Sidney Oldall Addy, The Hall of Waltheof — IV. The Bar Dike and Other Earthworks at Bradfield (1893)
“ The land descends from the Dike both to the north and south. It would seem then that the fosse and mound were intended to protect a piece of ground through which an inroad could be easily made, the nature of the ground at either end being itself a substantial protection. A mile to the north-west of Bar Dike, and running nearly parallel to it, is another entrenchment about three-quarters of a mile in length. This entrenchment runs in a straight course across a comparatively level moor and is divided at right angles by a stream. In this case the fosse is also on the northern side of the mound. ”
