Meantime Davout had attacked the left. While he fought he was steadily reinforced, until at one time, about midday, over a third of the army was concentrated under his command. The Austrians opposed to them could not, even with their vantage of high ground, withstand the ever stronger pressure, and slowly rolled back northward in a curve. Eugene captured Wagram, and then turned in that direction to unite with Macdonald, whose division had joined that of Wrede, and had been steadily pushing back the enemy's line toward the same point. They were supported by Davout and Oudinot. The Austrians on the right were then once more dislodged and compelled to withdraw on the highway to Bruenn. It was about two in the afternoon. Davout had been ordered to wait for a signal to make the decisive advance. It was given, and as Oudinot rushed up the heights at Parbasdorf, his comrade appeared from Markgrafneusiedl, driving the enemy before him. A breach in the opposing line was made at once, and the whole Austrian wing, being thus disorganized, hurried back to reform if possible beyond Wagram, cross the Russbach, and join the main army. They were successful. The French right halted just beyond the village which gave its name to the battle. Lasalle, a brilliant light-horse general, was killed in the last charge, and both armies bivouacked for the night. Next morning Charles withdrew toward Znaim, Massena, Davout, and Marmont following with the van of Napoleon's army. Several skirmishes took place between portions of the Austrian rear and various corps of the French van, in which the latter were decidedly checked. Marmont was obliged to assume the defensive under the walls of Znaim. The Austrian losses at the battle of Wagram were computed at twenty-four thousand, including seven hundred and fifty-three officers. Those of the French were certainly not less, if we include seven thousand who were taken prisoners. They lost, moreover, twelve standards and eleven guns. In the early hours of July sixth, Charles had despatched an adjutant to Presburg with orders to the Archduke John to march at once and attack the enemy's rear. The story at first accepted was that the messenger found the bridges over the river March destroyed, and arrived six hours too late for his errand to be successful. There were, however, many at the time who attributed criminal negligence to John, among them his own brother, the commander-in-chief. For a time, by means of court intrigue and persistent misrepresentation, the blame was put, not on John, but on Charles, but eventually the former was found guilty and banished to Styria. Had the latter's plan succeeded, Napoleon would have had a different task--a task so difficult that the issue of the battle might well have been doubtful, if not disastrous. As it was, the victory was dearly bought, and the Austrians were not demoralized.
