releeuing and helping him out of danger, when he was cast off his horsse, he was mooued with such a fatherlie affection, that presentlie after they were made friends, the father pardoned his sonne all his former offenses, and therevpon found him euer after more tractable and obedient than before. [Sidenote: An. Reg. 14. 1080.] After this battell, king William being thus accorded with his sonne, [Sidenote: _Simon Dunel._] returned with him into England, and immediatlie sent him against Malcolme king of Scotland, who hauing broken the truce in time of the trouble betwixt king William and his sonne, had doone much hurt by forraies vpon the English borders, wasting all Northumberland euen to the riuer of Tine. Howbeit, when he heard that Robert approched with his armie towards him, he retired into Scotland. [Sidenote: The foundation of New castell upon Tine, which before that season was called Moncaster.] Robert Curthuze then lodged with his armie vpon the banks of the riuer of Tine, where he began the foundation of a castell, whereof the towne Newcastell did after take both beginning and name, for before this season it was called Moncaster. About the same time, Odo the bishop of Bayeux was sent to Northumberland, to reuenge the death of Walkher bishop of Durham, whom not long before the people of Northumberland had slaine in a tumult. [Sidenote: _Simon Dun._] The occasion of his death grew by the death of one Liulfus, a noble man of those quarters, and déerelie beloued of the people, bicause he was descended of honorable parentage, and had married the ladie Algitha daughter vnto earle Alered, and sister to Alfleda the mother of earle Walteof.
