In the early years at Warboys, the Pathfinders had had a difficult start. High loses and poor results were compounded by poor weather. But in early 1943 the Lancaster began to arrive, and the old Wellingtons began to be phased out. The weather however, takes no account of this and for the early part of January 1943, it continued to envelop the country preventing flights from Warboys going much further afield than Wyton, a stones throw away from their base. Even so, on the 13th, the Pathfinders took another major step forward, being formed into a new and unique Group of their own, No. 8 (PFF) Group, with Don Bennett (now an Air Commodore) remaining at the helm.
On the 26th, the squadron were able to use the new Lancasters for the first time on operations, a bombing raid to Lorient in which 4 Lancasters from Warboys took part; ‘ED474’, ‘ED485’, ‘W4851’ and ‘W4853’. On the 27th the same four aircraft, with different crews, went to Dussledorf, an operation that saw the use of Oboe Mosquitoes for the first time, and a mission that was followed on the 30th by Hamburg. All aircraft returned safely from each of these early operations – 1943 was beginning to look better already.
This run of ‘good luck’ ran well into April, with a relatively low loss rate per operation. This included on April 16th, the death of Sgt. Patrick Brougham-Faddy (S/N: 577758) and the crew of both Lancasters ‘W4854’ and ‘W4930’. What perhaps makes this incident more notable, was the fact that Sgt. Brougham-Faddy was only 18 years of age, making him amongst the youngest to lose their life in Bomber Command operations. With him lost on that mission was also: his pilot P/O. Harald Andersen DFC; P/O. Kenneth Bordycott DFC, DFM and P/O. Frederick Smith DFM along with ten other experienced aircrew. These losses were a major blow to both the Warboy’s crews and the Pathfinders.
In June 1943, the Navigation Training Unit, a Lancaster based unit formed at RAF Gransden Lodge began its move, taking residency at both Upwood and here at Warboys. The split was not be in everyone’s favour, running a unit on two different sites initially caused some difficulty as the idea of the unit was to train crews in navigation techniques ready for postings to Pathfinder squadrons.
By the time 1943 drew to a close, fifty-seven aircraft had been lost from Warboys, a mix of both Lancaster MK.Is and MK.IIIs, the Wellington now having been replaced entirely within the squadron.
The cold winter months of 1943 – 44 signified another major event in Bomber Command’s history – the air campaign against Berlin.
For almost 5 months, November to March, Bomber Command would attack Berlin relentlessly in pursuit of Harris’s doctrine of area bombing. The Short Stirling would be withdrawn as the losses mounting were unsustainable, a similar fate that began to land on the door of the Halifax. Some compared the Lancaster to the Halifax, similar to comparing a “sports car and family saloon”*4. The handling of the Lancaster being far superior to that of the Halifax. As a result, the Lancaster squadrons would bear the brunt of the campaign, and Warboys crews would be in the thick of it. The Pathfinders using an updated version of H2S, would operate outside the range of Oboe, the land based navigation system introduced operationally a year before.
The cold of January 1944, did nothing to dampen the flights nor reduce the combat fatalities. Raids on Berlin, Brunswick, Munich and Frankfurt saw heavy losses (seventeen alone failed to return to Warboys in January, all experienced crews) and numerous aircraft returning early. For 156 Sqn this was disastrous, the squadron began to get a name for itself being referred to as the ‘chop’ squadron and consequently morale fell. With high losses the survival rate fell to an estimated 15%, *3 an unsustainable level of loss for any squadron. For the last fourteen days of January the squadron was effectively reduced to non-operational flights, and in a desperate attempt to bolster the men’s spirits and raise morale, a royal visit was arranged for the King and Queen. Both their majesty’s arrived on February 9th, where they talked to aircrew and took lunch in the Officer’s Mess. After a short stay they departed Warboys going on to visit other Pathfinder airfields in the area.
By the end of February 1944, 156 Sqn were prepared to leave Warboys, maybe a new start would give a new impetus. This move would be a direct swap with the remaining Lancasters of the Pathfinder’s Navigation Training Unit (NTU) based there. Perhaps ending the operating of the unit on two sites had been seen as an ideal opportunity to ‘kill two birds with one stone’, moving 156 and reuniting the NTU. Whatever the reason the transfer began with a small advanced party taking the short drive to RAF Upwood.
By mid March the move was complete, and Warboys settled into its new role with a full complement of the NTU, hopefully now, the harrowing tales of loss were a thing of the past. With courses of generally three to five crews every few days, turnover was rapid.
With the Mosquito taking a greater role in the Pathfinders, more crews were needing training in its operation. The 1655 (MTU) Mosquito Training Unit (formerly the 1655 Mosquito Conversion unit) originally formed at Horsham St. Faith in 1942, moved across from RAF Marham in Norfolk; Warboys was now awash with twin and four engined aircraft.
The Training unit would only stay at Warboys until December, at which point it moved to Upper Heyford where it would disband at the end of the year, being renumbered 16 Operational Training Unit (OTU). However, for that short time at Warboys, it grew extensively, gaining five flights including a mix of aircraft for training purposes. Whilst pilots were taught how to fly the Mosquito, the navigators were taught Pathfinder navigation & marking techniques, all prior to joining as a new crew for final training and ultimately postings to a Pathfinder squadron.
Many of the aircraft delivered to Warboys were veteran aircraft themselves, having served with other numerous squadrons. Mosquito DZ606 which initially arrived in April 1944, had already flown at least nineteen operational sorties before arriving here. It was then passed on to another unit (139 Sqn) before returning with a further twenty-nine sorties under its belt. The dedication of ground crews, ease of repair and the reliability of the Mosquito enabled it to complete thirty-seven more operations with other units before the year was out. It was eventually struck off charge in 1945 after being badly damaged.
One other notable example that appeared at Warboys with 1655 MTU, was W4053 which had been the Mosquito Turret Fighter Prototype in 1941. The (bizarre) idea of this was the fitting of a four gunned Bristol turret behind the cockpit, rather like a Boulton Paul Defiant. On tests though, the turret seized when turned to the front effectively trapping the occupant inside. After running further tests with the same results, the project was abandoned and no one was allowed to fly in it again – even though some did try! The aircraft had its turret removed and served with both 151 and 264 Squadrons before passing to 1655 MTU here at Warboys. In November 1944 it was damaged in a landing accident, repaired and then reused by the unit when it was renumbered as 16 OTU at Upper Heyford, where the Mosquito was destroyed in a crash.
With the Mosquito training unit moving away, the Navigation unit remained the sole user of Warboys, but years of use by heavy bombers had had a toll on the runway, their surfaces beginning to break up and cause problems. Warboys was going to need considerable repair work carried out. However, the Navigation unit remained here until the war’s end. On the 18th June 1945 a communique came through from Bomber Command and 8 (PFF) Group, announcing the disbandment of the Navigation Training Unit., Staff began postings elsewhere, the last courses were completed and ‘Cooks’ tours (tours taking ground crews over Germany to see the devastation) were wound down.
Before the closure of Warboys though, two more squadrons would arrive, 128 Sqn and 571 Sqn, both Mosquito Pathfinder squadrons. 571 was disbanded here on September 20th, whilst 128 Sqn transferred out to B58/Melsbroek, then Wahn where it was disbanded in 1946.
After the training units were disbanded all flying ceased. The RAF did return briefly with Bloodhound missiles in 1960 staying for 4 years until the airfield was finally closed and sold off.
With that, Warboys was gone, and its remarkable history now a distant memory. But these memories were not to be forgotten forever. The local village commemorated the loss of one particular pilot who on the 10th April 1944, lost his life whilst flying a Lancaster over the Welsh countryside.
Flt. Lt. John L. Sloper DFC and Bar, was a veteran of 156 Sqn who had transferred out of operational duties to the Training Unit after completing his tour of duty on December 29th 1943. His last mission being a bombing raid to Berlin in Lancaster JB476. Flt. Lt. Sloper had achieved his quota in just seven months. He joined the Mosquito unit to pass on his skills to others, his personality, knowledge and determination making him very popular with the other crews.
Flt Lt. Sloper (S/N: 147214) was killed in Lancaster ‘JB 471’ during a cross country navigation flight near the village of LLanwrtyd Wells in Breconshire. The aircraft crashed after entering cloud, the ensuing fireball killing all those inside. Flt. Lt. Sloper’s remains were buried at Haycombe Cemetery and Crematorium, Bath.
The site today houses small industrial units, but it is primarily farmland. Only a small section of the main runway exist, and this has farm buildings upon it. This section, has been cut by the original A141 now a ‘B’ road, and evidence of the runway can still be seen either side of the road.
The farm entrance has a large sign with a Lancaster modelled out of metal. Two memorials on the gate posts mark the runway (since my original visit the sign and one of the memorial plaques appears to have been removed, though I have yet to verify this). Across the road from here, you can see the extension to the runway and the remains of a small building, but probably not war-time due to its location.
There is luckily a footpath that circumnavigates the field called ‘The Pathfinder Long distance Walk’, and uses that iconic aircraft, the Mosquito, as its icon. This path allows views across the airfield and access to some of the remaining buildings.
Entry to the path is toward the village, a gated path that is actually part of the perimeter track. As you work your way round, to your right can be found one of the few Air Ministry designed pill boxes. The manufacturer of these mushroom defences being F. C. Construction, they were designed in such a way as to allow machine gun fire through a 360 degree turn. Often referred to as ‘Oakington’ pill boxes, there are only a few remaining today.
Also, deeply shrouded in hedges and undergrowth, another structure possibly a second pill box or the battle headquarters. With permission from the farmer, you may be able to access these, but they look in a rather dangerous condition.
Further along to your right is where one of the T2 hangars would have stood before its demolition. Tracks lead away from here, and there is what appears to be further examples of airfield architecture buried amongst the trees.
The perimeter track takes you around the rear of the airfield across the threshold of the main runway and round the perimeter track. A local model flying club now uses this part of the site between the runway and perimeter track. To your right would have been the bomb store, now open fields laden with crops rather than bombs. There are a few buildings here marking the boundary of the store, now used for chickens and extensively ‘modified’ by the farmer. They house farm machinery, a far cry from what would have been here many years ago.
The track then takes you away from the site and out across the Cambridgeshire countryside.
Returning back to the road, we go in the opposite direction from the village and come to the entrance of the industrial site. These buildings stand on the perimeter track marking the western corner of the airfield.
Next to this part of the site, is a large telecommunications transmitter, apparently the origins of the site being 1941. Whilst its use and history is somewhat difficult to locate or verify, it is known that this was a Ground Control Interceptor (GCI) Radar Station used to lock fighters onto incoming enemy aircraft. Later, there was a high-powered transmitter here used by RAF Mildenhall and RAF Wyton. It was also used to communicate with the V bombers on long-range flights. The mast believed to be original, has been updated and refurbished for telecommunications purposes, but the block house remains behind high fencing with very strong padlocks!
The majority of the admin sites are located along the A141 toward Wyton, some evidence exists here but the majority have long gone. Return toward the village and find the church; located just on the outskirts of the village.
A superb memorial window and roll of honour can be found here, and it is well worth the effort. In Huntingdon town is the former Headquarters building of the Pathfinders, Castle Hill House, which now belongs to the local council. A blue plaque describes the historical significance of the building.
Designed initially as a satellite airfield, Warboys went on to be a pioneering airfield for a new and dedicated team of bombing experts. With 156 Squadron it took the war deep into the heart of Nazi Germany. As a result it suffered great losses, but without doubt it performed one of the most vital roles in the latter parts of the war and it’s a role that should not be forgotten beneath waving crops and developing industry. The name of Warboys should be remembered as a Pathfinder icon.
After we leave Warboys, we head to her sister station to the west, and an airfield with a history going back to World War I. This airfield saw a spy caught and hanged; the making of a film using Lancasters, and more recently the site of a hospital for the treatment of victims of a nuclear war. We of course go to RAF Upwood.
