King Egbert hauing got this victorie, was aduanced into such hope, that he persuaded himselfe to be able without great adoo to ouercome the residue of his neighbours, whose estates he saw plainlie sore weakened and fallen into great decaie. Herevpon before all other, he determined to assaile Edelvulfe king of Kent, whome he knew to be a man in no estimation amongest his subiects. A competent armie therefore being leuied, he appointed his sonne Ethelwulfe & Alstan [Sidenote: Alstan bishop of Shireborn a warrior.] bishop of Shireborne, with earle Walhard to haue the conduct therof, and sent them with the same into Kent, where they wrought such maisteries, that they chased both the king and all other that would not submit themselues, out of the countrie, constreining them to [Sidenote: The conquests of the Westsaxons.] passe ouer the Thames. And herewith the Westsaxons following the victorie, brought vnder subiection of king Egbert the countries of Kent, Essex, Southerie, and Sussex. The Eastangles also about [Sidenote: _Henr. Hunt._] the same time receiued king Egbert for their souereigne Lord, and comforted by his setting on against Bernulfe king of Mercia, inuaded the confines of his kingdome, in reuenge of displeasures which he had doone to them latelie before, by inuading their countrie, and as it [Sidenote: Bernulf king of Mercia slaine.] came to passe, incountring with the said Bernulfe which came against them to defend his countrie, they slue him in the field. Thus their minds on both parts being kindled into further wrath, the Eastangles eftsoones in the yeare following fought with them of Mercia, and ouercame them againe, and slue their king Ludicenus, who succéeded Bernulfe in that kingdome, with 5 of his earles. The state of the kingdome of Mercia being weakened, Egbert conceiued an assured hope of good successe, & in the 27 yeare of his reigne, made an open inuasion into the countrie, and chasing Whitlafe king of Mercia (that succéeded Ludicenus) out of his estate, conquered the whole kingdome of the Mercies. But yet in the yéere next following, or in the third yeare after, he restored it againe to Whitlafe, with condition, that he should inioy the same as tributarie to him, and acknowledge him [Sidenote: _Simon Dun._] for his supreme gouernour. The same yeare that Bernulfe king of [Sidenote: These were the Cornish men as is to be supposed.] Mercia was slaine by the Eastangles, there was a sore battell foughten at Gauelford, betwixt them of Deuonshire, and the Britains, in the which manie thousands died on both parts.
