World War II espionage and propaganda stories are just about the richest in history. ""Operation Bernard"" and the Cicero story are two from the vast library of volumes now recounting how Allies and Axis fought the battle of words and of spies. Sefton Delmer's book is a welcome and valuable addition to such literature. Delmer, a German expert writing for British newspapers, conceived the idea of a ""Black Radio"" in 1941 to confuse and undermine the Germans in Europe. This radio station appeared to be actually German, and seemed to be broadcasting from underground sources in Europe. Known as the it promulgated the idea of a pro-Fatherland, anti-British, but also anti-Nazi movement in Germany which was trying to destroy the Fuchrer's power. The Hess flight to Scotland with supposed peace overtures to Britain gave the station special impetus. Its broadcasts reached German soldiers in the field, U-boat crews at sea, and civilians in Germany itself. As learned after the War, the broadcasts achieved a great deal in alienating the German armed forces from the Nazi Party, and in softening certain military sectors for Allied invasion. With the threats of a resurgences of militarism and anti-Semitism in Germany today Delmer breaks a long silence to explain how the myth of the ""good"" German Army vs. the ""bad"" Nazis---a myth greatly helped by his began radio station---really began. A really fascinating study in politics and propaganda, and very readable.
