It was in this part of the war, which greatly troubled Britain. In this sea battle, communications from both sides were encoded to stop eavesdropping. Unknowing to the British was that the Germans had already cracked the Royal Navy’s codes before the war even began. This allowed them to constantly to read British messages. Thus they knew where British ships would be and consequently be able to sink them with their U-boats. The U-boats were a serious problem for the British, with Winston Churchill saying, ”The only thing that ever really frightened me during the war was the U-boat peril.” It was here that British suffered greatly during the early periods of the war. When Britain was in short supply of goods such as ammunition, they needed to get imports from the USA. This proved futile when their cargo ships were sunk by U-boats, which hunted in “wolf packs”. This all changed, however, once enigma was broken, the operation of the continued breaking of the enigma codes was called Ultra. The British now knew where the U-boats were and could now navigate their ships away from them. By the time enigma was broken, the allies had everything they needed to fight the Battle of the Atlantic. This included: radar, sonar, improved depth charges and long-range aircraft. All of this was maximized by the decrypted work. The allies were able to zero in on the U-boats. By May 1943, the amount of U-boat losses was so great that German Admiral, Karl Dönitz, withdrew them from the North Atlantic. Military historians Allan R. Millet and Williamson Murray both said, ”Ultra’s contribution to the antisubmarine battle now became the most significant intelligence victory of the war, and the only episode in which intelligence alone had a decisive
