This is not just another book about the Atlantic Wall during the Second World War. This book aims to give the reader an understanding of the part of the Atlantic Wall located in Denmark, specifically on the West Coast of the Jutland Peninsula. How did the Wall fit in with the overall German plans? How was it built? The book will also explore the different alternatives the Allies had for an invasion of Europe and if the Danish part of the Wall in any way affected the ranking of the alternatives. Denmark is also the place for one of the most extensive fortifications in Europe, the 38 cm battery of Hanstholm. This battery will be explored, as well as the general strategic thinking behind it and how it was supposed to have worked with its counterpart in Norway, battery Vara.
