The Chronicle of The Kings of Norway
Part 86 - Battle At Scarborough
When King Harald was clear for sea, and the wind became favourable, he sailed out into the ocean; and he himself landed in Shetland, but a part of his fleet in the Orkney Islands. King Harald stopped but a short time in Shetland before sailing to Orkney, from whence he took with him a great armed force, and the earls Paul and Erlend, the sons of Earl Thorfin; but he left behind him here the Queen Ellisif, and her daughters Maria and Ingegerd.
Then he sailed, leaving Scotland and England westward of him, and landed at a place called Klifland. There he went on shore and plundered, and brought the country in subjection to him without opposition. Then he brought up at Skardaburg, and fought with the people of the place. He went up a hill which is there, and made a great pile upon it, which he set on fire; and when the pile was in clear flame, his men took large forks and pitched the burning wood down into the town, so that one house caught fire after the other, and the town surrendered.
The Northmen killed many people there and took all the booty they could lay hold of. There was nothing left for the Englishmen now, if they would preserve their lives, but to submit to King Harald; and thus he subdued the country wherever he came. Then the king proceeded south along the land, and brought up at Hellornes, where there came a force that had been assembled to oppose him, with which he had a battle, and gained the victory.
