The Northern German Defence Line 1916-18 (
Sicherungsstellung Nord)

 Sicherungsstellung Nord (Defence Line North) was build by the Imperial German Army in the years 1916-1918, to prevent an invasion by
 either landed English troops, or an attack by Denmark. 900 concrete and timber rooms and artillery platforms were build across the
 Southern Jutland. From the Lillebaelt in the east to the Island of Roemoe in the west this very strong and heavily defence line blocked the
 Northern German flank.

 How could it be possible for Germany to build a Defence Line in an area that is known to be Danish? In 1848 a rebellion started in two
 of the three the small Danish duchies Slesvig and Holsten. It was supported by Prussia. The Danish Army moved into the region, and
 won what is later known as the First  Danish-Prussian war 1848-1851. It ended without a lasting peace and both politivcal and military
 it was a stale mate. The peace treaty was dictated by the big powers, England, France and Russia.
Denmark it was considered a great victory.
                  The victorious Danish army
               returning to Copenhagen 1850.

 In 1864 Prussia provoked the Danish King, and he acted as Germany hoped, and the second Danish  Prussian War was a reality.
 The Prussians and Austrians invaded Denmark.  
 Denmark had a series of defeats.
For 3 month the Danish redoubts at Dybböl were heavily bombarded by modern German artillery.The
 Danish positions were attacked and occupied april the 18th 1864, and only a ceasefire saved the remaining Danish troops at the little
 island of Als.
 The ceasefire ran out June the 29th. where Als were attacked in a Prussian amphibious operation. After this, the war in fact was over.  

The Boarder before 1920, guarded by the Landsturm

 This peace treaty resulted in an Danish loss of the southern part of Jutland. 20 % of the territory, and overnight the Danish population in
 the area became German
subjects. The Area was considered German, the names of the cities were changed and the Danish flag
. German became the language in the schools. Also the young men were enlisted in the German Army.

                      In 1864 all the green areas became
                     German and the new boarder was drawn
                     at the top  of the light-green area.

                     After 1920 the boarder was moved south
                     to the midle of the light green area. 

 At the time the defence line was build, the area was Germany and the population Germans.
 After World War 1, a referendum was held in the area. The people in the three former Danish duchies were able to determine, where
 they wanted to
belong. The Northern third voted for Denmark and the boarder was moved south again to where it is to day.  

         The blown  heavy Battery
         at Gammelskov 2009 

 After a short documentation of the defence line, the Danish Army demolished most of it in 1921-1922. The government was afraid
 it later could be used ad the basic for a new German attack on Danish territory. The Defence could not be used by Denmark because
 it was directed to the north.  
 The Defence Line was forgotten by most people a covered by natural vegetation. Some places, the small bunkers were used as
 storages for potatoes.
 But the Danes that had seen the batteries, the boys who played around them remembered what they looked like and what was in them.
 In the mid 1970’s a Danish engineer, Mogens Scott Hansen, got interest in the defence line.
 He quitted his job, and used 15 years to
 listen to witnesses, draw and photograph the constructions and trace the forgotten and concealed constructions. Most of our knowledge
 about the defence line to day is due to his work. 
 The original drawings and other papers were destroyed at an English air raid on the German Naval Headquarters in 1945.
