Investigations sur le "Mur de l'Atlantique" - Atlantikwall

The port of Grand-Camp from an airphoto, post card.

The port was defended by this tank turret from a French Renault FT tank of WW1 vintage. Over 3,000 Renault FT tanks were manufactured by France, most of them in 1918. The French had many of these tanks still either in service or in reserve and the German army, removed the turrets and fitted field guns to make the tanks into mobile armoured artillery. So that left the turrets and they were re used in the Atlantikwall as static defence. They could have a 8mm Riebel machine gun,vor a 37 mm Puteaux SA 18 gun.

Puteaux SA 18 gun.

U type Tobruk for a French FT turret like the one used here at Maisy. You can see the second crew man handing ammunition to the gunner.

The Bigot map of the defences of Grandcamp, dated around April 1944.

Bigot, if you were in the know about D-Day, you were a 'Bigot', the code name for those in the know. If you were not a Bigot you would not have seen anything at all as it was such a well kept secret.

36 - the anti-submarine net.

Anti-submarine net, it would have had floatation buoys to hold the net up.
The German Navy probably had a team of sailors who's job it was to see that the net is kept across the entrance an all times, unless a fishing boat or a German naval vessel needed to enter or leave. The ports along the coast were used by many small naval units as communication, supplies, etc.
