Blair 2003, p. 15 dates it to "c. 400–450" AD, whereas Tolkien 2006, p. 167 dates it to precisely 452 AD. Both suggestions depend on identifying Hengest in the Battle of Finnsburg with the founder of the Kingdom of Kent, an association which is uncertain.

Gwara 2008, p. 163, argues that Hengest is not Danish; and that "it seems certain that Hengest is the originary Germanic settler of Kent, as stated in Bede." The problem is a complex one. Gwara, Scott (2008), Heroic Identity in the World of Beowulf, BRILL, ISBN978-9004171701
Marsden 2004, p. 273. The identification of Hildeburh as the Frisian queen is a rarity in that it appears to be universally held despite the lack of direct evidence from the sources. Marsden, Richard (2004), The Cambridge Old English Reader, Cambridge University Press, ISBN9780521456128
Zocco 2007, p. 67, "in the most generally accepted reconstruction the first assault is from the part of the Frisians in a treacherous onslaught which excites the Danish strenuous defence". The term Frisian side avoids imputing specific responsibility to either Finn, Frisians, Jutes, or others. Zocco, Nicola (2007), "The Episode of Finn in Beowulf. Discharging Hengest"(PDF), Linguistica e Filologia, 24: 65–83
Zocco 2007, pp. 66–7. "It seems to be generally accepted that the Fragment reports facts which happened before those told in the Episode" Zocco, Nicola (2007), "The Episode of Finn in Beowulf. Discharging Hengest"(PDF), Linguistica e Filologia, 24: 65–83
