Moving about and directing the hospital orderlies was Dr. David Clark, the surgeon in command of the hospital. He had been ordered to take charge of the Red Cross unit, who were to follow the division of American troops from the neighborhood of Chateau-Thierry to the Rhine to assist in policing Germany. With him at the moment, and aiding in a hundred small ways, was his wife, Sonya Clark. As the two nurses approached and Dr. Clark caught sight of them, he frowned with disapproval and surprise. At the instant it seemed impossible to guess what two of his nurses could be doing off duty at daybreak on this morning of all mornings. Sonya understood and nodded sympathetically. "You have been to see our troops break camp and start for Germany? I remember you asked permission. I envy you girls the experience, although we shall probably see many extraordinary sights before this day is over. We shall leave in a few hours; naturally it will not take long for us in motor cars, to catch up with the soldiers who are traveling afoot. You will be ready. I hope the sky at present is a good omen of the future." And Sonya pointed to the rose light overhead. Later in the day, the Red Cross unit from the hospital in the neighborhood of Chateau-Thierry took its place in the rear of the line of march of the American Army of Occupation toward Germany. By this time the sun was shining and the roads had become comparatively clear. Hospital supplies had been sent on ahead with a group of hospital orderlies, Dr. Clark and a corps of his physicians following soon after. In a later automobile Mrs. Clark had with her half a dozen Red Cross nurses, and in a second Miss Blackstone, the former superintendent of the hospital, an equal number. Also there was a third automobile filled with physicians and orderlies who were to keep as close to the two other cars as circumstances allowed. Across No Man's land on this November morning, from the northern end of France to the southern, were passing the victorious allied armies, three hundred thousand American troops led by Pershing to victory, and an equal or greater number of French and British. In the car with Sonya the American girls had but little to say to one another during the first part of their journey. Not only was the land before them desolate beyond description, but filled with tragic memories. Early in the afternoon, reaching the edge of a little French town, the Red Cross automobiles stopped. The occupants were in no great hurry to move forward. In advance the cavalry had swept on to prepare the way, but the infantry was going ahead slowly and would encamp for the night. This division of the Red Cross intended keeping in the background so that in case the men became ill, they could drop out and be overtaken by nurses and physicians. The girls were glad of the rest and also extraordinarily hungry, having spent the greater part of the night and every moment since daylight in preparation for the advance.
