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.

Pas De Calais - Krupp K5 Rail Gun

Krupp K5 280mm Rail Gun
Following the fall of France in June 1940, the Germans began deploying rail guns to the Pas de Calias to support Operation Sea Lion, the invasion of Britain.  In addition permanent coastal batteries would be built between Calais and Boulogne to control the English Channel. 
English Channel Gun Batteries
 The Germans established five main locations for 280mm Krupp K5 rail guns in the Pas De Calais area.  The batteries consisted of four two gun batteries and a single one gun battery.
Normally only one gun would be firing, the other undergoing maintenance.

The guns were housed in Dombunkers, reinforced concrete shelters, or in railway tunnels to protect the guns when they were not firing.  The guns would be brought from their shelter, prepared for firing, the mission carried out, then return to their protected shelters.

 Twenty five Krupp K5 Rail Guns were produced, but only two remain today. One of the remaining guns is located at the Atlantic Wall Museum,  Audinghem, 20 km (12 miles) north of Boulogne.

 The development of the K5 began in 1934 with the first testing following in 1936. Eight guns were available for the invasion of France in 1940.

The K5 had a range 64 km (40 miles) firing a 255 kg (562 pounds) high explosive shell.
 

The time taken to prepare for firing and the low rate of fire (15 rounds per hour)  limited the guns to land based targets.  Dover and the South Coast were targeted.

The guns had a limited traverse consequently to set the bearing required, the gun needed to be rotated on a railway turntable or moved along a curved track.

The guns were moved to and from the firing position by a WR360C14 diesel shunter locomotive.

A small gauge railway track was laid from the ammunition storage to the gun in order to move the 255 kg (562 pounds) high explosive shell and cartridges. The shell and cartridges would be lifted by the gun's hoist onto a small ammunition trolley at the rear of the gun.

Two Krupp K5s were sent to Italy to target the Allied bridgehead at Anzio. The guns were nicknamed Leopold and Robert by the German Gunners, to the Allied soldiers under their distinctive fire, they were termed Anzio Annie and Anzio Express. The two guns were abandoned when the Allied forces broke out of the Anzio Beachhead.  



Leopold has been restored and  located at the Atlantic Wall Museum, Audinghem in the Pas de Calais.
