Re305 M.K.B. 'Von Holtzendorf'

The large deep water port of Brest was able to receive battle ships like the Tirpitz. Also a U-boat pen was constructed inside the harbour. That meant that the whole area around the entrance to the Rade de Brest had to be defended. After the attack on the lock gate at St Nazaire the defence was again increased.

Plan

Admiral Henning von Holtzendorf (1853-1919). He served as commander of the High Seas Fleet from 1909 until 1913, retired. Recalled in September 1915, Holtzendorf was placed at the head of the naval General Staff. He was a great believer in U-boats.

Allied intelligence report

SK/Schartenstand plan. Large casemates built on the style of an M272 but with extra rooms at the rear.

15cm S.K. C/28's secondary ships armament

The Navy built their batteries either using standard type bunkers or making their own styles (SK [Sonder Konstruction] Special construction). The guns here were 15cm S.K. C/28's the sort of gun used as secondary armament on battle ships.

Re305 M.K.B. 'Von Holtzendorf''

The battery has four SK casemates (Sonderkonstruktion [none standard design]) set into a bank of earth (the original French battery position) for extra protection with an M150 fire control post in front (not built). Many Tobruk's circle the site giving machine gun protection. Four R622 twin group bunkers, M151 quarters bunker & an M145 ammunition bunker and about three search lights. There was also two batteries of AA guns, 3 at 'Arnika' in Fl243b emplacements & 'Erika' 5 guns in field positions all using ex French 7.5cm AA guns.

M151 quarters for 1Off. 3 NCO's and 24 men.

Appearing last year are two naval guns for some reason just plonked onto two concrete foundations??

The two ships guns.

Re305 M.K.B. 'Von Holtzendorf''

Up to 1942 a battery of artillery were in open emplacements with 164.7mm French guns but due to the allied heavy bombing Hitler ordered all artillery was to be places under concrete. So large casemates were constructed. The Navy, Marine Kusten Artillery batteries were to shoot on targets out to sea and were usually placed as close to the cliff's/beach as possible, whilst army (Heers) H.K.A. batteries were to fire on the beaches & surrounding country side and were located more inland.

This is the first casemate in the batterie..

The second has a ramp up to the front, this may have been built when the bunker was constructed or later when the French Navy owned the site.

I spy a little hole.

Re305 M.K.B. 'Von Holtzendorf''

I managed to poke the camera through at this vast casement interior. A vast space for the 15cm S.K.C/28 gun. The entrance on the right is for the shells to enter from the shell store behind.

Re305 M.K.B. 'Von Holtzendorf''

To the rear a flight of stairs leading into a sort of crew area of the casemate and the a shell and a case stores either side, with the gun room at the front. A passage came in from the right.

Re305 M.K.B. 'Von Holtzendorf''

Not sure of the reason for a ramp leading to the embrasure, it may have been a French construction post war.

A close up of the design to deflect incoming shrapnel. The brackets could be to hold the camouflage nets or a French post war fittings??

I believe this is an R622 twin group bunker set out in front of the gun line but behind the fire control bunker and may have held the crew of the FCB.

Tobruk local defence.

Machine gun scarf ring that fitted into the ring on the Tobruk..

Re305 M.K.B. 'Von Holtzendorf''

Periscope fitting. Periscopes were not a standard fitting in an R622 but here we have the Kriegsmarine and they have very different rules. I have not looked at where the forward fire control post was, thats for another trip. There was a plan to build an M150 but this had not been started.

Re305 M.K.B. 'Von Holtzendorf''

You can see how hard it is to get very close..

Re305 M.K.B. 'Von Holtzendorf''

Behind the gun line at Turm 2 is a French post war building and toilet block, as you can see now falling down. In the undergrowth it looks as though there is a Tobruk which may be attached to an R622 twin group bunker. Between the Tobruk & the French building is a semi sunk German concrete barrack room.
