An extremely well done look at Pickett’s Charge. The eBook includes a discussion of Gettysburg as well as how the Battle and the Famous Charge were used in the historical perspective afterwards. It includes a look at who was to blame (or not to blame) for what happened at Gettysburg as well as discussion of the Union Generals. It even looks at the question of Chamberlain. It is somewhat general, but it is a good place to start.
