A very readable academic look at the history and role of the over 2300 Union chaplains in the Civil War. Using a wide variety of original records, the book covered pay, duties, uniform, how they got along with different denominations, their views on slavery and how they made the lives of the soldiers better. Not all of them were unselfish, but most were dedicated to being there for the men to comfort them when they were sick in spirit or body. Aside from their ministerial duties, they wrote letters for those in the hospital, held educational classes when at camp, dug rifle pits and wells, foraged for food, helped the surgeons by wrapping wounds during battle, taught former slaves to read and write and even a few picked up arms to defend their units. Overall it was a fascinating look at a rarely discussed aspect of the Civil War.
