In "Norna-Gests þáttr", it is said that Sigurd Ring was very old when he sent his son-in-law, the son of Gandalf, to request the Gjukungs, Gunnar and Högne to pay tribute. This was promptly refused. The sons of Gandalf then asked Sigurd Ring to help them fight against the Gjukungs and their renowned ally Sigurd Fafnisbani. Sigurd Ring could not help them in person, as he was busy fighting against ravaging Curonians and "Kœnir". Battle was joined in Holstein but turned into a defeat for the Norse army, since Sigurd Fanisbane made the Norse champion Starkad flee in panic.
