When all was examined, the King's seal, and that of the ambassador, were put upon all the bureaux and the caskets which contained papers. The Abbe Dubois and Le Blanc went off together to give an account of their proceedings to the Regent, leaving a company of musketeers to guard the ambassador and his household.
I heard of the capture effected at Poitiers, at home, the morning after it occurred, without knowing anything of those arrested. As I was at table, a servant came to me from M. le Duc d'Orleans, summoning me to a council of the regency, at four o'clock that day. As it was not the usual day for the council, I asked what was the matter. The messenger was surprised at my ignorance and informed me that the Spanish ambassador was arrested. As soon as I had eaten a morsel, I quitted my company, and hastened to the Palais Royal, where I learnt from M. le Duc d'Orleans all that I have just related. Our conversation took up time, and, when it was over, I went away to the Tuileries. I found there astonishment painted upon several faces; little groups of two, three, and four people together; and the majority struck by the importance of the arrest, and little disposed to approve it.
M. le Duc d'Orleans arrived shortly after. He had, better than any man I have ever known, the gift of speech, and without needing any preparation he said exactly what he wanted to say, neither more nor less; his expressions were just and precise, a natural grace accompanied them with an air of proper dignity, always mixed with an air of politeness. He opened the council with a discourse upon the people and the papers seized at Poitiers, the latter proving that a very dangerous conspiracy against the state was on the eve of bursting, and of which the Ambassador of Spain was the principal promoter. His Royal Highness alleged the pressing reasons which had induced him to secure the person of this ambassador, to examine his papers, and to place them under guard. He showed that the protection afforded by the law of nations did not extend to conspiracies, that ambassadors rendered themselves unworthy of that protection when they took part in them, still more when they excited people against the state where they dwelt. He cited several examples of ambassadors arrested for less. He explained the orders he had given so as to inform all the foreign ministers in Paris of what had occurred, and had ordered Dubois to render an account to the council of what he had done at the ambassador's, and offered to read the letters from Cellamare to Cardinal Alberoni, found among the papers brought from Poitiers.
The Abbe Dubois stammered out a short and ill-arranged recital of what he had done at the ambassador's house, and dwelt upon the importance of the discovery and upon that of the conspiracy as far as already known. The two letters he read left me no doubt that Cellamare was at the head of this affair, and that Alberoni had entered into it as far as he. We were much scandalised with the expressions in these letters against M. le Duc d'Orleans, who was in no way spared.
This prince spoke again, to say he did not suspect the King or Queen of Spain to be mixed up in this affair, but that he attributed it all to the passion of Alberoni, and that of his ambassador to please him, and that he would ask for justice from their Catholic Majesties. He showed the importance of neglecting no means in order to clear up an affair so capital to the repose and tranquillity of the kingdom, and finished by saying, that until he knew more he would name nobody who was mixed up in the matter. All this speech was much applauded, and I believe there were some among the company who felt greatly relieved when they heard the Regent say he would name nobody nor would he allow suspicions to be circulated until all was unravelled.
Nevertheless the next day, Saturday, the 10th of December, more than one arrest was made. Others took place a few days afterwards.
On Tuesday, the 13th of December, all the foreign ministers went to the Palais Royal, according to custom; not one made any complaint of what had happened. A copy of the two letters read at the council was given to them. In the afternoon, Cellamare was placed in a coach with a captain of cavalry and a captain of dragoons, chosen to conduct him: to Blois, until Saint-Aignan, our ambassador in Spain, should arrive in France.
The position of our ambassador, Saint-Aignan, at Madrid, was, as may be imagined, by no means agreeable. The two courts were just upon the point of an open rupture, thanks to the hatred Alberoni had made it a principle to keep up in Spain against M. le Duc d'Orleans, by crying down his actions, his government, his personal conduct, his most innocent acts, and by rendering suspicious even his favourable proceedings with regard to Spain. Alberoni for a long time had ceased to keep on even decent terms with Saint-Aignan, scandalising thus even the most unfavourably disposed towards France. Saint-Aignan only maintained his position by the sagacity of his conduct, and he was delighted when he received orders to return to France. He asked for his parting audience, and meanwhile bade adieu to all his friends and to all the Court. Alberoni, who every moment expected decisive news from Cellamare respecting the conspiracy, wished to remain master of our ambassador, so as, in case of accident, to have a useful hostage in his hands as security for his own ambassador. He put off therefore this parting audience under various pretexts. At last, Saint-Aignan, pressed by his reiterated orders (orders all the more positive because suspicion had already begun to foresee a disturbance ever alarming), spoke firmly to the Cardinal, and declared that if this audience were not at once accorded to him, he would do without it! Therefore the Cardinal, in anger, replied with a menace, that he knew well enough how to hinder, him, from acting thus.
Saint-Aignan wisely contained himself; but seeing to what sort of a man he was exposed, and judging rightly why he was detained at Madrid, took his measures so secretly and so well, that he set out the same night, with his most necessary equipage, gained ground and arrived at the foot of the Pyrenees without being overtaken and arrested; two occurrences which he expected at every moment, knowing that Alberoni was a man who would stick at nothing.
Saint-Aignan, already so far advanced, did not deem it advisable to expose himself any longer, bothered as he would be among the mountains by his carriages. He and the Duchess, his wife, followed by a waiting-woman and three valets, with a very trusty guide, mounted upon mules and rode straight for Saint-Jean-Pied-de-Port without stopping a moment more on the road than was necessary. He sent on his equipages to Pampeluna at a gentle pace, and placed in his carriage an intelligent valet de chambre and a waiting-woman, with orders to pass themselves off as the ambassador and ambassadress of France, and in case they were arrested to cry out a good deal. The arrest did not fail to happen. The people despatched by Alberoni soon came up with the carriage. The pretended ambassador and ambassadress played their parts very well, and they who had arrested them did not doubt for a moment they had made a fine capture, sending news of it to Madrid, and keeping the prisoners in Pampeluna, to which the party returned.
