In 1943, 18-year-old Robert Ellis joined the elite U.S. Army Ski Troops of the 10th Mountain Division. This division has been called the most elite and publicized American military unit in World War II. While a member of the unit Ellis maintained a detailed battle diary and conducted extensive wartime correspondence.

Upon their arrival in Italy, the U.S. Army Ski Troops played a major role in the defeat of the Germans in Italy. They also faced some of the bloodiest combat of the war; the 10th Mountain Division suffered the heaviest casualties relative to time-in-combat of any U.S. division in the Italian campaign. While the author details the exceptional service of the unit, he also explores the brutal reality of infantry service and reveals how the battles were falsely represented by the media.
