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.

Gustavus remained eight days before Ingolstadt, and then, finding that the reduction of the place could not be effected without the loss of much valuable time, he raised the siege.  On his march he took possession of Landshut and forced it to pay a ransom of 100,000 thalers and to receive a garrison, and then continued his way to Munich.

The Bavarian capital surrendered without a blow on the 17th of May.  Gustavus made a triumphal entry into the town, where he obtained possession of a vast quantity of treasure and stores.  Here he remained some little time reducing the country round and capturing many cities and fortresses.  The Green Brigade had suffered severely at Ingolstadt.  On the evening of the 19th of April the king, expecting a sally, had ordered Hepburn to post the brigade on some high ground near the gate and the soldiers remained under arms the whole night.

The glow of their matches enabled the enemy to fire with precision, and a heavy cannonade was poured upon them throughout the whole night.  Three hundred men were killed as they stood, Munro losing twelve men by one shot; but the brigade stood their ground unflinchingly, and remained until morning in steady line in readiness to repel any sortie of the enemy.
