In the month of October 1513 the king and emperor still appeared to be willing to fulfil the contract, and signed a treaty arranging that Maximilian and Margaret should accompany the Archduke Charles to Calais before the 15th of May following for the celebration of the marriage. But six months later Ferdinand and Louis signed another treaty agreeing to marry the archduke to Renée, Louis XII.'s daughter, who was barely four years old. Ferdinand, as Charles's maternal grandfather, claimed the right to control the marriage of his grandson and heir. He informed Maximilian of the contents of the treaty, but begged him to keep it secret from Margaret, as _he_ intended to keep it secret from the English king. Margaret, left in ignorance, continued to beg her father to celebrate the archduke's marriage with Princess Mary, but the emperor always evaded her requests with fresh excuses. She reproached him for his negligence in a letter written in March 1514 in which she showed how necessary it was that he should hasten the marriage to secure peace to the Austrian dominions, and especially to the Netherlands. Anne of Brittany had been in failing health for some years, and as far back as 1511 had had a serious illness which placed her life in danger. De Burgo, Margaret's ambassador at the French Court, in one of his letters to his mistress's secretary says: 'The queen, as I lately informed Madame, was nearly well again, but last night she was suddenly attacked with fever and other symptoms so violently that her life was in danger.' Later on he wrote that the patient had had such a bad night, she had lost all power of speech, but after having received the last sacraments she gradually became better. Anne recovered, and on the 4th of April De Burgo wrote the news of her convalescence. But on the 23rd of January of the following year Jean Leveau informed Margaret that 'the day before yesterday, which was the 21st of this month, at three o'clock in the afternoon, the queen was delivered of a still-born son, much to the king's grief, though others take it calmly since God wills it thus.' This was Anne's last child. In the following March she again had fever, and did not leave her bed until May. De Burgo gave Margaret an account of an audience he had with Anne on the 19th of May. 'Madame, although the queen is not yet quite well and speaks to no stranger, she was pleased to wish to see me, to hear what the emperor had written to me about some days ago, and that I might take leave of her; I found her in bed, but looking well, and much improved in health.' Anne, however, never really recovered, and on January the 9th, 1514, passed away at Blois, leaving the king with only two daughters, Claude and Renée. Ferdinand soon tried to find Louis another wife, and proposed that he should marry Margaret, who was now thirty-four years old, or her niece Eleanor, who was only seventeen. Louis chose the latter, and had the marriage articles drawn up.
