By these and the like arbitrary methods having amassed great treasures, and finding all things quiet at home, he raised a powerful army to invade his brother in Normandy; but upon what ground or pretext, the writers of that age are not very exact; whether it were from a principle frequent among unjust princes, That old oppressions are best justified by new; or, whether having a talent for sudden enterprises, and justly apprehending the resentments of Duke Robert, he thought it the wiser course to prevent injuries than to revenge them. In this expedition he took several cities and castles from his brother, and would have proceeded further, if Robert had not desired and obtained the assistance of Philip King of France, who came with an army to his relief. King William not thinking it safe or prudent to proceed further against his enemy supported by so great an ally, yet loth to lose the fruits of his time and valour, fell upon a known and old expedient, which no prince ever practised oftener, or with greater success, and that was, to buy off the French King with a sum of money. This had its effect; for that prince not able to oppose such powerful arms, immediately withdrew himself and his forces, leaving the two brothers to concert the measures of a peace.
This was treated and agreed with great advantages on the side of King William; for he kept all the towns he had taken, obliged his brother to banish Edgar Atheling out of Normandy, and, for a further security, brought over with him to England the Duke himself to attend him in his expedition against Malcolm King of Scotland, who during his absence had invaded the borders. The King having raised great forces both by sea and land, went in person to repel the inroads of the Scots: but the enterprise was without success; for the greatest part of his fleet was destroyed by a tempest, and his army very much diminished by sickness and famine, which forced him to a peace of little honour; by which, upon the condition of homage from that prince, the King of England agreed to deliver him up those twelve towns (or manors) in England which Malcolm had held under William the Conqueror; together with a pension of twelve thousand marks.
At this time were sown the seeds of another quarrel between him and Duke Robert, who soliciting the King to perform some covenants of the last peace, and meeting with a repulse, withdrew in great discontent to Normandy.
King William, in his return from Scotland, fell dangerously sick at Gloucester, where, moved by the seasonable exhortations of his clergy, or rather by the fears of dying, he began to discover great marks of repentance, with many promises of amendment and retribution, particularly for his injuries to the Church. To give credit to which good resolutions, he immediately filled several vacant sees, giving that of Canterbury to Anselm, a foreigner of great fame for piety and learning. But as it is the disposition of men who derive their
