Whatever one learns of the Great War always seems to contridict what has been learnt before. What this book supplies is the missing link. The battlefeilds as they were. From the pictures one is able to get an impression of the persepectives involved. One important aspect is the removal of the mythology of the waste land of mud so prevelant. The views show the British front from the North down to the Somme, as they were and changed. It would take a month to get even half of the knowledge contained in these pictures out. It really is a must have for anyone with an intrest in this time.
