The forces employed were not less than thirty thousand men, without counting the troops on the lines of communication at Newcastle and Durham. To feed such a body in the depth of winter, in a sparsely-peopled and hostile country and with only one road open, was no mean task. Nevertheless the arrangements of Warwick worked with perfect smoothness and accuracy,--good witness to the fact that his talent for organisation was as great as his talent for the use of troops in the field. Every morning, we are told, the Earl rode out and visited all the three sieges "for to oversee; and if they wanted victuals or any other thing he was ready to purvey it to them with all his power." His day's ride was not less than thirty miles in all. The army was in good spirits and sure of success. "We have people enow here," wrote John Paston, whose duty it was to escort Norfolk's convoys to and fro, "so make as merry as ye can at home, for there is no jeopardie toward."
A siege at Christmastide was the last thing that the Lancastrians had expected at the moment of their rising; they had counted on having the whole winter to strengthen their position. No hope of immediate aid from Scotland was forthcoming, and after three weeks' blockade the spirits of the defenders of Bamborough and Dunstanburgh sank so low that they commenced to think of surrender. Somerset, as we have already mentioned, had been in treaty with Warwick six months before, with the object of obtaining grace from King Edward. He now renewed his offer to Warwick, pledging himself to surrender Bamborough in return for a free pardon. Ralph Percy, the commander of Dunstanburgh, professed himself ready to make similar terms.
It is somewhat surprising to find that Warwick supported, and Edward granted, the petitions of Somerset and Percy. But it was now two years since the tragedy of Wakefield, both the King and his cousin were sincerely anxious to bring about a pacification, and they had resolved to forget their blood feud with the Beauforts. On Christmas Eve 1462, therefore, Bamborough and Dunstanburgh threw open their gates, such of their garrisons as chose to swear allegiance to King Edward being admitted to pardon, while the rest, headed by Jasper of Pembroke and Lord Roos, were allowed to retire to Scotland unarmed and with white staves in their hands. Somerset and Percy went on to Durham, where they swore allegiance to the King. Edward took them into favour and "gave them his own livery and great rewards," to Somerset in especial a grant of twenty marks a week for his personal expenses, and the promise of a pension of a thousand marks a year. As a token of his loyalty Somerset offered to take the field under Warwick against the Scots, and he was accordingly sent up to assist at the siege of Alnwick. Percy was shown equal favour; as a mark of confidence the King made him Governor of Bamborough which Somerset had just surrendered.
