Audinghem Pas de Calais
With the fall of France in June 1940, the English Channel coast of the Pas de Calais was in German hands. Attention turned to the control of the Channel and preparations for Operation Sea Lion, the invasion of England.

In July 1940, the Germans began building permanent coastal batteries between Calais and Boulogne. They also moved rail guns into the area.  

The Batteries would be able to dominate the entrance and exit to the narrow English Channel, as well as being able to shell the south east coast of England. The first shells landing on Dover town the second week in August 1940. The British endeavoured to retaliate by building their own batteries to provide counter battery fires. Artillery duels across the English Channel ensued.

 One of the coastal batteries constructed was near the village of Audinghem 20 km (12 miles) north of Boulogne near the Cape de Gris. Construction of the Battery commenced in August 1940. The battery would consist of four Coastal Defence version of the 38cm SK C/34 Naval Gun. The guns were mounted in an armoured turret, which were later housed in reinforced concrete casemates.

The 38cm SK C/4 was developed for the Bismark Class Battleships. The coastal defence version had a modified chamber for additional propellant in order to achieve longer ranges, The gun fired a 495 kg (1,091 pounds) to a range of 55km (35 miles). it had a rate of fire of 2.5 rounds per minute.

The guns armoured turret, a C/39 mount, had an upper compartment which housed the guns and loading equipment. A lower chamber contained ammunition hoists with motors for the elevating  and traversing gear.

In 1941, Hitler deemed that additional protection was required and the construction of reinforced casemates commenced. Whilst offering more protection, it reduced the field of fire from 6400 mills to 2150 mills.

Raversyde - Battery Saltzweddel Neu

The Battery Saltzweddel Neu built during World War Two has been preserved providing an insight of the defences that made up the Atlantic Wall.

On 10th May 1940 Germany launched their invasion of Belgium sweeping through the country forcing the Belgian, French and British Armies to withdraw. Eighteen days later Belgium surrendered and four and half years of occupation commenced.

To consolidate their gains, the Kreigsmarine began the construction of a coastal battery in Summer 1941 to protect the port of Ostend. The first armaments installed were captured Belgian 120mm guns which were re-designated 12 cm K 370 (b). The guns fired a 22kg (48 pound) shell up to a range of 17.5 km (11 miles).
 

The gun emplacements were open platforms.

 On the 23rd March 1942 Hitler issued Fuhrer Order 40 to create the Atlantic Wall, a series of coastal defences stretching from Norway to the Spanish Coast to prevent an allied invasion of Europe.


 The Battery Saltzweddel Neu was incorporated into the Atlantic Wall, its defences strengthened and it was re-named Battery Tirpitz. As part of the Atlantic Wall, guns were to be housed in casemates for protection.

In 1943, four R671 Casemates were constructed housing 10.5 cm SK C/32U guns which were also used on U-Boats. They fired a 15kg (33 pound) shell 15 kilometres (9 miles).

To protect the flanks two R612 Casemate were constructed to house 7.5 cm PAK 40, an anti-tank gun with a range of 1,800 metres. The gun could be removed from the casemate on to an external platform to give a wider field of fire.

 The Battery was controlled from an Observation / Command Bunker. It was operated by the Marine Artillerie Abteilung 204. Its establishment consisted of a Battery Commander, 20 NCO's and 100 Other Ranks. Gun detachments were 8 men strong.

Anti-aircraft guns were added during 1944. Their intent was to disrup Allied aircraft en route to, and returning from, air raids on Germany.

Following the Allied Invasion of Normandy in June 1944, it was recognised that the Pas de Calais was unlikely to be the scene of any landings .  Attention was turned inland  and PAK 36 37mm Anti-Tank guns with a range of 5,500 metres (6,000 yards) were added for protection.
