King Olaf sailed to Friesland, and lay under the strand of Kinlimma in dreadful weather.  The king landed with his men; but the people of the country rode down to the strand against them, and he fought them.  So says Sigvat:—

"Under Kinlimma's cliff,
This battle is the fifth.
The brave sea-rovers stand
All on the glittering sand;
And down the horsemen ride
To the edge of the rippling tide:
But Olaf taught the peasant band
To know the weight of a viking's hand."

The king sailed from thence westward to England.  It was then the case that the Danish king, Swend Forked Beard, was at that time in England with a Danish army, and had been fixed there for some time, and had seized upon King Ethelred's kingdom.  The Danes had spread themselves so widely over England, that it was come so far that King Ethelred had departed from the country, and had gone south to Valland.  The same autumn that King Olaf came to England, it happened that King Swend died suddenly in the night in his bed; and it is said by Englishmen that Edmund the Saint killed him, in the same way that the holy Mercurius had killed the apostate Julian...
