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.
Prince Frederick Charles had not been led into any change of purpose by the attack at St. Amand and the obstinate resistance at Azay. The XIIIth Corps was expected to reach Montmirail, and the XIth Epuisay, both on the 7th; the IIIrd was to continue the attack on the deep-cut channel of the Braye brook. But after the reverse experienced at St. Amand, the presence of a strong hostile force on the left flank could not be suffered to remain unregarded. Duke William had already been given verbal orders at the Head-quarter in Vendôme, to turn back forthwith to St. Amand with the 6th Cavalry Division, and in addition General von Voigts-Rhetz was ordered to support General Baumgarth if necessary with his whole Corps.
