Detroit's Alpheus Starkey Williams never tired in service to his city or his country. A veteran of the Mexican-American War, he was a preeminent military figure in Michigan before the Civil War. He was key to the Lost Order, the Battle of Gettysburg, the March to the Sea and the Carolinas Campaign. His generalship at Antietam made possible the Emancipation Proclamation, and Meade and Sherman relied on his unshakable leadership. A steady hand in wartime and in peacetime, Williams was a Yale graduate, lawyer, judge, editor, municipal official, militia officer, diplomat and congressman who stood on principle over party. With vivid battlefield accounts based on extensive primary research, award-winning author Jack Dempsey's masterful biography tells the amazing story of this unsung hero.
