This is the true story of the Jewish American spies that risked it all to parachute behind enemy lines to fight back against Nazi Germany during World War II. An incredibly well-written book about Operation Greenup – the Allied top-secret effort to secure intelligence about the Nazi's underground fortress compound, or "Alpine Redoubt," within the Austrian mountains.
Towards the end of the war, American intelligence services began hearing credible rumors that, with the fall of Germany and the Third Reich inevitable by late 1944, the Nazi regime was planning one last defensive stand in an underground fortress under construction within Austria. The secret Allied Office of Strategic Services (OSS) was tasked with recruiting the men who would parachute deep behind enemy lines in Austria in order to gather intelligence on the Alpine Redoubt as undercover spies. Five brave Jewish men were chosen to lead the fight, in three daring missions known as Dania, Dillon, and Deadwood. This book mostly focuses on the Deadwood Mission and the two heroic men who led it, Frederick Mayer and Hans Wynberg. Their story is a gripping and suspenseful one, and one that every American today should read. In the closing days of the war in Europe, Mayer and Wynberg's quick decision-making could very well be credited with potentially saving thousands, if not hundreds-of-thousands of lives. Another intensely researched masterpiece by Patrick O'Donnell that I highly recommend. A real life Inglourious Basterds.
