The artillery of the guard arrived at a gallop, supporting by its hundred guns the impetuous attack of the centre: the Austrians recoiled from this enormous mass, the irresistible impulse of which nothing could stay. Macdonald had already reached Sussenbrunn, where the archduke and his generals had concentrated their last effort; and the French columns were stopped by their desperate resistance. For a moment they seemed destined to retreat in their turn; but Davout had succeeded in his attack against the heights of Neusiedel. The plateau of Wagram was in our hands; General Oudinot had effected his junction, after taking the position of Baumersdorf; and the Prince of Hohenzollern retreated before them. In vain the Archduke Charles had hoped to see his brother, the Archduke John, arrive in time to restore their chance; the struggle lasted for more than ten hours--all the positions had fallen into our power; the retreat of the Austrian army commenced, regular and well ordered, without precipitation or rout. Disorder, on the contrary, showed itself in the ranks of the conquerors, when, at the last moments of the struggle, some soldiers of the vanguard of the Archduke John appeared in the environs of Leopoldsdorf. The young troops, already disbanded in the joy of the victory--the servants of the army, the sutlers, the carriers of the wounded, were seized with a panic terror, and fell back with loud cries on the main body of the army, announcing that the enemy were returning to crush us. It was too late; the Archduke John had slowly executed the orders tardily received. His arrival could not change the issue of the battle; he fell back upon Hungary. The Archduke Charles had taken the road to Bohemia before the Emperor Napoleon was well informed of his march. The pursuit was, therefore, divided between Bohemia and Moravia. The forces of the enemy were dispersed during their retreat. The archduke had with him about 60,000 men, when General Marmont, with a corps of only 10,000, rejoined him at Znaïm, on the road to Prague.
