Allied preparations for the battle of the Marne in World War 1. Several French troops are seen in a deep crater-type defensive position. Others are seen in a shallow linear trench. French soldiers begin digging in at the side of a road, near a telephone pole. More French troops deepen their circular protective position on relatively high ground. Finally, others are seen in relatively unprotected positions in a grassy field. Several French soldiers stand near a Schneider CA1 tank. American troops are seen dimly in the far background, as they enter the area single file. Closer view of American Expeditionary Forces troops moving into position along a tree line.
