This special covers the railway batteries in the area. They were part of the long distance guns (Fernkampf Batterien) which covered the Channel. The capacity of the guns made it also possible to fire on British soil. In the organisation they were placed under the command of the army (das Heer). Two main units were responsible for Calais, both used several pre-fixed firing locations for their guns. These locations were interconnected with railway tracks. There was even a track that could bring a gun from one unit to the other. The positions were defended with infantry weapons, mostly placed in thin concrete. Once the gun was placed in the position, it could rotate 360 degrees by using a turntable. Unfortunately there are no remains of these constructions.
