The Atlantikwall (English: Atlantic wall) was an extensive system of coastal fortifications built by the GermanThird Reich in 1942 until 1944 during World War II along the western coast of Europe to defend against an anticipated Allied invasion of the continent from Great Britain.[1] On March 23, 1942 Führer Directive Number 40 called for the official creation of the Atlantic Wall. After the St. Nazaire Raid, on April 13, 1942 Hitler ordered naval and submarine bases to be heavily defended. Fortifications remained concentrated around ports until late in 1943 when defences were increased in other areas[2].
Organisation Todt, which had designed the Siegfried Line (Westwall) along the Franco-German border, was the chief engineering group responsible for the design and construction of the wall's major fortifications. Thousands of forced laborers were impressed to construct these permanent fortifications along the Dutch, Belgian and French coasts facing the English Channel.
Early in 1944, Field MarshalErwin Rommel was assigned to improve the defenses of the Wall. Rommel believed the existing coastal fortifications were entirely inadequate, and he immediately began strengthening them. Under his direction, a string of reinforced concretepillboxes were built along the beaches, or sometimes slightly inland, to house machine guns, antitank guns, and light artillery. Minefields and antitank obstacles were planted on the beaches themselves, and underwater obstacles and mines were planted in the waters just off shore. The intent was to destroy the Allied landing craft before they could even unload.
By the time of the invasion, the Germans had laid almost six million mines in northern France. More gun emplacements and minefields extended inland, along the roads leading out from the beaches. In likely landing spots for gliders and parachutists, the Germans emplaced slanted poles with sharpened tops, which the troops called Rommelspargel ("Rommel's asparagus"), and low-lying river and estuarine areas were permanently flooded as well.
Rommel firmly believed that the invasion would have to be stopped at the beach itself, or the situation would otherwise inevitably lead to the defeat of Germany.
The defensive wall was never completed; consisting primarily of batteries, bunkers, and minefields, which during 1942-1944 stretched from the French-Spanish border into Norway (Festung Norwegen). A number of the bunkers are still present, for example near Scheveningen, Den Haag, Katwijk and in Normandy. In Oostende, Belgium well-preserved part of the defenses can be visited. It consists of the emplacements of the "Saltzwedel neu battery" and the "Stützpunkt Bensberg", consisting of several men’s quarters and the necessary facilities. These constructions were used by a unit of military engineers (Pionierstab) who were in charge of the construction of bunkers.
The Channel Islandswere heavily fortified, particularly the island of Alderney which is the closest to France. Hitler had decreed that 10% of the steel and concrete used in the Atlantic Wall go to the Channel Islands, because of the propaganda value of controlling British territory.citation needed Despite the mooting of Operation Constellationet al, the Allies bypassed the islands for this reason and did not try to liberate them when they liberated Normandy. The islands' German garrisons did not surrender until 9 May1945 - one day after the rest of the German armed forces. The German garrison on Alderney did not surrender until 16 May.
Walcheren Island was considered to be the "strongest concentration of defences the Nazis had ever constructed."[3]
Many major ports and positions were made part of the Atlantic wall and received heavy fortifications, Hitler ordered them all to fight to the end[4] and some of them remained in German hands till the unconditional surrender of Axis Forces on May 8, 1945. Several of the port fortresses were resupplied by submarine after being surrounded by Allied forces. The defenders of these positions included Slavic soldiers and SS troops.[5].
Port wrecked by demolitions. 300 men on the fortified island of Cezembre held out till September 2, 1944. The island controlled the approaches to the port
