Description Montdidier-Noyon, 9 - 13 June 1918. Ludendorff followed up his stalled Aisne offensive with a small-scale drive in the Montdidier-Noyon sector on 9 June 1918. Twenty-one German division attacked the French on a twenty-three mile front extending from Montdidier to the Oise River. The French anticipated the assault and contained it after a nine-mile penetration by the Germans, counterattacking strongly. The fighting was over by 12 June, and the enemy had little to show for the heavy losses incurred. No large American units were in the immediate vicinity of this action, although the 1st Division at Cantigny was subjected to artillery fire and diversionary raids.
