This is an outstanding, well-written, well-researched book. McChristian takes the reader into the regular day-to-day life of an Army enlisted soldier between 1865-1891. He starts at the beginning with a soldier's recruitment and the enlistment process and how that worked, to their basic training, travel to their assigned regiments, typical duties and life in garrison, what they ate, how they were paid, and even how they got their clothes washed. He also covers things like promotion and awards, military justice, life in the field, duties of specialized positions like bandsman and buglers, and the separation process.
