Luynes, however, continued to offend her. At the end of 1618, an embassy from Savoy came to Paris to demand the hand of her younger daughter, Christine, for the Prince of Piedmont, eldest son of Charles Emmanuel. Marie was not consulted, the King confining himself to informing her of the betrothal; and on February 10, 1619, the marriage was celebrated without her being invited. It was the last straw; she resolved to fly at the first favourable opportunity. D’Épernon, anticipating her intention, had left Metz, towards the end of January, without permission of the King, and gone to await her in the Angoumois; and, in the night of February 21-22, Marie made her escape to Blois and went to Angoulême, whence she wrote to her son, demanding the redress of her grievances. Luynes was at first greatly alarmed, fearing that the Princes, already beginning to show signs of irritation at the increasing power of the favourite, might join the Queen-Mother; but they remained quiet. In these circumstances, he might easily have crushed d’Épernon; but he wished to avoid war, and accordingly sent the Cardinal de la Rochefoucauld and Père Bérulle, the famous preacher of the Oratoire, to propose peace to Marie, and recalled Richelieu from Avignon “to pacify her mind.” In this task the prelate succeeded, and on April 30, 1619, he signed with the Cardinal de la Rochefoucauld a treaty at Angoulême which authorised the Queen-Mother to dispose of the offices of her Household and to reside where she pleased, and gave her, in exchange for the government of Normandy, that of Anjou, with the Château of Angers, the Ponts-de-Cé and Chinon. D’Épernon, against whom the usual royal declaration had been launched, recovered his charges and appointments, and Richelieu was given to understand that he might hope for a cardinal’s hat at no very distant date. However, Louis XIII, who had been on the point of setting out with the Court for the Loire when the news that peace had been signed reached him, determined to carry out his intention, Luynes no doubt thinking that, in view of the possibility of further trouble with the Queen-Mother, a visit of the young King to that part of his realm might be productive of good results. After a short stay at different towns, including Amboise, from which letters announcing the peace were sent to the Parlement of Paris for registration, at the end of May the Court arrived at Tours, where, says Bassompierre, “we remained three months and passed our time very pleasantly.” Arnauld d’Andilly, in his _Mémoires_, has left us an interesting picture of life at Tours and, more particularly, of the lavish hospitality dispensed by Bassompierre:--
