This year went the army about Devonshire into Severn- mouth, and equally plundered the people of Cornwall, North-Wales, and Devon. Then went they up at Watchet, and there much evil wrought in burning and manslaughter. Afterwards they coasted back about Penwithstert on the south side, and, turning into the mouth of the Tamer, went up till they came to Liddyford, burning and slaying everything that they met. Moreover, Ordulf's minster at Tavistock they burned to the ground, and brought to their ships incalculable plunder. This year Archbishop Elfric went to Rome after his staff.
