The courtyard of the Nassau Palace was filled with cavalry sent by the Archduke, while five hundred burgher guards sent by the magistrates were drawn up around the gate. The noise and uproar, gaining at every moment more mysterious meaning by the darkness of night, soon spread through the city. The whole population was awake, and swarming through the streets. Such a tumult had not for years been witnessed in Brussels, and the rumour flew about and was generally believed that the King of France at the head of an army was at the gates of the city determined to carry off the Princess by force. But although the superfluous and very scandalous explosion might have been prevented, there could be no doubt that the stratagem had been defeated.
Nevertheless, the effrontery and ingenuity of de Coeuvres became now sublime. Accompanied by his colleague, the resident minister, de Berny, who was sure not to betray the secret because he had never known it—his wife alone having been in the confidence of the Princess—he proceeded straightway to the Archduke's palace, and, late in the night as it was, insisted on an audience.
Here putting on his boldest face when admitted to the presence, he complained loudly of the plot, of which he had just become aware, contrived by the Prince of Conde to carry off his wife to Spain against her will, by main force, and by assistance of Flemish nobles, archiducal body-guard, and burgher militia.
It was all a plot of Conde, he said, to palliate still more his flight from France. Every one knew that the Princess could not fly back to Paris through the air. To take her out of a house filled with people, to pierce or scale the walls of the city, to arrange her journey by ordinary means, and to protect the whole route by stations of cavalry, reaching from Brussels to the frontier, and to do all this in profound secrecy, was equally impossible. Such a scheme had never been arranged nor even imagined, he said. The true plotter was Conde, aided by ministers in Flanders hostile to France, and as the honour of the King and the reputation of the Princess had been injured by this scandal, the Ambassador loudly demanded a thorough investigation of the affair in order that vengeance might fall where it was due.
The prudent Albert was equal to the occasion. Not wishing to state the full knowledge which he possessed of de Coeuvres' agency and the King's complicity in the scheme of abduction to France, he reasoned calmly with the excited marquis, while his colleague looked and listened in dumb amazement, having previously been more vociferous and infinitely more sincere than his colleague in expressions of indignation.
The Archduke said that he had not thought the plot imputed to the King and his ambassador very probable. Nevertheless, the assertions of the Prince had been so positive as to make it impossible to refuse the guards requested by him. He trusted, however, that the truth would soon be known, and that it would leave no stain on the Princess, nor give any offence to the King.
Surprised and indignant at the turn given to the adventure by the French envoys, he nevertheless took care to conceal these sentiments, to abstain from accusation, and calmly to inform them that the Princess next morning would be established under his own roof; and enjoy the protection of the Archduchess.
For it had been arranged several days before that Margaret should leave the palace of Nassau for that of Albert and Isabella on the 14th, and the abduction had been fixed for the night of the 13th precisely because the conspirators wished to profit by the confusion incident on a change of domicile.
The irrepressible de Coeuvres, even then hardly willing to give up the whole stratagem as lost, was at least determined to discover how and by whom the plot had been revealed. In a cemetery piled three feet deep with snow on the evening following that mid-winter's night which had been fixed for the Princess's flight, the unfortunate ambassador waited until a certain Vallobre, a gentleman of Spinola's, who was the go-between of the enamoured Genoese and the Princess, but whom de Coeuvres had gained over, came at last to meet him by appointment. When he arrived, it was only to inform him of the manner in which he had been baffled, to convince him that the game was up, and that nothing was left him but to retreat utterly foiled in his attempt, and to be stigmatized as a blockhead by his enraged sovereign.
Next day the Princess removed her residence to the palace of the Archdukes, where she was treated with distinguished honour by Isabella, and installed ceremoniously in the most stately, the most virtuous, and the most dismal of courts. Her father and aunt professed themselves as highly pleased with the result, and Pecquius wrote that "they were glad to know her safe from the importunities of the old fop who seemed as mad as if he had been stung by a tarantula."
