"You loved Siegfried better than Gunther," she declared. "Here are your girdle and ring which my husband gave to me." So saying, she displayed the girdle and ring which Siegfried had unwisely given her when he confided to her the story of Gunther's wooing.
Brunhild summoned Gunther to defend her, and he sent for Siegfried. The latter publicly swore that his wife had not told the truth and that Brunhild had never loved him or he her.
"This quarrel is disgraceful," he said. "I will teach my wife better manners for the future." Gunther promised to do likewise.
The guests departed, but Brunhild still smarted from the insult and longed for revenge. Hagen, finding her in tears, undertook to avenge her. He continually reminded Gunther of the insult his wife had received. The king at first paid no attention to the insinuations, but at last he consented to an assault on Siegfried.
He asked the great hero to help him in a war which he pretended his old enemy Ludeger was about to bring upon him. Siegfried consented, and Kriemhild, because she loved her husband very deeply, was much troubled. In her distress she confided to Hagen that Siegfried was invulnerable except in one spot, between the shoulder blades, where a lime leaf had rested and the dragon's blood had not touched him.
"Never fear," said Hagen, "I myself will help to protect him. You sew a tiny cross on Siegfried's doublet, just over the vulnerable spot, that I may be the better able to shield him."
Kriemhild promised to obey his instructions, and Hagen departed, well pleased, to carry the news to Gunther.
At last the day came for Siegfried to leave his queen. He talked to her and comforted her and kissed her rosy lips.
"Dear heart," he said, "why all these tears? I shall not be gone long."
But she was thinking of what she had told Hagen, and wept and wept and would not be comforted.
