On August 8, 1944, when Himmler appointed SS General Kammler Commissioner General for the A-4 program, it looked as though the struggle for control had come to an end. I felt like a man who has devoted years of toil and affection to making a superb violin, a masterpiece which needs only tuning, and who then has to look on helplessly while the instrument is grabbed by a tough, unmusical woodman and scraped with a jagged lump of wood.
