Built by Nazi Germany between 1936 and 1938, over 500,000 workers were involved in its construction. This book gives a detailed historical background to the Siegfried Line, and a guide to what is left to see of it today. The line was not designed to thwart a full-scale offensive, but rather to delay any attack sufficiently to allow the German reserves to mobilise. In the 'phoney war' (1939-40) it was effective enough to prevent the French from launching a pre-emptive strike when German forces were heavily engaged in Poland. Certain sections of the defences saw some of the fiercest fighting of the Second World War. Much has since been dismantled, but some still remains today. This, the first English-language guide to the Siegfried Line, is fully illustrated and will appeal to anyone interested in the rise and fall of Hitler and Nazism, or in the Second World War in general.
