On reaching the advanced guard of the French army she incurred the greatest danger, as her person was well known to the officer in command; but fortunately for the Princess he had retired to rest, and the carriage which she occupied was searched by a subordinate to whom she was a stranger. After having traversed the royal camp, the courageous fugitive mounted on horseback, and, accompanied by two trusty attendants, rode without once making a halt as far as Thionville, a town which belonged to the Spaniards; but on arriving at the gates she did not venture to enter until she had apprised the Comte de Wilthy, the governor, of the step which she had taken; and her fatigue was so excessive that, during the absence of her messenger, she dismounted with considerable difficulty and flung herself down upon the grass that fringed the ditch; a circumstance which attracted the attention of the sentinel at the gate, who pointed her out to a comrade, exclaiming at the same time:
“Yon is a stripling who is new to hard work, or I am mistaken.”
Meanwhile the errant Princess was faint from exhaustion, and sick with suspense; but she was soon relieved from her apprehensions by the appearance of the Governor and his wife, by whom she was welcomed with respect and cordiality; apartments were assigned to her in their own residence; and under their protection she remained for several days at Thionville, in order to recruit her strength, as well as to inform Monsieur of her approach, and to request an escort to Brussels. Both Gaston and the Queen-mother were overjoyed at her escape; for although estranged by the jealousies and intrigues of those about them, Marie fully participated in the delight of her son, as she trusted that the presence of a daughter-in-law, who shared her enmity towards the Cardinal, would tend to ameliorate her own position. Carriages and attendants were immediately despatched to Thionville, while Monsieur proceeded to Namur to meet the Princess, and to conduct her to Brussels, where she was impatiently expected. On alighting at the palace Madame was received with open arms by her mother-in-law, who had returned to the capital in order to congratulate her on the happy result of her enterprise, and was greeted by the Archduchess with equal warmth. The Spanish Cabinet accorded an augmentation of fifteen thousand crowns monthly to the pension of Monsieur for the maintenance of her household, and this liberality was emulated by Isabella, who overwhelmed her with the most costly presents.[196]
