Accordingly, Margaret turned her eyes toward Portugal for aid, and employed John Butler, Earl of Ormond, to enlist Alphonso in her cause. Ormond, who, upon the execution of his brother, the Earl of Wiltshire, after Towton, had become the chief of the Butlers, was one of the most accomplished gentlemen of his age, and a master of the various languages then spoken in Europe. No fitter embassador could have been found; but he was not successful. In fact, although Alphonso was all his life engaged in chimerical enterprises, he could hardly have indulged in the delusion of being able to wrest a crown from Edward Plantagenet and Richard Neville. Not even that knight-errant would risk reputation against such odds. At all events the negotiation appears to have come to naught; and Ormond, doubtless, convinced that the fortunes of Lancaster were hopeless, returned to England, and made his submission. Edward restored the accomplished nobleman to the honors and estates of the Butlers, with a complimentary remark. "If good-breeding and liberal qualities," said the king, "were lost in all the world, they would still be found in the Earl of Ormond." About the time when Ormond's mission failed, Margaret received intelligence that her husband had fallen into the hands of her enemies. Finding, perhaps, that Scottish hospitality was hard to bear, Henry, about a year after Hexham, removed to the north of England, and in July, 1465, while sitting at dinner in Waddington Hall, he was seized by Sir John Harrington, and sent prisoner to London. At Islington the captive king was met by Warwick, who lodged him securely in the Tower; and Henry, treated with humanity, forgot, in the practice of a monkish devotion, the crown he had lost and the world he had left. The captivity of their king was not the only misfortune which, at this period, befell the Lancastrians. In 1467, Harleck Castle, their last strong-hold, was under the necessity of yielding. Davydd ap Jefan ap Einion held out to the last; but when the garrison was on the point of starvation, the brave Welsh captain listened to the dictates of humanity, and surrendered with honor.
