StP Gatteville area defence
StP152 is surrounded by four Wn defences.
The batterie started out as a six Geschützstellung (Open ringstands) for 15.5cm K.420 (f) (captured French) guns and were gradually being replaced by four casemates, to house the K.420's with pedestal mounts.

Ref Map: GSGS 4250/6E1/391275. Chart Map F.1014.
Height above sea level: 12 meters.
Six 155mm guns. Range 25000 yards. Weight of shell 95lbs. Rate of fire 2 r.p.m.
Guns in open circular concrete emplacements, 75 - 85 yards apart.
Construction of four casemates of the "prefabricated " type was begun in February 1944, and
was nearly completed in earl;y April 1944, at which time there were no signs of construction
of additional casemates. The casemates measure 32 feet by 48 feet, and are sighted radially
in pairs. It is possibly that numbers 1 and 2 guns will continue to fire from their present
emplacements after the four casemates are completed and occupied.
Observation:
Possible OP's 389278 (no concrete), and at 396275.
Secondery Armament: One, possibly two light AA guns.
Dummy: At 3957274.

29 May 1944 just before D-Day this photo was taken of the batterie, showing all the defences and the straight lines were buried telephone cables. They lead out to the lighthouse and to all the defence positions in the area. One would have also gone to the batteries HQ.
The
battery was placed here to cover on one side Cherbourg Harbour and on the other Barfleur and down to about Quineville. A range of 25000yards, about 22000meters..

How it looked with six of these open emplacements. Originally four guns were placed here, around 1943 in filed positions and two went to Batterie 'Brommy', Couplets StP272. When all the ringstands (Geschützstellung) were finished the guns from Couplets came down to complete the batterie. By early 1944 four Casemates were constructed and finished by May 1944. I think only three of the guns were removed from their open emplacements and then fitted into the casemates.

Captured by the Americans around the 26th/27th June.
The Germans when they left just before the Americans came in. Sabotaged all the guns, as they could not be removed. All the ammunition was left and was not removed until 1947. Although the guns were fitted into the casemates, their gun chassis were left in case they were needed again. I expect that there was not enough time to dismantle the guns and also no prime mover lorries to tow them away.
This gun looks as though it was sabotaged. The recuperating oil may have been drained out so the gun would not work.

Leitstand. The viewing slit where a rangefinder would have been placed in the centre of the room, underneath another room where all the workings out would be done. The computing room. A target is usually one item, but with four guns in spread out positions. Number 1 gun would be calculated (Usually the far left Turm 1).Then the calculations for the other guns. Computers were used for these calculations, not nice electronic ones but very mechanical, clockwork types. The distance from FCP to target would be worked out, then the distance calculated from each gun and the angles needed to be fired at.
Observation.
Calculations: -
FCP to Target - distance.
T1 to Target - distance.
T2 to Target - distance.
