It is an astute study of the mind and character of a good general and a good man. And it is a brilliant inside view of the life of a career officer in peace and war.\" — New York Times “Simply the best work of fiction on leadership in print.” —General Martin E. Dempsey, 18th Chairman of the Joint Chiefs of Staff Required reading for West Point and Marine Corps cadets, Once An Eagle is the story of one special man, a soldier named Sam Damon, and his adversary over a lifetime, fellow officer Courtney Massengale. Damon is a professional who puts duty, honor, and the men he commands above self-interest. Massengale, however, brilliantly advances by making the right connections behind the lines and in Washington's corridors of power. Beginning in the French countryside during the Great War, the conflict between these adversaries solidifies in the isolated garrison life marking peacetime, intensifies in the deadly Pacific jungles of World War II, and reaches its treacherous conclusion in the last major battleground of the Cold War—Vietnam. Now with a new foreword by acclaimed historian Carlo D'Este, here is an unforgettable story of a man who embodies the best in our nation—and in us all.","forthcoming":false,"isbn13":"9780062221629","publication_date":"20130312","publisher":"HarperCollins","slug":"once-an-eagle","subtitle":"A Novel","title":"Once an Eagle"},"discovery":{"categories":{"all":[{"bisac_code":"HIS027110","confidence_band":"medium","label":"U.S. Military History","score":0.7971,"source":"bisac_hint_model"},{"bisac_code":"HIS027190","confidence_band":"medium","label":"Afghan War (2001-)","score":0.7878,"source":"bisac_hint_model"},{"bisac_code":"HIS027280","confidence_band":"medium","label":"Guerrilla Warfare","score":0.7846,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"HIS027110","confidence_band":"medium","label":"U.S. Military History","score":0.7971,"source":"bisac_hint_model"},{"bisac_code":"HIS027190","confidence_band":"medium","label":"Afghan War (2001-)","score":0.7878,"source":"bisac_hint_model"},{"bisac_code":"HIS027280","confidence_band":"medium","label":"Guerrilla Warfare","score":0.7846,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"FIC002000","confidence_band":"high","label":"Action & Adventure","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC004000","confidence_band":"high","label":"The Classics","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC014040","confidence_band":"high","label":"World War I Historical Fiction","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC014050","confidence_band":"high","label":"World War II & Holocaust","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC019000","confidence_band":"high","label":"Literary Fiction","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC025000","confidence_band":"high","label":"Psychological Fiction","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC032000","confidence_band":"high","label":"War Fiction","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC037000","confidence_band":"high","label":"Political Fiction","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"U.S. Military History","score":0.7971,"slug":"u-s-military-history"},{"label":"Afghan War (2001-)","score":0.7878,"slug":"afghan-war-2001"},{"label":"Guerrilla Warfare","score":0.7846,"slug":"guerrilla-warfare"}],"reader_fit":["Good for readers who enjoy U.S. Military History","Good for readers who enjoy U.S. Military History and Afghan War (2001-).","Strong fit for readers who prefer grounded, real-world context."],"related_lists":[{"intro":"","slug":"shelf-his027190-afghan-war-2001","title":"Afghan War (2001) Books","url":"https://bookfrontier.com/lists/shelf-his027190-afghan-war-2001"}],"series":null,"similar_books":[{"authors":["Thomas E.
