The column first struck the enemy near Villechauve at mid-day. A thick fog prevented the employment of the artillery, and it was at the cost of heavy loss that Villechauve, Pias, and various other farmsteads were captured. Villeporcher and the adjacent villages remained in possession of the French, who at about two o'clock advanced by the high road to the attack with several battalions. The weather had cleared, and it was soon evident that this offensive was only intended to mask the beginning of the enemy's retreat to the westward. The troops took quarters where they stood, and the reinforcements forwarded to them remained at St. Amand. 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 Richardiere 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 Sarge 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.
