[Sidenote:  Beda. lib. 3. ca. 1.  OSRIKE KING OF DEIRA.] After it was knowne that Edwin was slaine in battell (as before ye haue heard) Osrike the sonne of his vncle Elfrike tooke vpon him the rule of the kingdome of Deira, which had receiued the sacrament of baptisme by the preaching and vertuous instruction of Pauline.  But [Sidenote:  Eaufrid king of Bernicia.] the other kingdome of Northumberland called Bernicia, Eaufride the son of Edelferd or Edelfride, tooke vpon him to gouerne.  This Eaufride during the time of Edwins reigne, had continued in Scotland, and there being conuerted to the Christian faith was baptised.  But both these princes, after they had obteined possession of their earthlie kingdoms, did forget the care of the heauenlie kingdome, so that they returned to their old kind of idolatrie.  But almightie God did not long suffer this their vnthankefulnesse without iust punishment:  for first in the next summer, when Osrike had rashlie besieged Cadwallo king of the Britains, within a certeine towne, Cadwallo brake foorth vpon him, and finding him vnprouided to make resistance, slue him [Sidenote:  The two kings of Northumberland slaine.] with all his armie.  Now after this, whilest Cadwallo not like a conqueror gouerned the prouinces of the Northumbers, but like a tyrant wasted and destroied them, in sleaing the people in tragicall maner, he also slue Eaufride, the which with twelue men of warre came vndiscreetlie vnto him to sue for peace:  and thus within lesse than twelue moneths space both these runagate kings were dispatched.

[Sidenote:  OSWALD began his reigne in the yeare 635. Beda. lib.3. cap.3.] Then Oswald the sonne of Edelfred, and brother to the foresaid Eaufride was created king of the Northumbers, the sixt in number from Ida.  This Oswald after that his father was slaine, liued as a banished person a long time within Scotland, where he was baptised, and professed the Christian religion, and passed the flower of his youth in good exercises, both of mind & bodie.  Amongst other things he practised the vnderstanding of warlike knowledge, minding so to vse it as it might stand him in stead to defend himselfe from iniurie of the enimies that should prouoke him, and not otherwise.  Herevp[=o] Cadwallo king of the Britains made in maner no account of him:  for by reason that he had atchiued such great victories against the Englishmen, and hauing slaine their two kings (as before is expressed) he ceassed not to proceed in his tyrannicall dooings, reputing the English people for slouthfull, and not apt to the warre, boasting that he was borne to their destruction.  Thus being set vp in pride of courage, he feared no perils, but boldlie (without considering at all the skilfull knowledge which Oswald had sufficientlie learned in feates of war) tooke vpon him to assaile the foresaid Oswald, that had brought an armie against him, and was encamped in a plaine field neere vnto the wall which the Romans had builded in times past against the inuasion of Scots and Picts.
