Note 134
At Beran-birig, or Barbury-castle, near Marlborough. The Saxon Chronicle assigns the name and date. Camden (Britannia, vol. i. p. 128) ascertains the place; and Henry of Huntingdon (Scriptores post Bedam, p. 31 4) relates the circumstances of this battle. They are probable and characteristic; and the historians of the twelfth century might consult some materials that no longer exist.
