One of them, Madame Louise, who was deeply pious, left him to enter the convent of the Carmelites; he often went to see her, and granted her all the favors she asked.

But by this time Madame Dubarry had become all- powerful; to secure to her the honors of presentation at court, the king personally solicited the ladies with whom he was intimate in order to get them to support his favorite on this new stage; when the youthful Marie Antoinette, Archduchess of Austria, and daughter of Maria Theresa, whose marriage the Duke of Choiseul had negotiated, arrived in France, in 1770, to espouse the dauphin, Madame Dubarry appeared alone with the royal family at the banquet given at La Muette on the occasion of the marriage.
After each reaction of religious fright and transitory repentance, after each warning from God that snatched him for an instant from the depravity of his life, the king plunged more deeply than before into shame.

Madame Dubarry was to reign as much as Louis XV.
Before his fall the Duke of Choiseul had made a last effort to revive abroad that fortune of France which he saw sinking at home without his being able to apply any effective remedy.

He had vainly attempted to give colonies once more to France by founding in French Guiana settlements which had been unsuccessfully attempted by a Rouennese Company as early as 1634.

The enterprise was badly managed; the numerous colonists, of very diverse origin and worth, were cast without resources upon a territory as unhealthy as fertile.
