Tobruks, more formally
designated as Ringstande,
were t h e most w i d e l y use field
fortification in t h e

Atlantikwall.

They were small, simple
structures w i t h a characteristic
r o u n d o p e n i n g for a machine
g u n or other w e a p o n . Since
they had an o p e n roof and were
built t o t h e lower B1 standards,
they were not designated
" p e r m a n e n t " fortifications.
This example was part of t h e
IJmuiden fortification zone.

Note:

Coastal artillery units in Norway were designated in an alternate format than elsewhere on the Atlantikwall. The format for batteries in Norway was,
for example, HKB 6/908 where HKB or MKB identifies army or navy battery, prefix (6) identifies battery number, suffix (908) identifies parent regiment.
The standard format for battalions elsewhere was, for example, 1./HKAA.980 where numeral prefix (1.) identifies the battery, a Roman numeral prefix (II.)
identifies a battalion, and a numerical suffix (980) identifies parent regiment.

By far the m o s t spectacular c o a s t a l artillery in N o r w a y w e r e the three d o z e n
heavy naval g u n s , usually surplus w a r s h i p w e a p o n s , assigned to critical defensive

The most powerful guns emplaced in Norway were the massive

Each battery consisted of four gun positions, located about
2 5 0 m apart. Battery Trondenes I, also known as Batterie Theo,

Trondenes, which had a m a x i m u m range of 5 6 k m (35 miles). The

Engeloy to cover the Vestfjorden on the southern approach to

single mounting with a turret of

light 4 5 m m armor steel. The guns were fitted to an S384 complex,

Narvik. The four gun positions were located 8 5 - 1 0 5 m above sea

which consisted of a deep concrete well with a high gun pedestal,

level. Construction of the battery started in 1942, but the battery

along with a series of tunnels leading back into reinforced concrete

was not entirely complete at war's end. A reserve ammunition

bunker and an emergency headquarters for the regional Seeko

battery in France, Batterie Lindemann near Calais, an overhead
