The conferences were however for a season interrupted, and a new aspect was given to affairs by an unforeseen and terrible event.
Meanwhile it is necessary to glance for a moment at the doings of the special embassy to France, the instructions for which were prepared by Barneveld almost at the same moment at which he furnished those for the commission to England.
The ambassadors were Walraven, Seignior of Brederode, Cornelis van der Myle, son-in-law of the Advocate, and Jacob van Maldere. Remembering how impatient the King of France had long been for their coming, and that all the preparations and decisions for a great war were kept in suspense until the final secret conferences could be held with the representatives of the States-General, it seems strange enough to us to observe the extreme deliberation with which great affairs of state were then conducted and the vast amount of time consumed in movements and communications which modern science has either annihilated or abridged from days to hours. While Henry was chafing with anxiety in Paris, the ambassadors, having received Barneveld's instructions dated 31st March, set forth on the 8th April from the Hague, reached Rotterdam at noon, and slept at Dordrecht. Newt day they went to Breda, where the Prince of Orange insisted upon their passing a couple of days with him in his castle, Easter-day being 11th April. He then provided them with a couple of coaches and pair in which they set forth on their journey, going by way of Antwerp, Ghent, Courtray, Ryssel, to Arras, making easy stages, stopping in the middle of the day to bait, and sleeping at each of the cities thus mentioned, where they duly received the congratulatory visit and hospitalities of their respective magistracies.
While all this time had been leisurely employed in the Netherlands in preparing, instructing, and despatching the commissioners, affairs were reaching a feverish crisis in France.
The States' ambassador resident thought that it would have been better not to take such public offence at the retreat of the Prince of Conde. The King had enough of life and vigour in him; he could afford to leave the Dauphin to grow up, and when he should one day be established on the throne, he would be able to maintain his heritage. "But," said Aerssens, "I fear that our trouble is not where we say it is, and we don't dare to say where it is." Writing to Carew, former English ambassador in Paris, whom we have just seen in attendance on the States' commissioners in London, he said: "People think that the Princess is wearying herself much under the protection of the Infanta, and very impatient at not obtaining the dissolution of her marriage, which the Duchess of Angouleme is to go to Brussels to facilitate. This is not our business, but I mention it only as the continuation of the Tragedy which you saw begin. Nevertheless I don't know if the greater part of our deliberations is not founded on this matter."
It had been decided to cause the Queen to be solemnly crowned after Easter. She had set her heart with singular persistency upon the ceremony, and it was thought that so public a sacrament would annihilate all the wild projects attributed to Spain through the instrumentality of Conde to cast doubts on the validity of her marriage and the legitimacy of the Dauphin. The King from the first felt and expressed a singular repugnance, a boding apprehension in regard to the coronation, but had almost yielded to the Queen's importunity. He told her he would give his consent provided she sent Concini to Brussels to invite in her own name the Princess of Conde to be present on the occasion. Otherwise he declared that at least the festival should be postponed till September.
The Marquis de Coeuvres remained in disgrace after the failure of his mission, Henry believing that like all the world he had fallen in love with the Princess, and had only sought to recommend himself, not to further the suit of his sovereign.
Meanwhile Henry had instructed his ambassador in Spain, M. de Vaucelas, to tell the King that his reception of Conde within his dominions would be considered an infraction of the treaty of Vervins and a direct act of hostility. The Duke of Lerma answered with a sneer that the Most Christian King had too greatly obliged his Most Catholic Majesty by sustaining his subjects in their rebellion and by aiding them to make their truce to hope now that Conde would be sent back. France had ever been the receptacle of Spanish traitors and rebels from Antonio Perez down, and the King of Spain would always protect wronged and oppressed princes like Conde. France had just been breaking up the friendly relations between Savoy and Spain and goading the Duke into hostilities.
On the other hand the King had more than one stormy interview with Don Inigo de Cardenas in Paris. That ambassador declared that his master would never abandon his only sister the most serene Infanta, such was the affection he born her, whose dominions were obviously threatened by these French armies about to move to the frontiers. Henry replied that the friends for whom he was arming had great need of his assistance; that his Catholic Majesty was quite right to love his sister, whom he also loved; but that he did not choose that his own relatives should be so much beloved in Spain as they were. "What relatives?" asked Don Inigo. "The Prince of Conde," replied the King, in a rage, "who has been debauched by the Spaniards just as Marshal Biron was, and the Marchioness Verneuil, and so many others. There are none left for them to debauch now but the Dauphin and his brothers." The Ambassador replied that, if the King had consulted him about the affair of Conde, he could have devised a happy issue from it. Henry rejoined that he had sent messages on the subject to his Catholic Majesty, who had not deigned a response, but that the Duke of Lerma had given a very indiscreet one to his ambassador. Don Inigo professed ignorance of any such reply. The King said it was a mockery to affect ignorance of such matters. Thereupon both grew excited and very violent in their discourses; the more so as Henry knowing but little Spanish and the Envoy less French they could only understand from tone and gesture that each was using exceedingly unpleasant language. At last Don Inigo asked what he should write to his sovereign. "Whatever you like," replied the King, and so the audience terminated, each remaining in a towering passion.
Subsequently Villeroy assured the Archduke's ambassador that the King considered the reception given to the Prince in the Spanish dominions as one of the greatest insults and injuries that could be done to him. Nothing could excuse it, said the Secretary of State, and for this reason it was very difficult for the two kings to remain at peace with each other, and that it would be wiser to prevent at once the evil designs of his Catholic Majesty than to leave leisure for the plans to be put into execution, and the claims of the Dauphin to his father's crown to be disputed at a convenient season.
