Wilhelm Kaufmann describes in his comprehensive and detailed work the contribution and merit of the nearly 750,000 Union soldiers with various forms of German roots who participated in the American Civil War from 1861 to 1865. Organized according to the chronological course of the war, he explains the role that Germans played in the battles across the entire North American continent. Kaufmann supplements his explanations with extensive map material. This is a reprint of the original edition from 1911.
