At least the Danes learnt this at Sherston, that Eadmund could hold his own against them.
So Ulf the jarl wandered all night in the wood, and came out of it on the hillside where Godwine was speaking to one of his father's shepherds.

And Godwine brought him, unknowing who he was, back to Berkeley.
Then maybe came into Wulfnoth's mind that rede of the witch of Senlac, that bade Godwine mind his sheep, and so find his place, or else this was part of the plan which had brought him into Wessex.
For he asked Ulf to take Godwine to Cnut, and find him a place in his court, and the jarl did so.

It was not until Godwine came to the ships that he knew who it was that he had guided, and they won him over, and he stayed.
Nor did I know.

I spoke with Ulf, asking him of the battle, and of Egil, and the like, for he was the earl's guest.

And I thought nothing of Godwine's guidance of a Dane to the ships, for the earl was no foe of Cnut.
