The next business was to get Warbeck out of his sanctuary and into the hands of the king. Beaulieu was surrounded by an armed force, and all attempts at escape made impossible. Some of Henry's council urged him to omit all ceremony, and take the pretender from the sanctuary by force; but this he declined, preferring to lure him thence by fair promises. After hesitating for some time, Warbeck at length threw himself upon the king's mercy. Henry then set out to London with his captive in his train. Warbeck rode in the king's suite through the city, along Cheapside, Cornhill, and to the Tower, and thence to Westminster. As the king had promised him his life, he kept his word. He was repeatedly examined by the Privy Council, but it seems as if something had transpired there which Henry deemed better concealed, for a profound silence was preserved on the subject of these disclosures. So far from even being degraded, like Lambert Simnel, to some menial occupation, Warbeck was suffered to enjoy a certain degree of liberty, and was treated as a gentleman. The probability is, that the king satisfied himself that this mysterious personage was in reality a son of Edward IV., by the handsome Jewess, Catherine de Faro, his birth being in Flanders, and agreeing exactly with the time of Edward's exile there. This might account for his admirable support of the character of a prince, for his confidence in his assertion of it for so many years, and the power he had of winning the strong attachment of persons of the highest rank and education. If this were true, he was, moreover, the queen's brother, though an illegitimate one, and might win the interest of herself and sisters by his resemblance in person, and in spirit and ambition, to her father.

But however this might be, he was too dangerous a person to be allowed to get loose again. He lived at Court under a strict surveillance, and he grew so weary of it, that he contrived to make his escape on the 8th of June, 1498. The alarm was instantly given; numbers of persons were out in pursuit of him; every road by which he might escape to sea was vigilantly beset, and the unhappy man, finding himself pressed on all sides, surrendered himself to the Prior of Sheen, near Richmond. The prior exercised the right of sanctuary possessed by the house, and refused to give him up to the king, except under pledge that his life should be spared. Henry agreed, but he confirmed the public opinion, which, excited by the mystery of the Court, fully believed Warbeck a son of Edward's, by now endeavouring to degrade him, and to fix upon him the old story. For this purpose he compelled him to sit in the stocks two whole days, on the 14th of June at Westminster Hall, and on the 15th in Cheapside, and there to read aloud to the people a confession made up of the account of him published in Henry's former proclamation, but with some very contradictory additions. This confession was then printed and circulated amongst the people, but failed entirely to satisfy any one. When this bitter purgatory had been passed through, the bitterest conceivable to a man of Warbeck's character, pretensions, and superior mind, he was committed to the Tower.

Warbeck had not been long in the Tower when there was an attempt to liberate the Earl of Warwick, who was still in confinement there; and it failed only through the conspirators not having properly informed themselves of the real quarter in which he was kept. Soon after that a fresh plot was set on foot for the same object. In this the King of France was said to be concerned. It was said that he had declared his regret for ever having countenanced the usurpation of Henry Tudor, and that he offered money, ships, and even troops, to the friends of Warwick to enable them to release him, and place him on the throne. The Yorkist malcontents were once more active. They wrote to the retainers of the late Duke of Clarence, the father of Warwick, and to Lady Warwick, to come forward and see justice done to the oppressed prince; and an invitation was sent from the Court of France to a distinguished leader of the house of York to go over to that country and assume the command of the expedition. This also failing, a report was then spread of the death of the Earl of Warwick: then it was said that he had escaped, and a person of the name of Ralph Wulford, or Wilford, the son of a shoemaker in Sussex, was taught by one Patrick, an Augustinian friar, to personate the earl.

Whether the Yorkists were determined to give Henry no repose, but to haunt and harass him with a perpetual succession of impostors, or whether Henry himself planned this latter improbable scheme as a pretext for getting rid of the Earl of Warwick altogether, seems never to have been satisfactorily cleared up. All that is known is, that Wulford and the friar were speedily arrested, whereupon Wulford was put to death, and the friar consigned to prison for life.

Scarcely had this blown over, when it was reported that Warbeck and Warwick had endeavoured to escape from the Tower together. Warbeck must have been allowed to have free access to Warwick after he was sent to the Tower—a circumstance not likely to have been permitted by the cautious and vigilant Henry VII. had he not had some ulterior purpose in it. Once together, however, Warbeck won the favour of the simple and inexperienced Warwick, who was as ignorant of the world as a child, having passed nearly all his life in prison. Warbeck, however, exercised the same fascination over the highest and most intelligent persons whenever he had access to them. To the Tower he carried his active spirit of intrigue and adventure, and we soon find him in the enjoyment, for so dangerous a character, of extraordinary liberty and range in that State prison. He had not only completely won over the Earl of Warwick, but their keepers, Strangways, Astwood, Long Roger, and Blewet. These men engaged to murder their master, Sir John Digby, the Governor of the Tower, to get possession of the keys, and to conduct Warbeck and Warwick to the Yorkist partisans, by whom Warbeck was to be proclaimed King Richard IV., and Warwick to be restored to his titles and estates.

This plot, it is said, was discovered in time; and this was another circumstance which caused the public to suspect that the whole thing had been of the contriving, or, at least, of the permission of Henry, to rid him of these troublesome aspirants. The two offenders were immediately confined in separate cells. The servants of the Governor were brought to trial, and Blewet and Astwood were condemned and hanged. On the 16th of November, Warbeck was arraigned in Westminster Hall for sundry acts of high treason, since as a foreigner he had come into these kingdoms. They were, in fact, the attempts on the crown which we have related. He was condemned and hanged at Tyburn on the 23rd of November, 1499. On the scaffold his confession was read, and he declared it, on the word of a dying man, to be wholly true. Such was the end of this extraordinary adventurer. Bacon describes his enterprise as "one of the largest plays of the kind that hath been in memory; and might, perhaps, have had another end if he had not met with a king both wise, stout, and fortunate."

On the 21st of November, the Earl of Warwick was brought to trial before the peers, though he had been attainted from his birth, and had never taken his oath and seat as a peer of the realm. The charge against him was his conspiracy with Warbeck to dethrone the king. The poor youth pleaded guilty, either as weary of a life which had been but one long injury and wrong, in consequence of his birth, or because he was destitute, from his perpetual confinement, of the activity of mind to comprehend his situation. Probably he imagined that if he confessed himself guilty, he would be pardoned, and sent back to his cell. But Henry had no such intention. The Earl of Oxford, as Lord Steward, pronounced judgment, and three days afterwards he was beheaded on Tower Hill. Thus perished the last legitimate descendant of the Plantagenets who could alarm the fears of Henry Tudor.

A few months after these tragic events, a plague broke out in London, which the people considered as a direct judgment from Heaven for such wicked bloodshed. Henry got out of town, but not feeling himself safe, after several changes of residence, he went over to Calais, and whilst there he had an interview with the Archduke Philip of Burgundy. Henry invited the archduke to take up his quarters in Calais, but it is a proof of the distrust which even his own allies entertained of the politic Henry, that the archduke declined putting himself into his power, and agreed to meet him at St. Pierre, near that city. What the archduke was particularly anxious to see Henry for, was to excite his jealousy of France, and secure his co-operation in counteracting its ambition.

Charles VIII. of France, an ambitious youth, had made a grand expedition into Italy to seize on the two Sicilies, having contrived to make out a claim upon them, which, though empty in itself, was good enough for an excuse for conquest. He had passed over the Alps with an army of upwards of 30,000 men. At first all gave way before him, but an extensive league was soon formed against the French encroachment, including Ferdinand of Spain, Maximilian, the King of the Romans, the father of Philip, the Duke of Milan, and the Doge of Venice. Charles, who had led a most dissipated life, died suddenly in 1498 at the castle of Amboise, and the Duke of Orleans succeeded as Louis XII. Louis was as fully bent as Charles had been on prosecuting the conquest of Naples and Sicily, and in 1499 marched with a fresh army into the south of Italy.

It was to secure Henry's assistance in the league against the aggression of France, which alarmed all Europe, that Philip used his most eloquent persuasives, but the only persuasives with Henry were moneys, and these Louis had already extended. He renewed the peace of Étaples, paid up the arrears of Henry's pension, and secured the interest of the Pope, with whom Henry was desirous to stand well, by paying him 20,000 ducats for a dispensation enabling him to divorce his wife, and marry Anne of Brittany, the widow of Charles VIII., and an old flame of his. He had also made over the Valentinois, in Dauphiné, with a pension of 20,000 livres, to the Pope's son, the vile Cæsar Borgia. The Pope, moreover, was coquetting with Henry, inviting him, by an express nuncio, to join a league for an imaginary crusade to the Holy Land, which Henry was ready to do for the cession of some real ports in Italy as places for the retreat and security of his fleet in those seas.
