BATTLE OF VERDUN

During the Great War, Verdun was the pivot of France's eastern fortress line. It was defended by General Sarrail's forces against the advancing Germans in August 1914, and the victory of the Marne in September relieved the pressure on the fortress, although the Germans had gained and secured a foothold on the Meuse at St Mihiel.
