Editing Vortigern (section)

===The ''Anglo-Saxon Chronicle''===
The ''[[Anglo-Saxon Chronicle]]'' provides dates and locations of four battles which Hengest and his brother Horsa fought against the British in the county of Kent.<ref name=Laycock/> Vortigern is said to have been the commander of the British for only the first battle; the opponents in the next three battles are variously termed "[[Celtic Britons|British]]" and "[[Welsh people|Welsh]]", which is not unusual for this part of the ''Chronicle''. The ''Chronicle'' locates the [[Battle of Wippedesfleot]] as the place where the Saxons first landed, dated 465 in ''Wippedsfleot'' and thought to be [[Ebbsfleet, Thanet|Ebbsfleet]] near [[Ramsgate]]. The year 455 is the last date when Vortigern is mentioned.

The annals for the 5th century in the ''Chronicle'' were put into their current form during the 9th century, probably during the reign of [[Alfred the Great]].<ref name=MS_xxi>{{cite book |last= Swanton|first= Michael|title= The Anglo-Saxon Chronicle|pages=xxi–xxviii |year= 1998|publisher= Routledge |location=New York; London |isbn=0-415-92129-5 |url=https://books.google.com/books?id=f8B4NAl2r48C&pg=PR19 }}</ref> The sources are obscure for the fifth century annals; however, an analysis of the text demonstrates some poetic conventions, so it is probable that they were derived from an oral tradition such as [[saga]]s in the form of [[epic poetry|epic poems]].<ref name=jones71>{{Cite book|last=Jones|first=Michael E.|title= The End of Roman Britain|year= 1988|publisher=Cornell University Press|location=Ithaca, New York|isbn=0-8014-8530-4|page=71 }}</ref><ref name=gransen>{{Cite book|last=Gransden|first=Antonia|title=Historical Writing in England c.550-c1307|publisher=Routledge and Kegan Paull|location=London|year=1974|isbn=0-7100-7476-X|pages=36–39}}</ref>

There is dispute as to when the material was written which comprises the ''Historia Brittonum'', and it could be later than the ''Chronicle''. Some historians argue that the ''Historia Brittonum'' took its material from a source close to the ''Chronicle''.
