After a short campaign, and thanks to Rosny's ordnance, he obtained what he desired, and by a treaty of January 17, 1601, he added to French territory La Bresse, Le Bugey, the district of Gex, and the citadel of Bourg, which still held out after the capture of the town.

He was more and more dear to France, to which he had restored peace at home as well as abroad, and industrial, commercial, financial, monumental, and scientific prosperity, until lately unknown.
Sully covered the country with roads, bridges, canals, buildings, and works of public utility.

The moment the king, after the annulment of his marriage with Marguerite de Valois, saw his new wife, Mary de' Medici, at Lyons, she had disgusted him, and she disgusted him more every day by her cantankerous and headstrong temper; but on the 27th of September, 1601, she brought him a son, who was to be Louis XIII.

Henry used to go for distraction from his wife's temper to his favorite, Henriette d'Entraigues, who knew how to please him at the same time that she was haughty and exacting towards him.

He set less store upon the peace of his household than upon that of his kingdom; he had established his favorite at the Louvre itself, close beside his wife; and, his new marriage once contracted, he considered his domestic life settled, as well as his political position.
He was mistaken on both points; he was not at the end of either his political dangers or his amorous fancies.
