The valley itself ranges from one to two kilometres in width and the green forest-clad mountains rise on each side to a height of three hundred to four hundred metres. In the floor of the valley were orchards, open fields, and small towns. Down the centre of it was the broad road which continued up and over the divide into France. It formed, aside from an aerial tramway that the French constructed over the divide especially for this war, the only avenue of traffic for the supplies of ammunition, guns, food, etc., for the armies that were situated in this district. As a consequence it was night and day a scene of activity throughout its entire length. Down the valley this road had two important branches, one at a point six kilometres from Moosch and another at eight. Both these branches followed the course of small creeks that feed the river Thur, up and up the small valleys through which the streams flowed, then turned up the mountain-side and climbed to the top of one of the larger hills. One route was used for traffic ascending, the other for all descending, except for any that was required by Red Cross Stations or artillery posts along the way. In this manner much passing of the up and down streams of wagons, mules, motor trucks, etc., which would have been well-nigh impossible on these steep, narrow roads, was avoided.
On the mountain-top was a small space, somewhat cleared of the forest growth, where three roads met, two that have already been mentioned and another that went over one shoulder of the mountains and down to an advance poste de secours, practically under Hartmannsweilerkopf itself. In one angle of the "Y" formed by these roads were a few roughly constructed buildings for taking care of the wounded, cooking, etc., and in another nothing but the steep slope of the mountain with a cabin or two tucked close against it amid the pine woods. In the last angle was a small graveyard where lay the men who had died from wounds there at the station or had been killed during the bombardment of some local artillery post or of the road. Next to this graveyard was a limited parking-space for the ambulances, and beyond this the cosy little building, the poste de secours, where the French stretcher-bearers and American drivers ate and slept together when not at work.
This place was popular among the Americans, at first, at least, before the Germans captured a colonel with telltale maps upon his person, and their guns began to find and make uninhabitable a spot that had once seemed a secure retreat. Up in the fresh air and ozone of the pine woods, it was hard, in spite of the graveyard near by and the ever-passing stream of ammunition wagons or pack trains, not to think of this place as a pleasant vacation ground. The Frenchmen, too, were wonderful companions, playful as boys of ten, and kind and generous to a fault. After a snowstorm, unless there was a great deal of work, there was sure to be a tremendous snow battle in progress, and the Frenchmen, old territorials some of them, forty to fifty to sixty years of age, would be as hard after one another as boys in their mimic wars. Their generosity went so far as surrendering their bunks to the Americans while they slept out in the ambulances. At times the little poste de secours would be a scene of revelry, the professional entertainer taking part in the programme of the evening with the country songster. More often, however, the Frenchmen were busy and the Americans would amuse themselves with some deep, protracted argument or read the latest book on the war that some kind friend had sent to a member of the Section. At night the little hut had its bunks filled to overflowing, but sleeping was generally good, unless your bedfellow happened to be a soldier dreaming of battle or a mule-driver dreaming of swearing at his mules. At night there were always one or two interruptions, especially whenever an ambulance-driver was wanted. Those who were sent to call him always succeeded in waking the whole lot of sleepers before finding the man whose turn it was to "roll."
WINTER DAYS IN ALSACE
This "night rolling," as it is called, is not the easiest thing to do by any means. The road, steep and narrow and rough at any time, would in snowy or rainy weather cause an occasional sinking of the heart to the best of drivers. To these difficulties was added the necessity of passing the slowly descending trains of ammunition wagons and mules. On one stretch of road no lights were permitted, as they would have disclosed its location to the Germans. On nights when there was no moonlight and heavy mists enshrouded the mountains, it was a trying nerve strain to come down this bit of road. The history of every car would be full of stories of narrow escapes from running into wagons, mules, or men, or running over the edge of the road or against the side of the hill. These difficulties and trials, however, weren't what would occupy the mind when the German shells began breaking near; they lose their importance entirely. One can get used to the blind driving on a dark night, but never to the high-explosive shells. Even on the floor of the valley where the road is level, the thrills might not cease, for here it has been a common experience to run into an unlighted wagon or to be smashed by a heavy, ponderous motor truck. Perhaps it would be a mere matter of getting ditched in the effort to get out of the way of the latter. But with the Ford this was never a serious trouble, as eight or ten men, and they were always to be had in a few moments on any part of the road, could quickly lift it out and put it on the road again. Out of the most severe smash-ups the Fords have emerged supreme and in every case proved the statement that a "Ford car can be bent but not broken."
At the hospital the wounded would be taken out, new blankets and stretchers put in, the gas tank filled, and the car sent up the mountain again to wait for more blessés unless it was time for the driver to turn in and get a bit of sleep.
During the day a call would very often mean a trip down the other side of the mountain to the advance posts nearer Hartmannsweilerkopf. While day driving hasn't the terrors of night driving, yet the road near these two posts and the posts themselves were more often the object for German fire, and it was with a little feeling of dread that one went there. The road down to it was exceedingly steep in places and few cars could make the return trip with a full load. There never was any anxiety about stalling, however, for a little assistance from eight or ten soldiers would send the car on its way again. Many a time a driver would unconsciously arrive at the posts at a time of bombardment and be told to leave his machine and hurry to an abri. An abri is a cave or dug-out in the side of the mountain offering protection against the German shells. All along the mountain roads these little places of refuge began to appear after the Germans had learned how to drop shells consistently near these routes, and to see them thus was a real comfort to the mind whenever the whistle of a shell sounded unpleasantly loud and near. These caves were not always in a finished state, as a big broad-shouldered driver learned to his discomfort and the vexation of his two comrades. They were taking a look at Hartmanns from a portion of the road whence it can be seen, when the portentous sound of the flying shells began which kept coming nearer and nearer. The Americans turned and ran up the road to one of these abris, the big man leading. He darted for the cave entrance, but his body was just too big and he was wedged tightly between the stone sides, while his two comrades pounded on his back clamoring for admittance. He decided it was more comfortable and safe flat against the rocks in front of the car, and safer, too, than in a hole the entrance to which might so easily be closed.
