One can’t read of that [Civil] War without playing the fascinating game of what-if . . . What if Jackson had lived through Chancellorsville? What if McClellan had listened to Phil Kearny (instead of to the Pinkerton detectives) during the Seven Days? What if Jeb Stuart had tended to business at Gettysburg?
