In the reign of William III., Hugh de Montgomery, second son of Earl Roger, and who succeeded him in the Earldom of Shrewsbury, with the Earl of Chester and Owen, a Welsh Lord, made an unexpected attack upon Wales, and committed great atrocities upon the inhabitants. Many of the Welsh fled into Ireland, and left their country to the mercy of the English. Their flight gave their enemies an opportunity of continuing their march, and they penetrated into Anglesey, where they destroyed all before them with fire and sword. While they were thus exercising their cruelties, Magnus, King of Norway, who had lately made himself master of the Isle of Man, advanced as far as Anglesey. On the English endeavouring to hinder him, the Earl of Shrewsbury was slain in the skirmish. His death was looked upon as a just judgment for the cruelties committed by him in that isle. The Earl’s death caused some disorder among the English troops, and constrained them to abandon the shore; when Magnus landed, and finding the English had left nothing to plunder, he shortly after re-embarked. Earl Roger, who succeeded his brother Hugh in the Earldom of Shrewsbury, being of a rash and discontented spirit, was among those who favoured the claims of Duke Robert, in place of Henry I. On the accession of Henry I. he rebelled, and fortified his castles in Shropshire, and at Shrewsbury built and fortified a flank wall from each side of the castle, across the isthmus, down to the Severn side; hereupon the king declared him a traitor, and marched with a considerable force against him. The earl perceiving that he had no forces to withstand the attack of the king, confessed his treason, and was shortly after banished to Normandy; but again appearing in arms, he was taken prisoner, and ended a miserable life in close confinement at Wareham. About this period the king sent several of his council to Shrewsbury, among whom were Richard de Belmarsh, bishop of London, warden of the Marches, and governor of the county of Salop, and others, to meet there Jorweth ap Blithyn, on pretence of consulting with him about the king’s affairs; but when he came there, contrary to all equity, he was condemned for treason and committed to prison. The Marches of Wales are supposed to have been settled by the Saxons, to prevent the incursions of the Welsh. The Lords of the Marches claimed to provide silver spears, and support the canopy of purple silk at the coronation of Queen Eleanor, consort of King Henry III. The court of the Lord’s Marches was held at Ludlow, and the jurisdiction extended from Chester to Bristol. All the country between Offa’s Dyke and England was called the Marches, the Lords of which had the power of life and death in their respective courts. In every frontier manor a gallows was erected, and if any Welshmen came over the boundary they were taken up and hanged; and if any Englishman was caught on the Welsh side, he suffered the same fate. The houses were frequently
