Charcoal on white paper of two Army ambulances responding to a "hurry call" or emergency summons on the night of May 30, 1918, in the Toul Sector of France. The ambulances (possibly Ford Model T's) have large medical crosses on the side. American soldiers in uniform march along the road to the right of the ambulances. On the left side of the road, wounded soldiers walk in the opposite direction of the ambulances.
