In September 1863, President Lincoln considered Major General William S. Rosecrans (1819–1898) the most able general on the Union side, but only one month later “Old Rosy” was removed from his command and then quickly forgotten. With The Edge of Glory, William M. Lamers returns this imposing, colorful figure to his rightful place in history.

Lamers examines many of Rosecrans’s wartime experiences, including his role as commander of the Army of the Cumberland. Yet the demise of Rosecrans’s distinguished military career, Lamers illustrates, was not a result of his humiliating defeat at Chickamauga but of his difficult, uncompromising personality and the scorn he aroused in many of his superiors, including General Ulysses S. Grant and Edwin Stanton, Lincoln’s secretary of war. Although Rosecrans fell short of greatness as a military commander, Lamers deftly shows that he did indeed reach “the edge of glory.”
