Fifty yards away was another ambulance with its wheels buried to the hubs in the loose sand. Red Cross nurses and men wearing the emblem on their arms and caps were passing here and there, assisting the injured with "first aid," temporarily bandaging heads, arms and legs or carrying to the rear upon a stretcher a more seriously injured man. Most of this corps were French; a few were English; some were Belgian. Our friends were the only Americans on the field.
