I wish there was a way to give 3-1/2 stars because that's what I felt this book earned for a rating. It was simple enough to use for a staff ride handbook which covered all the basic points of the battle in an easy to read format but a bit more detail than what you would expect from perhaps a civilian version auto tour, as this is geared towards current and future military leadership. The vignettes are helpful as each story was pertinent to the section and did provide needed context to what was just discussed.
However, I did find the questions at the end of each chapter quite lame. I would expect better questions for a survey 100-level military history course at a civilian institution than that, so coming from the U.S. Army's Combat Studies Institute, I expected some deeper probing questions that would be more appropriate for looking more thoroughly into the subject matter.
The book flows pretty well but is pretty basic, which is why it gets the three-star treatment. Nothing spectacular but nothing bad here. If you used this book to do a battlefield tour, you would definitely find your way around and learn something, especially from the Union perspective. It's a little bit light on some Confederate perspectives but does try to approach the two armies with some degree of balance whenever possible.
