Germany’s four offensives on the Western Front have failed to break the Allies. While both sides suffer enormous casualties, the Allies have been better able to replenish their ranks from new recruits and reinforcements from America. German losses have weakened the effectiveness of the elite stormtrooper units while morale generally has fallen as the offensives have failed to bring an end to the war.
Now Ludendorff rolls the dice one more time. The German commander still sees Flanders as the best location for a decisive battle but instead his men attack further south, on either side of Reims, in the Marne and Champagne sectors. He has assembled 43 infantry divisions for this assault, which has been dubbed both the Friedensturm (Peace Offensive) and Second Battle of the Marne. As with the previous assaults, this one begins with an intense artillery bombardment of the enemy, with the Germans having assembled some 5,000 guns for the purpose.
Then things start to go wrong for the Germans. The French are ready for the German assault, forewarned by deserters. As the German assault troops move up to the trenches from which they are to attack, they are hit by French artillery. This does not stop the German assault, but the French have learned from previous battles, organising a defence in depth that smothers the Germans, preventing them from achieving the kind of gains seen at the start of the previous battles. While some progress is achieved, there is no breakthrough. By the end of the day it looks disturbingly like the Peace Offensive has failed.
