The book, Operation Valkyrie - The German General's Plot Against Hitler, represents one of the most authoritative books on this subject.  While many are aware of the July 20, 1944 attempt to kill the Adolf Hitler at "Wolf's Lair", the German Dictator's East Prussian command headquarters, few if any other accounts of the planning and execution of this plot include information from as direct a source as this book utilizes.  To be more specific, General Adolf Heusinger who was the operations chief of the German general staff from 1940 to July 20, 1944, actually survived both the assignation attempt on Hitler and ultimately the war.  General Heusinger during the four years as operations chief attended over six hundred meetings where Adolf Hitler was present.  His insight into the general mood of the officer staff and his recollections of many other meetings involving Adolf Hitler and others were documented with notes and original meeting minutes shortly after the end of the war.  Where possible, the authors of this book crosschecked figures provided by General Heusinger and found them to be both clear and concise.  While the story of the July 20th rebellion which represented the only serious attempt to destroy the much vaunted "Third Reich" from within has inspired the imaginations of novelists and popular historians for decades after the end of World War II, this book represents perhaps the most accurate picture of the how and why behind "Operation Valkyrie - The German General's Plot Against Hitler".  The major sections of this book are as follows: 1) Acknowledgments; 2) Preface; 3) July 20, 1944 - The Wolf's Lair; 4) July 20, 1944 - Paris; 5) 1934-1935 - The Army Swears Fealty; 6) 1936-1937 - "They Call Him Hermann"; 7) 1938 - " A Swine, But a Lucky Swine"; 8) 1939 - First Soldier of the Reich; 9) 1940 - "I Can Force Them to Obey Me"; 10) 1941 - "We Have Nothing to Fear from the Americans"; 11) 1942 - "The Russians Are Done For"; 12) 1942-1943 Stalingrad; 13) 1943 - Infernal Machines; 14) 1944 - "When the Oxcart Gets Stuck in the Mud"; 15) July 20, 1944 - Exercise Completed; 16) After July 20, 1944 - The Last Knights; 17) March 1945-May 1945 - "In the Best Interests of the Nation"; 18) Appendix - Interview with General Heusinger; 19) Glossary of German Military Terms; 20) Sources; 21) Bibliography and 22) Index.  In addition to the above sections, "Operation Valkyrie - The German General's Plot Against Hitler" includes the following four maps: 1) The Battle of France, 1940; 2) Operation Barbarossa, 1941-1942; 3) The Eastern Front After Stalingrad 1943-1945 and 4) D-Day and the Liberation of France, June 1944-1945.  In addition to an insightful narrative, this book includes approximately 23 vintage black and white photographs.  This book is 274 pages and is in very good condition.  The author is Pierre Galante with Eugene Silianoff along with French to English translation provided by Mark Howson and Cary Ryan.  Edition published in 1981.
