Before these measures could be taken, and the necessary points settled between the regency and their minister, a precious opportunity of action would, it is true, be lost to the Swedish army, of which the enemy would be sure to take the utmost advantage. It was, in short, in the power of the Emperor totally to ruin the Swedish interest in Germany, and to this he was actually invited by the prudent councils of the Duke of Friedland. Wallenstein advised him to proclaim a universal amnesty, and to meet the Protestant states with favourable conditions. In the first consternation produced by the fall of Gustavus Adolphus, such a declaration would have had the most powerful effects, and probably would have brought the wavering states back to their allegiance. But blinded by this unexpected turn of fortune, and infatuated by Spanish counsels, he anticipated a more brilliant issue from war, and, instead of listening to these propositions of an accommodation, he hastened to augment his forces. Spain, enriched by the grant of the tenth of the ecclesiastical possessions, which the pope confirmed, sent him considerable supplies, negociated for him at the Saxon court, and hastily levied troops for him in Italy to be employed in Germany. The Elector of Bavaria also considerably increased his military force; and the restless disposition of the Duke of Lorraine did not permit him to remain inactive in this favourable change of fortune. But while the enemy were thus busy to profit by the disaster of Sweden, Oxenstiern was diligent to avert its most fatal consequences.
