort carriers and code-breaking inflicted such heavy U-boat losses ('Black May') that Dönitz withdrew his submarines from the convoy routes.
- 3
How did Enigma and naval codes matter?
Model answer
German Enigma-encrypted messages were broken at Bletchley Park ('Ultra'), helping the Allies route convoys away from the U-boats.
- 4
What was Dönitz's wolf pack strategy?
Model answer
Concentrating U-boats to attack a convoy at night on the surface, directed by radio from headquarters once a shadowing boat had found the target.
- 5
How serious was the Atlantic threat?
Model answer
Churchill said the U-boat peril was the only thing that ever really frightened him; over 3,500 Allied merchant ships were sunk during the war.
- 6
What technologies defeated the U-boats?
Model answer
Centimetric radar, high-frequency direction finding, better depth charges and Hedgehog, escort carriers, and very long range aircraft closing the mid-Atlantic gap.
