He hoped that the Prince would be arrested at Breda and sent back by the States. Villeroy said that if it was not done, they would be guilty of black ingratitude. It would be an awkward undertaking, however, and the States devoutly prayed that they might not be put to the test. The crafty Aerssens suggested to Barneveld that if Conde was not within their territory it would be well to assure the King that, had he been there, he would have been delivered up at once. "By this means," said the Ambassador, "you will give no cause of offence to the Prince, and will at the same time satisfy the King. It is important that he should think that you depend immediately upon him. If you see that after his arrest they take severe measures against him, you will have a thousand ways of parrying the blame which posterity might throw upon you. History teaches you plenty of them."
He added that neither Sully nor anyone else thought much of the Poitou conspiracy. Those implicated asserted that they had intended to raise troops there to assist the King in the Cleve expedition. Some people said that Henry had invented this plot against his throne and life. The Ambassador, in a spirit of prophecy, quoted the saying of Domitian: "Misera conditio imperantium quibus de conspiratione non creditor nisi occisis."
Meantime the fugitives continued their journey. The Prince was accompanied by one of his dependants, a rude officer, de Rochefort, who carried the Princess on a pillion behind him. She had with her a lady- in-waiting named du Certeau and a lady's maid named Philippote. She had no clothes but those on her back, not even a change of linen. Thus the young and delicate lady made the wintry journey through the forests. They crossed the frontier at Landrecies, then in the Spanish Netherlands, intending to traverse the Archduke's territory in order to reach Breda, where Conde meant to leave his wife in charge of his sister, the Princess of Orange, and then to proceed to Brussels.
He wrote from the little inn at Landrecies to notify the Archduke of his project. He was subsequently informed that Albert would not prevent his passing through his territories, but should object to his making a fixed residence within them. The Prince also wrote subsequently to the King of Spain and to the King of France.
To Henry he expressed his great regret at being obliged to leave the kingdom in order to save his honour and his life, but that he had no intention of being anything else than his very humble and faithful cousin, subject, and servant. He would do nothing against his service, he said, unless forced thereto, and he begged the King not to take it amiss if he refused to receive letters from any one whomsoever at court, saving only such letters as his Majesty himself might honour him by writing.
The result of this communication to the King was of course to enrage that monarch to the utmost, and his first impulse on finding that the Prince was out of his reach was to march to Brussels at once and take possession of him and the Princess by main force. More moderate counsels prevailed for the moment however, and negotiations were attempted.
Praslin did not contrive to intercept the fugitives, but the States- General, under the advice of Barneveld, absolutely forbade their coming to Breda or entering any part of their jurisdiction. The result of Conde's application to the King of Spain was an ultimate offer of assistance and asylum, through a special emissary, one Anover; for the politicians of Madrid were astute enough to see what a card the Prince might prove in their hands.
Henry instructed his ambassador in Spain to use strong and threatening language in regard to the harbouring a rebel and a conspirator against the throne of France; while on the other hand he expressed his satisfaction with the States for having prohibited the Prince from entering their territory. He would have preferred, he said, if they had allowed him entrance and forbidden his departure, but on the whole he was content. It was thought in Paris that the Netherland government had acted with much adroitness in thus abstaining both from a violation of the law of nations and from giving offence to the King.
A valet of Conde was taken with some papers of the Prince about him, which proved a determination on his part never to return to France during the lifetime of Henry. They made no statement of the cause of his flight, except to intimate that it might be left to the judgment of every one, as it was unfortunately but too well known to all.
Refused entrance into the Dutch territory, the Prince was obliged to renounce his project in regard to Breda, and brought his wife to Brussels. He gave Bentivoglio, the Papal nuncio, two letters to forward to Italy, one to the Pope, the other to his nephew, Cardinal Borghese. Encouraged by the advices which he had received from Spain, he justified his flight from France both by the danger to his honour and to his life, recommending both to the protection of his Holiness and his Eminence. Bentivoglio sent the letters, but while admitting the invincible reasons for his departure growing out of the King's pursuit of the Princess, he refused all credence to the pretended violence against Conde himself. Conde informed de Praslin that he would not consent to return to France. Subsequently he imposed as conditions of return that the King should assign to him certain cities and strongholds in Guienne, of which province he was governor, far from Paris and very near the Spanish frontier; a measure dictated by Spain and which inflamed Henry's wrath almost to madness. The King insisted on his instant return, placing himself and of course the Princess entirely in his hands and receiving a full pardon for this effort to save his honour. The Prince and Princess of Orange came from Breda to Brussels to visit their brother and his wife. Here they established them in the Palace of Nassau, once the residence in his brilliant youth of William the Silent; a magnificent mansion, surrounded by park and garden, built on the brow of the almost precipitous hill, beneath which is spread out so picturesquely the antique and beautiful capital of Brabant.
