Query: I want my $18.95 back

Amazon needs to update its rating system to include minus stars for books like this. How this stinker ever got published is a mystery to me. Walker cobbles his narrative together from a handful of secondary sources (Bruce Catton, D. S. Freeman, Gregory Urwin), has apparently never heard of the "Official Records" or regimental histories or "Gettysburg Magazine", spends 11 pages in a confused and and mostly wrong retelling of his "subject", and sets up this chapter with 125 pages of an irrelevant (and often wrong) summary of Lee's command of the Army of Northern Virginia. He knows just about nothing of the Civil War and detracts, rather than adds to the literature of the conflict. As a retired Army officer and professional historian I symbolically throw my hands skywards in dispair.
