The Xth Corps, awaiting the return of the latter, remained in its quarters about La Chartre; only the 14th Cavalry Brigade went on up to La Richardière to establish connection with the IIIrd Corps. But it did not succeed in taking the village with dismounted troopers.
General von Alvensleben[64] hoped to overtake the French on the hither side of the glen of Braye, and by turning their left wing to drive them on to the Xth Corps, whose co-operation had been promised. The IIIrd Corps advanced in the direction of Epuisay, leaving one brigade to garrison Mazange, and when tidings reached it on the march that the French had evacuated Lunay and Fortan, that brigade also followed by way of the latter village.
Epuisay was found to be strongly held, and in the meantime the advanced guard of the IXth Corps, advancing from Busloup, also arrived there. But it was not till half-past one that the French were expelled from the little town, which they had strongly barricaded; and on the hither side of the Braye they renewed their resistance in the numerous hamlets and farmsteads. A long fire fight was kept up in the thick fog; but at length, at about four o'clock, the 12th Brigade pushed forward to the edge of the valley. The 9th Brigade took possession of Savigny without meeting any serious opposition, and Sargé was stormed in the dusk.
The IIIrd Corps had lost forty-five men and had taken 200 prisoners. It found quarters behind the Braye, but threw forward outposts on its western bank. The IXth Corps found shelter in and about Epuisay, and thus, as a matter of fact, two corps were now crowded on one of the few available roads. The 2nd Cavalry Division went to the right, towards Mondoubleau, to make connection with the XIIIth Corps. The French retreated to St. Calais.
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.
