Third Battle of the Aisne, German Blücher-Yorck Offensive.
Operation Blücher-Yorck was General Erich Ludendorf's third major operation of the German Spring Offensive. The Germans launched seventeen Stormtrooper divisions for the first attack which began at 0100 hours on 27 May 1918 advancing through a 25-mile gap and reaching the River Aisne in under six hours. Eight Allied divisions, between Rheims and Soissons, were pushed back to the river Vesle. By that night they gained another 10 miles. Advancing to within 35 miles of Paris by 3 June, the Germans, having suffered significant additional casualties from Allied counterattacks, encountered supply problems and, as fatigue took its toll, they halted on the Marne on 6 June. The Third Battle of the Aisne was over.
