If an echo was detected, and if the operator identified it as a submarine, the escort would be pointed towards the target and would close at a moderate speed; the submarine's range and bearing would be plotted over time to determine course and speed as the attacker closed to within 1,000 yards (910m). In all, 43U-boats were destroyed in May, 34 in the Atlantic. The Battle of the Atlantic, 1939 to 1945. ASDIC was effective only at low speeds.

[104] A history based on the German archives written for the British Admiralty after the war by a former U-boat commander and son-in-law of Dnitz reports that several detailed investigations to discover whether their operations were compromised by broken code were negative and that their defeat ".. was due firstly to outstanding developments in enemy radar"[105] The graphs of the data are colour coded to divide the battle into three epochs before the breaking of the Enigma code, after it was broken, and after the introduction of centimetric radar, which could reveal submarine conning towers above the surface of the water and even detect periscopes. To counter this, the crewmen were issued with an 'MN' lapel badge to indicate they were serving in the Merchant Navy. With the battle won by the Allies, supplies poured into Britain and North Africa for the eventual liberation of Europe.

The Allies won because they had radar which allowed them to sense the U-boats. [45] Her sinking marked the end of the warship raids. On November 19, 1942, Admiral Noble was replaced as Commander-in-Chief of Western Approaches Command by Admiral Sir Max Horton.
