The British writer Alan Clark, author of "Barbarossa: The Russian-German Conflict 1941–45", refers to Sajer's book in his "Diaries" as a book "to which AC Clark often turned". The book was considered by the U.S. Army Command and General Staff College to be an accurate "roman à clef" and has remained on its recommended reading list for World War II, along with other historical novels. It is also on the recommended reading list of the Commandant of the United States Marines Corps.
