After this submission Waltheof received Judith, one of the Conqueror's nieces, in marriage, became the father of two children, and, after the deprivation of Cospatrick, had his highest ambition gratified by being installed as Earl of Northumberland. In that capacity the Anglo-Dane lived in the closest friendship with Vaulcher of Lorraine, Bishop of Durham. Sitting with Vaulcher in the synods of his clergy, Waltheof humbly and obediently put in execution the decrees of the bishop for reforming religion within the diocese. Nor did he by such conduct lose the favour of the English. All appeared prosperous; and Waltheof, united to the king's niece, and occupying his father's seat, enjoyed the favour of the Conqueror without having forfeited his popularity with the vanquished, when the conspiracy of Norwich, for which he cannot be considered to have been responsible, involved him in ruin and cost him his life. On that day, when Norman counts, Saxon thanes, and Welsh chiefs assembled at Norwich to celebrate the marriage of Ralph de Gael with the daughter of William Fitzosborne, conspicuous, by his high head and gigantic stature appeared Waltheof, the Anglo-Dane. It would seem, however, that Waltheof took no part in the abuse lavished upon the uncle of his wife. But when the tumult was at the loudest, one of the Norman earls, rising suddenly, hushed the assembly to silence, and solemnly appealed to Waltheof to take part in the revolt. "Brave man," said the earl, with that eloquence for which the Normans were so famous, "this is a great moment for your country; this is, for you, the hour of vengeance and fortune. Join us, and we will re-establish the kingdom of England in every respect as it was in the time of King Edward. One of us three shall be king, the other two shall command under him, and all lordships shall be held of us. William is occupied beyond sea; we are satisfied that he will not again cross the Channel. Now, brave warrior, adopt our plan; 'tis the best for thee, for thy family, and for thy crushed and fallen nation." "It is! it is!" shouted the guests in chorus. But Waltheof hesitated and remained silent. Warned by former failures, and with the fate of Edwin and Morkar before his mind's eye, he shrunk from embarking in an enterprise which he felt must terminate in disaster. At length he allowed himself so far to be drawn into the league that he promised secrecy. It would seem, however, that Waltheof did not keep his word. The secret preyed on his mind. Uneasy, restless, and sleepless, he revealed the conspiracy first to his wife, Judith, and then to Archbishop Lanfranc. It is even said that he was persuaded by the primate to repair to Normandy and warn the Conqueror.
