After Operation Valkyrie—the failed July 20, 1944, plot to assassinate Adolf Hitler and seize control of the German government—both the Third Reich and Hitler came to a violent end. Hitler promised a classless fatherland before he became chancellor and had covertly been liquidating Germany's elite officer corps long before Stalingrad. Today it is possible to reconstruct and connect important events and biographies of the principle characters to chronicle the disappearance of Germany's officer class, its nobility and, for a time, its civilian leadership.
