The king, by the advice of his renowned minister of war, Marshal Louvois, placed strong garrisons in the cities he had captured, while the celebrated engineer, M. Vauban, was intrusted with enlarging and strengthening the fortifications. From this victorious campaign Louis XIV. returned to Paris, receiving adulation from the courtiers as if he were more than mortal. Madame de Montespan accompanied the court on this military pleasure tour. She availed herself of every opportunity to attract the attention of the king and ingratiate herself in his favor. She so far succeeded in exciting the jealousy of the queen against Madame de la Valliere, upon whom she was at the same time lavishing her most tender caresses, that her majesty treated the sensitive and desponding favorite with such rudeness that, with a crushed spirit, she decided to leave the court and retire to Versailles, there to await the conclusion of the campaign.

His heart was wounded and his suspicions aroused. At last he was apprised of her manifest endeavors to attract the attention of the king. He wrote severely; informed her of the extent of his knowledge. He threatened to expose her conduct to her own family, and to shut her up in a convent. At the same time, he commanded her to send to him, by the messenger who bore his letter, their little son, that he might not be contaminated by association with so unworthy a mother. It was too late. The marchioness was involved in such guilty relations with the king that she could not easily be extricated. Still she was much alarmed by the angry letter of her husband. The king perceived her anxiety, and inquired the cause. She placed the letter in his hands. He read it, changing color as he read. He then coolly remarked,
