In 1670 the King wished to make a triumphant journey with the ladies, under pretext of visiting his possessions in Flanders, accompanied by an army, and by all his household troops, so that the alarm was great in the Low Countries, which he took no pains to appease. He gave the command of all to Lauzun, with the patent of army-general. Lauzun performed the duties of his post with much intelligence, and with extreme gallantry and magnificence. This brilliancy, and this distinguished mark of favour, made Louvois, whom Lauzun in no way spared, think very seriously. He united with Madame de Montespan (who had not pardoned the discovery Lauzun had made, or the atrocious insults he had bestowed upon her), and the two worked so well that they reawakened in the King's mind recollections of the broken sword, the refusal in the Bastille of the post of captain of the guards, and made his Majesty look upon Lauzun as a man who no longer knew himself, who had suborned Mademoiselle until he had been within an inch of marrying her, and of assuring to himself immense wealth; finally, as a man, very dangerous on account of his audacity, and who had taken it into his head to gain the devotion of the troops by his magnificence, his services to the officers, and by the manner in which he had treated them during the Flanders journey, making himself adored. They made him out criminal for having remained the friend of, and on terms of great intimacy with, the Comtesse de Soissons, driven from the Court and suspected of crimes. They must have accused Lauzun also of crimes which I have never heard of, in order to procure for him the barbarous treatment they succeeded in subjecting him to. Their intrigues lasted all the year, 1671, without Lauzun discovering anything by the visage of the King, or that of Madame de Montespan. Both the King and his mistress treated him with their ordinary distinction and familiarity. He was a good judge of jewels (knowing also how to set them well), and Madame de Montespan often employed him in this capacity. One evening, in the middle of November, 1671, he arrived from Paris, where Madame de Montespan had sent him in the morning for some precious stones, and as he was about to enter his chamber he was arrested by the Marechal de Rochefort, captain of the guards. Lauzun, in the utmost surprise, wished to know why, to see the King or Madame de Montespan--at least, to write to them; everything was refused him. He was taken to the Bastille, and shortly afterwards to Pignerol, where he was shut up in a low-roofed dungeon. His post of captain of the body-guard was given to M. de Luxembourg, and the government of Berry to the Duc de la Rochefoucauld, who, at the death of Guitz, at the passage of the Rhine, 12th June, 1672, was made grand master of the wardrobe.
