Even after the fall of Harleck, Margaret's high spirit sustained her hopes. In 1467, she is understood to have come to London, disguised as a priest, to rouse her partisans to action, and even to have had an interview with her husband in the Tower. Next year she sent Jasper Tudor to Wales; and he laid siege to Denbigh. King Edward himself was in the castle, and the utmost peril of being taken prisoner. He contrived to escape, however; and the fortress surrendered. But a Yorkist named William Herbert went with an army, and inflicted such a defeat on Jasper that he was fain to escape to the Continent. Nevertheless, in October, Margaret lay at Harfleur threatening an invasion. Edward, however, sent his brother-in-law, Anthony Woodville, who now, in right of his wife, figured as Lord Scales, to attack the fleet of his old patroness; and the exiled queen, seeing no chance of success, abandoned her expedition in despair. But even in despair Margaret could show herself heroic and sublime. Thus, when some of her Continental kinsfolk were, in a vulgar spirit, lamenting her unfortunate marriage, and describing her union with the unhappy Henry as the cause of all her misfortune, she raised her head with regal pride, and contemptuously rebuked their foolish talk. "On the day of my betrothal," exclaimed she, with poetic eloquence, "when I accepted the Rose of England, I knew that I must wear the rose entire and with all its thorns." In the midst of adversity the exiled queen had one consolation. Edward, Prince of Wales, was a son of whom any mother might have been proud, and day by day he grew more accomplished in the warlike exercises of the age. Nor, though in almost hopeless adversity, did the prince lack instruction in weightier matters; for Fortescue undertook the task of educating the banished heir of Lancaster, endeavored so to form the mind of the royal boy as to enable him to enact in after years the part of a patriot-king, and compiled for his pupil the "_De Laudibus Legum Angliæ_;" a work explaining the laws of England, and suggesting the improvements that might with advantage be introduced. Five years of exile passed over; and during that time every attempt of the Lancastrians to better their position proved disastrous. It was when matters were at the worst--when the Red Rose had disappeared, and the Red Rose-tree had withered from England--that circumstances occurred which inspired the despairing adherents of the captive king with high hopes, diverted the thoughts of the exiled queen from reminiscences of the past to speculations on the future, and opened up to her son the prospect of a throne, only to conduct him to an untimely grave.
