Secret, Target XII/32,
RHUBARB OPERATIONS - APPENDIX XII,
CAP D'ANTIFER,
(Aircraft Reporting Station).
3. Position
i. The target is dispersed over three sites 13 miles N.N.E. of LE HAVRE and midway between the lighthouse on CAP D'ANTIFER and the coastal village of BRUNEVAL 1 & a quarter miles S.S.W.
iii. Altitude, 350 feet above sea level.
4. Description.
i. The most northerly site (this one in the above plan) pin point (F) close to the cliff edge 750 yds S. of the lighthouse, contains a Freya apparatus beside which is a small operational hut, and, a short distance further S., a Giant Wuerzburg standing on a circular concrete base. This site is surrounded on the landward side by a long trench, outside with a a belt of wire. There are also slit trenches behind the Giant.
iv. The entire area is heavily defended by light A.A. and a double belt of wire, as well as additional wire defence round individual parts of the target.
'AUERHAHN' was attacked on 11, 22, 23 and 30 May and 2 and 3 June 1944 in the deception plan for D-day. On the early morning D-Day. 617 Sqn (Dam Busters) used window (slivers of silver paper) to jam radar and balloons tethered to boats with radar reflectors to imitate a large ships. It made the radar screens look like a large invasion fleet was coming across. This was operation Taxable and it was very successful.

05 June 1944.
This was Operation Taxable and involved 16 617 Squadron aircraft flying a very precise series of timed runs at 200kts and smooth turns over the channel while dropping window on a strict timetable. All together this was designed to look like a large convoy slowly approaching the French coast on the German coastal radar screens. The operation was carried out off the Cap d'Antifer and German 15th army radar units reported a large naval force between Boulogne and Etretat, the whole area being placed on alert.

The road from le Poterie to Cap d'Antifer lighthouse. The pre war lighthouse was demolished just before its capture in 1944 and a new one built.
The original lighthouse showing as a target for Allied air forces.
The Lighthouse/Semaphore also had a Coastwatcher and Giant Würzburg radar sets.

Vf67 Tobruk.
Tobruks, I think this type is a Vf67. The entrance via a trench and into a crew/ammunition room and then up usually three steps to the gun room. This had a ring around the top where a machine gun could be swivelled 360°. A crew of one or two, depending on the importance of the position. This one covers the eastern flank along the top of the cliff.

I can find no information about this piece of concrete. So I have an idea.
Filled with water and barrels for
2cm AA guns could be put in to cool??. I have seen a barrel cooling sink on the island of Alderney. M.B. Elsaß, Fort Albert, Alderney.

Not at all sure what this was and nothing on the plan. But there are quite a few railway lines used just in the fence posts, so they must have been used either as defence posts/anti glider posts or there was a railway line laid to the other site around the woods of La Poterie Farm.

V229 Radar Socket
Würzburg Riese FUMG65. (‘Riese’ German for ‘Giant’)
Detection range up to 70 kilometres.
The initial homing in on an enemy aircraft is performed by another radar, as here a Freya radar. After detection by the Freya radar , the Würzburg Riese radar takes over and transmits all acquired data of the tracked object through an intermediate analogue computer device (Kommandogerät) to an anti-aircraft artillery unit.

I am not a Radar expert but I believe the closer the operator screen can be to the dish, the shorter the connections, the better the radar works. So on the Giant Würzberg the cabin sits right behind the dish and travels around with it.

This was the main entrance into the radar site from La Poterie. All traffic would pass through here as there was an anti-tank ditch, two widths of barbed wire and probably a minefield.

Vf58c Tobruk.
Armed with a machine gun and a rifle, maybe another man to help load the MG. He too would have a rifle and your job would be to cover the whole of the east side of the radar site with your machine gun. Also to be used as an AA weapon against low flying fighter/bombers. Of which, by 1943 were becoming a very regular sight here.
