is close at hand on the east. Manning The manning of the ouvrage in 1940 comprised 513 men and 14 officers of the 169th Fortress Infantry Regiment and the 151st Position Artillery Regiment. The units were under the umbrella of the 42nd Fortress Corps of the 3rd Army, Army Group 2. The commandant de l'ouvrage in 1940 was Commandant Charnal. The Casernement de Cattenom provided peacetime above-ground barracks and support services to Kobenbusch and other ouvrages in the area. History See Fortified Sector of Thionville for a broader discussion of the events of 1940 in the Thionville sector of the Maginot Line. Kobenbusch did not see significant action in the Battle of France in 1940, nor in the Lorraine Campaign of 1944. Kobenbusch provided suppressing fire against German infiltrators on the surface of Oberheid. About the same time, a party of Germans infiltrated the area of Kobenbusch Block 5. The Germans largely bypassed the area, advancing along the valley of the Meuse and Saar rivers, threatening the rear of the Thionville sector. An order to fortress troops by sector commander Colonel Jean-Patrice O'Sullivan to prepare for withdrawal on 17 June was reversed by O'Sullivan. The garrison therefore remained in place. Following negotiations, the positions on the left bank of the Moselle finally surrendered to the Germans on 30 June 1940. Present status While the entry and combat blocks remain visible, the underground galleries, barracks, ammunition magazine and utility areas, which lie at an average depth of below the surface, have been flooded by the cooling water lake of the nearby Cattenom Nuclear Power Plant. The site has been owned by EDF since the construction of the power plant in 1981. It is maintained by the Association Ligne Maginot du Secteur Fortifié du Bois de Cattenom, which manages Bois Karre, the Abri du Bois de Cattenom, Ouvrage Sentzich and Ouvrage Galgenberg. A pedestrian path through the surface installation is under development, and the Abri du Bois de Cattenom may be visited at times.
