Historia ecclesiastica gentis Anglorum
Nearly all that is known of him is from Bede's "Historia ecclesiastica gentis Anglorum", which describes the invasion of the Isle of Wight by Caedwalla, a Wessex King, who, with merciless slaughter, endeavoured to destroy all the island's inhabitants and replace them with his own followers. Caedwalla had also vowed to give a quarter of the Isle of Wight to St. Wilfrid and the Church.
