Thank you for selecting information on the Debenham Auxiliary Unit Patrol
and their Operational Base in Suffolk. The info and images below have been supplied by Aux researchers Evelyn Simak
and Adrian Pye.
The patrol formed part of No 3 Group North Suffolk which also included
Saxmundham (aka Carlton) Patrol
Wickham Market (aka Little Glemham) Patrol – codename
Stratford St Andrew Patrol
Leiston Patrol – codename “Seamew”
Easton Patrol and Peasenhall Patrol
Group CO: Capt George Scott-Moncrieff *
2nd Lt LWO Turner
Lt TH Denny (Later Major), Barkwith House, Leiston
George Scott-Moncrieff was Group Commander for North and South Suffolk. He lived at Orchard Close, Hacheston
near Framlingham during his AU service. His father was Lt Col George Kenneth Scott-Moncrieff of the Royal
Engineers, awarded Knight Commander in 1901 for service in India. Capt Scott-Moncrieff was one of the early AU COs
along with Andrew Croft, Nigel Oxenden, Captain Peter Fleming and Billy Beyts, all appointed by
Colin McVean Gubbins. Info: Stephen Lewins
It is currently unknown when the patrol was formed.

The OB site is located within the last section of the Suffolk Light Railway line which ends here, at Little
London Hill, north-west of Debenham. This section of the long-diused railway line is an overgrown embankment and
The OB appears to have collapsed. The central section is presumably intact but is inaccessible.
The main chamber measures 12 x 9ft with flat roof of corrugated sheeting supported by sections of railway
tracks. There was a drop down entrance shaft which has collapsed. The emergency exits course can clearly be seen in
the ground, presenting as an approx 6m long gully.
The OB is orientated N/S.
The site is listed on DoB (recorder: Will Ward) as an AU Observation Post; condition and building materials
unknown; built in 1940/41. DoB site reference: S0009926.
According to information compiled at the BRO Museum at Parham, this was not
an OP but rather the OB of Debenham Patrol, “located in an earth embankment of the extension to the mid-Suffolk
We were able to establish, and to confirm by personal interview of one of the patrol members, that the structure
was indeed an Operational Base.
The structure was dug into the embankment (from the top down), which follows a roughly north-south course. It
has collapsed, apparently quite some time ago. A depression, about 2m deep at the deepest end, can be seen at its
northern end, where the entrance shaft once would have been.
Corrugated sheeting has been arranged to form an open square at ground level above the structure’s north-eastern
corner. We don’t believe that the sheets are in their original position as they do stand about 1.20m high above the
surrounding ground and would easily have been spotted from a distance.
According to Reverend John Pretyman-Waller (son of patrol leader Reverend Trevor Waller) the OB consisted of two
chambers that were accessed by a drop-down shaft between the two. Both chambers had flat roofs.
A general overview of the site
Two images above show the main collapsed chamber
Other physical remains nearby: Corrugated sheeting, some with nails still adhering to it,
presumably where it was fastened to timber bracing. Two sections of railway tracks supporting the roof (presumably
there are more still in situ underground)
Sections of railway line supporting the roof
The 12ft long main chamber appears to have had a flat roof. At the bottom of the depression much of the
corrugated sheeting forming the roof is still in situ, as are two (still visible, perhaps more covered under soil)
of the sections of railway track that supported it.
Nails are still attached to parts of the upper rim of the corrugated sheeting, where we believe it would have
originally been affixed to a timber frame that over time would have rotted away. We did not see any remains of
The central and southern parts of the structure appear to still be intact (or perhaps less deeply collapsed than
the northern end) because the ground level here is about 60 cm higher.
Remains of emergency escape passage
At its southern end, a pronounced approx 6 metres long gully is leading away from the site, down the west side
of the embankment. We believe that it denotes the course of the emergency escape passage. The emergency escape
opening would have been at the southern end.
Sten or Thompson submachine guns, Fairbairn-Sykes fighting knives and .38 revolvers plus a variety of
explosives, detonators and fuses would have been standard issue.
