During this time the front of the VIth Corps had not been at all molested. General Vinoy, who had not been informed of the advance of Susbielle's Division, when its retreat was noticed caused to be opened from Fort Ivry and the adjoining works a brisk fire, which was augmented by gunboats on the Seine and armour-plated batteries on the railway. Then Admiral Pothuau advanced against Choisy le Roi and Thiais. His Marines, after driving out the Prussian fore-posts, again settled themselves firmly in Gare aux Boeufs. But the further advance failed, and General Vinoy recalled his troops, after which the fighting at Mesly ceased, and only the thunder of artillery continued till five o'clock.
After a preliminary cannonade from Valérien the Gardes-Mobiles advanced against the front of the Vth Corps about seven o'clock. They were, however, repulsed by the outposts and supporting troops in readiness, and retired at eleven o'clock.
On the northern front of Paris there occurred also a sharp fight. At mid-day Fort de la Briche, supported by field-guns and a floating battery, opened a heavy fire on the low-lying village of Epinay on the right bank of the Seine. At two o'clock Haurion's Brigade advanced, two companies of marines pressed into the place along the bank of the river, and drove out the garrison, which consisted of only one company. A second also retired from the defence-works in a northerly direction towards Ormesson. At three o'clock in the afternoon, the village, up to some still obstinately defended farms on the further side of the mill-race, fell into the hands of the French.
Meanwhile the troops of the IVth Corps had assembled, and seven batteries came into action on the overhanging heights. The infantry rushed upon the village from all sides with loud cheers, and about four o'clock, after a fierce street-fight, recovered possession of the posts which had been lost; and it was this transitory conquest that was to raise so great hopes in Tours. The losses on both sides amounted to 300 men.
Those affairs were all mere feints to facilitate the chief action; and whilst the investing troops were thus engaged and held fast at all points, two Corps of the IInd French Army at 6.30 in the morning crossed the bridges at Joinville and Nogent which had been completed during the night. After repulsing the German outposts they both deployed, and stretched completely across the peninsula between Champigny and Bry. The IIIrd Corps had taken the road along the north bank of the Marne, towards Neuilly, to cross the river there, thus threatening to compromise the position of the Saxon Corps, which therefore still detained the 47th Brigade on the right bank, though it had been assigned to the assistance of the Würtembergers. Consequently there were available to oppose the two French Corps on the left bank, only two German brigades extended over about four miles, the Saxon 48th about Noisy, and the Würtemberg 1st from Villiers to Chennevières.
