4. Battle Summary General Erich Ludendorff convinced that an attack in Flanders was the best route to German victory. He wanted to lead the Allie troops away from the main event, the resulting attack in Marne, launched on the back of the German capture of the strategically important Chemin des Dames ridge near the Aisne river on May 27, 1918. Ludendorff attempted to divide and conquer the French forces by having 23 divisions of the German 1 st and 3 rd armies attack the French 4 th army east of Reims while 17 divisions of the 7 th army assisted by 9 th army would attack the French 6 th army west of the city. French forces were joined by 85,00 US troops as well as a portion of British Expeditionary Force. Germans had found out the French had set up false trenches when they began their attack. The real trenches lay further on, the deceptive strategy had been put into place by Philippe Petain. As the Germans approached the rel Allied front lines they were bombarded by French and American fire, suffered heavy casualties, setting the Allies up for their major counter attack they would launch on July 18.
