The troops of the Austrian General Nordmann, which had occupied the plain, had fallen back under the fire of the guns. The day rose brilliant and pure, the last clouds massed by the storm were dispersed by the rays of the sun. The long files of our troops advanced without precipitation and without disorder; at the first break of day, the emperor himself had crossed the river. The Archduke Charles contemplated this scene from the heights of Wagram. His advanced posts had already been forced to give up to their enemies the ground they had occupied the day before. The Austrian general had not yet counted on the irresistible impetuosity of the torrent of men, horses, and artillery, which the island of Lobau continued to vomit on the shores of the Danube. "It is true that they have conquered the river." said the Archduke Charles to his brother the Emperor Francis, standing by his side. "I allow them to pass, that I may drive them presently into its waves." "All right," said the emperor, dryly; "but do not let too many pass." Seventy thousand French already deployed in the plain. As they defiled past, the soldiers cried, "Long live the emperor !" The town of Enzensdorf was merely a mass of ruins when Marshal Masséna commanded the attack upon it, and the little corps of Austrians defending it were soon put to the sword; while on the right, General Oudinot had taken possession of the chateau of Sachsengang. The entire army advanced, without obstacle, against the heights of Wagram; Essling and Aspern were occupied by our troops. The dispositions of the troops of the Archduke Charles were not made; he was obliged to order detached bodies to retreat, abandoning positions which were badly defended; the great battle was deferred till the morrow. A rash attack against the plateau of Wagram was repulsed, and for a moment several corps were in disorder; the retreat sounded, and the troops bivouacked at their posts. The last instructions had been given. Marshal Davout alone still remained with the emperor. The Archduke Charles did not sleep--the supreme effort of the Austrian monarchy was to be tried at the break of day. The extent of the field of battle, and the distance between the positions, presented serious difficulties for both armies. The genius of organization possessed by the Emperor Napoleon had in some measure obviated this by the care he had taken of his centre; the Archduke Charles felt it from the commencement of the combat. Obliged to send his orders great distances, he saw them badly obeyed; the left wing of his army attacked us first, whereas the right wing had been intended to take the offensive. Contrary to his custom, the Emperor Napoleon had ordered his troops to wait for the enemy.
