The appeal was consequently made in vain.  Enriched by the careful policy of the Cardinal, Gaston sought only to profit by his suddenly-attained wealth; and despite the entreaties of his wife, whose youth, beauty, and accomplishments might well, for a time at least, have commanded his respect, he plunged into the most puerile and degrading pleasures, and abandoned himself to a life of alternate indolence and dissipation.  The immense fortune of the Duchess, which had moreover been greatly increased by the accumulated interest of a long minority, was wasted in the most shameful orgies, amid dissolute and unseemly associates; and even while he was awaiting with undisguised anxiety the birth of a son who, as he fondly trusted, would one day fill the throne of France, no sentiment of forbearance towards the expectant mother could induce him to sacrifice his own selfish passions.[102]

On the 29th of May the desired event took place, but to the extreme mortification of the Duc d’Orleans it was announced that the Duchess had given birth to a daughter—­the Princess who subsequently became famous during the reign of Louis XIV under the title of La Grande Mademoiselle.  Nor was this the greatest trial which Gaston was destined to endure, as four days subsequently the unfortunate Duchess breathed her last, to the regret of the whole Court, to whom she had become endeared by her gentleness and urbanity; and to the deep grief of the Queen-mother, who saw in this deplorable event the overthrow of her most cherished prospects.  Louis XIII was, however, far from participating in the general feeling of sorrow, nor did he seek to conceal his exultation.

“You weep, Madame,” he said coldly to Marie de Medicis, whom he found absorbed in grief; “leave tears to your son, who will soon be enabled to drown them in dissipation.  You will do well also not to expose him for some time to come to the chance of a second disappointment of the same nature; he is scarcely fitted for a married life, and has signally failed in his first attempt at domestic happiness.”  The Queen-mother offered no reply to this injunction; but while the King and Richelieu were absorbed by the invasion of Buckingham, and the persecution of the Protestants, she commenced a negotiation with the Grand Duke of Florence which had for its object an alliance between the widowed Gaston and one of the daughters of that Prince.

Buckingham had been repulsed by the French troops before the Island of Rhe, but had ultimately effected a landing; and on the 28th of June the King left Paris in order to join the army at La Rochelle, and to prevent a junction between the English general and the reformed party.  He had already been threatened by symptoms of fever, but his anxiety to oppose the enemy was so great that he disregarded the representations and entreaties of those about him, and proceeded to Beaulieu, where he slept.  Shortly after his arrival in that town his malady increased, but he still refused to follow the advice of his physicians, and on the morrow advanced as far as Villeroy, where, however, he was compelled to remain, being utterly incapable of further exertion.
