Reading edition
Chron. 628. “Her Cynegils and Cwichelm gefuhtan wið Pendan æt Cirenceastre and geþingodon þa.” This I take to mean a cession of territory, most probably of the north-western conquests of Ceawlin. Oxfordshire and Buckinghamshire must have been kept longer, as appears from the position of Dorchester as originally a West-Saxon bishopric.
