Ouvrage Bambesch was a minor fortification within the extensive Maginot Line, a defense line constructed by France during the 1930s. The primary aim of the line was to impede an invasion by Nazi Germany. In May 1940, the German army invaded France via the Ardennes, a region previously deemed impassable by the French. The Germans bypassed the Maginot Line and rendering it largely useless.

Constructed in 1932, Ouvrage Bambesch is situated in the Bois de Bambesch and includes three infantry blocks. These blocks are interconnected by extensive subterranean passages that also accommodate facilities for barracks, utilities, and ammunition storage. On 20 June 1940, Ouvrage Bambesch came under assault from German forces. The initial attack targeted Block 2, compelling the defenders to retreat into the subterranean corridors. Despite support from the neighboring Kerfent fortification, the situation was hopeless and the garrison surrendered after two hours of bombardment.
