The various feigned attacks of the Parisian garrison were without effect, and produced no alteration in the dispositions made on the German side. An advance from St. Denis against Stains was repulsed, and two gunboats on the Seine had to go about in consequence of the fire of four field batteries on Orgemont. The trivial sortie on Chatou was scarcely heeded. General Vinoy indeed led forward a large force along the right bank of the Marne, but that was not till the afternoon, when the fight at Le Bourget was over. The Saxon outposts retired into the fighting position near Le Chenay. One of the battalions massed there drove the enemy out of Maison Blanche that same evening, another made a grasp at Ville Evrart, where fighting went on till midnight; it lost seventy men, but brought in 600 prisoners. Next morning the French abandoned Ville Evrart, under heavy fire from the German artillery on the heights on the opposite side of the river. Paris had now been invested for three months. The always distasteful expedient of a bombardment of a place so extensive could not of itself bring about a decisive result; and on the German side there was the full conviction that only a regular siege could accomplish the wished-for end. But the operations of the engineers had to be delayed till the artillery should be in a position to co-operate with them. It has already been shown that the siege-artillery had been first employed against those fortified places which interrupted the rearward communications of the army. There were indeed 235 heavy pieces standing ready at Villacoublay; but it had proved impossible as yet to bring up the necessary ammunition for the attack which, once begun, must on no account be interrupted.
