In 1862, a prominent Republican visited President Lincoln and called General Ulysses S. Grant an incompetent drunk who created unnecessary political problems. Lincoln, frustrated with all his generals but this one, famously replied: "I can't spare this man; he fights." Indeed, Lincoln had gone through a series of unheroic generals before settling on Grant to lead the Union's Army of the Potomac. Grant's success at marshaling the industrial might of the North eventually pounded the South into submission. This memoir, finished as its author was dying of throat cancer in 1885, is widely admired for its clear and straightforward prose. The volume was an enormously popular hit upon publication (by Mark Twain, no less), and today Personal Memoirs of U.S. Grant ranks among the finest pieces of military autobiography ever written.
