William Rufus was not liked better in Northumbria than his father had been, and Robert Mowbray, Earl of Northumbria, had especial reason to dislike him, on account of his appropriation of the forest lands. He was a powerful chief, possessing two hundred and eighty manors, but he did not attend the Court. This displeased William, who sent forth a decree that every baron who did not attend the festival at Whitsuntide should be outlawed. The Earl paid no attention to this; and as he was engaged with other nobles in a conspiracy to dethrone William, the monarch brought his army into Northumbria, besieged and took the fortress at Newcastle, went on to Tynemouth, and then to Bamborough Castle, to which the Earl had escaped. This castle was impregnable, but the Earl was decoyed from it, and after going again to Tynemouth, he was wounded and taken prisoner. But William coveted the Castle of Bamborough, which was still held by the wife of the Earl. He, Mowbray, was taken to an eminence in front of the castle, while the Normans demanded parley with the Countess. She, to save her husband from having his eyes put out before her face, surrendered the castle to them, and the Earl was taken to the dungeons of Windsor Castle, and kept there for thirty years. In the year 1094 the little Island of Lindisfarne, or Holy Island, had built upon it a beautiful church and priory, for the Normans introduced a very superior style of architecture. Edward, one of the monks of Holy Island, was rich enough to undertake this work. It is said by an imaginative or credulous historian, that St. Cuthbert still worked miracles there. "The crowds of thirsty labourers, who had passed over to the island with materials for the new building, were, by Edward's interest with St. Cuthbert, enabled for a whole day to drink from a cup which was never once replenished by mortal hand. And multitudes were fed by this same Edward without materials." During the reign of Henry the First a bridge was built at Durham, the ruins of Hexham were restored, a Leper Hospital was built at Newcastle, and Northumberland and Durham were generally enriched. In Stephen's reign, David, King of Scotland, fought a battle with the English king in Northumberland; and, indeed, the history of the centuries, to the seventeenth, is full of the accounts of battles on the border with the English and Scotch, the Dukes of Northumberland being often at war with the Scottish kings. The battles were frequently on a large scale, and the bloodshed was frightful, while the ill-will begotten on both sides of the border was most bitter. King John met the Scottish king on the borders in the year 1213, and then the two professed to be reconciled, but very little good came of it.
