The monarch and his ancient favourite had agreed between them to sell to Mademoiselle the freedom of the man she loved so deeply. What was to be the price? This was not yet disclosed. It was some time before Mademoiselle comprehended, and then she was so disconcerted that she said nothing. She felt that the combat was not an equal one between herself, from whom passion had taken away all judgment, and Mme. de Montespan, who was perfectly calm, and she hesitated, fearing some snare: "Finally, I resolved to make M. de Maine my heir, provided that the King would send for Lauzun and consent that I should marry him." Some third person brought these conditions to Mme. de Montespan and was received with open arms. Louis XIV. thanked his cousin graciously without making any allusion to the condition; he could always assert that he had made no promise.

Mademoiselle wished that he would at least give her some news of Lauzun. Mme. de Montespan responded to her insistence: "It is necessary to have patience," and affairs remained at this point.

At the end of some weeks, Mademoiselle perceived that she was no longer free. She had counted upon taking her time and having sureties before proceeding further. An immediate execution of the deed of gift was insisted upon, and she was so harassed that she no longer felt at liberty to breathe freely.

"The King must not be played with," declared Mme. de Montespan; "when a promise is made it must be kept." "But," objected Mademoiselle, "I wish the freedom of M. de Lauzun, and suppose that after what I have done I should find myself deceived, and my friend should not be liberated?" Louvois was then sent to frighten her, or Colbert in order to compass some concession. It was no longer a matter of testament.

A donation while living[297] was exacted, of the Principality of Dombes and of the Comté of Eu without reference to the rest, and this assignment was obtained, in spite of complaints and the bitterest tears; "for they were demanding precisely what had been given to Lauzun, and Mademoiselle could not without difficulty resolve to despoil her lover." She finally comprehended that the King would not cease persecuting her until she consented, and, feeling no hope of diminishing the demands,[298] she yielded.

The gift to the Duc de Maine was signed February 2, 1681. It gave some agreeable days to Mademoiselle. The King assured her of his gratitude. "At supper he regarded me pleasantly and conversed with me; this was most charming." Nevertheless, Lauzun did not appear. One day Mme. de Montespan informed the Princess that the King would never permit Lauzun to be Duc de Montpensier, and that it would be necessary to have a secret marriage. The Princess cried out: "What! Madame, I am to permit him to live with me as my husband with no marriage ceremony! Of what will the world think me capable?"

This passage in the Mémoires apparently fixes the date of marriage after the return of Lauzun from his captivity. There exist, however, a number of moral proofs against this later date.

Some time after this conversation, in the beginning of April, 1681, the Court being at Saint-Germain, Mme. de Montespan announced to Mademoiselle the immediate departure of Lauzun for the Baths of Bourbon, and she then drew her, slightly against her will, to the end of the terrace, far from indiscreet ears. "When we were in the Val, which is a garden at the end of the Park of Saint-Germain, she said to me, 'The King has asked me to tell you that he does not wish you to dream of ever marrying M. de Lauzun, at least, officially.'"

Mademoiselle had been tricked.

"Upon this, I began to weep and to talk about the gifts I had made, only on the one condition. Mme. de Montespan said, 'I have promised nothing.' She had gained what she wished, and was willing enough to bear anything I might say." In the evening it was necessary to assume a delighted air and thank the King for Lauzun's freedom; a single sign of ill-humour and Mademoiselle ran the risk of receiving nothing in exchange for her millions.
