COUNTERING HITLER’S SPIES British Military Intelligence 1940–1945

Lays out Germany’s attempts to breach Fortress Britain and lay bare her secrets. Spies who worked for MI5, especially those who had initially worked for the Germans, carried out sterling work which resulted in the saving of thousands of Allied lives. The success of the D-Day landings at Normandy, for example, was in part due to the excellent work of a double agent, who helped convince Nazi Germany that the Allied invasion of Europe would take place across the English Channel, at Calais.
