Flak position that was laid out to protect the building of many heavy gun positions and radar sites in the Hague peninsular to the west of Cherbourg. Later completely removed and all that is left are the five concrete plinths.

So its October 2017 and I am in Normandy to visit my friend John and his wife in Fierville-les-Mines. I have some spare time and decide to have a 'mooch' around in my Rav 4 (now sadly moved on). Just checked, as of 2025 its still on the road. I had seen some mysterious concrete posts in the distance on many occasions and decided it was time to find them.

This site was armed, as early as February 1942, by a temporary anti-aircraft battery consisting of six 8.8cm Flak 18 guns. This battery, 4./344, belonged to the Schwere-Flak-Abteilung 344 (heavy anti-aircraft battery) under the command of Major Eugen Maier, who deployed his four batteries mainly in the western sector of Cherbourg and remained in position until November 1943 then they moving to Rouen. On the top of this windswept hill, six field gun emplacements were built, as well as about fifteen wooden barracks used as accommodations for the gun crews. A fire control post, located to the north west, is equipped with a Flak Kommandogerät 40 and to the south, a 60cm searchlight (Scheinwerfer) occupying a wooden platform mounted on concrete piles. The AA batterie was placed here to help defend the radar and radio-navigation sites in the area and for the protection of the two coastal batteries at Auderville. Currently, nothing remains of these wooden structures except for the five concrete piles that served as foundations.

60 cm Flakscheinwerfer (anti-aircraft searchlight) (Flak-Sw 36). The SW 36 anti-aircraft searchlight was developed in the late 1930s. It was a lightweight and portable device, easy to deploy. Its primary function was to search for and detect enemy aircraft at low and medium altitudes. The projector is powered by a generator. The 60 cm projector is equipped with a 60 cm diameter parabolic reflector lens. The focal length is 250 mm. As with heavier projectors, the high-density arc lamp is mounted inverted within the projector. The diffused light intensity is 135 million candela. Under favourable weather conditions, the light beam can be carried to a maximum altitude of 5200 m. The optimal operating altitude is 1500 m. However, with beam dispersion, target detection is possible up to a distance of 3500 meters. The power consumption is 90 amperes at 60 volts. Thanks to the handles implemented by the room manager seated behind the projector, the projector can be manually aligned on-site and in azimuth. The beam can be blocked by a shutter. Setting up the projector requires a team of five: 1. Room Chief, who issues the orders. 1. Soldier responsible for monitoring and locating the projector. They are responsible for maintenance and repair in case of a malfunction. They are subject to the room manager's instructions. 1. Soldier responsible for setting up the projector and aligning the beam with the target. 1. Soldier responsible for the generator. 1. truck driver. Manufactured by AEG, Bodenbach Zeiss & Jena 1941 to 1945 and 6376 were made.

Each pier had a slot in the top to place a wooden plank and then the rest of the wooden assembly would tie into the piers.

The concrete looks more stone than sand & cement?

Range finder. This was placed to the N/W of the batterie. There are no remains of the batterie. Flak Kommandogerät 40. Was of a stereoscopic design and had a four meter optical tube. It was designed to work with heavy FlaK 18s and Flak 40s. In order to operate effectively, the Kommandogerät 40 required at least a crew of five men. Inside were two telescopic lenses, operator lenses, and adjustable mirrors. By calculating the length of the tube and the angle at which the lenses were positioned, the crew could pinpoint where the target aircraft was. The optics used in the design were high quality like most made in Germany at the time. Furthermore, the Kommandogerät 40 was a crucial part of any FlaK defence and was met by praise from many a fire-control team. The machine itself could rotate a full 360 degrees and had an elevation range from 0 to 90 degrees. The total weight of the Kommandogerät 40 was around 915 kilograms and this did become a disadvantage because it made the machine near immobile. Another disadvantage was that it took a skilled crew to operate it. The Kommandogerät 40 was designed in the late 1930s to replace aging World War I era equipment in Germany's anti-aircraft divisions. In 1940, it was accepted for service. It was produced in the thousands and was used in a variety of settings where it was needed.

8.8cm Flak in a field position as the ones here would have been. A Flak Company would be fully self-contained, they would have had transport, generator, range finder, command and usually six guns. They could move, set up and, fight. Here they were around for some time, so instead of living in tents, they had several wooden huts built.
