2. The Conquest of the West and North. 1067—1069.—In March 1067 William returned to Normandy. In his absence the Normans left behind in England oppressed the English, and were supported in their oppression by the two regents appointed to govern in William's name, his half-brother, Odo, Bishop of Bayeux, whom he had made Earl of Kent, and William Fitz-Osbern, Earl of Hereford. In some parts the English rose in rebellion. In December William returned, and after putting down resistance in the south-eastern counties, set himself to conquer the rest of England. It took him more than two years to complete his task. Perhaps he would have failed even then if the whole of the unconquered part of the country had risen against him at the same time. Each district, however, resisted separately, and he was strong enough to beat them down one by one. In the spring of 1068 he besieged and took Exeter, and subdued the West to the Land's End. When this had been accomplished he turned northwards against Eadwine and Morkere, who had declared against him. William soon frightened them into submission, and seized on York and all the country to the south of York on the eastern side of England. In 1069 the English of the North rose once more and summoned to their aid Svend, king of Denmark, a nephew of the great Cnut. Svend sent a Danish fleet, and the Danes were joined by Eadgar the Ætheling and by other English chiefs. They burnt and plundered York, but could do no more. Their great host melted away. The Danes went off with their booty to their ships, and the English returned to their homes. William found no army to oppose him, and he not only regained the lands which he had occupied the year before, but added to them the whole country up to the Tweed.
3. The Completion of the Conquest. 1070.—William was never cruel without an object, but there was no cruelty which he would not commit if it would serve his purpose. He resolved to make all further resistance impossible. The Vale of York, a long and wide stretch of fertile ground running northwards from the city to the Tees, was laid waste by William's orders. The men who had joined in the revolt were slain. The stored-up crops, the ploughs, the carts, the oxen and sheep were destroyed by fire. Men, women, and children dropped dead of starvation, and their corpses lay unburied in the wasted fields. Some prolonged life by feeding on the flesh of horses, or even of men. Others sold themselves into slavery, bowing their heads, as was said, in the evil days for meat. "Waste! waste! waste!" was the account given long afterwards of field after field in what had once been one of the most fertile districts in England. William's work of conquest was almost over. Early in 1070 he crossed the hills amidst frost and snow, and descended upon Chester. Chester submitted, and with it the shires on the Welsh border. The whole of England was at last subdued.
4. Hereward's Revolt and the Homage of Malcolm. 1070—1072.—Only one serious attempt to revolt was afterwards made, but this was no more than a local rising. The Isle of Ely was in those days a real island in the midst of the waters of the fens. Hereward, with a band of followers, threw himself into the island, and it was only after a year's attack that he was driven out. When the revolt was at its height, Eadwine and Morkere fled from William's court to join the insurgents. Eadwine was murdered by his own attendants. Morkere reached Ely, and when resistance was at an end was banished to Normandy. No man ever deserved less pity than these two brothers. They had never sought any one's advantage but their own, and they had been faithless to every cause which they had pretended to adopt. Before Hereward was overpowered, Malcolm, king of the Scots, ravaged northern England, carrying off with him droves of English slaves. In 1072 William, who had by that time subdued Hereward, marched into Scotland as far as the Tay. Malcolm submitted to him at Abernethy, and acknowledged him to be his lord. Malcolm's acknowledgment was only a repetition of the acknowledgment made by his predecessors the Scottish kings, to Eadward and Cnut (see pp. [63], [84]); but William was more powerful than Eadward or Cnut had been, and was likely to construe the obligation more strictly.
5. How William kept down the English.—William, having conquered England, had now to govern it. His first object was to keep the English in subjection.
(a) The Confiscation of Land.—In the first place he continued to treat all who had resisted him as rebels, confiscating their land and giving it to some Norman follower. In almost every district there was at least one Norman landowner, who was on the watch against any attempt of his English neighbours to revolt, and who knew that he would lose his land if William lost his crown.
(b) Building Castles.—In the second place William built a castle in every town of importance, which he garrisoned with his own men. The most notable example of these castles is the Tower of London.
