Blucher had received his orders late in the morning, and could not commence the attack so early as that upon the left. About eleven o'clock, having contented himself with observing and blockading a body of French troops, who occupied the village of St. Denis, he directed the columns of General Langeron against the village of Aubervilliers, and, having surmounted the obstinate opposition which was there made, moved them by the road of Clichy, right against the extremity of the heights of Montmartre, whilst the division of Kleist and D'Yorck marched to attack in flank the villages of La Villette and Pantin, and thus sustain the attack on the centre and right of the French. The defenders, strongly intrenched and protected by powerful batteries, opposed the most formidable resistance, and, as the ground was broken and impracticable for cavalry, many of the attacking columns suffered severely. When the divisions of the Silesian army, commanded by Prince William of Prussia, first came to the assistance of the original assailants upon the centre, the French concentrated themselves on the strong post of La Villette, and the farm of Rouvroy, and continued to offer the most desperate resistance in defence of these points. Upon the allied left wing the Prussian guards, and those of Baden, threw themselves with rival impetuosity into the village of Pantin, and carried it at the point of the bayonet. During these advantages, the Prince Royal of Wirtemberg, on the extreme left of the allies, had forced his way to Vincennes, and threatened the right of the French battalions posted at Belleville, as had been projected in the plan of the attack. General Rayefski renewed the suspended assault upon these heights in front, when he learned that they were thus in some measure turned in flank, and succeeded in carrying those of Romainville, with the village. Marmont and Oudinot in vain attempted a charge upon the allied troops, who had thus established themselves on the French line of defence. They were repulsed and pursued by the victors, who, following up their advantage, possessed themselves successively of the villages of Belleville and Mesnilmontant, the Butte de St. Chaumont, and the fine artillery which defended this line.
