The story of espionage is as old as military history. The clandestine services weren’t always so respected however. I speculate that had the German forces and their leaders agreed to the importance of spy work, World War II would have come out vastly different. Thanks be to whatever reasoning they had, that they thought the way they did. I recommend David Khan‘s Hitler’s Spies as a read on that topic.
Another interesting point about World War II spies…They were all over the United States. I remember teachers, and even textbooks, touting American invulnerability; that no enemy had set foot on American Soil since – what was it? The French and India War. Technically, the Civil War should hold that title if we’re not including enemies in secret service. This can easily be proven wrong by anyone studying up on World War I and World War II. Both wars served the States a goodly helping of enemy eyes on American soil. Helluva Town: The Story of New York City During World War II by Richard Goldstein reminds us of the round up of ‘suspect aliens’ moments following the attack on Pear Harbor: Italian, German and Japanese. Goldstein tells us how they were detained and why in the city of New York.
