Huon and Sherasmin met, but, recognizing each other after a few moments' struggle, they suddenly embraced, and, joining forces, slew the pagans and carried off Esclarmonde and Fatima.

They embarked upon a swift sailing vessel, and soon arrived at Rome, where Huon related his adventures to the Pope, who gave him his blessing.
As they were on their way to Charlemagne's court, Girard, a knight who had taken possession of Huon's estates, stole the golden casket from Sherasmin, and sent Huon and Esclarmonde in chains to Bordeaux.

Then, going to court, he informed Charlemagne that although Huon had failed in his quest, he had dared to return to France.

Charlemagne, whose anger had not yet cooled, proceeded to Bordeaux, tried Huon, and condemned him to death.

But just as the knight was about to perish, Oberon appeared, bound the emperor and Girard fast, and only consented to restore them to freedom when Charlemagne promised to reinstate Huon.
Oberon then produced the missing casket, revealed Girard's treachery, and, after seeing him punished, bore Huon and Esclarmonde off to fairyland.
