The Imperialist position was tremendously strong, being unassailable on the right and covered in the front by the marshy ground. It could still have been defended with every prospect of success by a determined general, but the two best Imperialist commanders were hors de combat, and Maximilian of Bavaria, the nominal generalissimo, had no military experience. The army, too, was disheartened by the first success of the Swedes and by the loss of the general whom they regarded as well nigh invincible. Tilly had now recovered his senses, but was suffering intense agony from his wound, and on being consulted by Maximilian he advised him to fall back, as the destruction of his army would leave the whole country open to the Swedes. The Imperialists accordingly evacuated their position and fell back in good order during the night on Neuberg, and then to Ingolstadt. Rain and Neuberg were occupied the next day by the Swedes. Gustavus despatched Marshal Horn to follow the retreating enemy to Ingolstadt, and he himself with the rest of his army marched up the Lech to Augsburg, which was held by Colonel Breda with four thousand five hundred men. The Imperialists had broken down the bridge, but Gustavus immediately built two others, one above and the other below the city, and summoned it to surrender. Breda, hearing that Tilly was dying, Altringer severely wounded, and that no help was to be expected from Maximilian, considered it hopeless to resist, and surrendered the town, which Gustavus, attended by the titular King of Bohemia and many other princes, entered in triumph on the following day, April 14th. The capture of Augsburg was hailed with peculiar satisfaction, as the city was regarded as the birthplace of the Reformation in Germany. Leaving a garrison there the king retraced his steps along the Lech to Neuberg, and marched thence to join Marshal Horn in front of Ingolstadt. This town was one of the strongest places in Germany and had never been captured. It was now held by a formidable garrison, and the Imperialist army covered it on the north. Tilly had implored Maximilian to defend it and Ratisbon at all hazards, as their possession was a bar to the further advance of Gustavus. The king arrived before it on the 19th, and on the following day advanced to reconnoitre it closely. The gunners of the town, seeing a number of officers approaching, fired, and with so good an aim that a cannonball carried off the hindquarters of the horse the king was riding. A cry of alarm and consternation burst from the officers, but their delight was great when the king rose to his feet, covered with dust and blood indeed, but otherwise unhurt. On the following day a cannonball carried off the head of the Margrave of Baden-Durlach, and on the same day Tilly expired. With his last breath he urged Maximilian never to break his alliance with the emperor, and to appoint Colonel Cratz, an officer of great courage and ability, to the command of his army.
