A.D. 1282.--The King of England, encouraged by the aforesaid victory, and seeing a way open to him for the fulfilment of his desires, lest there should be any impediment to his carrying his wishes into effect, entered in triumph with his men the safe and secret hiding-place of the Welsh, to wit, the province of Snowdon; he held Easter in a monastery of Cistercian monks, called in their tongue Aberconway, and situated within the bounds of the aforesaid province. Then he was able to control, as master, the castles and fortified places, both within Snowdon and without, except a certain castle, called in their tongue Bere. Into this castle David, the brother of Llewellyn, who had fled before the King on learning of his coming, had in vain introduced a garrison, promising to send them speedy assistance, while he himself took refuge in secret and almost inaccessible woods and swamps. The castle itself was surrounded by an impassable marsh, and possessed no entrance except by narrow paths artificially constructed to overcome the natural difficulties of the ground. When the King found this out, he carefully closed up the entrances and exits and besieged the defenders so straitly that, giving up hope of any succour, they were compelled to surrender the castle and trust to the clemency of the King, who graciously granted them freedom of life and limb. Then the King, by a lavish distribution of gifts and presents, entered privily into an agreement with some of the natives who knew the hidden ways and secret retreats, and they, not without joy, compelled David to withdraw from his refuge, and surrendered him to the King, who sent him, as was only just, to be imprisoned, along with his wife and son, at Rhuddlan. This took place about the Feast of S. Botulf.... About Michaelmas, the King, summoning the nobles and mayors of the cities to meet him at Salisbury, held a Parliament, and caused David, who had been imprisoned at Rhuddlan, to be brought before him; and after consideration of his misdeeds, had him condemned to death, by advice of the magnates.
