The literature on German intelligence operations is growing. Out of the diary kept by Major General Ewin von Lahousen-Vivremont, right-hand man of Admiral Canaris -- the German secret service chief-, comes the account of espionage and sabotage activities in the United States, South Africa and European countries. The secrets of the Abwehr as recorded by Gunter Peis and Charles Wighton include operations which were foiled at their inception and others which were not frustrated until considerable damage had been wreaked. The theft of the American Air Force bombsight by a devoted patriot and the subsequent counterspy parry; Operation Pastorius and the nine men who landed fresh from the training school on the shores of Massachusetts; the South American boxer Robey Liebbrandt, an Afrikaner, who planned sabotage in South Africa; the two Danes in England via parachutes... here are the details of the activities and the men who were tried at Nuremburg. The informal approach coupled with highly interesting subject matter may appeal to readers of World War II records.
