Mike Tolhurst's father fought in the battle for Normandy. Perhaps that is why the narrative portion of this book reads with such emotion, not just military matter-of-factness. This book would succeed, I believe, simply as an account of this part of the war, even without the "travel guide" aspects. Eyewitness accounts and quotes from German as well as Allied soldiers bring what was happening to life.
I had already decided to go to Normandy when I purchased this book. But it was invaluable in helping me decide which places to see, since I knew my time would be limited. Each chapter consists of a narrative of part of the battle, then an accompanying suggested tour which touches on cities and places mentioned in that chapter. I ended up not following the plans exactly, but still basing my choices of places to go on the authors' narratives.
I found Normandy to be beautiful and welcoming, and would recommend that every American, Canadian and UK native visit these sites if you can, most especially if a relative fought in the war. If you do you'll need some guidance as to what to see and where it is, and this book will help a great deal.
