It would be the easiest thing in the world for despotic Spain, so the Advocate thought, to reappear suddenly in force again at a moment's notice after the States' troops had been withdrawn and partially disbanded, and it would be difficult for the many-headed and many-tongued republic to act with similar promptness. To withdraw without a guarantee from Spain to the Treaty of Xanten, which had once been signed, sealed, and all but ratified, would be to give up fifty points in the game. Nothing but disaster could ensue. The Advocate as leader in all these negotiations and correspondence was ever actuated by the favourite quotation of William the Silent from Demosthenes, that the safest citadel against an invader and a tyrant is distrust. And he always distrusted in these dealings, for he was sure the Spanish cabinet was trying to make fools of the States, and there were many ready to assist it in the task. Now that one of the pretenders, temporary master of half the duchies, the Prince of Neuburg, had espoused both Catholicism and the sister of the Archbishop of Cologne and the Duke of Bavaria, it would be more safe than ever for Spain to make a temporary withdrawal. Maximilian of Bavaria was beyond all question the ablest and most determined leader of the Catholic party in Germany, and the most straightforward and sincere. No man before or since his epoch had, like him, been destined to refuse, and more than once refuse, the Imperial crown. Through his apostasy the Prince of Neuburg was in danger of losing his hereditary estates, his brothers endeavouring to dispossess him on the ground of the late duke's will, disinheriting any one of his heirs who should become a convert to Catholicism. He had accordingly implored aid from the King of Spain. Archduke Albert had urged Philip to render such assistance as a matter of justice, and the Emperor had naturally declared that the whole right as eldest son belonged, notwithstanding the will, to the Prince. With the young Neuburg accordingly under the able guidance of Maximilian, it was not likely that the grasp of the Spanish party upon these all-important territories would be really loosened. The Emperor still claimed the right to decide among the candidates and to hold the provinces under sequestration till the decision should be made--that was to say, until the Greek Kalends. The original attempt to do this through Archduke Leopold had been thwarted, as we have seen, by the prompt movements of Maurice sustained by the policy of Barneveld. The Advocate was resolved that the Emperor's name should not be mentioned either in the preamble or body of the treaty. And his course throughout the simulations, which were never negotiations, was perpetually baffled as much by the easiness and languor of his allies as the ingenuity of the enemy.
