According to the Finnesburg Fragment, the Danish prince Hnaef came with sixty followers to visit and spent the winter at the Finnburg. Finnburg was the fort of his brother-in-law Finn, king of the Frisians. There a fight started between the Frisians and the Danes. A battle took place that lasted for three days. The verses of the story that were found (which is thought to be a small part of the original work) do not explain why the fight started, nor do they give the outcome of the battle.
