[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. He, inspired by her presence, slew all except Gunther and Hagen, who beat a hasty retreat. They did not return to Worms, however, but lay in ambush beside the road, and when Walther and Hildegunde passed by they attacked the former with great fury. In spite of the odds against him, the poem relates that Walther triumphantly defeated them both, putting out one of Hagen's eyes and cutting off one of Gunther's hands and one of his feet. The conflict ended, Hildegunde bound up the wounds of all three of the combatants, who then sat down to share a meal together, indulged in much jocularity about their wounds, and, parting amicably, sought their respective homes. Walther and Hildegunde were next joyously welcomed by their relatives, duly married, and reigned together over Aquitaine for many a long year. In the mean while Dietrich had been engaged in warring against Waldemar, King of Reussen (Russia and Poland), in behalf of Etzel, who, however, forsook him in a cowardly way, and left him in a besieged fortress, in the midst of the enemy's land, with only a handful of men. In spite of all his courage, Dietrich would have been forced to surrender had not Rüdiger of Bechlaren come to his rescue. By their combined efforts, Waldemar was slain, and his son was brought captive to Susat. [Sidenote: Dietrich and Queen Helche.] Dietrich and his noble prisoner were both seriously wounded; but while Queen Helche herself tenderly cared for the young prince of Reussen, who was her kinsman, Dietrich lay neglected and alone in a remote part of the palace. The young prince was no sooner cured, however, than he took advantage of Etzel's absence to escape, although Helche implored him not to do so, and assured him that she would have to pay for his absence with her life.
