I found this book extremely readable and very entertaining. Not something you can say about a lot of historical tomes.
The author gives a compelling account of the actual battle. So much so that the smell of the horses, the blood and gore and all the other noxious smells that are part and parcel of a battlefield seem to pervade the readers nostrils.
However the book is not just about the battle itself but also about the participants particularly the English King, scheming churchmen and murderous Dukes. The knightly heroes, cowards, surgeons and spies. The book has them all.
The author has made it possible for history to be enjoyed by a wider audience, rather than the academic. History has always been interesting. Books written like this one will make many more readers aware of that fact.
