Without an hour's delay he issued the necessary orders, and the army retraced its steps with all speed to Ratisbon, and not stopping even there marched northward into the Upper Palatinate, to defend that conquered country against Wallenstein even at the cost of a battle.

He had but one army, and were that army destroyed, Duke Bernhard, with the prestige of victory upon him, could resume his march upon Vienna, which would then be open to him.

Therefore, having secured the safety of the capital, he fell back again into winter quarters in Bohemia.

Thus Ferdinand again owed his safety to Wallenstein, and should have been the more grateful since Wallenstein had saved him in defiance of his own orders.
At the time he fully admitted in his letters to Wallenstein that the general had acted wisely and prudently, nevertheless he was continually listening to the Spaniards, the Jesuits, and the many envious of Wallenstein's great position, and hoping to benefit by his disgrace, and, in spite of all the services his great general had rendered him, was preparing to repeat the humiliation which he had formerly laid upon him and again to deprive him of his command.
