Betrayal At Gettysburg (1998) By Edward Aronoff
 
The author postulates what might have happened if Lee's generals did what he asked them to do, taking the track that if they had done so, the Confederates would have won the battle and Longstreet would have been arrested for treason and brought to a public trial.
