Gi12 'Hamburg', Gironde Nord
I am having a difficult time here working out what was here and where they were. There seem to be several contradictory reports and also the site was bombed almost to oblivion and I think that has not helped. After D-Day and the brake out from the Cherbourg peninsular, the Americans went due west into Brittany and also headed east for Paris. The British were working their way up the channel coast towards Belgium and Holland. So that left Brest, Lorient, La Pallice and the Gironde still in German hands. Brest was eventually taken at great cost to the Americans and so they decided to bottle up the remaining Festungs on the west coast. The Americans brought in fresh troops directly from America and used them to bed down and get used to warfare by holding the Germans in their fortifications. As time went on, the Free French, mostly volunteers and ex resistance fighters. Decided they wanted the Gironde opened up and so with the Americans reluctant (my words) help. Battle commenced.
In all, according to the Air Force Historical Studies Office, "1,161 heavy bombers destroyed 22 defensive installations consisting of AA and arty positions and strong points covering the Gironde estuary"..
On a darker note, the bombing of Royan would be the Eighth Air Force's only use a new weapon in an attempt to kill Germans in their bunkers: napalm . Known as a Class-C Fire Bomb, each napalm bomb contained 108 Gallons of the petroleum substance, and they were only used in a few missions. A B-17 only carried 4 of them ...
As a result of the conventional and napalm bombing of the city of Royan, the city was totally destroyed, with one report citing that only nine houses remained standing . Among the destructive figures is cited that 1,700 French civilians were killed. Mission 25: April 15, 1945. Target: Royan, Fr. A 9-hour mission against troop concentration in Nazi pocket near Bordeaux. Formed over Laon, France. Flew over Paris. Bombed visually from 15,000 feet. No flak in our formation. Ship #807 with 6 - 600# gasoline-jelly P-51 tanks (leaked all over hell [in airplane]. Free French Navy shelling town while we bombed.
[Note: "Mission 951. 1,348 unescorted bombers [B-17 and B-24] are dispatched to visually attack strong points on the French Atlantic coast; the first two forces [My father's was the first one.] below make the sole operational employment of napalm bombs by Eighth AF against German ground installations (pillboxes, gun pits, tank trenches, and heavy gun emplacements); the results are negligible and HQ recommends its discontinuance against this type of target:
1. 492 of 529 B-17s hit four strong points and flak batteries in the Royan area."] From Axis History Forum.

Open emplacement
Open emplacement for the gun inside casemate 13. That casemate has been removed. The guns could be used inside the casemates or wheeled out and placed on their open emplacements and an almost 360° radius of action, but not the concrete protection though. After the casemates were built, it looks like the ringstands were covered over by sand that was used to be pushed up onto the sides of the casemate as extra protection and also camouflage. 13 had a flak position on its roof, there seem as though there was no flack assigned to the batterie but I am sure they had at least a 2cm / 3.7cm Flak of some kind.

This is the open ringstand for the field gun like the last one. It seems this is where the field guns were originally mounted and then when the casemate was built (this one in 1943) that the ringstands were covered over with sand and not used.

R680 for a 7.5cm Pak 40
This R680 shows an interesting rear wall holding back the sand and a flanking wall to the seaward side. The Pak 40 & the 8.8cm Pak 43's were found to be uneconomical to use in the fast moving Russian front and Panzerfousts were becoming plentiful, cheaper, quicker and easier to be used. So a casemate was designed for the spare Pak 40 (R680) and an R677 for a Pak 43. This gun would have covered a long way down the beach and any landing craft or tank would have been systematically shot away by it.
