Plasterdown Camp
The history of the U.S Army Camp operated by the 115th Field Hospital Unit at Plasterdown (or Plaister Down) between Horrabridge (via Jordan Lane) and Whitchurch Common (Warren’s Cross) in WWII has been very well documented by local historians Roderick Martin and Gerry Martin. This post has utilised much of the research conducted by them and through a booklet (Birth and Life of 0P115-P) written by Lt Col Robert McMahon who was the commanding officer during the war period at the camp. Interestingly Lt. Col Robert McMahon, wrote the booklet in December 1944 (there is a date of 11th that month) and there is a footnote to the title which states ‘England 1943 – 45?’, the question mark obviously is used because he did not know when the camp would be closed or de-commissioned. Additionally, this post uses information recorded by others and given to the author (including pictures and verbal testimony) from the post war years through to its final closure in the 1970s, provides a rich history of the camp, and is used here with grateful thanks.
The camp was built by the British in 1942 for the U.S. Army as a Field Hospital which was operated by them between 1943 and 1945, then after the war the camp was used by various military units and finally was used to house Ugandan refugees in 1972/3 before being demolished in by 1976. Today, there are very few remains of the camp, which once had over 150 buildings. The author has extensively explored the open moorland of where the camp once stood to try and understand its layout and to try and find any remnants – there are very few ! As it is nearly 50 years since the camp closed it is probable that very few people who wander across the moorland know the history behind the camp, such was the extensive clearance that has taken place.
The original 115th Station Hospital was formed (in name only) in July 1923, being designated to the 7th Army Corp. It was then designated the 115th Station Hospital Unit in June 1929 but wasn’t made fully operational until September 1942 with and most of the men coming from New England and the mid-Atlantic states and the nurses were from mid-Atlantic and mid-West states. The unit arrived in the UK (Greenock, Firth of Clyde) on 26th July 1943 before taking the long train journey to Tavistock and onward to the camp by lorry.
The camp was opened as a 750 bed General Hospital virtually straight away, having briefly being occupied by another U.S Unit, who effectively ensured the camp was more welcoming than it might have been. It was used mainly by the US Army, US Navy and Coastguard along with some British Army Units who were stationed mainly in Plymouth. Amazingly, in just five months between August 1943 and the end of the year around 10,000 patients passed through the hospital, of which 4000 needed diagnostic hospitalisation and nursing. There were also 8000 outpatient sittings. The camp was always under staffed, which was compounded by the fact that as well as looking after the patients, the unit also had to run the camp, maintain and repair the buildings. Some of these tasks were undertaken by local people.
There was a build up of troops in 1943 and into 1944 as the invasion of mainland Europe approached. It was expected that many more casualties would be to brought to Plaster Down, therefore the initial 750 beds would be insufficient. Ward tents with additional walkways were erected bring the bed numbers up to 1180, then by D-Day (6th June 1944) the bed numbers were 1487. On 28th June 1944, the first D-Day casualties arrived (292 men). The surge of casualties didn’t occur until the Autumn of 1944, with 292 arriving on 6th October, 270 on 9th November, 319 on 27th November, 244 on 14th December, 270 on 21st December and a further 279 on Christmas Day. The total at the end of 1944 was 1364. 400 operations were carried out for the December admissions alone, which brought immense pressure on the staff. The snowy weather (nearly two feet of snow on Whitchurch Down) at Christmas 1944 compounded the difficulties at the camp
By Spring 1945, the numbers of patients reduced at the camp as field hospitals had been built in mainland Europe closer to the fighting. By April 1945, the hospital unit was given warning of being sent to Europe. By 28th April 1945, the remaining 28 patients had been sent to the 112th field hospital near Newton Abbot and on 23rd May 1945, the whole 115th Field Hospital Unit left for Metz (France), then Augsberg (Bavaria, Germany).
Post war, (1946) the buildings was used as a general hospital for local people and families of the US Army being downsized in stages from 750 beds to just 150 beds. The hospital was finally closed on 20th July 1947. Between 1947 to 1973, the camp had no real dedicated identity. It was used briefly by Polish refugees and German Prisoners of War. By 1951 the site was owned by the Ministry of Defence with various British military units being stationed there, albeit temporarily. During Summers in the 1950s, the camp was used by Territorial Army (TA) Units and in the 1960s it was used by the Woman’s Royal Air Corp. Permanent occupation by troops was considered in the late 1960s, with the camp being given a facelift before receiving soldiers returning from Aden. In June 1971, the 24th Infantry Brigade moved out and afterwards it was briefly used by the Army and the Royal Marines for training
In August 1972, the President of Uganda and brutal dictator Idi Amin gave Ugandan Asians 90 days to leave the country. Amin supported ethnic Ugandans and felt threatened by an educated Asian elite many of whom were bankers, civil servants, factory and land owners. From October 1972, Plasterdown was used as a refugee camp for some of the Ugandan Asians with initially 367 being housed followed shortly afterwards by another 150. The authorities wished to keep the refugee numbers to below 900. By 1973 the site was empty and attempts were made to find a new function for the 230 acre site which included as a temporary school and to temporary housing for the homeless. Following a mass sell off of equipment, the death knell came with, in 1976 the buildings being demolished and such was the effectiveness of the demolition, just about every sign of the hospital and camp was removed. Of note, is that Grimstone and Sortridge Leat ran through the site, but to avoid pollution it was diverted through a concrete pipe, which is the most obvious relic which can be seen today.

This map shows all the buildings of Plasterdown Camp from the 1940s to 1970s, which extended from the Horrabridge / Warren Cross road in the west to the Whimington / Warren Cross road in the east. The Grimstone and Sortridge ran through the camp, roughly north to south from where the map is annotated ‘sinks’, past the ‘Plymouth 12 MS’ then across the open piece of land. The leat is not shown on the map as it was channelled through a concrete pipe to prevent the water getting pollutedThis aerial photograph of Plasterdown Camp is from 1946, just one year after the 115th Hospital Field Unit left the siteThis fabulous article on Plasterdown Camp was written by local author Roderick Martin and is reproduced here with permission, with grateful thanksPlasterdown Camp from the south west (Jordan Lane) where the road crosses Grimstone and Sortridge Leat – date unknownThis is the same view of the previous black and white photograph taken in October 2025.

This picture is the front cover of the booklet written by Lt Col Robert McMahon who was the commanding officer during the war period at the camp. Most of the war photographs in this post were taken from this booklet, which is the personal copy loaned to the author by Jill Fitzsimmons. Interestingly Lt. Col Robert McMahon, wrote the booklet in December 1944 (there is a date of 11th that month). Note the footnote to the title which states ‘England 1943 – 45?’, the question mark obviously is used because he did not know when the camp would be closed or de-commissioned. Inside McMahon started by titling the text with ‘The Birth & Life of the 0115-P’ or TWO YEARS OF SNAFU* AT HOME and ABROAD. *SNAFU is an acronym that is widely used to stand for the sarcastic expression “Situation normal: all (fouled) up” and is an example of military slang. The term has been censored here
For the purpose of this post, using cartographic and photographic evidence, the author has subdivided the camp into 15 sections and provided a best guess interpretation (in the absence of a camp plan). The author has recorded the grid reference for centre of each building / feature. These grid references are recorded later in this postThis picture is a 21st century aerial photograph superimposed onto a 20th century mapSection 1 – the buildings by the main gate next to the Horrabridge / Warren Cross road. The road through these buildings (south west to north east) leads through to the 12 Miles to Plymo milestone and the Grimstone and Sortridge LeatMain gate, likely taken in 1960s or 1970sThere is still evidence of the road leading through the former main gate – taken in October 2025Front gate black and white image superimposed onto a picture from October 2025. The pictures were lined up through knowledge of where the guard house was and by the tors in the backgroundWhere the walking pole is positioned is where the guard house was located. It is Section 1, Building 1 as per the authors annotation and is at SX51566 72282. There is evidence 50 years on, of some minor ground disturbance, which ordinarily would go un-noticed to the casual observer
This is a 1946 aerial view of the main entrance with buildings. The building at the bottom left is the guard house
A view of the main entrance from the road, now used as a car parkSections 2-5; the buildings which are located next to the Horrabridge / Warren Cross road were most likely accommodation for staffThis picture is courtesy of John Stickland, with thanks. John explains that this is a surviving building from the camp, which is on private land, namely the grounds of the former Woodhouse Garden Machinery at Bleak House. Mark Woodhouse, the former proprietor of the business, told John that his father bought it at the clearance auction in 1976ish and they moved it back to Bleak House in sections and re-erected it. It is likely to be one of the accommodation units from the Hospital, possibly from sections 2-5 as per the authors map annotationsA front on view of the former accommodation block
Sections 2-5 – the buildings which are located next to the Horrabridge / Warren Cross road from an 1946 aerial photograph
This is a general view of sections 2-5 accommodation blocks as seen in October 2025. There is some ground disturbance which can be detected even in 2025. The picture is a view from SX51663 72052 next to Section 4, Building 4This faint track leads north(ish) from Section 4 through Section 3 and 5. This must have been the pathway used by staff to and from work on a daily basisThis is section 4, building 4 recorded at SX51659 72058. The raised gorse being where the building once stoodMoving north up the central track between the groups of buildings to Section 3, Building 7 at SX51649 72117Section 6. The author surmises that they were more accommodation blocks (possibly the officers) and other buildings sandwiched between the Grimstone and Sortridge Leat (by the milestone) and start of Administration Circle. 1946 aerial photograph of the section the author has annotated as section 6Using the National Library of Scotland Maps, the author has recorded the National Grid Reference (NGR) for the centre of every building / feature shown on the previously annotated maps for sections 1 through 6This concreted section with bricks and debris is where there must have been a bridge which crossed the ‘dry leat’ (as it was sent down a concrete pipe through here)This milestone is inscribed ’12/MILES/TO/PLYMo’ and is unusually around 150m from the road, so most likely would have been moved. It is believed to have been (originally) erected in 1832. Note the concrete pipe on the north east bank of the leat, which where the water would have once flowed The milestone and some locals. The milestone is 118cm tallSection of the concrete pipeDebris in the Grimstone and Sortridge LeatPonies by a section of the exposed concrete pipeYoung FoalThis annotated map shows the approx. location where the next picture was takenThe author believes this photograph may have been taken in the 1940s or 1950s. Its location appears to be just north west of the leat and milestone (by virtue of the orientation of the buildings, it proximity to the administration circle (flagpole) and the back drop of Pew Tor) as per the annotated map previously shownLocation in November 2025 of the previous black and white photograph, just north west of the leat and milestoneSuperimposed black and white picture on the November 2025 photograph with Pew Tor appropriately line up in the centreThis ramp feature with a piece of concrete at SX51651 72466Another view of the leat which separated the camp – it is likely is was just a dry ditch when the camp was operationalA dual concrete pipeline was put in place for the Grimstone and Sortridge Leat to flow through presumably to prevent pollution. Note that the course of the pipeline crosses the course of the leat we see todayThe pipeline where the Grimstone and Sortridge Leat makes a 90 deg bendThe pipeline ‘inlet’ (marked as ‘sinks’ on old map) is located at SX51614 72514The ‘dual pipe’Section of walling near the concrete pipe at SX51625 72482Broken pipe near the Milestone on east side of leatMisc piece of debris from the camp, which is located away from any of the original structures or featuresThis small piece of concrete is from section 8, building 1 at SX51738 72437. This would have been at the south west end of the administration circleThis small piece of concrete was found amongst the gorse in what would have been the centre of the administration circle at SX51745 72475The outline of the administration circle is still shown on some recent (21st century) aerial photographsThis ring and connecting bar was not on site but shown to the author by someone who lives local to the former camp. This artefact was believed to have been a restraint of some kind. The author has been unable to confirm this.Section 7 building annotation which was the north west side of the administration circle. Of interest is the old tennis court and chapel identified on the old map. The Grimstone and Sortridge Leat here was not piped This annotated map shows the approx. location where the next picture was takenThe administration circle where the flagpole was located. One assumes this is where the main headquarters was located. Note the speed limit was 15 mphThe administration circle in November 2025This composition superimposes the old black and white photograph onto the November 2025 picture. Created by lining up the background tors and knowing where the flagpole was located (amongst the gorse) Administration circle from an aerial photograph from 1946. The tennis court lines very evident from the photographThese pictures are from the Lt. Col Robert McMahon and were of staff either from between July 1943 and April 1945HeadquartersAmongst the gorse is this piece of concrete with a hole next to it, which is at SX51753 72478. The location suggests to the author this was the flagpolebase

More pictures from the Lt. Col Robert McMahon booklet of the wards and an operating theatre. They were taken from between July 1943 and April 1945. In all likelihood, as the wards do not appear full, it is likely that the pictures were taken pre D-Day (6th June 1944)More pictures from the Lt.

There were 50 officers, 135 volunteers and 220 National Servicemen.General Sir George W. E. J. Erskine of Southern Command paid a flying visit by helicopter to the camp in 1956. The article from which this photograph was taken suggests there was a ‘sheep pat’ on to which the General had to step on on alighting from the helicopter which was ‘thanks, to the last minute arrangements of the native population of Plasterdown’A Scottish Territorial Unit from late 1950s marching to Plasterdown Camp – picture courtesy of Jill FitzsimmonsFrom a report in ‘The Abingdonian’ (a school publication by Abingdon School) the details of their Combined Cadet Force (C.C.F) camp in 1963 can be summarised as follows: On the first day they went shooting; on the second day, they embarked on a 72-hour Arduous Training exercise (initially in sunshine so hot that two Cadets suffered from heat exhaustion, and one of them had to drop out of the exercise). The exercise had to be abandoned due to mist on the following day, when one patrol got lost! The camp didn’t appear to get any better as they had planned to hold the open air drumhead service which was cancelled due to the mist then on the final day an exercise in fighting patrols was curtailed due to a army regular officer failing to show up. The person who wrote the article about the camp signed off on a positive by saying “All in all, though, a smooth-running, pleasant camp, which served very well as a “digestif” at the end of a crowded term”.

In October 1972, initially 450 then another 150 Ugandan Asians were housed as part of resettling them, as they escaped persecution in their own country. They were given only 90 days by the dictator Idi Amin to leave their own country.
