Nevertheless, a plot was soon after formed to put Malcolm to death, and of this the chief author was a nobleman who frequented the court. Malcolm early became aware of the existence of the plot, but affected ignorance, till one day, when out hunting, he took the chief conspirator aside, and severely reproached him.

"But," said Malcolm, "here is a fit place and time to do that manfully which you have intended to do treacherously; and here draw your sword, if you dare."

The nobleman, however, fell on his knees, confessed his fault, asked forgiveness, and ever afterwards served his king faithfully.

It cannot be said that Malcolm Canmore, when seated securely on the Scottish throne, displayed any particular gratitude to his benefactors. Indeed, the nation under the protection of which he had found safety in the day of adversity, and by the aid of which he had gained his crown, had more than once strong reason to complain of his enmity and denounce his ingratitude. But it was chiefly in the third year after the landing of William the Norman that Malcolm offended. When the Northumbrians drew together at York, to make head against the Conqueror's power, Malcolm mustered an army to lead to their assistance. Ere he was ready to take the field, however, the Northumbrians were put down; but, unwilling to be baulked of carnage and plunder, he marched by way of Carlisle, which, with Cumberland, he then held from the English crown, into Northumberland, and let loose all the fury of his barbarous subjects on the land where he had found rest in his weariness and consolation in his despair.

The Scots proceeded with energy to the work of destruction and bloodshed. Cleveland was savagely overrun; Wearmouth was sacked; St. Peter's Church was burned; the banks of the Wear were ravaged without mercy; and everywhere the inhabitants were treated with barbarous cruelty. Able-bodied men and women were driven off captive, like flocks of sheep, and in such numbers, that, for many years after, there was scarcely a tenement in Scotland without English slaves of one sex or the other. Blood, meanwhile, flowed like water. Grandfathers and grandmothers, on the verge of the grave, and infants torn from their mothers' arms, were ruthlessly slaughtered. Warriors, calling themselves men and Christians, exhibited neither humanity nor religion. Never had Pagan Danes or Norwegians been guilty of such atrocities as were perpetrated on this memorable occasion.

One day, while the church of St. Peter was in flames, and while the Scots were revelling in carnage and cruelty, Malcolm, as he rode along and witnessed savage outrages which it is charitable to suppose he could not prevent, received intelligence that Edgar Atheling, with his mother Agatha, and his two sisters, Margaret and Christina—whom the chronicler describes as "comely young women"—were on board a ship in the harbour, waiting for a fair wind, but scarcely knew whither to steer their course. The tale of their distress appears to have touched the heart of Malcolm; he sent messages of kindness, invited them to repair to Scotland, and assured them that they might there reside in safety as long as they pleased. In their despair, the royal exiles grasped at this invitation, and the mariners steered for Scotland.

Accordingly, when Malcolm Canmore returned to his own dominions, he found that the heirs of Alfred and of Ironsides had sought refuge on the Scottish shores. The young king hastened to make their acquaintance; and the result was important in its influence on the destinies of England. The sweetness and piety of Margaret Atheling, endowed as she was with all the comeliness characteristic of Saxon women, produced a strange effect on the royal Scot, and he soon arrived at the conclusion that the opportunity of securing such a bride ought not to be neglected. A marriage was, in due time, celebrated; the Saxon Queen of Scots, by her precepts and example, exercised a softening and civilizing influence on her fierce husband and his savage subjects; their daughter Maude became the wife of Henry Beauclerc; and from their ancestress—the heiress of Henry and Maude, married to Geoffrey, the brave and accomplished Count of Anjou—the Plantagenets inherited royal Saxon blood, and that sympathy with the vanquished race which made them, when kings, the favourites and heroes of the English people.

William the Conqueror was not, of course, inattentive to what was passing in the north; nor, indeed, did Malcolm allow the Norman to overlook his existence. In 1073, the Scottish king gathered an army, and crossed the Border to vindicate the claim of his wife's family to the English crown. By this time, however, William had put the Saxons throughout England under his feet, and resolved to bring Malcolm to reason by demanding the extradition of those who had taken refuge in Scotland.

With this object William placed himself at the head of his army, and, for the first time, crossed the Tweed. Not inclined to try conclusions with an antagonist so formidable, Malcolm presented himself to the Conqueror at a place near the frontier, which is supposed to have been Berwick; and, though declining to surrender the Saxon emigrants, "met King William in a peaceful attitude, touched his hand in sign of friendship, promised that William's enemies should be his also, and freely acknowledged himself his vassal and liegeman."
