I only had time to visit two of the barrows doted around the large Hatchet Moor / Beaulieu Heath area. The first was at SU345012, only 500m from the main B3055 road. It looks a bit ravaged, in a scrubby area populated by rabbits, and it trapped on two sides by old airfield roads. The barrow is about 25m diameter and 1.4m tall. The second is the Pudding Barrow, which already has an individual listing.
A forester accounted for the tumuli on Beaulieu Heath in this fashion:-- "We calls ut Saltpetre Bank. All these here mounds was throwd up by Uliver Crummle when he tuk the Farest; he and the Danes beat the English the fust time they ever was beat, and he druv the English into Wales."
