Oscar Koch’s sterling performance as General George S. Patton Jr.’s intelligence chief, G-2, was a critical element in Patton’s success in World War II and earned Koch the reputation as arguably the best intelligence officer in U.S. Army history. Koch went on to help overhaul the CIA and, in retirement, earned a coveted Guggenheim Fellowship to support research and writing on intelligence in combat. His unlikely friendship with Robert Hays, a young journalist who also happened to be a veteran of Koch’s beloved U.S. Third Army, led to a book that has become a crucial source for military historians. Now, Robert Hays offers a deeply personal account of their relationship, reveals the general’s astonishingly gentle and caring nature, and describes Koch’s philosophy and concerns about the intriguing field of intelligence. He details Koch’s stunning forecasts of an enemy offensive weeks before the Battle of the Bulge, and how Koch set the standard for using ULTRA, the highly secret British intercepts of German radio, as a source. Overarching all, though, is the poignant story of Koch’s valiant battle with terminal cancer. The reader will understand why Hays grants Oscar Koch the eminent rank of personal hero and feels obligated to help assure his place in history.
