Finding that Du Vair, to whom the Seals had been restored after the dismissal of Mangot, was in the habit of taking his seat at the Council above all the nobles, even when the Chancellor was present, although the Keeper of the Seals was not an officer of the Crown, his gorge rose at once, and he went to the King to protest against so intolerable an affront to his own dignity and that of his order. Du Vair happened to be with the King, and, says Bassompierre, “as M. d’Épernon was a little violent, he attacked the Keeper of the Seals, who answered him more sharply than he should have done.” Three days later, Louis XIII summoned the duke and Du Vair to his cabinet, and, in the presence of Bassompierre and several other courtiers, ordered them to be reconciled. By way of answer, d’Épernon shrugged his shoulders, upon which the young monarch, who was seated, rose in great indignation, and severely reprimanded him. Then, observing that he had affairs of importance to attend to, he abruptly quitted the room. D’Épernon retired, followed by Bassompierre, but, to their astonishment, they found all the doors of the ante-chamber closed and locked. It looked “as though the King intended to have the duke arrested, and had given orders for the doors to be secured, in order to allow time for an officer of the Guards to be summoned.” However, it occurred to Bassompierre that perhaps the door leading to the King’s private staircase, which was opposite that of his chamber, might not be locked, and, finding it unfastened, he fetched d’Épernon, and they descended the stairs and made their way to the Salle Haute, where the old noble’s attendants were awaiting him. As d’Épernon was leaving the Louvre, he asked his friend “to send him warning if anything had been resolved against him.” Bassompierre accordingly spoke to Luynes on the subject, and was informed that, as M. d’Épernon intended going to his government of Metz, he would be well advised to hasten his departure, since there were persons who might incite the King against him. Bassompierre, of course, understood very well who it was who was likely to incite the King.
