Bede gives the date as 12 October in his Ecclesiastical History of the English People (book II, chapter 20), but the Anglo-Saxon Chronicle gives the date as 14 October. Bede also gives the year as 633; however, a question about what Bede considered the starting point of the years as he used them has raised the possibility that the battle may have actually taken place in 632.
