One man could have enabled the most audacious terrorist threat against America prior to 9/11 and helped the Nazis win World War II-the Nazi spy pastor, Carl Krepper. His riveting story brings to light a forgotten chapter in the history of the Second World War.As America continues to wrestle with issues surrounding the threat of sabotage and terrorism, this eye-opening work details a very real threat faced by our country in the Second World War, and the key aspects of the underground war that was fought in this country by Nazi agents. The Nazi Spy Pastor: Carl Krepper and the War in America presents the fascinating true story of a secret plot to be executed on American soil-a German sabotage operation with intended targets in New York, New Jersey, Pennsylvania, Tennessee, and Illinois. This book chronicles, for the first time, the remarkable life of Carl Krepper-naturalized American citizen, Lutheran pastor, and the Nazi deep-cover operative who could have made possible the greatest terrorist threat on American soil prior to the attacks on September 11th. Historian J. Francis Watson draws on newly declassified archival and documentary materials to tell the full story of how a devoted clergyman lost his way and betrayed his calling, instead advocating an ideology that supported genocide and the deaths of innocent victims in America, and how he came to play a key role in the Pastorius sabotage plot. The book covers fascinating cloak-and-dagger details of submarine infiltrations, safe houses, and secret codes, detailing Krepper's life, his work as a Nazi agent, and the FBI sting operation that finally brought about his arrest in December of 1944. This little-known, real-life espionage story will serve students of World War II history and appeal to readers interested in immigration and the integration of immigrant populations as well as the histories of New York and New Jersey.
