"When compared to other Michigan regiments that fought in the Civil War, the Fifth Michigan stands out. It had the highest number of casualties of all Michigan infantry regiments in the war. Of all Union infantry regiments in the war, the Fifth Michigan ranked 4th in total number of casualties endured. A logical explanation for so many combat deaths and wounds is the fact that the Fighting Fifth played a key role in numerous charges against Confederate positions: twice at Williamsburg (Battle of Williamsburg), and at Fair Oaks (Battle of Seven Pines) the Wilderness (Battle of the Wilderness), Spotsylvania, North Anna, and Petersburg."
