The Fortifications of Copenhagen
 

The flanking foxholes of the  Tune Position

                                                     
  
There were built a total of 29 individual foxholes, 3 single caves with observation platforms and 7 double caves. Each cave was equipped with a 40 cm. carbon floodlight  and two recoil guns.
 
                  
                 The Skel foxholethe only intact doublecave.
 
             
The Vendals foxhole, North of Karlsstrup.             Single foxhole.
 
The purpose of the caves was to provide flanking fire on the barbed wire closures, so hostile infantry was shot at from the side while they forced the barbed wire entanglements.
Completely in the spirit of experiences and the huge huge losses this tactic had caused at the trenches on the battlefields of Europe.

The double caves were equipped with 4 recoil guns and 2 floodlights. They were angled, and had two flanking tasks.
The Caves were gradually replaced by so-called galleries, presumably because the large hole for the floodlight was too great a risk for caves.

The caves consisted of 12-15 cm reinforced concrete in the walls and 20-25 cm in the ceiling. Rocks were placed under 0.5-1 m earth for early detonation.
