Query: About as bad as a Civil War book can get

That a book purporting to be a detailed, comprehensive tactical study offers only one map pretty well reflects the carelessness, and lack of respect for the reader, with which this book apparently was produced. I've written thirteen books on the Civil War and Indian Wars myself, and I understand the importance of good maps. The prose also is sloppy, and the author repeats the same absurd premise - that a few more men in the ranks of one regiment might have changed the course of Gettysburg, and thus of the Civil War - so many times that one feels tempted to toss the book across the room. An absolute disgrace to the field of military history.
