As there was a lot of heavy fighting around here after the fall of Brest, the peninsular was the next objective. This bunker may have been heavily used.

This is one of the two entrances and you can see the entrance sides are angled to allow stretchers access.

Why this battery has attached casemates to their M270 casemates I have no idea, I suppose it gives a sort of 120deg in the front and about 130deg behind gun cover.

08 October 2006

C346 'M.K.B. Kerbonn'

Concrete slapped on the finished casemate and then loose stones added to create a camouflage effect.

7.5cm casemate attached at the rear of the main casemate. It has its own little cap in the roof and a built up glace's in front of where the gun would have sat.

Turm 1main gun room with ammunition supply slots through the rear wall and cable inlets from the fire control post and the small square opening giving access to the spent ammunition space. When the gun fired the shell case is ejected from the gun and placed in a hole in the floor and after the battle the cases would have been collected and re-used.

08 October 2006

Ammunition slot where the case would have been passed through from the case room behind.

StP/Wn C346 'M.K.B. Kerbonn'

Another odd detail here is that the floor is made of ships plating. All casemates that I have seen the gun is tied down into the concrete floor. here the gun was attached to a piece of ships deck plate and the casemate built around it.

C346 'M.K.B. Kerbonn'

The view across the cliff top at the M162a fire control post (PDT) and to its right should be a search light and I think the original fire control post and on the other side is the French battery position.

When the occupation army arrived in Brittany, the navy saw the advantage of using Brest as a U-boat dock. So then the navy needed to protect its assets. Before the casemates were built, this concrete and rock structure was built to hold a range finder unit.

This is what it looked like..

C346 'M.K.B. Kerbonn'

The design of an M162a bunker has a Tobruk set into the left hand side. Due to the positioning of this bunker this one has been strengthened and extended in height.

08 October 2006

C346 'M.K.B. Kerbonn'

Two views of the top of this Tobruk. The damage done may have been due to the removal of the machine gun ring as well as some battle damage?
