In 1861, when the Civil War began, Ulysses S. Grant was an ill-paid, somewhat-drunken, 38-year-old clerk in the township of Galena, Illinois. Four years later, when he received the surrender of the Confederate forces under Robert E. Lee at the historic courthouse of Appomattox, Grant had established himself as one of the great military commanders of all time. How such a transformation, as extraordinary as any in the annals of generalship, came about is examined in this volume. The author portrays Grant as one of the great military commanders and strategists of history. This book persuasively sets out the grounds upon which this conviction is based.
