This book covers the 107th Ohio Volunteer Infantry, a heavily ethnic German unit from Northeastern Ohio (Cleveland, Akron, Canton). Serving with the 11th Corps, they served from Gettysburg to Olustee to Camden (Potters Raid). It details the dislike of Germans during the time period and how they became scapegoats for the failures of leadership on all levels. Beyond that it covers the 107th's "banishment" to the Southern fringes of the war wear the climate provide just as much of a hazard as enemy fire.
Downside to this book is the obsessively heavy use of quotations in the first part of the book. For me, it hurts the flow of reading as I naturally pause (and change tone in my head) when I see then. They become more tolerable in later chapters.
