I finished this book 10 minutes ago and found it to be not only an account of the author's odyssey to learn more about his grandfather's service in the First World War with Company D of the U.S. 1st Infantry Division, but also a poignant and thoughtful portrait (through excerpts from letters) of several members of Company D who distinguished themselves in combat from Cantigny to the Argonne.
This book also offers a sobering insight on America's role in a long ago war whose relevance is lost on most Americans today.
