Already, before touching Donauwerth, Napoleon's orders had begun the concentration of his forces. Masséna was at Augsburg, and received the order to march upon Neustadt, and similarly Davout left Ratisbon to advance to the same place. The Archduke Charles was also striving to reach it, hoping to gain upon the French by speed, and pass between the divisions posted at Ratisbon and Augsburg. This manoeuvre was baffled by Napoleon's prompt decision. "Never was there need for more rapidity and activity of movement than now," he wrote on the 18th to Masséna. "Activity, activity, speed! Let me have your assistance." The emperor's lieutenants did not fail him in this brilliant and scientific movement, everywhere executed with an ability and precision worthy of the great general who had conceived it. The Archduke Charles was a consummate tactician, but often his prudence degenerated into hesitation--a dangerous fault in presence of the most overpowering military genius whom the world had yet beheld. Napoleon himself said of Marshal Turenne that he was the only general whom experience had made more daring. A long military experience had not exercised that happy effect on the archduke; he still felt his way, and neglecting to take advantage of the concentration of his forces, dispersed the different parts of his army. The chastisement was not slow in following the fault. On the 19th, Marshal Davout, ascending the Danube from Ratisbon to Abensberg, met and defeated the Austrian troops at Fangen, thus being able to effect his junction with the Bavarians. On the 20th, the emperor attacked the enemy's lines at several points, and forced his way through them towards Rohr after several active engagements, thus securing the point of Abensberg, and separating the Archduke Charles from General Hiller and the Archduke Louis. On the 21st, this last part of the enemy's army precipitated itself in a body upon the important position of Landshut, where all the Austrian war material was collected, with a large number of wounded; but at the same moment the emperor himself came up, eagerly followed by Lannes and Bessières, commanding their regiments. Masséna also made haste to join them. The bridges on the Isar were all attacked at once, and bravely defended by the Austrians: when carried they were already in flames. The Archduke Charles, however, attacking Ratisbon, which Davout was obliged to leave protected only by one regiment, easily took possession of that important place, commanding both banks of the Danube. He was thus, on the 22nd, before Eckmühl opposite Davout. Informed of this movement, which he had partly guessed from the noise of the cannon on the 21st, the emperor directed the main body of his army towards Eckmühl. His troops had already been fighting for three days, and Napoleon asked a fresh effort from them. "It is four o'clock," he wrote to Davout, "I have resolved to march, and shall be upon Eckmühl about midday, and ready to attack the enemy
