Of the several magazine-style part-works that appeared after the Great War and before the Second Word War, 'Twenty Years After - The Battlefields of 1914-1918 Then & Now' stands out as exceptional in its scope, and groundbreaking in its concept of placing original wartime photographic images alongside those taken in the late 1930s. Those images from the 1930s show a very different battlefield to that seen today, with many of the scars of war still evident, including some showing ­- amazingly, in today's politically correct world - piles of ordnance dug up by the local French population, that was available for purchase at the side of the road! Alongside the atmospheric images is an extensive text, describing many operations and locations on all Fronts, but mainly France & Flanders. With its thousands of superb photographs, this is a fine reference work. 'Twenty Years After - The Battlefields of 1914-1918 Then & Now' is not a publishing curiosity but a fascinating piece of Great War history that is still of much value today.
