As might have been expected under these circumstances, the imperials made rapid progress. Ratisbon, the prize of Bernhard the year before, surrendered to the king of Hungary in July. Then Donauwörth was stormed, and siege was laid to Nördlingen. On September 2 the Cardinal-Infant came up with 15,000 men. The enemy watched the siege with a force far inferior in numbers. Bernhard was eager to put all to the test of battle. Horn recommended caution in vain. Against his better judgment he consented to fight. On September 6 the attack was made. By the end of the day Horn was a prisoner, and Bernhard was in full retreat, leaving 10,000 of his men dead upon the field, and 6,000 prisoners in the hands of the enemy, whilst the imperialists lost only 1,200 men.
§ 3. Important results from it.
Since the day of Breitenfeld, three years before, there had been no such battle fought as this of Nördlingen. As Breitenfeld had recovered the Protestant bishoprics of the north, Nördlingen recovered the Catholic bishoprics of the south. Bernhard's Duchy of Franconia disappeared in a moment under the blow. Before the spring of 1635 came, the whole of South Germany, with the exception of one or two fortified posts, was in the hands of the imperial commanders. The Cardinal-Infant was able to pursue his way to Brussels, with the assurance that he had done a good stroke of work on the way.
§ 4. French intervention.
The victories of mere force are never fruitful of good. As it had been after the successes of Tilly in 1622, and the successes of Wallenstein in 1626 and 1627, so it was now with the successes of the King of Hungary in 1634 and 1635. The imperialist armies had gained victories, and had taken cities. But the Emperor was none the nearer to the confidence of Germans. An alienated people, crushed by military force, served merely as a bait to tempt foreign aggression, and to make the way easy before it. After 1622, the King of Denmark had been called in. After 1627, an appeal was made to the King of Sweden. After 1634, Richelieu found his opportunity. The bonds between France and the mutilated League of Heilbronn were drawn more closely. German troops were to be taken into French pay, and the empty coffers of the League were filled with French livres. He who holds the purse holds the sceptre, and the princes of Southern and Western Germany, whether they wished it or not, were reduced to the position of satellites revolving round the central orb at Paris.
§ 5. The Peace of Prague.
Nowhere was the disgrace of submitting to French intervention felt so deeply as at Dresden. The battle of Nördlingen had cut short any hopes which John George might have entertained of obtaining that which Wallenstein would willingly have granted him. But, on the other hand, Ferdinand had learned something from experience. He would allow the Edict of Restitution to fall, though he was resolved not to make the sacrifice in so many words. But he refused to replace the Empire in the condition in which it had been before the war. The year 1627 was to be chosen as the starting point for the new arrangement. The greater part of the northern bishoprics would thus be saved to Protestantism. But Halberstadt would remain in the hands of a Catholic bishop, and the Palatinate would be lost to Protestantism for ever. Lusatia, which had been held in the hands of the Elector of Saxony for his expenses in the war of 1620, was to be ceded to him permanently, and Protestantism in Silesia was to be placed under the guarantee of the Emperor. Finally, Lutheranism alone was still reckoned as the privileged religion, so that Hesse Cassel and the other Calvinist states gained no security at all. On May 30, 1635, a treaty embodying these arrangements was signed at Prague by the representatives of the Emperor and the Elector of Saxony. It was intended not to be a separate treaty, but to be the starting point of a general pacification. Most of the princes and towns so accepted it, after more or less delay, and acknowledged the supremacy of the Emperor on its conditions. Yet it was not in the nature of things that it should put an end to the war. It was not an agreement which any one was likely to be enthusiastic about. The ties which bound Ferdinand to his Protestant subjects had been rudely broken, and the solemn promise to forget and forgive could not weld the nation into that unity of heart and spirit which was needed to resist the foreigner. A Protestant of the north might reasonably come to the conclusion that the price to be paid to the Swede and the Frenchman for the vindication of the rights of the southern Protestants was too high to make it prudent for him to continue the struggle against the Emperor. But it was hardly likely that he would be inclined to fight very vigorously for the Emperor on such terms.
§ 6. It fails in securing general acceptance.
If the treaty gave no great encouragement to anyone who was comprehended by it, it threw still further into the arms of the enemy those who were excepted from its benefits. The leading members of the League of Heilbronn were excepted from the general amnesty, though hopes of better treatment were held out to them if they made their submission. The Landgrave of Hesse Cassel was shut out as a Calvinist. Besides such as nourished legitimate grievances, there were others who, like Bernhard, were bent upon carving out a fortune for themselves, or who had so blended in their own minds consideration for the public good as to lose all sense of any distinction between the two.
§ 7. Degeneration of the war.
