                   The Stevns Fort
                  
Royal Danish Navy
                                            


 The Strategic Position of Denmark 

 The strategic position of Denmark as  "The Cork in the Baltic" made it neccesary to protect The
 Danish territory, the airspace and the waters.
 To Protect the strait of the Øresund and to defend minefields at the expected landing beachhead at
 Fakse Bay, it was decided to buils a artillery fort at the southern end of Øresund.   

 The fort was build from 1952 to 1953 and in 1954 the barracks nearby were finished.
 Before the construction, there was a careful study of positions build by the Germans in Denmark
 during
WW2 and a British coastal battery at Dover. Dover, in particular, had an underground similar
 to
Stevns. 

 The Building and construction was made by the Danish Construction company Rasmussen &
 Schiøtz

 1.7 km. of tunnels were drilled and blown in the underground, 18 metres under the surface. The fort
 was situated at the end of
a cliff, and the drilling started in two tunnels from the beach. These tunnels
 are still known as
“foxholes”. The removed material from the tunnels was simply thrown into the see,
 and had soon disappeared. 

 The special underground in The Stevns peninsula (geological known as Bryozo-chalk) is very
 chock absorbing.  
 This special chalk is extremely good at absorbing chocks of both conventional shells and nuclear
 weapons on the
surface.  
 

 The Gneisenau guns

 The main armament of the fort was 4 pieces of 15 cm guns in two armoured turrets.
 The turrets were connected by the tunnel system.

 Originally the guns were placed as secondary armament on the WW2 German pocket battleship
 Gneisenau of the
Gneisenau/Scarnhorst class.

 1939

 

 
 
 At operation Cerberus in 1942,
The Gneisenau along with Scarnhorst and Printz Eugen, broke
 through the English Channel from
 Brest in France to German Harbours. In this operation, the
 Gneisenau was damaged by a mine. It was to be repaired in Kiel, but against all rules,  it was not
 emptied for ammunition before
docking.
 During this docking the ship was hit by an air attack, and a bomb exploded in the
280 mm front
 triple gun turret A.
 The explosion
destroyed the entire front of the ship and 112 men were killed.

Austrått Fortress in Norway

   The sad end of a proud  
   ship. The Gneisenau
   sunk outside Gotenhaven
   harbour as a blockship..

 
The Gneisenau were brought to Gotenhaven (Gdynia) in Poland for repair and new armament of 380
 mm guns.
 However this
never happened.
 In 1943 Hitler ordered (Führerbefehl) that all heavy ships, from light cruisers and onwards, should be
 demolished.
 He was not satisfied with their efforts. Because of this “Führerbefehl, the artillery were removed from
 the heavy
units and used as the armament on the Atlantic Wall. neisenau itself was sunk as a block-
 ship in the harbour of Gotenhaven (Gdynia) It was scrapped by the Poles after the war.
 The two turrets from the Stevns Fort were originally placed on the north part of the western Danish
 island Fanoe
as The Graadyb Battery. (Batteri Graadyb).
 In 1952 the turrets were moved from Fanoe to their current position on the Stevns Fort.

Turret No. 2
 

 
 In 1957 a 12.7 cm. gun, meant for shooting lightflare shells, were mounted. This gun was in the
 early
1960’s replaced with a 15 cm. gun. It had a range of 23 kilometres.
 In a period launchers for light rockets has been mounted on the outside of the turret.

 Where this gun comes from is unknown, but it is of German origin.

 Storing and mounting
 

 
 Beside the main artillery two batteries of double 40 mm. anti aircraft guns were placed in a
 southern and a northern  battery.
 It was possible to reach the southern battery from the tunnels, but not the Northern. It was either
 to difficult or to expencive to dig this tunnel.
 Each battery consisted of 3 pieces of guns with two barrels. Both batteries were demolished in
 late 1970’s.

  Langelands  Fort)

 Two 150 cm floodlights were mounted to light up naval targets for the artillery, but these were used
 only
in the first half of the forts active period.
 
 
 The two permanent 40 mm Anti Aircraft
 Batteries had a 60  cm. floodlight each
.

Originally the fort had 8 mobile 40 mm anti aircraft guns, but this number was later increased to 18
 
pieces in 1997.

The Entrance

 The only entrance to the tunnel system was though the bunker in the northern end.
 At the entrance bunker they were three flanking positions for defence of the entrance. In the
 start the famous Danish Madsen machine gun was used for the defence, and later the German
 machinegun M/62, used
as a standard for the Danish Army.
 Inside there are an elevator and a staircase to the tunnels and an artillery command post for the
 first piece of artillery.

 At  the end of the stairs there are two doors.
 A normal and one through the ABC-cleaning facility. In this facility it was possible to clean soldiers,
 who at the surface had been hit by nuclear, biological or chemical wweapons. Yhis had to happen
 before they entered the fort.

The tunnels and the rooms

 The main tunnel was curved. In the middle the two artillery sections were divided by heavy
 armoured doors. This was made to be able to stop an attack from one end to another. Also it
 prevented explosions to spread.           

    The armoured doors were eighter taken from
    abendoned German bunker in Jutland or made
    on the Navys shipyard "Holmen" in Copen
    hagen.
    They are most lightly german.

 At all the crossings of the tunnels, bulges were made in the walls to prevent explosions to spread
 from  the side tunnels to the main tunnel. 

 From the main tunnel there
 was access to the radar
 antennas. hidden in the fort.
 At the top these tubes were
 closed with 5 cm. armour

 
  In case of crash or weakening of
  walls and ceiling, there were
  stores of timber in the tunnels.

 To supply the fort with power and water there was a lot og heavy machinery.
 This was placed in two large ingeneer centrals in each end af the fort.

 To each gun there was an ammunition store with an elevator to to the gun..

 If the Fort should become active i wartime, several hundreds og men had to live and fight here.
 For weeks - maybe for months. To talk about years is not reasonable.
 With  no kitchen facilities, they would have to live of the armys standard rations.
 In peacetime they were eating in the barracks nearby.

 Other facilities in the tunnels were also rather primitive.

 Post for fresh water
 in the main tunnel.
 Mens room in the main
 tunnel.
 No women - no doors
   
 It was a naval fort and
 things were done the
 naval way. Room for
 36 artillery crew men
 and 10 petty officers.
 
 The hospital had a
 number of beds in the
 main tunnel.

 
   The Original Operations Rooms.   




 
 in the southern end of the tunnes, the operations
 rooms and the artillery central were placed.
 It was moved to the hospital rooms in the
 northern part when the fort was modernized in
 1982-84.

    The Artillery Calculator

 
 The Artillery Control Central was a part of the original operations rooms.
 Here the targets were plotted, and firing data calculated.
 It was before the computer as we know it today, and we are talking about large calculations.
 Speed og the target, direction and speed of the wind, air pressure and the flying time of the
 grenade on a distance of 23 km. The target could easily move 500 meters.
 
 The data were put into the calculator on the little black wheels on top af the machine.


 The Operations Rooms

 The operations room was the last part of the fort in use.
 Earlier it was situated in an other part of the tunnels, but after a modernising in 1982-84, it was
 moved to the rooms of the former hospital.  (described below)
 The Royal danish Naval Radio Service and Oeresund Naval Region had its command central
 here.

 The Hospital

 
In the beginning the fort had its own hospital with 2 surgical theatres.
  It had an initial department with 18 beds and a hospital department with 36 beds.
 
It also had rooms for 6 patients declared dead, but still under observation.
 
X-ray was available and there were stores of medicine and bandages. There was no store of blood,
 but the
blood type of all crew was known.
 The hospital was able to treat heavily burned victims, in case of  an attack with phosphor or
 napalm.

 There even was a chapel in two minor rooms, where killed members of the crew could be stored
 until
fighting was ended and they could be brought to the family or buried on the fort area.
  In case of major damages, the hospital had 80 beds in the northern part of the tunnels.
 The
hospital facilities were after a modernizing of the fort 1982-84 replaced by the Operations
 Rooms.

 The barracks
 
Not more than the neccesary number of crew were supposed to be in the fort in peacetime.
 The barracks nearby were used.

 Possible weaknesses of the Fort

 There was not sufficient toilets for 2-300 men. They could be forced to stay there for weeks or
 months..........(nuclear attack)
 This Could cause serious deceases among the crew.

 There was only on pipe for fire hoses. It was placed at the entrance bunker. Hardly sufficient at a
 major fire....
(The southern artillery store is far from the entrance)
 
 There were not sufficient kitchen facilities. This could be a problem if the fort was under fire for a
 longer period.
 Along with the toilet problems, it might inflict the morale.
