According to some accounts, the besieging forces retired without having obtained possession of the fortress; but the more probable story, and that which rests on the better authority, is that Prince Henry was at length obliged to capitulate, and that he was deprived of all his estates. For two years he wandered about the Continent with a scanty escort and in great poverty. At length he obtained the government of the city of Domfront, and in that position he displayed much ability, and obtained considerable power in the surrounding country. Meanwhile (1091) Malcolm Canmore had invaded England, and had penetrated "even to Chester." William sent an army to oppose him, and, according to some authorities, also fitted out a naval force, which was overtaken by a storm on the Scottish coast and destroyed.[8] The two armies met somewhere on the borders of Scotland, but the impending conflict was prevented by the efforts of Robert of Normandy, who had returned with William to England, and Edgar Atheling. A treaty of peace was concluded, by which Malcolm rendered homage to Rufus, as he had done to William the Conqueror, and was permitted to retain certain lands in Northumberland, of which he had become possessed. Soon after (1093) Rufus gave directions for the building of a fortress at Carlisle, and having sent a number of English to inhabit the town, he bestowed on them many valuable privileges. This act, if not an infringement of the recent treaty with Malcolm, was at least a violation of the rights of that monarch. The earldom of Cumberland had been for centuries attached to the Scottish crown, and Malcolm demanded its restitution. A conference took place between the two kings, and Rufus having refused redress for the injury, Malcolm returned in haste to Scotland, and carried an army into Northumberland, burning and laying waste the country. Before Rufus could advance to meet him, the Scottish monarch had fallen into an ambush, and was killed, together with his eldest son, at Alnwick. It is related that when the news of the death of her husband and son was brought to Margaret, the Queen of Scotland, she bowed her head beneath the stroke, and died within four days afterwards. [Illustration: GREAT SEAL OF WILLIAM II.] William, after his return from Carlisle, fell sick at Gloucester; and being oppressed with the recollection of his many crimes, and probably deriving little comfort from the ghostly ministrations of Flambard, he gave signs of repentance, and promised on his recovery to amend his life. The repentance, however, passed away with the danger, and he is represented as having become from this time more cruel and debauched than before.
