Of course these successes were owing to treachery, and not to valor, and Dietrich, to obtain the release of Hildebrand and a few other faithful followers, who had fallen into the enemy's hands, was forced to surrender Bern and go off into exile.
As he had thus sacrificed his kingdom to obtain their freedom, it is no wonder that these men proudly accompanied him into banishment.

They went to Susat, where they were warmly welcomed by Etzel and Helche (Herka), his wife, who promised to care for Diether, Dietrich's brother, and have him brought up with her own sons.
There were in those days many foreigners at Etzel's court, for he had secured as hostages Hagen of Tronje, from the Burgundians; the Princess Hildegunde, from the Franks; and Walther von Wasgenstein from the Duke of Aquitaine.
[Sidenote: Walther of Aquitaine and Hildegunde.] During the twenty years which Dietrich now spent in the land of the Huns fighting for Etzel, peace was concluded with Burgundy and Hagen was allowed to return home.

Walther of Aquitaine (or von Wasgenstein), whose adventures are related in a Latin poem of the eighth or ninth century, had fallen in love with Hildegunde.
Seeing that Etzel, in spite of his promises to set them both free, had no real intention of doing so, he and his ladylove cleverly effected their escape, and fled to the Wasgenstein (Vosges), where they paused in a cave to recruit their exhausted strength.

Gunther, King of Burgundy, and Hagen of Tronje, his ally, hearing that Walther and Hildegunde were in the neighborhood, and desirous of obtaining the large sum of gold which they had carried away from Etzel's court, set out to attack them, with a force of twelve picked men.

But Hildegunde was watching while Walther slept, and, seeing them draw near, warned her lover.
