The German coastal defences created from 1940 extended south from the Norwegian North Cape to the border between France and Spain. The nature of the fortifications changed as the coastline changed along this great boundary. There was also variation caused by the German view of the threats they faced. The main construction, which has come to be referred to as the Atlantic Wall, runs from Spain along the French coast and up through Belgium to Holland, more than 1500 miles of coast. It was at its strongest along the section of coast from Brittany, along the coast of Normandy to the Belgian border. It can be argued that the Channel Islands formed part of the defences as a flak and coastal battery position off the French coast. Millions of tons of steel and concrete were used and the task was never finished and never as strong as the myth presented by those responsible for building it. Very little has been written in the English language about the Atlantic Wall and this book addresses that deficiency. The Germans poured huge amounts of resource into the construction and the Todt Organization made use of slave labour in addition to the many skilled military engineers and architects. Deciding on the scope of an account is difficult for any author. In this case, the author has concentrated mainly on the bunker system directly at the coast and provided much detail, including a good selection of photographs and a number of excellent sketches and engineering drawings.
