Ferdinand knew that the surest pledge he could have of Maximilian's effective co-operation would be the presence of Margaret in Spain, especially if he could manage to get her into his possession before his own daughter Joanna was sent to Flanders. 'If it be managed without inconvenience we should like Madame Margaret to come hither as soon as the betrothal is effected, before the Infanta our daughter goes; immediately if the weather will permit.... It may be done as follows. If at the time of the formal betrothal there are any ships there belonging to our subjects, sufficient to bring the Archduchess safely, the weather being fair, Rojas (_i.e._ Ferdinand's envoy in Flanders) may take all such vessels at such freight as he can, to be paid on their arrival here in Spain, and bring her in the fleet with God's grace. Her coming thus would be safer, for she would arrive before the affair was publicly known, and if it can be done you will not delay for the Archduchess's trousseau, ornaments, and household baggage, which can be sent afterwards.' But, continues the King of Aragon, if it cannot be done, Joanna shall be sent in a Spanish fleet, and Margaret can embark in it on its return to Spain. The careful Ferdinand remarks in his instructions that he intended to send with his daughter only eight ladies and the other attendants strictly necessary, and although Maximilian was not to be told this in as many words, he was to be persuaded to limit his daughter's household to accompany her to Spain to the smallest possible proportions. But Maximilian, who was as wary as Ferdinand, had no notion of allowing his daughter to be sent to Spain before the Spanish Infanta arrived in Flanders, and it was early in March of the year 1497 before Margaret first set her foot on Spanish soil at Santander. Seven months afterwards fate dealt its first crushing blow upon Ferdinand's plans, and the bride, not yet eighteen, found herself a widow. She had become greatly beloved in Spain, and Ferdinand and Isabel, especially the latter, in the midst of their own grief, cherished the daughter-in-law who might yet, they hoped, give them an heir to the crowns of Spain. Ferdinand, in conveying (in December 1497) the news of his son's death to his ambassador for the information of Maximilian, wrote: 'Tell him that our distress has prevented us from sending him the news earlier, and that our grief is increased by considerations for Princess Margaret, although she tries very hard, as befits her, to bear her trouble gently and wisely; and we try our best to console and please her, endeavouring to make her forget her loss. Her pregnancy, thanks be to God, goes on well, and we hope in His mercy that the result will be a reparation and consolation for our trouble. We do, and will, take as much care of the Princess as we would of her husband if he were alive, and she will always fill the same place as he did in our hearts.'
