Query: Good but repetative

As many other reviewers have pointed out, the book is extremely authoritative on it's subject matter, and "shatters" a lot of old misunderstandings about the battle. However, it does have a serious flaw in that the authors definitely needed stronger editing. The writing is clear but they repeat the same points many times, and spend several paragraphs explaining something that was obvious after a sentence or two.
