Operation Overlord

Allied invasion that liberated German-occupied Western Europe.

Last updated

The Allied plan to create a major foothold on the continent was designated "Overlord".[1] Operation Neptune, the code-name for the initial amphibious assault and securing of a beachhead, is commonly called "D-Day".[1] Normandy was selected for the landings by the Allies; the absence of harbour facilities there was addressed by constructing artificial ports.[2]

What the cited sources add

The short operating range of British aircraft such as the Supermarine Spitfire and Hawker Typhoon greatly constrained planning.[10] A friendly fire incident on 27 April 1944 resulted in as many as 450 deaths, and the following day an additional estimated 749 American soldiers and sailors died during Exercise Tiger.[11] The Dieppe Raid demonstrated that sufficient artillery, air support, and specialized vessels capable of operating very close to shore were necessary.[10] By the end of March, the Enigma cipher used by Field Marshal Gerd von Rundstedt had been broken.[12]

After the Allied landings, the Germans altered the Enigma codes, but by 17 June the Allies had regained the ability to read them consistently.[12]
