I picked up this book because the author has always been kind of an obsessionist. Not in spite of his personal faults, but because he is a gifted storyteller and often presents interesting stories on topics that interest him. Unfortunately there are numerous factual errors so much as to be comical - such as describing General Lee saying "Oh, I'm sorry, he was one of my greatest friends.." which turned out to not be completely accurate.
Bad review
