Here the Bavarian Corps and the 4th Cavalry Division were already engaged in a fight, having previously driven the French out of Bricy and Janvry. When the artillery had for some time been in action, General von der Tann passed to the assault at about twelve o'clock. But the French did not wait for this; they beat a hasty retreat, leaving some of their guns in the defences.
The 2nd Cavalry Division took up the pursuit. The 4th Hussars of the 5th Brigade, trotting forward through Montaigu, charged a dismounted French battery and seized all its guns; another near Ormes was left to be carried off by the horse battery. From thence a strong body of French horse suddenly appeared on the left flank of the 4th Brigade as it was crossing the Châteaudun road. But the Blücher Hussars, promptly wheeling into line, drove the enemy back through the village on Ingré.
The 4th Cavalry Division was placed on observation on the right flank of the Detachment; and the Hussars of the 2nd Life Regiment here rode down 250 men forming the escort of a waggon column escaping by the road to Châteaudun, and captured the convoy.
While the Germans were thus converging on Orleans from the east and north, in the west the XVIIth French Corps and the 1st Division of the XVIth were still in the field about Patay and St. Péravy. General Chanzy had assembled the latter about Coinces, and, to protect himself against its threatened attack on his flank, General von der Tann formed front at Bricy with his 3rd Infantry Brigade, the Cuirassiers, and the artillery reserve. The 4th Cavalry Division marched on Coinces, where General von Bernhardi, clearing a wide ditch with four squadrons of Uhlans, drove a body of French horse back on St. Péravy without its having been able to do more than fire one carbine-volley. Other squadrons of the 9th Brigade rode down the French tirailleurs, and pursued the cavalry till it reached the protection of strong bodies of infantry. The 8th Brigade was in observation toward Patay, and after that place had come under the fire of a battery and been abandoned, General Chanzy gave up all further attack and retired behind the forest of Montpipeau.
The 2nd Cavalry Division now made for the Loire immediately below Orleans. Its artillery destroyed a bridge at Chapelle over which a baggage-train was passing, and compelled the French troops, which were marching towards Cléry along the further bank, to flee back to Orleans. Two military railway-trains from thence were not to be stopped by the firing, but a train coming from Tours, in which, as it happened, was Gambetta himself, returned thither with all speed.
