In November 1508 Edward Wingfield wrote to Margaret to inform her that 'Henry VII. has it much at heart that the affairs of the Emperor and the Prince, his son (Prince Charles, his grandson), should be settled to the greatest advantage in the approaching Congress of Cambray, and that their enemies should be entirely discomfited. As long as the alliance between the King of France and the King of Aragon continues, he says, it is to be feared that the principal enemy of the Emperor and Prince Charles will triumph. For if he be assisted by France, the King of Aragon will most probably be able, not only to keep the usurped government of Castile in his own hands, and the other dominions belonging to that kingdom, as long as he lives, but also to deprive the Prince of his right of succession. To prevent this, it seems to Henry that the best plan would be to exclude the King of Aragon from the treaties that are to be made at Cambray, and to sever the alliance existing between him and the King of France. The King of Aragon has usurped the government of Castile only by means of the help of the King of France. If he were to be isolated, he would be unable to preserve it, and the Emperor would have it in his power, aided by those who are inimical to the King of Aragon, to take the government of that kingdom into his own hands....'[35] Margaret also kept ostensibly on the most friendly terms with Louis XII., whose correspondence with her about this time shows that to him at least she concealed her hatred of France. In each of his letters he takes a pleasure in reminding her of their early friendship and of their childish games, in the days when she was 'la petite Reine' at Amboise. [35] _Lettres de Louis XII._ It is evident that being on such excellent terms with the chief sovereigns in Europe gave Margaret some advantage where negotiations and treaties were concerned. In fact she intervened as arbitrator or negotiator in most of the political events of this time. Her experience and knowledge of different countries made her old for her years. 'Madame Margaret,' says Jean le Maire, 'has seen and experienced more at her youthful age... than any lady on record, however long her life.'
