Fayolle stayed in Italy until March 1918, when he was recalled to France and put at the head of the 55 division-strong Army Group Reserve, with which he played a role in stopping the last significant German offensives. After the allied victory in the Second Battle of the Marne, he took part in the allied counteroffensive until the end of the war. From July until November Fayolle's command reduced the Marne Salient and drove towards the Rhine.
