The Memoirs of Colonel John S. Mosby
John Singleton Mosby, the ‘Gray Ghost’, was one of the most effective military leaders of the American Civil War.
Since the close of the war, I have come to know Colonel Mosby personally, and somewhat intimately. . . .There were probably but few men in the South who could have commanded successfully a separate detachment, in the rear of an opposing army and so near the border of hostilities, as long as he did without losing his entire command.— Ulysses S. Grant
