So long as it was possible for the States to retain their hold on both the claimants, the Advocate, pursuant to his uniform policy of moderation, was not disposed to help throw the Palatine into the hands of the Spanish party. He was well aware, however, that Neuburg by his marriage and his conversion was inevitably to become the instrument of the League and to be made use of in the duchies at its pleasure, and that he especially would be the first to submit with docility to the decree of the Emperor. The right to issue such decree the States under guidance of Barneveld were resolved to resist at all hazards.
"Work diligently, nevertheless," said he, "that they permit nothing there directly or indirectly that may tend to the furtherance of the League, as too prejudicial to us and to all our fellow religionists. Tell them too that the late king, the King of Great Britain, the united electors and princes of Germany, and ourselves, have always been resolutely opposed to making the dispute about the succession in the duchies depend on the will of the Emperor and his court. All our movements in the year 1610 against the attempted sequestration under Leopold were to carry out that purpose. Hold it for certain that our present proceedings for strengthening and maintaining the city and fortress of Julich are considered serviceable and indispensable by the British king and the German electors and princes. Use your best efforts to induce the French government to pursue the same policy—if it be not possible openly, then at least secretly. My conviction is that, unless the Prince-Palatine is supported by, and his whole designs founded upon, the general league against all our brethren of the religion, affairs may be appeased."
The Envoy was likewise instructed to do his best to further the matrimonial alliance which had begun to be discussed between the Prince of Wales and the second daughter of France. Had it been possible at that moment to bring the insane dream of James for a Spanish alliance to naught, the States would have breathed more freely. He was also to urge payment of the money for the French regiments, always in arrears since Henry's death and Sully's dismissal, and always supplied by the exchequer of Holland. He was informed that the Republic had been sending some war ships to the Levant, to watch the armada recently sent thither by Spain, and other armed vessels into the Baltic, to pursue the corsairs with whom every sea was infested. In one year alone he estimated the loss to Dutch merchants by these pirates at 800,000 florins. "We have just captured two of the rovers, but the rascally scum is increasing," he said.
Again alluding to the resistance to be made by the States to the Imperial pretensions, he observed, "The Emperor is about sending us a herald in the Julich matter, but we know how to stand up to him."
And notwithstanding the bare possibility which he had admitted, that the Prince of Neuburg might not yet have wholly sold himself, body and soul, to the Papists, he gave warning a day or two afterwards in France that all should be prepared for the worst.
"The Archdukes and the Prince of Neuburg appear to be taking the war earnestly in hand," he said. "We believe that the Papistical League is about to make a great effort against all the co-religionists. We are watching closely their movements. Aachen is first threatened, and the Elector-Palatine likewise. France surely, for reasons of state, cannot permit that they should be attacked. She did, and helped us to do, too much in the Julich campaign to suffer the Spaniards to make themselves masters there now."
It has been seen that the part played by France in the memorable campaign of 1610 was that of admiring auxiliary to the States' forces; Marshal de la Chatre having in all things admitted the superiority of their army and the magnificent generalship of Prince Maurice. But the government of the Dowager had been committed by that enterprise to carry out the life-long policy of Henry, and to maintain his firm alliance with the Republic. Whether any of the great king's acuteness and vigour in countermining and shattering the plans of the House of Austria was left in the French court, time was to show. Meantime Barneveld was crying himself hoarse with warnings into the dull ears of England and France.
A few weeks later the Prince of Neuburg had thrown off the mask. Twelve thousand foot and 1500 horse had been raised in great haste, so the Advocate informed the French court, by Spain and the Archdukes, for the use of that pretender. Five or six thousand Spaniards were coming by sea to Flanders, and as many Italians were crossing the mountains, besides a great number mustering for the same purpose in Germany and Lorraine. Barneveld was constantly receiving most important intelligence of military plans and movements from Prague, which he placed daily before the eyes of governments wilfully blind.
"I ponder well at this crisis," he said to his friend Caron, "the intelligence I received some months back from Ratisbon, out of the cabinet of the Jesuits, that the design of the Catholic or Roman League is to bring this year a great army into the field, in order to make Neuburg, who was even then said to be of the Roman profession and League, master of Julich and the duchies; to execute the Imperial decree against Aachen and Mulheim, preventing any aid from being sent into Germany by these Provinces, or by Great Britain, and placing the Archduke and Marquis Spinola in command of the forces; to put another army on the frontiers of Austria, in order to prevent any succour coming from Hungary, Bohemia, Austria, Moravia, and Silesia into Germany; to keep all these disputed territories in subjection and devotion to the Emperor, and to place the general conduct of all these affairs in the hands of Archduke Leopold and other princes of the House of Austria. A third army is to be brought into the Upper Palatinate, under command of the Duke of Bavaria and others of the League, destined to thoroughly carry out its designs against the Elector-Palatine, and the other electors, princes, and estates belonging to the religion."
This intelligence, plucked by Barneveld out of the cabinet of the Jesuits, had been duly communicated by him months before to those whom it most concerned, and as usual it seemed to deepen the lethargy of the destined victims and their friends. Not only the whole Spanish campaign of the present year had thus been duly mapped out by the Advocate, long before it occurred, but this long buried and forgotten correspondence of the statesman seems rather like a chronicle of transactions already past, so closely did the actual record, which posterity came to know too well, resemble that which he saw, and was destined only to see, in prophetic vision.
