On the 18th of July, at ten o'clock at night, the widow of Henri IV, attended only by Madame du Fargis, who had secretly reached Compiègne in order to bear her company during her flight, and by M. de la Mazure the lieutenant of her guard, stepped into a carriage which had been prepared for her, rapidly crossed the ferry, and took the road to La Capelle; but before she could reach her destined haven, she was met by M. de Vardes, who, with every demonstration of regret, informed her that her design having by some extraordinary chance been suspected by Richelieu, the Marquis his father, who was devoted to the minister, had been hurriedly ordered to return to La Capelle, where he had arrived on the previous evening; had shown himself to the garrison and magistrates; and had commanded his son to leave the town upon the instant. Agitated as she was, the Queen-mother did not fail even at that moment, and, as some historians state, most justly, to suspect that she had been betrayed either by the fears or the venality of the very individual before her; but hastily offering her acknowledgments for his timely warning, she repressed her resentment, and gave instant directions to her attendants to proceed with all speed to Avesnes in Hainault. So well was she obeyed that on the first day of her journey she travelled a distance of twenty leagues, disregarding the entreaties of Madame du Fargis, who represented to her the necessity of some temporary repose; and persisting in her purpose so resolutely that on the 20th of July she reached her destination, and placed herself beyond the reach of her pursuers, who had, however, so languidly performed their duty that it was openly declared that they had rather been despatched by Richelieu to drive her from the kingdom than to compel her to remain within it. On her arrival at Avesnes the royal fugitive was received with all imaginable honour by the Marquis de Crèvecoeur, the Governor of the fortress; the troops were under arms; and she was escorted by the dignitaries of the city to the Hôtel-de-Ville, where she took up her temporary residence. The Baron de Guépé was instantly despatched to Brussels to announce her arrival to the Archduchess; and the Prince d'Epinoy, the Governor of the county, waited upon her Majesty, to entreat that she would remove to Mons, where Isabella was preparing to welcome her. During her sojourn at Avesnes, Marie despatched three letters to Paris, in which she respectively informed the King, the Parliament, and the municipality of her reasons for leaving the country.
