Villena’s son, who, fearing betrayal, had refused to enter the city when he had come with the King weeks before, and had remained in the neighbourhood at the famous Geronomite monastery of El Parral, founded by his father, fled at the news. His father, with Alburquerque and the Constable of Castile, Count of Haro, at once met at Cuellar, and sent an insolent order to Henry to expel his sister from Segovia. It came too late, however. The King, by this time, had met Isabel, who had received him at the gate of the Alcazar, and professed her love and duty to him. In a speech full of womanly wisdom,[19] she said she had come to pray him to put aside anger towards her, for she meant no evil; and all she asked was that he should fulfil his oath taken at Toros de Guisando, and acknowledge her as heiress of Castile. ‘For by the laws of God and man, the succession belonged to her.’ Weak Henry swayed from one side to the other like a reed in the wind, as either party had his ear; and at last Isabel took the bold course of sending secretly for Ferdinand, who had just returned from Aragon. The risk was great, but Isabel knew, at least, that she could depend upon the Commander of the Alcazar of Segovia, and Ferdinand secretly entered the fortress on the 4th January 1474. It was a difficult matter for Doña Beatriz to persuade the King to receive his young brother-in-law; but she succeeded at last, and when Henry had consented, he did the thing handsomely, and they all rode together through the city in state, with great show of affection and rejoicing. On Twelfth Day, Doña Beatriz and her husband gave a great banquet to the royal party[20] at the Bishop’s palace, between the Alcazar and the Cathedral. Whilst the minstrels were playing in the hall after dinner, the King suddenly fell ill. Violent vomiting and purging seemed to point to poison, and the alarm was great. Prayers and processions continued night and day, and the unfortunate man seemed to recover; but, though he lived for nearly a year longer, he never was well again, the irritation of the stomach continuing incessantly until he sank from weakness.
In the interim both factions interminably worried him to settle the succession. Sometimes he would lean to Isabel’s friends, sometimes to Villena and Alburquerque, but Isabel herself, wise and cautious, knew where safety alone for her could be found, and took care not to stir outside the Alcazar of Segovia, in the firm keeping of Cabrera, who himself was in the firm keeping of his wife, Doña Beatriz. Once in the summer it was found that the King had treacherously agreed that Villena’s forces should surreptitiously enter the town and occupy the towers of the cathedral, whence they might throw explosives into the Alcazar and capture Isabel on the ground that she was poisoning the King; but the plan was frustrated, and Henry, either in fear or ashamed of his part of the transaction, left Segovia to place himself in the hands of Villena at Cuellar. Greedy to the last, Villena carried the sick King to Estremadura to obtain the surrender of some towns there that he coveted; but to Henry’s expressed grief, and the relief of the country, the insatiable favourite died unexpectedly of a malignant gathering in the throat on the way, and the King returned to Madrid, himself a dying man. His worthless life flickered out before dawn on the 12th December 1474, and his last plans were for the rehabilitation of the Beltraneja. He is said to have left a will bequeathing her the succession; but Cardinal Mendoza, Count Benavente, and his other executors, never produced such a document, which, moreover, would have been repudiated now by the nation at large, passionately loyal, as it already mainly was, to Isabel.[21]
