What poem's fragment is often edited with Beowulf because it relates to the Finn episode?

The poem’s fragment is commonly called “The Fight at Finnsburg,” also known as the Finnesburg or Finnsburh Fragment.

The surviving text is roughly 50 lines of an Old English heroic poem. It opens as Hnæf, a Danish prince, sees armed attackers approaching Finn’s stronghold. Hnæf and his sixty retainers defend the hall for five days, but the fragment breaks off before the battle’s outcome.

Its importance comes from its close relationship to the Finn episode in Beowulf. In that episode, sung by Hrothgar’s scop, Hildeburh mourns her brother Hnæf and her son, who die in the conflict between Danes and Frisians. Hengest later avenges Hnæf by killing Finn. The two texts overlap but are not identical, and scholars debate details such as the identities of the attackers and the role of the Jutes.

The fragment’s original manuscript was lost; George Hickes preserved it in a transcript published in 1705. “Finnesburg Fragment” is the most common modern label, while “The Fight at Finnsburg” is an established editorial title.
