The Fortifications of Copenhagen

The Outbreak of World War I and The Danish Semi-mobilisation.


  The outbreak of WWI forced Denmark to enlist 50.000 men to stay neutral. The 40.000 were designated to The New Fortress around Copenhagen. In the period 1914-15 Denmark had the biggest army ever.
It was not really a mobilization, but at force only meant to claim the neutrality. The mobilization order was given august 1st 1914. 

The fortresses was made almost ready for battle, and some of the last armaments were made. Some of these works was only meant
to be made in case of mobilization, but were made nevertheless. Miles of barbed wire was established along the waterline and around the caponieres at the southern defense line. Demolition of bridges and dams were prepared and known holes in the defense lines, necessary for roads, railroads and bridges, were closed. 

Numerous corps of volunteers reported in for duty in the defense line.  Paramilitary civilians were designated to operate the machine-guns. Volunteers who had trained in their spare time. Young engineer-students attended the complex searchlight and its generators.

The Artillery was attended by the 3. btn of the Fortress Artillery Regiment. The Regiment was founded in 1867 on the basis of some regiments, that were hasty founded in 1863 to attend the heavy artillery in Dannevirke, Dybbøl and  Fredericia.   
The military life in the southern defense life was not attractive. From 1914 there were stationed 1 sergeant with 10 infantrymen in every caponiere.  Here they slept, dined and lived - without the warm and dry rooms the fortresses in the north offered the soldiers.

Food and coffee was brought in mobile kitchens on the road along the defense line.
