The King, after the representations of the States, saw good ground to change his opinion and; becoming convinced that the Palatine had long been coquetting with the Austrian party, soon made no secret of his preference for Brandenburg. Subsequently Neuburg and Brandenburg fell into a violent quarrel notwithstanding an arrangement that the Palatine should marry the daughter of the Elector. In the heat of discussion Brandenburg on one occasion is said to have given his intended son-in-law a box on the ear! an argument 'ad hominem' which seems to have had the effect of sending the Palatine into the bosom of the ancient church and causing him to rely thenceforth upon the assistance of the League. Meantime, however, the Condominium settled by the Treaty of Dortmund continued in force; the third brother of Brandenburg and the eldest son of Neuburg sharing possession and authority at Dusseldorf until a final decision could be made.
A flock of diplomatists, professional or volunteers, openly accredited or secret, were now flying busily about through the troubled atmosphere, indicating the coming storm in which they revelled. The keen-sighted, subtle, but dangerously intriguing ambassador of the Republic, Francis Aerssens, had his hundred eyes at all the keyholes in Paris, that centre of ceaseless combination and conspiracy, and was besides in almost daily confidential intercourse with the King. Most patiently and minutely he kept the Advocate informed, almost from hour to hour, of every web that was spun, every conversation public or whispered in which important affairs were treated anywhere and by anybody. He was all-sufficient as a spy and intelligencer, although not entirely trustworthy as a counsellor. Still no man on the whole could scan the present or forecast the future more accurately than he was able to do from his advantageous position and his long experience of affairs.
There was much general jealousy between the States and the despotic king, who loved to be called the father of the Republic and to treat the Hollanders as his deeply obliged and very ungrateful and miserly little children. The India trade was a sore subject, Henry having throughout the negotiations sought to force or wheedle the States into renouncing that commerce at the command of Spain, because he wished to help himself to it afterwards, and being now in the habit of secretly receiving Isaac Le Maire and other Dutch leaders in that lucrative monopoly, who lay disguised in Paris and in the house of Zamet—but not concealed from Aerssens, who pledged himself to break, the neck of their enterprise—and were planning with the King a French East India Company in opposition to that of the Netherlands.
On the whole, however, despite these commercial intrigues which Barneveld through the aid of Aerssens was enabled to baffle, there was much cordiality and honest friendship between the two countries. Henry, far from concealing his political affection for the Republic, was desirous of receiving a special embassy of congratulation and gratitude from the States on conclusion of the truce; not being satisfied with the warm expressions of respect and attachment conveyed through the ordinary diplomatic channel.
"He wishes," wrote Aerssens to the Advocate, "a public demonstration—in order to show on a theatre to all Christendom the regard and deference of My Lords the States for his Majesty." The Ambassador suggested that Cornelis van der Myle, son-in-law of Barneveld, soon to be named first envoy for Holland to the Venetian republic, might be selected as chief of such special embassy.
"Without the instructions you gave me," wrote Aerssens, "Neuburg might have gained his cause in this court. Brandenburg is doing himself much injury by not soliciting the King."
"Much deference will be paid to your judgment," added the envoy, "if you see fit to send it to his Majesty."
Meantime, although the agent of Neuburg was busily dinning in Henry's ears the claims of the Palatine, and even urging old promises which, as he pretended, had been made, thanks to Barneveld, he took little by his importunity, notwithstanding that in the opinion both of Barneveld and Villeroy his claim 'stricti-juris' was the best. But it was policy and religious interests, not the strict letter of the law, that were likely to prevail. Henry, while loudly asserting that he would oppose any usurpation on the part of the Emperor or any one else against the Condominium, privately renewed to the States assurances of his intention to support ultimately the claims of Brandenburg, and notified them to hold the two regiments of French infantry, which by convention they still kept at his expense in their service, to be ready at a moment's warning for the great enterprise which he was already planning. "You would do well perhaps," wrote Aerssens to Barneveld, "to set forth the various interests in regard to this succession, and of the different relations of the claimants towards our commonwealth; but in such sort nevertheless and so dexterously that the King may be able to understand your desires, and on the other hand may see the respect you bear him in appearing to defer to his choice."
Neuburg, having always neglected the States and made advances to Archduke Albert, and being openly preferred over Brandenburg by the Austrians, who had however no intention of eventually tolerating either, could make but small headway at court, notwithstanding Henry's indignation that Brandenburg had not yet made the slightest demand upon him for assistance.
The Elector had keenly solicited the aid of the states, who were bound to him by ancient contract on this subject, but had manifested wonderful indifference or suspicion in regard to France. "These nonchalant Germans," said Henry on more than one occasion, "do nothing but sleep or drink."
