In less than two years, however, King Richard himself was a captive in the hands of his subjects. Young Arundel and the son of the late Duke of Gloucester were appointed his keepers. “Here,” said Lancaster, as he delivered[58] Richard into their custody[59], “here is the king; he was the murderer of your fathers; I expect you to be answerable for his safety.” During the first five years of Henry the Fourth, young Arundel, among other services, shared with his sovereign the reverses which attended his invasion of the Welsh frontier, and his campaign against Owen Glendower.--But at length the scenes of the camp gave place to domestic festivities; and his approaching marriage with Donna Béatrice, daughter of John the First, king of Portugal, was publicly announced. Great preparations were made to receive the bride with all the honours due to her beauty and station; the royal palace and the earl’s ancestral castle were sumptuously fitted up for her reception. She left Portugal with a splendid retinue, made a prosperous voyage, and arrived in London in the middle of November. On the twenty-sixth of the same month the solemnity took place in the Royal Chapel, where, in the presence of the King and Queen, Donna Béatrice gave her hand to the young Earl of Arundel. Their subsequent arrival at Arundel, and the rejoicings which there met the royal bride, may be better imagined than described. All that could add to the splendour of the gala was ingeniously arranged and displayed; and on her triumphant entry under the old Norman gateway of her husband’s castle, Donna Béatrice might well confess that “the castled heights of Algarva were not so beautiful as the verdant hills, and embattled towers, of Arundel.” Among the personal exploits by which his brief career was subsequently distinguished, is the following.--During the excitement which prevailed in France in consequence of the murder of the Duke of Orleans, “the author of that assassination, Charles Duke of Burgundy, now taking the alarm, applied to the English monarch for assistance.” His request was instantly complied with; for Henry had “private motives which prompted him in this instance.” [Sidenote: 1411. {] Arundel, at the head of a strong body of archers and men-at-arms, was despatched to join the Burgundian leader, whom he met at Arras; and thence directing their march upon the capital, arrived on the twenty-third of October. The first point of attack was St. Cloud, where Arundel took charge of the assault, and marching his men to the bridge which here crosses the Seine, carried it by storm; took possession of the town with severe loss to the enemy, and returned with numerous prisoners, immense booty, and the thanks of the Burgundian chief.
