No argument there. My only knock about the Stonewall book is that it is probably a little too gushing - in terms of heaping maybe too much praise on Stonewall. He went too easy on him during the Seven Days, for example. Other than that, I think very highly about Robertson's ACW knowledge and his ability to convey that knowledge to others.
What I was trying to point out was that when, on Maxwell's website, it was announced that the movie would get made and that Stonewall would be a major character in it, Robertson went a bit overboard in defending his favorits subject, almost to the point of deifying the guy.
