"Rebel" is the first complete biography of the Confederacy's best-known partisan commander, John Singleton Mosby, the "Gray Ghost." A practicing attorney in Virginia and at first a reluctant soldier, in 1861 Mosby took to soldiering with a vengeance, becoming one of the Confederate army's highest-profile officers, known especially for his cavalry battalion's continued and effective harassment of Union armies in northern Virginia. Although hunted after the war and regarded, in fact, as the last Confederate officer to surrender, he later became anathema to former Confederates for his willingness to forget the past and his desire to heal the nation's wounds. Appointed U.S. consul in Hong Kong, he soon initiated an anticorruption campaign that ruined careers in the Far East and Washington. Then, following a stint as a railroad attorney in California, he surfaced again as a government investigator sent by President Theodore Roosevelt to tear down cattlemen's fences on public lands in the West. Ironically, he ended his career as an attorney in the U.S. Department of Justice.
