Wallenstein's whole character was expressed in these proposals, whether they were meant seriously or not. Cut off from German ideas by his Bohemian birth, he had no roots in Germany. The reverence which others felt for religious or political institutions had no echo in his mind. As he had been ready to overthrow princes and electors in the Emperor's name, so he was now ready to overthrow the Emperor in the name of the King of Sweden. Yet there was withal a greatness about him which raised him above such mere adventurers as Mansfeld. At the head of soldiers as uprooted as himself from all ties of home or nationality, he alone, amongst the leaders of the war, had embraced the two ideas which, if they had been welcomed by the statesmen of the Empire, would have saved Germany from intolerable evil. He wished for union and strength against foreign invasion, and he wished to found that union upon religious liberty. He would have kept out Gustavus if he could. But if that could not be done, he would join Gustavus in keeping out the French. [Sidenote: § 6. Impossibility of an understanding between Wallenstein and Gustavus.] Yet between Wallenstein and Gustavus it was impossible that there should be anything really in common. Wallenstein was large-minded because he was far removed from the ordinary prejudices of men. He was no more affected by their habits and thoughts than the course of a balloon is affected by the precipices and rivers below. Gustavus trod firmly upon his mother earth. His Swedish country, his Lutheran religion, his opposition to the House of Austria, were all very real to him. His greatness was the greatness which rules the world, the greatness of a man who, sharing the thoughts and feelings of men, rises above them just far enough to direct them, not too far to carry their sympathies with him. [Sidenote: § 7. Political plans of Gustavus.] Such a man was not likely to be content with mere military success. The vision of a soldier sovereignty to be shared with Wallenstein had no charms for him. If the Empire had fallen, it must be replaced not by an army but by fresh institutions; and those institutions, if they were to endure at all, must be based as far as possible on institutions already existing. Protestant Germany must be freed from oppression. It must be organized apart sufficiently for its own defence. Such an organization, the _Corpus Evangelicorum_, as he called it, like the North German Confederation of 1866, might or might not spread into a greater Germany of the future. It would need the support of Sweden and of France. It would not, indeed, satisfy Wallenstein's military ambition, or the more legitimate national longings of German patriots. But it had the advantage of being attainable if anything was attainable. It would form a certain bulwark against the aggression of the Catholic states without necessitating any violent change in the existing territorial institutions. [Sidenote: § 8. His military schemes.]
