Coastal Gun Battery Oldenburg

The Germans already started construction of the gun battery Oldenburg in July 1940. This should keep the English channel free of Allied ships during the forthcoming German invasion of the UK. Later the role of the battery became more defensive and the guns were a part of the Germans' Atlantic wall. The guns had been used one month before, in support of the attack on France. The two guns had been captured by the Germans during the First World War and subsequently modernized in the Krupp factory. The caliper was changed to German standard 240 mm. and with a shell weight of 150 kg., the range of the guns was 28 km. In autumn 1940 the germans began casting two large pillboxes to the guns, more crew bunkers, another gun bunker, and also a garage bunker and a fire commando bunker.
