“Once an Eagle is 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 reissued 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.
