The St Mihiel salient had been formed in 1914 as the Germans drove towards Paris at the beginning of World War I (1914-1918). The French had attempted to recapture it in 1915 without success and in 1916 the Germans used the area as a base to attack Verdun. The bitter battle for Verdun had cost hundreds of thousands of German and French casualties. After the Germans called off their attack of the salient, the war shifted north, leaving the salient protruding ominously into the Allied lines. Despite holding the salient since 1914, after the losses of early 1918, Ludendorff reluctantly decided to abandon the area and retire to a heavily fortified line at the base of the salient. The evacuation was ordered to begin on September 8, 1918. This was to be the scene for the newly formed American Army's first major offensive of the war. This highly illustrated and detailed account will highlight every aspect of this important campaign.
