独仏休戦協定
Molvange did not see significant action in the Battle of France in 1940, nor in the Lorraine Campaign of 1944. 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 and surrendered to the Germans following the Second Armistice at Compiègne of 22 June.
