The "Anglo-Saxon Chronicle" stated in 815 (adjusted date) "and in this year king Ecgbryht raided in Cornwall from east to west." and thenceforth apparently held it as a ducatus or dukedom annexed to his regnum or kingdom of Wessex, but not wholly incorporated with it. The "Anglo-Saxon Chronicle" states that in 825 (adjusted date) a battle took place between the Wealas (Cornish) and the Defnas (men of Devon) at Gafulforda. In the same year Ecgbert, as a later document expresses it, "disposed of their territory as it seemed fit to him, giving a tenth part of it to God." In other words, he incorporated Cornwall ecclesiastically with the West Saxon diocese of Sherborne, and endowed Eahlstan, his fighting bishop, who took part in the campaign, with an extensive Cornish estate consisting of Callington and Lawhitton, both in the Tamar valley, and Pawton near Padstow.
