There seems to have intervened some considerable impediment to this proposed exchange.[16] The commission to John Hull and William Chancellor to convey Mordak to the north bears date 21st of (p. 015) May; and yet instructions for a negotiation with his father, the Duke of Albany, then Regent of Scotland, for the exchange, were issued to Sir Ralph Evre and others, as late as the 10th of the following December. At the parliament, however, held March 16, 1416, Henry Percy, in the presence of the King himself, does homage for his lands and honours. And, before Henry's death, the Pell Rolls record payments to this Earl of Northumberland, appointed guardian of Berwick and the East March, as regularly as, in the early part of Henry IV.'s reign, issues had been made to his father Hotspur, and his grandfather, the aged Earl, for the execution of the same duties. The lands of the Percies, on their attainder, were confiscated, and given to the King's brother, the Duke of Bedford; to whom, on restoring his lands and honours to the young Earl, Henry made an annual compensation in part at least for the loss.[17] [Footnote 16: Minutes of Council, 21 May and 10 Dec. 1415. Addit. MS. 4600. Art. 147.] [Footnote 17: Pell Rolls, Mich. 4. Hen. V. Many documents also in Rymer refer to this transaction.] Another example of generous behaviour in the young King towards those whom he had in his power, and of whom less noble minds would have entertained suspicion and jealousy, is seen in his conduct towards the Earl of March.[18] This young nobleman, by the law of (p. 016) primogeniture, was rightful heir to the throne; being descended from Lionel Duke of Clarence, third son of Edward III. And so much was he a cause of apprehension and uneasiness to Henry IV. and his council, that it was thought necessary to keep him in close custody, and also near the person of the King, whenever the court removed towards the borders of the kingdom. It was in the name of this young man that his uncle Edmund Mortimer excited all his tenantry and dependents to join Owyn Glyndowr in rebellion against Henry IV; and on all occasions the malcontents of the whole country, supposing Richard to be dead, held forth the Earl of March as their liege sovereign. Henry V. could not have been charged with unwarrantable suspicions or severity, had he continued the same system of watchfulness over this formidable personage, which had been observed under the reign of his predecessor. Provided only that he treated him with kindness, few would have wondered or complained if he had still kept him as a prisoner on parole.[19] But Henry, to whose guardianship, whilst Prince (p. 017) of Wales, the young Earl had been intrusted, was no sooner seated on the throne, than he admitted this young man into a full share of his confidence; not with the suspicion of a rival, nor with the fear of an
