Origin and history
The H.K.B. 4./706 "Stahl" battery, installed in May 1942 at Alderville-la-Roche (northwest of the Hague Point), was initially equipped with six French guns in open encumbrances, served by regelbau 134 or Vf7a ammunition bunkers. The wooden barracks, now disappeared, completed the device. This strategic site was part of the Stützpunkt 351, a German coastal defence network during the occupation.
Starting in the summer of 1943, the battery was reconfigured with the construction of a fire direction post (Leitstand) Regelbau 636, five troop shelters (types 621 and 622) and uncompleted Regelbau 679 casemates. A Seetakt FuMO2 radar and a telemeter, protected by a camouflaged Asbest coating (a mixture of straw, asbestos and cement), equipped the PDT. Flak's parts reinforced air defence. Renamed H.K.B. 1./1262 in December 1943, the battery underwent a massive American bombardment on 29 June 1944, prior to the Allied take of the ring tip on 1 July 1944.
The site, consisting of 24 elements (casemates, bunkers, shelters), is now fully protected for its archaeological and historical remains, including associated cadastral plots. The remaining works, such as the TDP or encumbrances, bear witness to German camouflage and military engineering techniques. The battery illustrates the intensity of the fighting for the control of the Cotentin, key area of the Normandy Landing. The remains, owned by the state or private, have been classified since December 2024 for their heritage value related to the Second World War.
