This is a very important and terrific guidebook dedicated to the famous Hindenburg Line or, by it's actual German designation, "Siegfriedstellung". Field Marshal Hindenburg and his deputy, Ludendorff determined that Germany needed to go on the defensive as 1917 commenced and thus, was born a fortified defensive zone which German troops retreated to after laying to waste the previously occupied territory. This guidebook examines the genesis of the Hindenburg Line and the various battles required to extricate the German forces. It has terrific black and white photos, excellent maps for driving tours and examines the battle areas as they appear today. It is illuminating and fascinating history of battlefields rarely visited. Peter Oldham has attempted to bring this history to the "armchair historian" so it can be better appreciated and that the battlefield visitor can find villages, woods, bunkers, trenches and cemeteries with ease. I am an "armchair historian" of these Battleground Europe guidebooks and I particularly enjoy studying World War One battles. These books allow me to vicariously tour the battlefields that I cannot physically visit. I also recommend another guidebook for a neglected area of World War One History: the area of the village of St. Quentin. St. Quentin: Hindenburg Line For some time, I have been studying the Battle of Cambrai and have recently purchased guidebooks for that area. I think these volumes integrate well with the Hindenburg Line and St. Quentin to provide a more comprehensive view. Cambrai: Hindenburg Line (Battleground Europe. Hindenburg Line) Bourlon Wood: Hindenburg Line (Battleground Europe) and Flesquieres Hindenburg Line (Battleground Europe).
