It happened that, after the execution of Waltheof at Winchester, the earldom of Northumberland was purchased from the Conqueror by Vaulcher, Bishop of Durham, and that his government was somewhat unsatisfactory. Vaulcher, indeed, appears to have been a learned, pious, and well-meaning man, and to have shown his respect for popular sentiment by the high consideration he paid to Liulf, a Saxon thane connected by marriage with the wife of Siward and with the mother of Cospatrick. But Leofwin, the bishop's chaplain and chief confidant, and Gislebert, a kinsman who acted as the bishop's deputy in administering the affairs of this province, regarded Liulf with envy and malice. After frequent exhibitions of ill-will, they conspired to murder Liulf; and Gislebert, entering the Saxon thane's house by night, put him and his family to the sword.
Vaulcher was naturally much enraged at this atrocity. Such, however, was his position that he was fain to pass over the crime, and even to continue his countenance to Leofwin and Gislebert. The Northumbrians, deeming that this was adding insult to injury, held nocturnal conferences, as in the time of Robert Comine, and were so evidently bent on mischief, that Vaulcher recognised the necessity of doing something to allay the ferment. With this object he announced his intention of holding a court, and mediating between the relatives of Liulf on the one part and Leofwin and Gislebert on the other.
It was on the 14th of May, 1080, and at Gateshead, that Vaulcher met the Northumbrians. The bishop was attended by Leofwin and Gislebert, and about a hundred men of foreign birth; and the Northumbrians, all secretly armed, were headed by Eadulf, surnamed Rus, a great-grandson of Earl Uchtred, and a connexion by marriage of Liulf. Knowing the French language, Eadulf acted as spokesman, and conferred with the bishop on the business of the day, and then stated that he must consult his followers as to the terms proposed. But instead of doing so, he cried out—"Short reed, good reed, slay ye the bishop;" and the Northumbrians, who had come with weapons concealed under their clothes, instantly brandished them in the air. In order to encourage his followers, Eadulf struck down Vaulcher with his own hand; and the Northumbrians, rushing on the bishop's attendants, slaughtered them without mercy. Only two servants, men who were natives of England, escaped the massacre.
News of this outrage at Gateshead was carried to Odo. The Bishop of Bayeux smiled grimly, and, girding on his armour, promptly marched northward to punish the perpetrators of the murder. But, meanwhile, the Northumbrians had marched to Durham, attacked that city, and, after finding their efforts vain, dispersed in all directions. Eadulf and the ringleaders fled the country; and, when Odo's approach was announced, few remained at home except those who had taken no part in the insurrection.
But Odo had ridden northward indulging in visions of carnage and plunder; and he was not to be baffled in his expectations by considerations of justice. Aware that the murderers of the bishop had fled, he avenged their crime on the whole province, ravaged the country, executed many of the inhabitants, mutilated others in the most revolting manner, plundered the church at Durham of the sacred ornaments which Bishop Eghelwin had formerly saved by removal to Holy Island, and gained a high reputation among the most disreputable class of the Norman conquerors, who proudly described him as "one of the greatest quellers of the English."
On learning what had occurred in Northumberland, William was doubtless surprised to hear of his brother acting so like a madman. But his astonishment was still greater when he learned that Odo was on the point of leaving England and proceeding to Italy. In fact, the queller of the Northumbrians, relying on some prediction of an Italian soothsayer that the next Pope should be named Odo, had bought a palace in Rome, and, in order to secure his election to the papal chair, was not only preparing to go thither, but had engaged his nephew, Hugh Le Loup, Earl of Chester, and many other Norman knights and barons, to form his court.
The idea of Odo aspiring to the chair of St. Peter proved in the highest degree displeasing to William. Sailing from Normandy without delay, he contrived to intercept Odo off the Isle of Wight. Assembling a council of Norman barons, he presented Odo to them, and accused him of having abused his power as judge and earl.
"This man," explained William, "has despoiled churches; he has maltreated the Saxons to the danger of the common cause; and he has attempted to seduce and take with him beyond the Alps the warriors on whose fidelity the safety of the country depended. Consider these grievances," said William, in conclusion, "and tell me how I ought to act towards such a brother."
The barons looked at each other; but no one ventured to reply.
