The Rohrbach sector was built somewhat later than its neighbors to the east and west, and in company with positions on the extreme western end of the Maginot Line, became one of the "New Fronts."

[9] The Casernement de Bining provided peacetime above-ground barracks and support services to Welschhof and other positions in the area.

During the morning of 22 June the Germans assembled a battery of light artillery to attack Welschhof, which was no longer covered by the positions to the west.

The Germans moved two 150 mm guns from the entrance to Simserhof and began to attack Block 1 at Welschhof and Casemate Ouest de Singling.

[13] American forces reached the area at the very end of 1944, with the U.S. 397th Infantry Regiment taking up positions around Welschhof, with no resistance from the ouvrage, which was not occupied by the Germans.

[14] By 1951 work was proceeding on renovation of many of the northeastern ouvrages, including Welschhof, with the aim of restoring their combat capability to block a potential advance by the Warsaw Pact.
