The Fortifications of Copenhagen

The Caponieres of the Western Enceinte

 The revolutionary aspect of "the Sommerfeldt Front" or "The Danish Front" was that the severe fire of the enemy would only occur when he began
 to cross the channel and thus was weakest and most vulnerable. The channel was in the middle 3.5 meters deep.
 Throughout the 14 kilometres of the Enceinte caponierer there was situated every 600 meters in the water-edge on the eastern side of the
Enceinte. Each Caponieres cocering the back of the next by flanking fire.
 There were both single and double caponieres.
 Some blind spots were covered by small caponieres build into the rampage. These were first build in 1914 in order to cover a blind angle around
 the outside of the big caponieres .

                                                        Flanking the fire

 There were both single caponieren shooting in only one direction  and double caponieres that would shoot in both directions. The double
caponiere mirrored the single.
 The single caponiere was equipped with a rapid-firing 75 mm.kanon, 2 pcs. of 8 mm.  mittrailleuses and 2 pcs. of  8 mm. machineguns.
 The  Double caponiere had dual armament and twice the number of personnel.

 In a firing test from a caponiere in 1902, 95% of the 600 targets set, were hit within 3 minutes.
