On the right wing the 44th Brigade, in its advance on Nogent le Rotrou, also had had a sharp encounter. It carried the enemy's position at La Fourche, and captured three guns, with a large number of prisoners. The main body of the Corps (the XIIIth) reached Beaumont les Autels and Brou, but the cavalry failed to penetrate the woods to the north of Nogent.
January 6th.—At six in the morning the advanced guard of General Baumgarth's detachment started on march to Prunay, but the main body could not follow, since it was attacked in force at about half-past nine. With the object of observing the enemy, the infantry had been scattered in detached posts in a wide extension from Ambloy to Villeporcher, and only a small reserve remained at La Noue. The fight soon assumed greater expansion, and the defence with difficulty maintained the line Les Haies—Pias, the turning of the German left flank being seriously threatened, upon which the 6th Cavalry Division moved up, but could only enter the fight with one horse battery. The reserve, however, moved up along the high road to Château Renault and repulsed the enemy, who had already forced his way into Les Haies. But when he renewed the attack in strong columns and developed four batteries against the place, the reserve was obliged to retire behind the Brenne.
Meanwhile the 16th Regiment, which had already reached Ambloy on its march to Vendôme, turned back to St. Amand in support, and the just assembled 38th Infantry Brigade deployed between Neuve St. Amand and St. Amand with a strong force of cavalry on its flanks. But as by some mistake St. Amand was evacuated, Duke William of Mecklenburg (commanding 6th Cavalry Division) ordered a further retreat. The infantry, however, had already come to a halt at Huisseau and took quarters there. The advanced guard turned into Ambloy; the cavalry fell back partly on that place and partly on Villeromain.
During the engagement about St. Amand the Xth Corps itself advanced on Montoire in two columns along the left bank of the Loire, leaving on its right a battalion in front of Vendôme to secure the debouche of the IIIrd Corps through that place.
When the 20th Division reached St. Rimay at about one o'clock, it found the heights on the opposite side of the Loir occupied by General Barry's troops. The massed German batteries were brought up to the southern ridge of the valley and soon drove the French off the broad flats; but the defile of Les Roches in the front remained quite unassailable. The broken bridge at Lavardin, lower down the stream, was therefore made practicable by the pioneers. The 19th Division having meanwhile reached that place, several battalions crossed from the south side to attack Les Roches, and easily dislodged the French. As darkness came on, preventing any further advance, the Corps found quarters in and about Montoire.
The Commander of the IIIrd Corps had intended to make a halt on this day before Vendôme, and only push forward his advanced guard as far as the Azay brook; but this detachment soon met with so stout opposition, that the main force was compelled to advance to its assistance. General de Jouffroy, with intent to disengage General de Curten, had renewed the attack on Vendôme, and so the advanced guard of the 5th Division, approaching Villiers at about half-past one, found the 10th Jäger Battalion, which had accompanied the march of its Corps along the right bank of the Loir, engaged at that place in a sharp fight which had already lasted four hours. The advanced guard brought up its two batteries on to the plateau north of the village, and the 48th Regiment made its way forward to the slope of the lower Azay valley, the broad flat meadows of which were commanded by the French long-range rifles and completely swept by the fire of the artillery. And here then the enemy came over to the attack in dense swarms of sharp-shooters.
The 8th Regiment presently came up in support, and after a short fight took possession of Le Gué du Loir on its left flank; then the further reinforcement arrived of the 10th Infantry Brigade, and by degrees the number of Prussian guns increased to thirty-six. The French artillery could not endure their fire, and within half an hour it was possible to turn it on the hostile infantry. At about half-past four the German battalions crossed the valley, made themselves masters of the vineyards and farms on the opposite heights, and finally stormed Mazange. Under cover of the darkness the French retired to Lunay.
Further to the right the advance guard of the 6th Division, having left Vendôme at eleven o'clock, found the battalion left by the Xth Corps at Courtiras fighting hard against a very superior force of the French. The 11th Brigade advanced on the Azay ravine, though not without heavy loss, and when at about half-past three the 12th also came up, and the artillery went to work vigorously, Azay was successfully stormed and the force established itself firmly on the heights beyond. Repeated counterstrokes of the enemy were repulsed in succession, and by five o'clock the fighting ended with the retirement of the French.
The IIIrd Army Corps took up quarters between the Azay stream and the Loir. A detachment occupied Danzé, higher up the river. The Corps lost thirty-nine officers and above 400 men, but captured 400 prisoners.
In the course of the day the IXth Corps crossed the upper Loir about Fréteval and St. Hilaire, without opposition, and advanced along the high road to St. Calais, as far as Busloup. The XIIIth remained at Unverre, Beaumont, and La Fourche.
