The Air Raids That Shook Britain During the Great War. Shown in a Chronological Series of Official Ordnance Survey Maps. With Expert Commentary by Ian Castle

This is a massive book - oversize and with over 500 pages. Most of the book is Ordnance Survey or equivalent maps of various parts of the U.K. showing on them the route of either the Zeppelins or the Gotha heavy bombers which sustained the German air raids throughout the war. The first half of the book is "Airship and Aeroplane Raids from 25 December 1914 to 27-28 November 1916". The second half is "Airship and Aeroplane Raids from 16-17 March 1917 to 19-20 May 1918". Each raid has a map allocated to it, with the route of the bombers inscribed, plus a narrative. This book rightly belongs in the "Official Histories" Main Category.
