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. Mingling as his people did in East Anglia with the Christian Saxons there, he must have had opportunities for learning the nature of their tenets, and of contrasting its mild and beneficent teaching with the savage worship of the pagan gods. By far the greater proportion of his people followed their king's example; but the wilder spirits quitted the country, and under their renowned leader Hasting sailed to harry the shores of France. The departure of the more turbulent portion of his followers rendered it more easy for the Danish king to carry his plans into effect.
