Athelstan had set Earl Alfgeir and Earl Gudrek to rule Northumberland and defend it from the Scots. But Olaf of Scotland came south with his mighty host; there was a fierce battle; Earl Gudrek was slain and Earl Alfgeir fled. When Athelstan heard of the triumph of Olaf, he began at once to march northward with all the men he could get together; but he was yet young, and some of the treacherous earls, hearing that Olaf had so far been victor, deserted King Athelstan. Chief among these traitors were Earl Hring and Earl Adils, who should have been in the very front of the English army, but who basely went over to the Scots. Thus Olaf’s host became exceeding great, greater by far than the English army. Then Athelstan called together his captains and his counsellors; Egil was there, and heard all the grave talk as to what should be done. At last a plan was made that all thought good, and this is what followed. First, messengers were sent to King Olaf, saying that King Athelstan would meet him in fair fight at Vinheath by Vinwood, in Northumberland, where he would mark out the field of battle with rods of hazel. He who won the battle should be king over all England. The armies should meet a week hence, and whichever was first on the ground should wait a week for the other. King Olaf should bide quiet, and not harry the land till the battle was ended. North of the heath was a town; there King Olaf stayed, for there he could best get provisions for his army. But some of his men he sent to the heath, to view it. The hazel-poles were already set up on the large level plain. A river was on one side, and a wood was on the other. And where river and wood were nearest to one another, there King Athelstan’s tents were pitched.
