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 his career 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.

A study in character and values, courage, nobility, honesty, and selflessness, here is an unforgettable story about a man who embodies the best in our nation—and in us all.
