First of all, I thank my long-suffering wife Donna for proofreading and helpful suggestions. I also thank Frank Tugwell (who has a true understanding of Hitler and the Third Reich) for his help with computer operations and the final production of the manuscript. Thanks also to Dr. John C. Lewis for his help and advice. Special thanks to my in-laws, Don and Wanda Pounds of Nashville, Arkansas, for letting me use their "summer house," where I could work in isolation. I also express my gratitude to Dr. Gene Mueller of Henderson State University, to Dr. John T. Morgan of Emory and Henry, and to Wayne D. Shows for their assistance in various projects, and to Friedrich von Stauffenberg for giving me his papers shortly before his death. I also thank Dr. Sidney Jumper, Dr. Charles S. Aiken, and the Department of Geography at the University of Tennessee; and Lieutenant Colonel Ernest Bruce, Department of Aviation, Northeast Louisiana University, for preparing me to work at this level. As usual, thanks to the United States Military History Institute at Carlisle Barracks, Pennsylvania, the Still Photo Division of the U.S. National Archives, and the staff of the Bundesarchiv/Kolbenz, for providing materials and/or photographs. Gratitude is also expressed to Princess Cruises, which gave me the opportunity to visit Normandy and the various landing beaches in the summer of 1994. Last but not least, thank you to Melinda Matthews, interlibrary loan librarian at Northeast Louisiana University, for the fine job she did in locating and obtaining materials, some of which were difficult to find.
