NAZI propaganda trumpeted Festug Europa--Fortress Europa. This was the Atlantic Wall that the NAZIs bragged could necer be breached. The German focus in 1941 was on Operation Barbarossa, the invasion of the Soviet Union. The Whermacht was shifted east. Despite failing to achieve victory in the Battle of Britain, the Luftwaffe was also shifted east, reloeving pressure on hard-pressed Britain. At first during 1941-42 the NAZIs concentrated on protecting the harbors. German artillery, anti-aircraft guns, and armor were positioned beginning in 1942 along the French coast. German armored divisions are transferred to France. Only in late 1943, however, with defeats in Russia and North Africa and the increasing build up of Allied forces in Europe did Hitler give real priority to the Atlantic defenses. Hitler's Atlantic Wall is perhaps the most massive fortified position in history. more extensive even than France's Maginot Line. It was a formidable obstacle that Allied planners had to confront. Construction was ordered by Hitler in Führer Directive No. 405. The French rail system plyed an important role in both the consruction of the Atlantic Wall and in plans to defend it against invasion.

Festug Europa

NAZI propaganda trumpeted Festug Europa--Fortress Europa. This was the Atlantic Wall that the NAZIs bragged could necer be breached. The German focus in 1941 was on Operation Barbarossa, the invasion of the Soviet Union. The Whermacht was shifted east. Despite failing to achieve victory in the Battle of Britain, the Luftwaffe was also shifted east, reloeving pressure on hard-pressed Britain.

Harbor Defenses

At first during 1941-42 the NAZIs concentrated on protecting the harbors. Armies require massive amounts of supplies. Moving in the supplies needed required a deep-water port. Thus the ports were afforded the greatest priority. Many were already guarded with pre-War French fortifications. German artillery, anti-aircraft guns, and armor were positioned beginning in 1942 along the French coast. German armored divisions are transferred to France.

German Forces

The German forces many the Atlantic Wall were divided into four army groups of uneven strength. The 15th Army guarded the Lowlandsand the Pas de Calais. This was the most strongly defended area, especially the Pas de Calais as it offered the shortest Channel crossing and the most direct route into Germany. Allied deception efforts (Operation Fortitude) succeed in convincing the Germans what they had already suspected that the invasion would come here. The 7th army was the next strogest force. It guarded the coast from the Seine/Caen south to the Louarve River. As this included Normandy, it would prove to be the German units the Allied invasion force would confront on the beaches. The 18th Army covered the Louarve to the Pyranees. The 19th Army Guarded the Frence southern or Mediterranean coast. The German High Command had not seriously considered an invasion through 1943 and the increasingly critical situation on the Eastern Front caused them to redeploy forces in France. The High Command, however, knew that the Allies would strike in 1944, although they were unsure where and when. Hitler issued Führer Directive 51 in which he he announced that German forces in France would have to be reinforced (November 1943). The demands of the Eastern Front and the Allied invasion of Italy (September 1943), however, limited the forces which could be deployed. As work on coastal defenses had not had a high oriority, work would have to be rushed to prepare for the invasion. The Germans by June 1944 had deployed 56 Divisions in the West. The strength of these divisions, however, varied greatkly The strongest units were the Waffen S.S. These units were armored divisions equipped with the newest and best equipment. The Waffen SS included Paratroop Divisions and Six Panzer Divisions. The Germans no longer had the capability of making paratroop drops, but the paratroop units were highly trained and motivated. The German tanks were supperior to the American tanks, although the Americans tanks far exceeded the number of German tanks. The Wafen S.S. also were manned by men highly committed to the NAZI cause. One of the Waffen SS units was the 21st Hitler Youth Division. Many were below strength, manned by men who had been battered in the Eastrn Front. Some of thge German units were manned with foreign soldiers from Eastern Europe. (The Germans were afraid to use soldiers recruited in Western Europe, they were deployed in the east.) The Eastern Europeans constituted about 10 percent of the German forces, a not inconsiderable component. Some of these men were committed Fascists. Others had been drafted from from the slave labor camps and had joined only to escape from the dreadful conditions in the camp. Many of these men would surrender at the first available opportunity.

Preparations for Invasion

Only in late 1943, however, with defeats in Russia and North Africa and the increasing build up of Allied forces in Europe did Hitler give real priority to the Atlantic defenses. Hitler's Atlantic Wall is perhaps the most massive fortified position in history. more extensive even than France's Maginot Line. It was a formidable obstacle that Allied planners had to confront.

Construction

The Atlantic Wall was largest construction project of World War II. The Germans poured 17.3 million cubic yards of concrete, strengthened with 1.5 million tons of steel. Steel was a critical war material. The use of such a large quantity mean that steel was not available for other purposes. Much of the construction was done by French wokers conscripted from local towns and villages. The concrete went into massive bunkers of up tp 3.5 feet thick which could with stand direct hits. There were also many smaller bunkers and pillboxes of varying size. Construction was ordered by Hitler in Führer Directive No. 405. It was made up of massive trench system, similar to that of World War I. German newsreels in 1943 show Albert Speer inspecting Atlantic Wall building sites. Building supplies were unloaded as the construction of heavy-gun emplacements is continued.

Organization Todt

Fritz Todt was a friend of Hitler and an early party member. As a result from a small construction firm with 36 workers, the company became one of the largest companies in Germany. The company got the contract to build the Autobahns (1936). The OT also built the WEst Wall and was responsible for virtually all important military cinstruction projects during the War. The first major OT military project was the West Wall. It was thus to Organization Todt that Hitler turned to build the Atlantic Wall. It was not until completing the construction of defensive installations on the Channel Islands that work on the atlantic Wall could begin in ernest (late 1943).

French Rail System

The French rail system was important for building and once built moving the troops sand supplies needed to man the Ataltic Wall. The French rail system would also be needed to move the reinforcements and supplies needed to repel the invasion once the Allies struck. The problem for the Germans was that the Allies were destroying the Luftwaffe and by 1944 there was no longer a protctive roof over either the AStlantic Wall or the French rail system which sustained it.

Artillery

German artillery emplacements include guns ranging from 150-406 mm. The giant cannons, including a railroad gun of the Dora class were mounted in concrete and steel turrets. Atlantic Wall strong-points were built and protected with massive quantities of reinforced concrete. Some of the larger gun positions were armed with accurate 66, 75, 88, 115, and 155 mm guns. The larger pieces were naval guns capable of engaing battleships were installed in reinforced concrete bunkers or other strong points (Widerstandsnester). The larger emplacements proved impervious to aerial bombardment.

Rommel

Hitler appointed Field Marshal Erwin Rommel to oversee the defensive preparations on the Atlantic wall. Rommel was appointed inspector of coastal defenses and subsequently commander of Army Group B which guarded the French Channel coast. As army group commander, Rommel officially reported to the overall commander in chief West, the aging Gerd von Rundstedt. German newsreals in 1944 show Field Marshal Erwin Rommel inspecting the Wall. He had in fact been apauled by what he saw when Hitler assigned him the task of improvong the defenses and set upon a massive building and mine laying program. [Ambrose]

Defenses

The Wall was replete with with machine-gun nests and pillboxes for the infantry. The beaches were worked with barbed wire, mines, hedgehogs, Belgian gates, log ramps, and wooden posts. There were 0.5 million beach obstacles. Rommel was especially committed to mining the beaches. By the time the landings occurred, the Germans had laid 4.0-6.5 million mines (accounts vary) and were actively laying more to achieve Rommel's goal of 11 million mines. [Ambrose, pp. 109-111.] The Germans staged realistic combat exercises to test the defenses. These beach defenses were designed slow down the landing ships so shorte batteries could more easily engage them. Rommel's asparagus inland was to prevent glider landings.

Personnel

The Atlantic wall was primarily manned by immobile German Ost (East) Battalion troops. The Ost Battalion was made up of large numbers of captured Russian and Polish troops that had agreed to fight with the Germans because they either hated the Communists or wanted out of the concentration camps. Many were ready to surrender to the Americans or British at the first opportunity. Officers and non-coms were Germans. [Ambrose, p. 35.] The NAZIs generally did not equip non-German units with mobile armour.

Air Power

The fixed locations were also necessary because the Allies achievered air superiority.

Naval Artillery

The fixed positions allowed American war ships to engage them. When it looked like the landings at Omaha might fail, destryers moved in close to the baech to engage the shore batteries. [Ambrose, p. 386.]
