The Wars of the Roses - Alison Weir [192]
Warwick had meanwhile captured Warkworth Castle and made it his headquarters. He now laid siege to Bamburgh Castle, which occupied a wonderful strategic position, standing sentinel over the rocky Northumbrian coast. The Lancastrian garrison under Somerset held out for as long as possible, while Warwick sent messages promising Somerset a generous pension if he would surrender. In return, Somerset demanded that Sir Ralph Percy be granted custody of Bamburgh after he handed it over, that the lords with him would be restored to their estates and the lives of the garrison would be spared. Warwick agreed to these demands, and on Christmas Eve Somerset gave up the keys of the castle to him. Inside, Warwick found Margaret’s provisions and personal effects, which he sent to King Edward. Somerset now formally pledged his allegiance to Edward IV, and rode off to assist Warwick at the siege of Alnwick, Warwick having sent a force to reduce that castle and another to Dunstanburgh.
Edward had for some time cherished notions of winning over Somerset, and had therefore been prepared to be more than conciliatory, knowing that the defection of one of their staunchest adherents would be a sickening blow to his enemies. Somerset’s desertion of the Lancastrians may have been prompted by the desire for personal gain or by rivalry with Brézé for the Queen’s favour; certainly relations between himself and Margaret had been strained of late.
Conducting a siege in midwinter posed almost as many problems for the besiegers as for the besieged. Food was in short supply and weather conditions were miserable. At Alnwick, according to the chronicler Warkworth, the soldiers were soon complaining that ‘they had [to] lie there so long and were grieved with cold and rain, so that they had no courage to fight’. Nevertheless, by the feast of the Epiphany, 6 January 1463, Alnwick and Dunstanburgh had surrendered to the Yorkists, and Pembroke, unwilling to reach any compromise with Edward IV, returned to Scotland.
The surrender of these Northumbrian castles effectively ended the campaign, and the King withdrew his army south, leaving Warwick to guard the border, a task he undertook with commendable energy and efficiency. ‘King Edward now possessed the whole of England, except a castle in north Wales called Harlech,’ observed Warkworth.
With Margaret in Scotland, the King now decided to prevent her from obtaining any further support from the French by sending an embassy to negotiate a treaty of friendship, or a truce at the least, with Louis XI. When the Queen heard of his intention, she made it her aim to sabotage any attempt by Edward to win Louis over and to persuade the French king to provide further aid for her own cause.
After the Northumbrian castles had fallen, Margaret’s French and Scottish mercenaries had followed her north to Scotland, where they regrouped, and just before Lent 1463, with the Queen and Brézé at their head, they marched across the River Tweed into Northumberland. Sir Ralph Percy, the untrustworthy captain of Bamburgh, allowed the Queen’s French mercenaries into the castle, and thereby enabled the Lancastrians to take it for Henry VI. Percy was also captain of Dunstanburgh Castle, and as soon as the garrison saw the Queen approaching it also surrendered, while on 1 May, thanks to the treachery of Sir Ralph Grey, Alnwick Castle opened its gates to the invaders. Later that month
