Paris, which had celebrated his accession with even more than the usual ceremonial, jousts, and tourneys, was greatly alarmed at the threat of the Connétable de Bourbon to march upon it with the allied forces of the King of England and of Charles V. The king, to reassure them, sent them the Sire de Brion, who declared to them that their monarch "had so much consideration for the city of Paris that he would sacrifice himself rather than allow it to be taken, that he was willing to expose his life in order to defend it, to live and to die with the Parisians, and that, if he could not come to it in person, he would send to it his wife, his children, and his mother, and all that he had and possessed, persuaded as he was that when he had lost the rest of the kingdom, he would readily recover all his losses if he could preserve Paris; that he had the intention to bring to it ten thousand Swiss, that he was aware of the attachment which the Parlement and the city bore to his person, that he thanked them for it, and exhorted them to continue a fidelity which was so useful to him."
All these fine words gave great pleasure to the citizens, and they were thrown into corresponding consternation when the news was received, on the 7th of March, 1525, that he had been taken prisoner at Pavia. His mother, Louise de Savoie, subordinated the evil traits of her character to constitute herself an intelligent regent; and on the 14th of April, 1527, the king made a triumphal re-entry into his capital after his release. Some doubts seem to have been entertained as to the genuineness of the welcome, for, it is recorded, the _prévôt_ of the merchants, the _échevins_, and the school-masters were ordered to station, at a dozen points on the route of the procession, groups of eighty or a hundred children, who were to cry enthusiastically: "_Vive le roi!_" The quibbling by which François endeavored to justify his refusal to carry out the provisions of the treaty of Madrid, for which he had left his two sons as hostages, deceived no one; Charles V very justly proclaimed him a traitor and perjured, to which the king had no better answer than that the emperor "lied in his throat," and that he would meet him in the lists in single combat whenever he liked.
