The French Second Army crossed the Avre on a line from Lassigny northwards to Roye and Chaulnes but met the German II Corps from the 1st Army, which had arrived from the Aisne front, where new entrenchments had enabled fewer men to garrison the front line.
Joffre sent the XI Corps, which was the last French reserve, to the Second Army and began to withdraw three more corps as reinforcements.
