Who did liudeger believe captured his brother

To Gunther's land were come the messengers his foes had sent. Men asked the strangers for their tidings and bade them hie them soon to court unto King Gunther. The king gave them greeting fair; he spake: "Be ye welcome . I have not heard who sent you hither, but let that now be told." So spake the right good king. But they feared full sore King Gunther's warlike mood.

"Will ye, O King, permit that we tell the tales we bring, then we shall not hold our tongue, but name to you the lordings who have sent us hither: Liudegast and Liudeger; they would march upon this land. Ye have earned their wrath, indeed we heard that both lords bear you mortal hate. They would harry at Worms upon the Rhine and have the aid of many a knight; that may ye know upon our faith. Within twelve weeks the journey must befall. And ye have aught of good friends, who will help guard your castles and your lands, let this soon be seen. Here shall be carved by them many a helm and shield. Or would ye parley with them, let messengers be sent. Then the numerous bands of your mighty foes will not ride so near you, to give you pain of heart, from which full many a lusty knight and a good must die."

"Now bide a time," spake the good king, "till I bethink me better; then ye shall know my mind. Have I aught of trusty men, I will not withhold from them these startling tales, but will make complaint thereof unto my friends."

To Gunther, the mighty king, it was loth enow, but in his heart he bare the speech in secret wise. He bade Hagen be fetched and others of his men, and sent eftsoon to court for Gernot. Then came the very best of men that could he found. The king spake:

"Men would seek us here in this our land with mighty armies, now make ye wail for that."
