There were from 10,000 to 12,000 men in our force, which now ranked as the fourth division of the 21st army corps. Nearly all the men of both brigades were Breton Mobilises, adjoined to whom, however, perhaps for the purpose of steadying them, were three or four very small detachments of former regiments of the line. There was also a small contingent of the French Foreign Legion, which had been brought from Algeria. Starting from Yvre l'Eveque towards, noon on December 4, we marched to Ardenay, where we spent the night. The weather was fine and dry, but intensely cold. On the 5th we camped on some hills near the town of Saint Calais, moved only a mile or two farther on the 6th--there being a delay in the receipt of certain orders--then, at seven o'clock on the 7th, started in the direction of Vendome, marching for about twelve hours with only the briefest halts. We passed from the department of the Sarthe into that of Loir-et-Cher, going on until we reached a little place called Ville-aux-Cleros, where we spent the night under uncomfortable conditions, for it snowed. Early the following day we set out again, and, leaving Vendome a couple of miles or so away on our right, we passed Freteval and camped on the outskirts of the forest of Marchenoir. The night proved bitterly cold, the temperature being some fourteen degrees (centigrade) below freezing-point. I slept huddled up in a van, but the men generally were under canvas, and there was very little straw for them to lie upon, in such wise that in the morning some of them actually found their garments frost-bound to the ground! Throughout the night of the 10th we heard guns booming in the distance. On the 11th, the 12th, and the 13th December we were continually marching, always going in the direction of the guns. We went from Ecoman to Moree, to Saint Hilaire-la-Gravelle, and thence to the Chateau de Rougemont near Freteval, a spot famous as the scene of a victory gained by our Richard Coeur-de-Lion over Philip Augustus. The more or less distant artillery fire was incessant both by day and by night; but we were only supporting other divisions of the corps, and did not find ourselves actually engaged. On the 15th, however, there was very sharp fighting both at Freteval and Moree, and on the morning of the 16th our Gatlings went forward to support the second division of our army corps, which was being hard pressed by the Germans. All at once, however, orders for a general retreat arrived, Chanzy having at last decided to fall back on Le Mans. There was considerable confusion, but at last our men set out, taking a north-westerly direction. Fairly good order prevailed on the road, and the wiry little Bretons at least proved that their marching powers were unimpaired. We went on incessantly though slowly during the night, and did not make a real halt until about seven o'clock on the following morning, when, almost dead-beat, we reached a little town called Droue.
