While the Danes were still in the camp a witenagemot or Saxon parliament was held at Wedmore.

At this Athelstan and many of the nobles and inhabitants of East Anglia were present, and the boundary of the two kingdoms was settled.

It was to commence at the mouth of the Thames, to run along the river Lea to its source, and at Bedford turn to the right along the Ouse as far as Watling Street.

According to this arrangement a considerable portion of the kingdom of Mercia fell to Alfred's share.
The treaty comprehended various rules for the conduct of commerce, and courts were instituted for the trial of disputes and crimes.

The Danes did not at once leave Mercia, but for a considerable time lay in camp at Cirencester; but all who refused to become Christians were ordered to depart beyond the seas, and the Danes gradually withdrew within their boundary.
Guthorn's conversion, although no doubt brought about at the moment by his admiration of the clemency of Alfred, had probably been for some time projected by him.
