The whole sequence of events is unaltered.
Offa's own part in the removal of the hapless young king is given entirely from the accounts of the chroniclers, and the characters of Quendritha the queen and her accomplice Gymbert are by no means drawn here more darkly than in their pages.

The story of her voyage and finding by Offa is from Brompton's Annals.
The first recorded landing of the Danes in Wessex, with which the story opens, is from the "Anglo-Saxon Chronicle;" the name of the sheriff, and the account of the headstrong conduct which led to his end, being added from Ethelwerd.

The exact place of the landing is not stated; but as it was undoubtedly near Dorchester, it may be located at Weymouth with sufficient probability.

For the reasons which led to the exile of Ecgbert, and to his long stay at the court of Carl the Great, the authority is William of Malmesbury.
The close correspondence between the Mercian and Frankish courts is, of course, historic--Offa seeming most anxious to ally himself with the great Continental monarch, if only in name.

The position of the hero as an honoured and independent guest at the hall of Offa would certainly be that assigned to an emissary from Carl.
With regard to the proper names involved, I have preferred to use modern forms rather than the cumbrous if more correct spelling of the period.
