Germany’s Atlantic Wall was the most ambitious military fortification program of World War II. Following its conquest of Western Europe, Germany had to defend some 5, 000km of Atlantic coastline from the Spanish border to the Arctic Circle. The United States’ entry into the war and the inevitability of an Anglo-American landing in Western Europe resulted in the fortification of this coastline along its entire length. Focusing on the northern Atlantic Wall in the Low Countries and Scandinavia, this title addresses the special defensive features and unique aspects of fortification in these countries, such as the early focus on fortifying Norway, due to early British commando raids; the greater use of turreted naval guns; and the establishment of first-line Flak defences in the Low Countries to counter the Allied strategic bombing campaign.
