The fortifications of the Atlantic Wall are among the best-known images of World War II. We are all familiar with photographs of long-range coastal guns, protruding from reinforced concrete casemates. They stand above beaches studded with barbed wire and anti-tank obstacles, dwarfing the sentries standing guard next to them. Yet despite the enormous efforts expended on creating these formidable-looking defences, in June 1944 they failed to withstand the Allied armada launched at them from across the Channel. Did Nazi Germany’s strategy for the defence of occupied western Europe stand any chance of success?
Improvising defence
The Atlantic Wall was certainly a remarkable feat of engineering. In trying to protect 2,000 miles of coastline, from Norway to the Pyrenees, the Germans used 17 million cubic metres of concrete and 1.2 million tons of steel to build a series of batteries, bunkers, observation posts, and other structures. More than 200,000 workers – a mixture of volunteers, conscripts, and slave labourers drawn from occupied countries – were employed on the project over a four-year period.
Nazi propaganda trumpeted the Wall’s impregnability, with menacing shots of steel-helmeted soldiers manning gun emplacements in the German press and newsreels. Yet the project had serious flaws. The Wall was the product of improvisation rather than the outcome of coherent forward-planning. Although some work began as early as 1940, following the fall of France, construction did not begin in earnest until the spring of 1942. It was at this point that Hitler’s thinking began to take a more defensive turn, as he started to focus on the growing likelihood of an Anglo-American attempt to break his hold on western Europe. British raids on the French ports of St Nazaire and Dieppe (in March and August 1942 respectively) reinforced his conviction that a more serious attack would come.
