Hitherto the Hakon-Blue-tooth disturbances in Norway had amounted to but little. King Greyfell, a very active and valiant man, has constantly, without much difficulty, repelled these sporadic bits of troubles; but Greyfell, all the same, would willingly have peace with dangerous old Blue-tooth (ever anxious to get his clutches over Norway on any terms) if peace with him could be had. Blue-tooth, too, professes every willingness; inveigles Greyfell, he and Hakon do; to have a friendly meeting on the Danish borders, and not only settle all these quarrels, but generously settle Greyfell in certain fiefs which he claimed in Denmark itself; and so swear everlasting friendship. Greyfell joyfully complies, punctually appears at the appointed day in Lymfjord Sound, the appointed place. Whereupon Hakon gives signal to Gold Harald, "To Lymfjord with these nine ships of yours, swift!" Gold Harald flies to Lymfjord with his ships, challenges King Harald Greyfell to land and fight; which the undaunted Greyfell, though so far outnumbered, does; and, fighting his very best, perishes there, he and almost all his people. Which done, Jarl Hakon, who is in readiness, attacks Gold Harald, the victorious but the wearied; easily beats Gold Harald, takes him prisoner, and instantly hangs and ends him, to the huge joy of King Blue-tooth and Hakon; who now make instant voyage to Norway; drive all the brother under-kings into rapid flight to the Orkneys, to any readiest shelter; and so, under the patronage of Blue-tooth, Hakon, with the title of Jarl, becomes ruler of Norway. This foul treachery done on the brave and honest Harald Greyfell is by some dated about A.D. 969, by Munch, 965, by others, computing out of Snorro only, A.D. 975. For there is always an uncertainty in these Icelandic dates (say rather, rare and rude attempts at dating, without even an "A.D." or other fixed "year one" to go upon in Iceland), though seldom, I think, so large a discrepancy as here.
