The orders from the Army Head-quarter had not reached the XVIIIth Corps until midnight. It had moreover to accomplish a difficult march by deeply snowed-up woodland paths. This entailed crossings, not only between the flank columns of its 1st and 3rd Divisions, but even with the Division Crémer at Lyoffans. This Division had only by dint of the greatest exertion reached Lure during the night, and could not get further on to Béverne until nine in the morning. A fresh delay was occasioned by the order to bring up in front of the infantry the artillery—even the reserve artillery which was marching in the very rear; and thus it happened that the XVIIIth Corps did not succeed in deploying two of its Divisions opposite Luze and Chagey till between 12 and 2 in the afternoon.
The 1st Division occupied Couthenans with one battalion, and brought up five batteries on the reverse slope of the heights to the north of that place. But the fire from the opposite bank prevented their further progress, and in a short time several of the batteries had but two guns left fit for action, although the Germans, in view of the difficulty of replenishment, used their ammunition as sparingly as possible. At three o'clock there was a pause in the artillery fight, which however was resumed energetically on the arrival of reinforcements, when the artillery of the XXIVth Corps coming from Byans took part in it. An infantry attack on a large scale was not yet attempted.
There was scarcely more vigour in the advance of the 3rd Division against Chagey, which was occupied only by a Baden battalion; yet it was from here that the outflanking movement of the German right wing by turning Mont Vaudois was to be gone upon. The wood reached to the first houses of the village, and the only difficulty was the climb up the steep face of the height. Two French battalions suddenly burst from the gorge south of it, and drove in the Baden outposts; the further attack was to have been supported from Couthenans on the south, but the infantry advancing from thence found itself forced to turn back by the fire from the opposite bank. Only by a renewed effort did the Zouaves succeed in entering Chagey, where a stubborn fight raged in and around the houses. Meanwhile two Baden battalions came up, who, at five o'clock, drove the enemy out of the village back into the wood. Fresh reinforcements hastened to the support of the latter from the reserve near by, the short winter's day was over, and here during the night the French attempted nothing further. The 2nd Division of the French Corps had only advanced as far as Béverne, the cavalry had not moved from Lyoffans.
The Division Crémer, despite its late arrival at Lure, had continued the march in the early morning. After the above-mentioned crossings and resultant delays the 1st Brigade advanced on Etobon, and there at noon it engaged in a fight with a Baden detachment under the command of General von Degenfeld. When the 2nd Brigade also came up, the 1st moved forward through the Bois de la Thure, with intent to cross the Lisaine above Chagey. Parts of the roads had first to be made practicable by the pioneers, involving considerable delay. The 2nd Brigade then followed in the dark, having left a detachment in observation at Etobon. A fresh collision with some Baden detachments determined General Crémer to extinguish all the watch-fires. His troops remained under arms throughout the hard winter night.
On the German side, all the troops not on guard duty found shelter in the neighbouring villages, the pioneers only being kept at work with their pickaxes. The actions had cost both sides about 600 men, without bringing about any decisive result; but every day was a gain to the defenders.
General Von Werder, on the heights north of Héricourt, had received constant reports regarding the course of the fighting from the General Staff officers sent out in various directions, by which he was able to regulate the abstraction from the reserves of reinforcements to the fighting line. The diminution of the ammunition was a cause of anxiety, since a consignment announced from Baden had not yet arrived.
General Bourbaki informed his Government that he had taken Montbéliard, it was true without the castle, had occupied the villages on the west bank of the Lisaine, and that he would attack on the 16th. He had learned from General Billot that the German right wing extended considerably beyond Mont Vaudois, whence he inferred that important reinforcements had reached the enemy, whose strength he estimated at 80,000 to 100,000 men. Nevertheless he anticipated a fortunate issue for the outflanking operation by fetching a yet wider compass to the left.
January 16th.—At half-past six on the morning of the 16th the Germans again stood to arms in the positions of the previous day.
The French again began the attack with their right wing. From the loopholed houses they fired on the Landwehr company holding the castle of Montbéliard, causing some loss among the latter as well as among the gunners. The summons to surrender was disregarded, and the fire of the fortress artillery was used to such good purpose against two batteries which showed themselves on the neighbouring height, that these were obliged to retire, leaving behind them two guns. Neither could they advance from a new position they had taken up at the farm of Mont Chevis, and where they had been reinforced by three batteries, against the fire from La Grange Dame, although the cannonade continued until dark. No attempt was made from Montbéliard to pierce the German line.
Further to the left the reinforced 1st Division of the French XVth Corps advanced on Béthoncourt. At one o'clock the fire of its artillery from Mont Chevis and Byans obliged a Baden battery to limber up, and it was then directed on the village. Large bodies had been massed in the neighbouring forest, from out which at three o'clock they advanced. General Glümer had meantime despatched reinforcements to the threatened front. Two determined attempts pushed close up to the village were frustrated by the destructive artillery and rifle fire of the defenders. A third attack made with a whole brigade at four o'clock, was not permitted even to approach. The losses on the French side were considerable, and the snowy field was strewn with the fallen. Some unwounded prisoners were also taken.
