Anglo-Saxon Chronicle. 978. This year was King Edward (age 16) slain, at eventide, at Corfe-gate [Map], on the fifteenth day before the calends of April. And he was buried at Wareham [Map] without any royal honour. No worse deed than this was ever done by the English nation since they first sought the land of Britain. Men murdered him but God has magnified him. He was in life an earthly king-he is now after death a heavenly saint. Him would not his earthly relatives avenge-but his heavenly father has avenged him amply. The earthly homicides would wipe out his memory from the earth-but the avenger above has spread his memory abroad in heaven and in earth. Those, Who would not before bow to his living body, now bow on their knees to His dead bones. Now we may conclude, that the wisdom of men, and their meditations, and their counsels, are as nought against the appointment of God. In this same year succeeded Ethelred Etheling (age 12), his brother, to the government; and he was afterwards very readily, and with great joy to the counsellors of England, consecrated king at Kingston [Map]. In the same year also died Alfwold, who was Bishop of Dorsetshire, and whose body lieth in the minster at Sherborn [Map].
