At length the period arrived in which Madame de Verneuil was about to enforce her claim upon the tenderness of her royal lover, and already he spoke of returning for a while to Monceaux; when a violent storm, and the falling of a thunderbolt in the very chamber of the invalid, so affected her nervous system, that she lost the infant upon which she had based all her anticipations of greatness; and although the King hastened to condole with her upon her disappointment, and even remained in constant attendance upon her sick-bed until she was partially convalescent, the great link between them was necessarily broken; a fact of which she was so well aware that her temper gave way beneath the trial, and she bitterly upbraided her royal lover for the treachery of which she declared him to have been guilty in permitting his ministers to effect his betrothal with Marie de Medicis, when she had herself, as she affirmed, sacrificed everything for his sake.  In order to pacify her anger, the King loaded her with new gifts, and consoled her by new protestations; nor did his weakness end there, for so soon as her health was sufficiently re-established, he wrote to entreat of her to join him at Lyons; although not before she had addressed to him a most submissive letter, in which she assured him that her whole happiness depended upon his affection, and that as she had too late become aware that his high rank had placed an inseparable barrier between them, and that her own insignificance precluded the possibility of her ever becoming his wife, she at least implored of him to leave to her the happiness of still remaining his mistress, and to continue to feel for her the same tenderness, with so many demonstrations of which he had hitherto honoured her.[93]

This was an appeal to which the enamoured monarch willingly responded, and the nature of her reception at Lyons tended still further to restore peace between them.  What the Lyonnese had previously done in honour of Diane de Poitiers, when, as the accredited and official mistress of Henri II, she visited their city, they repeated in honour of Madame de Verneuil, whose entrance within their gates was rather that of a crowned queen than a fallen woman; and this triumph was shortly afterwards augmented by her reception of the standards taken by the King at Charbonnieres, which he caused to be conveyed to her as a proof of his devotion, and which she, with ostentatious pomp, transferred to the church of St. Just.

From Lyons, Henry proceeded to Grenoble, still accompanied by Madame de Verneuil, the Duke of Savoy having at length declared that rather than submit to the conditions which had been proposed to him, he would incur the hazard of a war.  In consequence of this decision, immediate measures were taken by the French generals to march upon Saluzzo; and the Marechal de Biron, although already strongly suspected of disaffection to his sovereign, having collected a body of troops, possessed himself of the whole territory of Brescia.  The town of Bourg was stormed by Du Terrail,[94] and taken, with the exception of the citadel; while M. de Crequy[95] entered Savoy, and made himself master of the city of Montmelian, although the castle still held out.
