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.
