The wide fosse, or hollow, on the northern side is a noteworthy feature, and may have accommodated the huts of the defenders. Three entrances may have existed, but one appears modern, and there were possibly only two. The southern was ' well guarded, and seems only to have admitted of approach in single file from each side, with a triangular val- lum, hollowed out to receive special guardians of the entrance.'^' The position commands the south for about a mile, at other points only about half a mile ; but the view there of distant hills gives support to the opinion that Bach Camp was one of a series of early defensive works within signalling distance, as there are several other important fortresses within lo miles of Kimbolton. As a writer in the Transactions of the Woolhope Field Club, already quoted, says : — The more the strength of this position is considered, and the vast labour taken to fortify it, especially with the stockade in addition, the more probable it seems that it was occupied for some considerable time, and was rather a British fortified village or town than a simple encampment.
