Research into this patrol and its training is ongoing. The information below is published from

The Richard's family were local builders and decorators.
The OB and nearby bomb store were located in Trewithen (locally known as Barteliver) Woods. Part of the vast
estate of Trewithen House, Trewithen (Barteliver) Woods are a very short distance from Old Hill , where many in the
patrol lived, and Bartilever Hill on the perimeter of the Parish.

Located and recorded by Phil Hadley.
The Fal runs along the bottom of the valley (north to south) with a small stream running into it at right angles
(west to east). The OB is in woodland - about 15m from the edge by the field. The field is north of the OB. The
site is at the top of a steep wooded slope up from the stream. From the edge of the woodland you had a view across
the field down onto the village. You would have been able to monitor traffic on the A390 from the edge of the
The depression in the ground where the OB would have been is still visible although someone seems to have tried
to make some kind of roofing for a den from the branches now fallen in it.There are two sheets of corrugated iron
by the depression.
The deepest part of the depression is about 5m by 3m but the shallow part of the depression extends another 8 or
9m by approx 3m. It is difficult to tell how much of the depression was the base. The 2 pieces of corrugated
sheeting are by the deeper part of the depression.
Orientation of OB: The depression runs east-west with the most likely spot for the entrance
being at the eastern end.
Other physical remains nearby: While Phil was recording the OB a local couple were able to
direct him to another area 45m uphill from the OB.
This much smaller site has two sheets of corrugated iron lying in situ with a third lying out on the ground. We
consider this could have been a bomb store.
Possible Bomb Store
Post/s: Currently unknown
Grampound now stands on the A390 which is a major route between Plymouth and Falmouth.
The footpath, known locally as the 'Roman Road' and 'Old Hill' (it leads to the Roman Fort of Carvossa) was once
the main road to Probus before it was re-routed in the 1960's to form part of the A390.
Grampound Bridge is a bridging point over the River Fal which one assumes would have had strategic importance.
