Did the American Government and President Franklin Delano Roosevelt have advance information about Japan s attack on Pearl Harbor and was this fact later suppressed, either to conceal incompetence or because the President wanted an act of aggression to force America into war with the Axis Powers? For decades, professional and amateur historians alike have scrutinized the voluminous and sometimes contradictory trail of evidence surrounding this historic and tragic event to find an answer. One of the most written-about pieces of this historical puzzle is the so-called West Wind Execute message,...

Identifies and presents a thorough account of German intelligence organizations engaged in clandestine work in South America, and a well researched, detailed report of the U.S. response to the perceived threat. This perception was, as Mr. Mowry alludes to in his conclusions, far greater than any actual danger.

For historians and many members of the informed public, the Japanese attack on Hawaii provoked "the never-ending story." Multiple official investigations and private historical inquiries into the attack and its background have generated enormous stocks of information about both the American and Japanese sides. It may well be that we know as much about December 7, 1941, as we do about any event in the last century, the Kennedy assassination possibly excepted. However, even with this virtual mountain chain of data, information gaps still exist, and many important questions remain under...

This is the first of a two-part history of German clandestine activities in South America in World War II. In this first volume, the author, Mr. David Mowry, identifies and presents a thorough account of German intelligence organizations engaged in clandestine work in South America, and a well-researched, detail report of the U.S. response to the perceived threat. This perception was, as Mr. Mowry alludes to in his conclusions, far greater than any actual danger. Mr. Mowry's conclusions, in general, are somewhat understated. It seems fairly clear from the evidence that the Germans never...

Along with breaking the Japanese diplomatic cryptosystem, usually referred to as "PURPLE," probably the greatest example of Allied cryptanalytic success in World War II was breaking of the German Enigma machine. This cryptodevice was used by all of the German armed forces as the primary cryptosystem for all units below Army level or the equivalent. As D-Day approached, other German cryptodevices, the SZ-42 and the various T-52 machines, assumed great importance since they were used by the higher commands of the German armed forces. Many references to these German machines in the histories...
