Meanwhile the Franks and Burgundians had thrown off the yoke of the Huns, and Etzel did not dare to enforce it in the then condition of affairs. Hagen one day found out what had chanced, and, according to one account, he made his escape to his own people, but, according to another, was sent home loaded with honours. But Etzel did his best to keep Walter with him, for he knew his bravery and worth. Once when the king returned with his warriors from conquering an invading horde, he gave a great feast, and asked Hildegunde to sing him a song. The maiden complied, and sang about her old home and her mother, and how she trusted to return to them once more, when the hero came for whom she waited. Etzel did not take in the sense of her song, as she had expected; he had raised the wine-cup to his lips too often for that. But Queen Helche understood, and determined to watch Walter and the maiden, lest they should fly together. Walter, too, had understood the meaning of the song, and soon found an opportunity of arranging matters with Hildegunde regarding their flight. “Do not sleep to-night,” he whispered one evening, “but slip into the treasure-chamber, and take as much gold and silver as you can carry out of the seventh chest; it is part of the tribute money that your father and mine paid the Huns long ago. Put the money you have taken in two caskets, and bring them down to the hall. You will find me waiting for you at the gate with two saddled horses. We shall be gone a long time before the drunken Huns find out that we have escaped them.” [Illustration: WALTER AND HILDEGUNDE HALT IN THE FOREST.] They carried out Walter’s plan in every particular, and made their way to Bechelaren first, then to the Rhine, and finally to the mountains of Wasgengau (Vosges), in the highest of which, the Wasgenstein, they found a cave with such a narrow entrance that one man could there defend himself against an army. Walter wished to rest awhile, for he had had but little sleep during their long and toilsome journey, so he asked the maiden to keep watch, lest a sudden attack should be made upon them. He had not been long asleep when Hildegunde saw the sheen of armour in the distance. She wakened the hero, telling him that the Huns were upon them.
