Hobling (A23), Ligne Maginot
Hobling was approved for construction by CORF (Commission d'Organisation des Régions Fortifiées), the Maginot Line's design and construction agency, in 1931 and became operational by 1935, at a cost of 14 million francs. The contractor was Gianotti of Nice.
Block 1: infantry block with two GFM cloches,armed with a JM bell cloches (twinning machine guns).
Block 2: infantry/entry and casemate flanking north with two automatic rifle cloches (GFM) and one twin machine gun embrasure and one 47mm anti-tank gun.
Block 3: infantry block with one GFM cloche and one retractable twin machine gun turret.
Block 4: observation block with one observation cloche (VDP) and one automatic rifle embrasure.
Block 5: planned but not built equipped with an 81mm mortar turret, and an entry block at the end of a gallery of about 200 metres (660 ft) were not built.
In June 1940 the garrison comprised 115 men and 4 officers of the 164th Fortress Infantry Regiment (RIF). The commanding officer was Captain Boileau. The Casernement de Férange provided peacetime above-ground barracks and support services to Hobling and other positions in the area. The units were under the umbrella of the 3rd Army, Army Group 2.
Hobling played no significant role in either the Battle of France in 1940 or the Lorraine Campaign of 1944. Although there are signs of battle around. Hobling remained under Army control until after 1971.

Underground:
La Salle des Filtres - Gas filtration room.
Due to gas warfair being used in WW1, the French like all nations worried about gas attacks. So all their Overages were protected against gas attack. A large rubber seal was attached to all gas tight doors.
The next deffence was to over pressurise the Overage to above normal air pressure by means of large fans. Succing in air from outside, and punping it all around the overage. The air then escaped through small apitures as embrasures and gun positions. This had two effects, one to obviate the gas problem and also when a gun fired it helped to remove the foul gasses produced. The last defence against gas was to filter all air coming into the overage and by passing the fresh/or gas tainted air through a filter system. The filters in overages where enough for 12hours and would need constant changing when a gas attack happened over a long perriod. That meant a group of men going to each filter case and replacing the inner filters. A gas life of about 2 to 3 hours each filter.
The fitration system was manufactured by SNCF the railway company and all these filters seem to have dates of 1939 and 1940.
