on 22.9.44 the OKM Seekriegsleitung anounces at the Lagebesprechung the start of the radiobroadcasts with the surrounded fortresses in France. One of the tasks was to pass important messages from familiy to the German soldiers in the fortesses (for instance Lorient, St-Nazaire and Dunkirk).

On 31-8-1944 the demolishing of the Dieppe and Fecamp harbours was declared finished. The harbour and facilities were out of order for a long time (according to the OKM). It seems that also the harbour of Le Treport had to be demolished but there was no contact with Le Treport.

The "back" of Cotentin was not as well protected as the bay where later the beaches would become D-Daybeaches. But still they do have nice bunkers, you have to do a long beachwalk but it will pay off. Especially in the summerevenings when the sun is low. Lots of small Tobruks but also nice type 676.

The area of Cherbourg has it share of bunkers in all kinds of use and some are special. This is a picture of a commandbunker type 608, this one has a non standard observationpost added. It was once covered by a steel plate (probably a 7P7 -10cm thick). It is located at MKB Brommy.

A rather onknown artillerypostion behind Juno Beach. It is not always big bunkers that housed divisional batteries. Most of them were just low profile simple bunkers for ammo and men. Later in the war many were upgraded by big bombproof bunkers.
