In the meantime, affairs had not run smoothly in England. We may easily guess that William's lieutenants, especially his brother, had not failed on the side of too great gentleness in carrying out his directions to secure the land with garrisons and castles. In various places unconnected with one another troubles had broken out. In the north, where Copsi had been made Earl of Northumberland, an old local dynastic feud was still unsettled, and the mere appointment of an earl would not bring it to an end. Copsi was slain by his rival, Oswulf, who was himself soon afterward killed, but the Norman occupation had still to be begun. In the west a more interesting resistance to the Norman advance had developed near Hereford, led by Edric, called the Wild, descendant of a noble Saxon house. He had enlisted the support of the Welsh, and in retaliation for attacks upon himself had laid waste a large district in Herefordshire. Odo had had in his county an insurrection which threatened for a moment to have most serious consequences, but which had ended in a complete failure. The men of Kent, planning rebellion, had sent across the channel to Eustace, Count of Boulogne, who believed that he had causes of grievance against William, and had besought him to come to their aid in an attempt to seize the fortress of Dover. Eustace accepted the invitation and crossed over at the appointed time, but his allies had not all gathered when he arrived, and the unsteady character of the count wrecked the enterprise. He attacked in haste, and when he failed to carry the castle by storm, he retired in equal haste and abandoned the undertaking. William judged him too important a man to treat with severity, and restored him to his favour. Besides these signs which revealed the danger of an open outbreak, William undoubtedly knew that many of the English had left the country and had gone in various directions, seeking foreign aid. His absence could not be prolonged without serious consequences, and in December, 1067, he returned to England. [1] William of Poitiers, in Migne's Patrologia Latina, cxlix, 1258, and see F.
