As to the wretched Prince Alfred, he was stripped naked, tied to a horse and sent away into the Isle of Ely, where his eyes were torn out of his head, and where in a few days he miserably died.

Harold was now King all over England, though it is doubtful whether the Archbishop of Canterbury (the greater part of the priests were Saxons, and not friendly to the Danes) ever consented to crown him.

Crowned or uncrowned, with the Archbishop's leave or without it, he was King for four years: after which short reign he died, and was buried; having never done much in life but go a hunting.

He was such a fast runner at this, his favourite sport, that the people called him Harold Harefoot.
Hardicanute was then at Bruges, in Flanders, plotting, with his mother (who had gone over there after the cruel murder of Prince Alfred), for the invasion of England.

The Danes and Saxons, finding themselves without a King, and dreading new disputes, made common cause, and joined in inviting him to occupy the Throne.
