On the 11th of March 1513 Cardinal John de Medicis, then in his thirty-sixth year, was unanimously elected Pope by the twenty-four Cardinals assembled in conclave. The new Pope (Leo X.), who was of a peaceful and diplomatic nature, refused to ratify a treaty concluded at Malines on the 5th of April in the same year between Margaret, acting for her father, and Henry VIII.'s ambassadors; a treaty which would have forced him to send the papal troops to invade Provence or Dauphiny. He arranged a truce with Louis XII., who, after Gaston de Foix's death, had lost most of his Italian possessions. The Sforzas were reinstated in Milan, the Medicis in Florence, and Genoa became once more a free republic; the king's army was beaten by the Swiss at Novara, and by the English at Guinegate. A treaty signed at Blois, on the 28th of March, was ratified at Venice on the 11th of April. The Venetian republic agreed to help Louis to regain Milan and Genoa, and the king promised to assist the Venetians to recover their territories on the mainland, which were occupied by Maximilian's troops. The political balance of Europe now depended entirely on the goodwill of Henry VIII. On the 25th of May 1513 Jean le Veau wrote to Margaret that 'the time had come to be firm, and that she ought to imitate the English, who always showed their enmity against France.' A treaty was concluded through Margaret's intervention in 1513 between the emperor and Henry VIII., which aimed at humbling France, but only resulted in the battle of Guinegate, where Maximilian served as a volunteer in the English army, and received a hundred crowns a day as pay. It was on this occasion that Margaret ordered the town of Therouenne on the borders of France and Belgium to be completely destroyed. Whilst he was with the English army Maximilian sent a messenger to Margaret asking her to join him at Tournay. In reply she says: 'Monseigneur, I have received the message that you have been pleased to send me by Marnix, my secretary, about my going to Tournay. As for me, Monseigneur, if you think that my going there is necessary, and can be of service to you, I am ready in this and in all else that it may please you to command me; but otherwise, it is not fitting for a widow to be trotting about and visiting armies for pleasure....' But a little later, after the reduction of Tournay, Margaret met her father and Henry VIII. at Lille.
