The order from the Army Head-quarter that the XIIIth Corps was to march to Montmirail, had been issued on the presumption that it would have reached Nogent le Rotrou on the 6th, whereas in fact, as has been shown, it had remained at La Fourche, Beaumont, and Unverre. The Grand Duke, who expected to experience a stout resistance, did not pass to the attack of Nogent till the 7th. When the 22nd Division arrived there, it found all the villages deserted in the Upper Huisne valley and was able to enter Nogent without any fighting at two o'clock. It took up quarters there, the 4th Cavalry Division at Thirion Gardais; and only an advanced guard followed the enemy. It found the wood near Le Gibet strongly occupied, and did not succeed in forcing it till after nightfall. The French had retired to La Ferte Bernard. The 17th Division had at first followed in reserve. But at one o'clock, in consequence of the reports brought in, the Grand Duke detached it southward to Authon; and in order to follow the Head-quarter instructions as closely as possible he did at least push a detachment of two battalions, two cavalry regiments, and one battery towards Montmirail, under the command of General von Rauch. _January 8th._--Finding on the morning of the 8th that the enemy was not advancing to the attack of St. Amand, General von Hartmann at nine o'clock sent back the troops which had crossed the river to his support. At ten o'clock also he received instructions to join the Xth Corps; but the French still continued to hold Villeporcher and the forest lying behind it, and were also drawn up across the Chateau Renault high road in a very advantageous position behind the Brenne. The General recognized the necessity of making a decisive stand here, and took the best means to that end by acting himself on the offensive. Supported by the fire of his battery, and accompanied by the cavalry on either flank, six companies of the 60th Regiment marched on Villeporcher, drove back its defenders in flight into the forest of Chateau Renault, and took 100 prisoners. On the left the 9th Uhlans drove the Chasseurs d'Afrique before them. Not till darkness had set in did General von Hartmann proceed in the direction of Montoire.
