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.

Could this political seer have cast his horoscope of the Thirty Years' War at this hour of its nativity for the instruction of such men as Walsingham or Burleigh, Henry of Navarre or Sully, Richelieu or Gustavus Adolphus, would the course of events have been modified? These very idlest of questions are precisely those which inevitably occur as one ponders the seeming barrenness of an epoch in reality so pregnant.

"One would think," said Barneveld, comparing what was then the future with the real past, "that these plans in Prague against the Elector-Palatine are too gross for belief; but when I reflect on the intense bitterness of these people, when I remember what was done within living men's memory to the good elector Hans Frederic of Saxony for exactly the same reasons, to wit, hatred of our religion, and determination to establish Imperial authority, I have great apprehension. I believe that the Roman League will use the present occasion to carry out her great design; holding France incapable of opposition to her, Germany in too great division, and imagining to themselves that neither the King of Great Britain nor these States are willing or able to offer effectual and forcible resistance. Yet his Majesty of Great Britain ought to be able to imagine how greatly the religious matter in general concerns himself and the electoral house of the Palatine, as principal heads of the religion, and that these vast designs should be resisted betimes, and with all possible means and might. My Lords the States have good will, but not sufficient strength, to oppose these great forces single-handed. One must not believe that without great and prompt assistance in force from his Majesty and other fellow religionists My Lords the States can undertake so vast an affair. Do your uttermost duty there, in order that, ere it be too late, this matter be taken to heart by his Majesty, and that his authority and credit be earnestly used with other kings, electors, princes, and republics, that they do likewise. The promptest energy, good will, and affection may be reckoned on from us."
