RAF Hunsdon – The Mosquito Bites (Part 4)

In Part 3, we saw how Hunsdon and gone through various squadrons, operating the ill fated Turbinlite system which was soon withdrawn, and onto the arrival of the Mosquito, a deadly aircraft that could out run every German aircraft at its introduction. It was now time to bite, and the bite would come directly at the heart of the Gestapo.

In one of the war’s most famous attacks, so many questions would be asked, but answers would be short-coming and the truth may never come out. 

The new wing, previously formed at Sculthorpe, would consist of the three multinational squadrons, a ‘British’, Australian and New Zealand unit, and all would be based at Hunsdon as part of the RAF’s Second Tactical Air Force (2TAF) designed to support troops in the forthcoming invasion.

Between 1944 and 1945, 140 Wing would carry out many daring low-level bombing raids against V weapons targets, along with a key Gestapo building and a prison in occupied Europe. These particular raids were designed to both free captive resistance fighters and destroy important Gestapo documents. Operation Carthage took place in Denmark and occurred whilst the wing was based at RAF Fersfield in 1945, but the first, Ramrod 564 or ‘Operation Jericho’ as it has since become known, took place whilst they were based here at Hunsdon in early 1944.

There is a lot of speculation around Ramrod 564, many of the official records are missing, inaccurate or even vague. The operational record books for the four squadrons involved (three Mosquito and a Typhoon) are recorded as ‘secret’ and contain no details other than aircraft, times and dates.

However, we do know that the Operation, formulated by Air Vice Marshal Basil Embry, would be critical, even the amount of explosive itself had fine limits. Time was also of the essence, as several prisoners were thought to be destined for execution and so a time limit was placed on when it needed to be done by. The exact time of day was also critical, they needed as many guards to be in one place as possible, and the prisoners needed to be safely gathered together out of harms way. So, a time of 12:00 pm precisely on a date between 10th and 19th February was chosen, as both the guards and prisoners would be having lunch at this time. In the attack, six Mosquitoes would breach the outer wall in two places, whilst a further six would bomb the main prison buildings allowing the prisoners to escape whilst killing as many guards as possible.

Embry elected himself to lead the attack, but this was blocked by those higher up, As a result, and much against his wishes, Embry therefore had to choose a successor. Group Captain Percy C. Pickard (D.S.O. and two bars, D.F.C.) was chosen, but even though he was known as an expert pilot and leader, Embry was not convinced of Pickard’s ability to complete the job at such low level. Despite his reservations though, Embry duly informed Pickard of the decision and preparations for the operation began in earnest.

On February 18th that year, a day after the initial planned attack and in extremely poor weather, 19 Mosquitoes including a photo reconnaissance MK.VI (from the Operational Film Production Unit (OFPU) for propaganda purposes),  took off to attack, breech and destroy the walls and main building of the Amiens prison. A famously brave act, it resulted in the death of 3 crew members; Gp. Capt. Percy C. Pickard, and Flt. Lt. John A. Broadley, (RNZAF), both in Mosquito HX922, ‘EG-F’ and Flt. Lt. Richard W. Samson, (RNZAF) in Mosquito MM404 ‘SB-T’. Samson’s pilot, Sqn. Ldr. A. I. McRitchie survived his crash and was taken as a prisoner of war. Two Typhoons from 198 Sqn escorting the Mosquitoes are also thought to have failed to return (the ORBs don’t confirm this). Considered a success at the time, evidence has since come to light to suggest that the operation was ‘unnecessary’, and may have failed to achieve anything more than a successful PR role (see end note). ^*1

(A better quality version is available on the Pathe News website.)

All that aside, the raid took place at very low level and in poor weather, with bombs dropped against the wall with delayed fuses. There was little resistance on the flight in and Typhoons provided higher cover when it was needed.

The route would take the Mosquitoes from Hunsdon to Littlehampton – then via appropriate lattice to Tocqueville – Senarpont – Bourdon – then one mile South Doullens – Bouzincourt – two miles west-south-west to Albert – Target – Turn right – St. Saveur – Senarpont – Tocqueville – Hastings and back to Hunsdon.

During the flight out, four Mosquitoes and three Typhoons of 198 Sqn became lost in swirling snow and were forced to turn back as they had now lost contact with their main formations. The remaining crews flew on, but whilst over France a fifth Mosquito, flown by Flt. B. Hanafin, suffered engine problems and was also forced to turn back. On his return journey his was attacked by Flak from which he was seriously injured. Helped by his navigator the two were able to land back at RAF Ford where he was given medical treatment for his injuries.

Just three minutes behind schedule, the first wave of three aircraft followed the main road toward the prison’s eastern wall at tree top height. The second wave would attack the northern wall. Wg. Cdr. I. Smith 487 Sqn went in first dropping the bombs with 11 second fuses against the wall.

The third and fourth waves attacked the south-eastern main building and north-western end respectively. Chaos then ensued inside the prison, as over running bombs had caused some damage inside and some prisoners were injured or struggled to escape.

Noting now that the walls and prison had been breached, the signal to abort was issued over the VHF radio probably by both Pickard and the OFPU Mosquito flown by Flt. Wickham (both the code word “Red, Red, Red” and who sent it are also disputed) instructing the four aircraft of the 21 Sqn Flight not to bomb. The message was heard by the flight, when they were between 2 and 4 miles out from the target, and so returned to base without dropping their payload.

During all this time, FW.190s continued to swarm and various dogfights took place between them and the Typhoons, but not before they had attacked some of the fleeing Mosquitoes who also returned fire.

It is unclear at what point in the attack that Pickard was shot down, but a Focke Wulf 190 flown by the ace Feldwebel Wilhelm Mayer, severed his tail sending his aircraft to the ground near to Saint Gratien. The resultant crash killing both occupants.

The story goes that Pickard had left his dog ‘Ming’ at RAF Sculthorpe, their previous airfield,  to be looked after whilst he was away. On the day he was shot down, 18th February 1944, the dog fell gravely ill. Pickard’s wife, Dorothy, went to get him and sensed, that after seeing the state of the animal, that Pickard had been killed . It took months for Ming to recover, and some years later whilst living in Rhodesia, Ming went outside, looked up to the sky as he always did when Pickard was flying, heard a whistle, collapsed and died.*⁶

Of the 700 prisoners detained inside the prison that day, 258 of them escaped,102 were killed and 74 were wounded*⁷, but the success remained secret from the public for a further eight months. With so much speculation surrounding the attack, it will no doubt remain one of the mysteries of war, but it was without doubt, an incredibly brave and daring mission that cost the lives of three superb young airmen.

A podcast using eyewitness accounts from the Imperial war museum can be heard through their website.

The Amiens raid was not the only daring low level raid carried out by the wing whilst at Hunsdon however. Airfields along with the Hazmeyer electrical equipment factory at Hengels in Belgium, were also attacked at low level. On this particular operation Mosquito MM482 was hit by intense flak setting the starboard engine on fire. As a result, the aircraft flown by Canadian Sqn. Ldr. A. W. Sugden with navigator Fl. Off. A. Bridger, was lost and both men were listed as missing. Having been with the squadron since 1942 they were considered ‘old timers’ by the others and were sorely missed.

The three squadrons of 140 Wing would soon depart Hunsdon though, leaving the joy of success and the turmoil of a thousand questions behind them. 464 went first on March 25th whilst 21 and 487 Sqns would both leave mid April, both moving to RAF Gravesend in Kent.

However, a month before the wing moved away, another Mosquito squadron would move in temporarily, meaning the airfield was awash with the aircraft of varying types. 409 (RCAF) Sqn’s time would be short, remaining here for just over a month before departing mid May, but they would return in June that same year staying for a further two months. Their final departure on the 25th August 1944, would end their association with Hunsdon for good, a move that took them to the continent and forward bases across the low countries.

Between June and the end of 1944, no less than six squadrons would come and go, most of them moving to the continent as the allied advanced progressed toward Germany. Each of these units would bring further Mosquitoes with them, with marks ranging from the MK.II and VI (418 Sqn); to the XIII with 29, 264 and 48 Squadrons, on to the XXX with 219 and 151 squadrons.

The longest to stay of these six units would be the first, 29 Squadron. Formed in 1915, they have operated almost continuously ever since, with just a short break between the wars and some reformation post war. Today they are based at Coningsby in Lincolnshire and are the southern most QRA Squadron currently flying Typhoons. They were in 1987, the first operational squadron to be equipped with the Tornado F3.

An air raid shelter now exposed.

At Hunsdon in 1944 though, the move would come as a surprise and with some reservations, but once here, it was considered to be an ‘improvement’ on West Malling. 29 Squadron would fly the NF. XIII Mosquito, arriving here on June 19th that year. The NF.XIII was the first variant night fighter to have the strengthened wing of the FB.VI, with increased fuel load and Merlin 23 engines. One such example, HK428 ‘RO-K’built at Leavesden, joined 29 Sqn at RAF Ford in early 1944.

On October 24th that year, during a flight test at Hunsdon, the aircraft suffered an overheating starboard engine and inactive flaps whilst in poor visibility. As a result the aircraft overshot the runway and crashed into a hedge causing the starboard undercarriage to collapse further damaging the aircraft. HK428 was subsequently repaired and passed to the Gunnery School at Catfoss in early 1945. It was eventually one of many that met the scrap man’s axe in 1946.*⁴

The Squadron would carry out patrols and intruder operations and whilst many of these were ‘uneventful’, several enemy aircraft were shot down including both Ju. 88s and Me. 110s. The last months of the war though were not all plane sailing. On July 1st, an accident during a flying test resulted in the loss of two good airmen and friends, Flt. Lt. John Barry and Fly. Off. Guy Hopkins.  A second Mosquito was hit by light flak at 500 feet on the 5th. Flying home on one engine, the aircraft made and emergency landing at RAF Ford, but somersaulted on the ground writing the aircraft off. Thankfully, and remarkably, in this instance neither crewman sustained any injury.

As the allies advanced more intruder missions took place. On some days the squadron was “let loose” to pick and locate their own targets, many choosing road or rail stock, damaging many trains as a result. The rest of the year and into 1945 would be the same. Intruder missions, ‘Flower‘ Operations (attacks against German night fighters at their airfield) brought some results. Then almost as quickly as they arrived they were given notice to move once more, and a huge party on the night of February 22nd 1945 preceded their departure to Colerne

Two other units arrived at Hunsdon after 29 Sqn, those of 418 (25th August, 1944) and 219 (29th August 1944) Squadrons. With all these Mosquitoes there must have been little room for any more aircraft as Hunsdon quickly filled  up with the type. 219 Sqn would quickly move out though, leaving what little space there was for a new unit, 488 Squadron who moved in the day prior to 219’s  departure. The last of this group of units to arrive that year was 151 Squadron. All but 151 transferred to the various airfields on the continent whilst 151 remained in the UK, leaving Hunsdon on March 1st 1945. It had certainly been a busy period at this Hertfordshire airfield.

1945 would be a reflection of the hectic movements of 1944. However, it would also bring a greater variety of aircraft as detachments arrived posted away from their main unit. It would also bring a slight change of role, as the range of twin engined Mosquitoes departed, single engined fighters came in.

The first would be a small detachment of 285 Sqn Hurricanes who resided here between January and June, followed in the beginning of March by 154 Sqn with Mustangs and Spitfires. 154 Sqn time here would be very short though, sadly ending their days here, just eighteen days later.

Almost at the same time, these units would be joined by 501 Sqn and 611 Sqn, 501 also ending their days of active duty here with their Tempest Vs, whilst 611 would swap their Spitfire VII for Mustang IVs before moving off to Peterhead and disbandment also. Both these units would however rise again the following year being reborn as the jet age dawned, to live on for a few more years.

442 Sqn, another Canadian unit, ended the flurry of units arriving in March that year when they brought Spitfire IXEs back for a spell from the continent, being stationed recently at B80 (Volkel) and B88 (Heesch), they had seen action first hand before arriving here. They soon replaced these aircraft with Mustangs though, moving on to RAF Digby in May as the war ended. 442 were also a short lived squadron, only being formed at Digby in February 1944. Their operational life had lasted just eighteen months.

April and May saw the last of the front line squadrons to reside at Hunsdon. The closing days of April saw 441 with Spitfires and 287 Sqn with a detachment of Tempests Vs. Both these units would move on elsewhere before they too saw the curtain fall, and their days as operational units cease. Like its sister squadron, 441 had only been operational for eighteen months, being formed in unison. In fact, their entire operational record matched to the day, even when they moved abroad.

Hunsdon then closed to operational activity, being used to receive returning men and materials up until mid 1946 whereupon it was placed into Care and Maintenance and allowed to run down. The tower was demolished very soon after the war ended, and the site was returned to agriculture. In total, Hunsdon’s crews accounted for over 220 enemy aircraft destroyed or damaged – a remarkable feat in any airfield’s chapter.

One of the original dispersal pans.

Today Hunsdon remains one of the more accessible airfields of Britain. A number of public footpaths criss-cross its boundaries allowing unprecedented access to it. It is still an active site, allbeit much reduced – a small microlight operation exists here and has done since 1997. Using three small grass runways it has brought life, in albeit a small part, back to this old wartime airfield.

The perimeter track and narrow sections of all its runways still exist today and can be walked using a variety of footpaths. Along these paths and off to the sides can still be seen examples of runway lighting, drainage, inspection covers and even a small number of buildings.

The parachute store is one of the most notable of these, used by the farmer for storage, it is located at the north-western side of the airfield near to the former admins site and where the tower would have stood before being torn down. Also near here is the fire tender shed, now home to the local shooting club, a number of latrines \ wash blocks can also be found hidden amongst the trees to the south-east. The battle headquarters rests nestled amongst the crops still watching over the site, and small defence trenches and shelters can be found to the north and again these are visible from public footpaths. A number of airfield defences buildings in the form of pill boxes and an Oakington style pillbox can also be found around the site.

Many of these examples are buried amongst the undergrowth and are most easily seen in winter when the thorns and vegetation are at their lowest. Careful searching will also reveal a number of minor archaeological examples but again best in the winter when crops and weeds are minimal.

To the northern side of the airfield, next to where the microlight site is based, is a memorial to the crews of all nationalities who were based here all those years ago. Formed from a propeller boss of a Mosquito, it was donated to by the former Mosquito Museum (now de Havilland Aircraft Museum), it stands proud looking down what was the length of the secondary runway. A further memorial plaque can also be found on the wall of the village hall.

Hunsdon is a small site with a big history. It played a large part in trials of new innovations, carried out night intruder missions, and attacked with daring at low-level, at the very heart of the Gestapo. Hunsdon and its crews proudly earned their place in the annals of world history.

After walking Hunsdon we travel the short distance to the north-east to the outskirts of Bishop Stortford and a little known about airfield that is all but gone. We go to RAF Sawbridgeworth.

Further Reading and Sources (RAF Hunsdon)

^*1 – The Amiens raid is one that has become embedded in history and is beyond doubt an incredible and daring low-level raid that succeeded in its aim. However, official records seem to have many errors, anomalies or missing details that it is very difficult to ascertain the accuracy of these historical ‘facts’.

The ORBs for each of the four squadrons give no details other than an ‘operation to France’, some crew names and aircraft numbers. There is no record of the use of the word ‘Jericho‘ but there are two sides to this story.

Some authors including Rowland White “Mosquito” and John Laffin “Raiders – Great Exploits of the Second World War“, both cite Basil Embry as the creator of the name ‘Jericho‘ before the missions took place, whilst Robert Lyman “The Jail Busters” cites a French film, made in 1946, as the author of creator of the name. Some believe the name was created by various media outlets since then whilst others say that Embry created the name after the operation had been carried out. It is however, widely considered that it was a post-war name as the original operation was ‘Ramrod 564‘ and none of the ORBs use the name ‘Jericho‘.  To further add mystery, the use of the title ‘Renovate‘ has also cited, but records in the National Archives show this as the secret VHF code word to be used by aircraft on the operation and not the Operation title.

The name aside, and more recently, one of the French Resistance fighters revealed his doubts about the operation, and considers that it may have been nothing more than a propaganda operation or a diversionary attack linked to D-Day. One book (one amongst many) on the subject has been written by author Simon Parry and historian Dr Jean-Pierre Ducellier entitled ‘The Amiens Raid – Secrets Revealed‘ and is published by Red Kite. It goes into the details of the raid and possible reasons behind it.

There have also been theories that it was an MI6 operation but due to the nature and secrecy of the mission, little evidence is publicly available to substantiate this.

Of those who lost their lives, both Pickard and Broadley are buried in St. Pierre Cemetery, Amiens, whilst Sampson is buried in the Poix-de-Picardie cemetery in the Somme region.

RAF Hunsdon – The Arrival of the Mosquito (Part 3)

In Part 2, we saw how the Turbinlite system failed to produce what was expected of it, and eventually the system was scrapped and the squadrons disbanded. Those left at Hunsdon continued the night operations but soon they too would depart this Hertfordshire airfield leaving room for an influx of Mosquitoes – de Havilland’s ‘Wooden Wonder’.

On May 5th 1943, 85 Sqn would officially receive its squadron badge, although it was a former World War One Squadron, it had never been officially presented with it, and time had caught up. With the whole squadron lined up outside the Bellman Hangar, A.O.C. 11 Group, Air Vice Marshall H.W. Saunders, C.B.E., M.C., D.F.C., M.M., gave a speech highlighting how well the squadron had performed; shooting down ninety enemy aircraft in France, fifty in the Battle of Britain and a further twenty in night operations whilst at Hunsdon. He went on to highlight the number of decorations its crews had been awarded: four D.S.Os; seventeen D.F.Cs; three D.F.Ms, and Bars to both the D.F.Cs. and D.F.Ms. He then presented the station badge to the Commanding Officer Wing Commander Cunningham. At this point it was announced that the squadron would be moving south to West Malling in Kent and he wished the squadron good luck.

With just a few more days left before departure,  operations continued and on the 8th, three more JU. 88s were spotted but intercepted by Spitfires from other squadrons before the Mosquitoes could get to them. It was not to be the glorious ending 85 Sqn had hoped for.

After a farewell dinner for both 85 and 3 squadrons in the officer’s mess, preparations began for the move. Three Harrows arrived to collect  personal belongings and equipment, and then, on the 13th, 85 Squadron departed, all ten aircrews performing individual flypasts over the watch office to show their respect and thanks to those who had worked along side them, it was a sad day for Hunsdon.  The Harrows once loaded, departed shortly after with the main ground party departing by train soon after that.

The dispersals and accommodation did not remain vacant for long though, they were immediately taken over by a new squadron, 157 Squadron along with their servicing wing 3081 Servicing Echelon.

The new squadron was also a Mosquito Squadron, transferring in from Bradwell Bay. Night patrols had been the order of the day and these continued, and even as the squadron moved into their new home a Do. 17 was intercepted and shot down near Felixstowe.

During the day, personnel took to painting and refurbishing the dispersals, whilst at night patrols continued on, an F.W. 190 falling victim to Flt. Lt. H. Tappin DFC and Fly. Off. I. Thomas in Mosquito S.727

The remainder of the month and into June involved further night patrols,  many being cancelled due to poor weather, whilst on the ground yet more decorating took place, with all crews taking part.

June then saw the temporary arrival of 515 Sqn with Defiants moving in from Heston. On June 1st, all aircraft had been received at Hunsdon with the rear party arriving later by road. As soon as 11 Group Headquarters had been notified of the squadron’s readiness, the order came though to move sections to forward bases ready for night operations. Eight aircraft immediately took off from Hunsdon but poor weather curtailed any further flights and they all returned the next day without taking part. This routine pretty much set the scene the remainder of the month. Shortly after arriving here 515 would start to accept the Beaufighter, a remarkable step up from the Defiant and an aircraft they would take when they left Hunsdon for Little Snoring in December that year.

Then in July, a new version Mosquito began to arrive with 157 Sqn – the MK.VI. ‘Ranger‘ patrols became a priority, attacking freight locos across the enemy network. On the 19th August, the Sqn claimed their 100th victim, a landmark number that was acknowledged by Sector Commander Group Captain Harris.

The next few months were a  mix of sporadic contacts but few engagements, ‘uneventful’ patrols and cancelled flights due to poor weather. The arrival of a Lancaster out of fuel in early October, a Wellington damaged by flak and a lost B-17 possibly heightening the excitement on the airfield.  A large portion of this time was taken with sports including shooting until finally ‘discouraged’ by local landlords.

Remains of the latrines and drying rooms.

157 Sqn however, wouldn’t remain at Hunsdon for much longer, departing with their Mosquitoes for Predannack in November that same year. A relatively uneventful stay at Hunsdon had finally come to an end.

Movements into and out of Hunsdon would continue in November, with the arrival of yet another Mosquito unit, 410 (Royal Canadian Air Force) Squadron. The unit would stay here on three separate occasions throughout 1943 and 1944, each time being for a short period only before moving on again elsewhere. Each stay would bring a new model Mosquito: MK. VI, MK.XIII, and finally the MK.XXX before moving off to the continent in 1944 and their eventual disbandment in June 1945. Whilst the squadron was primarily Canadian (seventy-two personnel), it also consisted of sixteen RAF personnel and four Americans, making it a multinational mix of aircrew, officers and ground crews.

It was whilst at their previous station, West Malling, that they would make the first ‘kill’ of 11 Group, when on the 5th November, a Mosquito piloted by Flg. Off. Green and his navigator Pt. Off. Goodhew, intercepted an Me. 410 and shot it down approximately 15 miles from Dungeoness. Three days later they would arrive at Hunsdon, where a turn in the weather prevented any further kills for the unit for the remainder of the month.

Training flights were managed on the odd occasion, intercepting friendly bombers with camera guns along with several Mahmoud exercises. On the 26th November tragedy struck when on one of these flights Flg. Off. J.J. Blanchfield in Mosquito DD669 struck the target Mosquito DZ259 flown by W.Off. C. James and his navigator Flt. Sgt. T. Levine. Both crews reported that they were bailing out, but both Blanchfield and his navigator Flg. Off. K. Cox, were killed in the accident.

The squadron’s  remaining time at Hunsdon was much similar, training flights, the odd operational scramble and bad weather persisted to the end of the year. But in December, one Mosquito flown by Flg. Off. “Joe” Schultz and Flg. Off. Williams manged to shoot down no less than three Dornier 217s in an epic air battle in which they themselves narrowly missed being the victim.

After vectoring onto the initial target, Schultz managed to shoot it down even though the Dornier tried to evade the attack by both attempting to fly into cloud and carrying out violent evasive movements. After dispatching this aircraft, Schultz pursued a second aircraft which exploded some 50 feet ahead of him, causing his own aircraft to jolt as it passed through the debris. A third Dornier gave a more difficult challenge, and even though both its engines were hit, the crew continued to return fire whilst the pilot made aggressive and violent defensive movements. The Mosquito in return, had its instruments put out of action and both engines hit, causing a fire in one. Luckily, this extinguished itself, but the second engine then failed altogether. Schultz managed to safely land the aircraft at Bradwell Bay using the single damaged engine, a remarkable feat considering the damage to the Mosquito and its components.

During the month, yet another new version Mosquito began to arrive at the squadron in addition to those already on station. By the end of the December, when they finally departed Hunsdon for Castle Camps, they had on their books: two Mosquito MK.IIs, one MK.III, one XII and seventeen XIIIs. A squadron Magister was also registered, but the Oxford they had, had struck a hill severely injuring the pilot, Flt. Lt. M.A. Cybulski DFC at Winter Hill, Belmont near Bolton. Flt. Lt. Cybulski had completed his tour of duty and was transferring to 9 Group when the accident happened.

New years eve 1944 would undoubtedly bring the most significant of the RAF units to Hunsdon and the one for which it is most famous. The arrival of  21 Sqn, 464 Sqn and 487 Sqn combined together to form 140 Wing, would see a number of dare-devil raids against German targets which, like the dams raid of 617 Sqn, would be forever discussed by historians.

The full story of RAF Hunsdon can be read in Trail 25.

RAF Hunsdon – The end of the Turbinlite (Part 2)

In part 1, we saw how Hunsdon was developed and how the new Turbinlite system was developed. However, things don’t quite go to pan the system falls doesn’t meet expectations.

After taking on Hurricanes IIB/C at Martlesham Heath in April, 3 Squadron arrived at Hunsdon from Stapleford Tawney, and like 85 Sqn, would remain here until mid May 1943, when it took its Mosquitoes to West Malling.

Pilots and aircraft of 3 Sqn would make their first appearance at Hunsdon on the 2nd August 1941 when twelve pilots arrived to practice formation flying with crews of the special Havoc Flight created earlier in May. These initial twelve would be followed by another twelve on the third, and then ten more crews on the sixth. The two squadrons would perform practice night flights together, formation flying and ‘dog fighting’ tactics with drogues. By the 10th, the bulk of the squadron had moved over leaving only a detachment both at Manston and Shoreham, where crews undertook both dawn and dusk patrols over southern England and over enemy airfields looking for bombers either landing or taking off.

The combined practice flights would take Hunsdon’s 3 Sqn and the Turbinlite Flights aircrew well into the summer and autumn of the following year, progress being marred by continuing poor weather. GCI (Ground Control Intercept) training and formation flying between the two units took up the majority of the time whilst they were here, however, both dusk and dawn patrols in their Hurricanes gave the pilots of 3 Sqn a little respite from the routine of formation flying with the two Special Flights.

September 1941 then brought the second of the two Special Flights to Hunsdon. On the 20th, 1459 (Fighter) Flight, the penultimate of the ten, was formed here also operating both Havoc Is and Boston IIs, Fs and IIIs. The last of the Flights to make up the ten units would follow just after, being based in northern England at RAF Acklington.

It was quickly found that the Turbinlites not only had a lack of firepower, but poor speed as well, so they were soon demoted to being used solely as a searchlight platform with 3 Squadron’s Hurricanes taking over the main role of interceptor.

With the formation of a new squadron at Croydon, 287 Sqn would have detachments spread far and wide including one here at Hunsdon. Staying here for virtually the entire war, they would fly a range of aircraft including: Blenheims, Hudsons; Lysanders; Hurricanes; Masters; Defiants; Martinets and Spitfires. Even as a detachment flying support flights, they were the longest resident at Hunsdon but never achieved the same status as many of those that were to be based here.

After the turbulence of 1941, 1942 would initially bring a much calmer time at Hunsdon, with less movements in or out of the airfield, although staff changes did cause problems for some units. Changes were initially relatively small, the first of which wouldn’t come until the July of 1942, when a small detachment of 605 Sqn Bostons arrived. After being reformed the month before, at RAF Ford, the small group remained here until mid March 1943, when after taking on the Mosquito, they transferred to Castle Camps in Essex.

605 had previously been posted to Batavia where the majority of ground personnel had been captured by enemy forces. Those that were left were posted to various units and the squadron disbanded. Its reformation at Ford would be a slow process, but gradually it would receive both men and aircraft, accepting machines from 23 Squadron as it also eventually took on the Mosquito.

Whilst based here at Hunsdon, they would primarily carry out training, performing cross country flights,  searchlight co-operation flights and gunnery practice. Navigation also came under scrutiny with logs being examined by the squadron’s navigation officer. By the end of August though, all was well and the personnel returned to Ford thus reuniting the entire squadron once more.

As was the case with many other airfields, training and support flights also used the same airfields, training pilots in new and more modern ways to fly. Hunsdon was no different, and in August a new Flight fulfilling this role was created here at Hunsdon. 1530 Beam Approach Training (BAT) Flight, who were formed specifically to train pilots to land in the dark, or poor weather, using a ‘beam’ (formally blind approach) or radio system. They remained here for some time eventually moving to Wittering where they were disbanded later in 1944.

It would also be in August 1942, that Hunsdon’s resident 85 Sqn would take on the Mosquito, the MK.IIs being a major change from the Havocs previously used. It would only be a trickle of aircraft at first, with just a small number of the ‘Wooden Wonders’ being received by the month’s end.

The trickle continued into September as did the nightly Havoc patrols. On the 7th, Sgt. McCormick sighted what he believed to be a Ju. 88, and closed in for the attack. After following the aircraft he managed to close to 150 feet at which point he opened fire on the starboard engine which quickly caught fire. The aircraft fell from the sky and was later seen burning on the sea below. It was confirmed not as a Ju. 88 but as an He.111 distinguished by its fixed rear-firing machine gun in the extreme end of the fuselage.

September 1942 then brought yet more change. At this point it was decided to raise all ten Turbinlite squadrons to squadron status. The date decided upon was September 2nd 1942. However, due to administration problems, only five could be raised on that date, the remaining five being raised six days later on the 8th of the month. By then, all ten Turbinlite training Flights had been disbanded and reformed as operational squadrons.

With that, 1451 became 530 Sqn on September 8th and continued to operate from Hunsdon, whilst 1459 became 538 Sqn and was relocated to Hibaldstow.

The reformation meant that flights were initially curtailed for 530 Sqn. The poor September weather then added to the issue meaning that flying was at best sporadic. Two further support Hurricanes soon arrived for the squadron taking the total available to four. But their arrival did not ease the situation, the poor weather and other factors continuing to dominate operations to the point that little operational flying took place at all.

October fared little better. More poor weather combined with the fact that three of their four Hurricane pilots (all American), were transferred to the US Army Air Corps, meant that 530 Sqn was unable to progress the way it had hoped. It had been a very poor start for the operational Turbinlites.

By November there were a total of eight Hurricane pilots, some of which had transferred in from O.T.Us, but all were lacking night flying experience. As a result, they were rushed through a night flying course at Hunsdon and were passed as ‘operational’ by the month’s end. However, the problems did not end there. Formation flying in good weather was considered difficult and in visibility of 2,000 ft or less, impossible. This meant that the required number of night flights were not being made which held back all operational flights. Compounding this, continuing bad weather had by now turned the ground very soft and a number of aircraft were getting bogged down in the mud. In addition, whilst aircraft serviceability was generally good, a few had experienced wrinkling of the skin over the air frame and were now awaiting an inspection before being allowed to fly. By now, the crews must have been wanting 1942 to draw to a very quick close.

And to a close it came. December brought rumours of the demise of the Turbinlite squadrons causing uncertainty amongst the personnel. Continuing bad weather had curtailed all but the most urgent of flights. Lectures prevailed bringing escape tactics and Luftwaffe organisation information up to date. A new Havoc was brought in for testing with a new windscreen deicing system, unfortunately this was found unsatisfactory, so a new hot air method was suggested by the squadron and tested under the same conditions. This proved much more successful.

Christmas celebrations then kept the personnel occupied and were ‘livelier than expected’ primarily due to the inclement weather. Crews in the meantime being kept on standby in case the weather turned and operations became necessary again.

The battle headquarters.

With New Year 1943, came the news that the Turbinlites were indeed being disbanded. Of the ten squadrons formed, only five made successful enemy intercepts – Turbinlite was not a great success and as a result, on the 25th January, 530 Squadron along with all other units, ceased to exist and all personnel were scattered amongst other squadrons.

The end of the Turbinlites meant that Hunsdon only had two operational units at this point, both 85 and 3 Sqn continuing to fly from the airfield when they could. The early part of the year, brought considerable fog and cold weather, the fog preventing flying on many occasions, which hampered test flights for 3 Sqn on their new Typhoons when they arrived in February.

By mid May though, both these units were to depart also, 3 Squadron transferring to West Malling, with the Mosquitoes of 85 Sqn joining them soon after, but not until after a very important ceremony.

RAF Hunsdon – The beginnings of Turbinlite (Part 1)

In Trail 25 we head to the south once more, to the west of Harlow, and to two wartime airfields; one of which played a major part in striking a blow at the very heart of the Nazi regime.

The county of Hertfordshire is an area popular with commuters to both London and the technological towns of Harlow and Bishops Stortford. Being north of London, it is also close to Stansted airport, itself an ex World War II airfield. Hertfordshire has some beautiful countryside, delightful little villages and quaint country pubs. It is also an area with a wealth of history.

Our first stop is a small airfield nestled in the heart of this beautiful countryside. It is situated north-east of the village that gives it its name, RAF Hunsdon.

RAF Hunsdon

The Hunsdon Village sign reflects its history and links to the RAF.

Even before Hunsdon was built, it is referenced in some areas that the site was being used for a detachment of 107 Squadron Blenheims, then based at RAF Wattisham and later Leuchars. This may have been part of the ‘Scatter’ directive given to squadrons in the immediate period before war was officially declared, and was thought to occur between May 1939 and March 1941.  However, there are no references to this in the official squadron files and so this action is doubted. However, if this were the case, then it would certainly suggest an early use of the site before it was developed into a fully operational airfield, and it may have been an indication that an airfield was on its way in the near future.

The site was earmarked for development in 1940, with construction occurring over the period October 1940 to March 1941, after which the first squadron moved in. It was built by various construction companies and incorporated two asphalt runways; the main running east-west reaching 1,750 yards in length after its later extension, with a second running north-east to south-west  extended to 1,450 yards; both were built to the standard 50 yard width. Aircraft dispersals, maintenance and storage buildings consisted of eighteen ‘twin-engined’ hardstands; sixteen blister hangars (a mix of ‘Over’ (4) and  ‘Extra Over’ (12)) and a Bellman hangar. There was also a fuel dump and accommodation buildings for up to 2,240 airmen and some 276 WAAFs, all located across eight dispersed sites.

A large number of operational units, (in excess of twenty-five) would pass through its doors throughout its relatively short life, providing Hunsdon with a multinational mixture of crews and a number of aircraft types.

The airfield itself lies within a stone’s throw of London and so its initial role was that of night fighter operations covering London and the south / east area.

The first recognised squadron to make its mark at Hunsdon was 85 Squadron on May 3rd 1941, transferring across from RAF Debden flying Defiants and Havoc MK.Is. The move across on the 3rd went smoothly with personnel and equipment being transferred across in lorries and 32 seat busses, the majority of personnel arriving later that day.

The Parachute store now holds farm machinery.

On arrival at Hunsdon, personnel of ‘A’ Flight were immediately billeted on the aerodrome close to their dispersals, whilst those of ‘B’ Flight were housed on Number 2 Site, located about a mile or so from the main airfield area. Personnel of both the Headquarters Flight and the servicing Echelon were billeted even further away, about four miles in fact, at Gilstone Park. The officers meanwhile, had the better accommodation, being billeted in a house called ‘Boningtons’ believed to be the former home of “Mr. Brooke Bond” the family of the P.G. Tea empire. It is thought that the family purchased the house in 1940, moving out of their London residency to avoid the blitz. Unfortunately, it was rather a short lived purchase as the property was requisitioned by the RAF not long after!

By the end of the 4th, all 85 Sqn personnel were in and unpacked at Hunsdon, and so night flying duties could commence straight away with patrols taking place over the Felixstowe area. Immediately, a Heinkel He.111 was vectored onto, and a skirmish took place in which both aircraft both gave and received machine gun fire. The Luftwaffe bomber came off worst though, and was last seen diving into cloud firing a white verey pistol, either as a resignation of the fight or possibly as a distress signal to any would be rescuers.

Over the next few nights further contacts were made and several Ju. 88s were either confirmed or claimed as shot down. The squadron was performing well, morale was high and all was looking good.

The night of the 13th could have been different for some though. On his return from a patrol, Fly. Off. Hemingway’s instruments failed and with little choice, he gave the order to bale out. After his operator, Sgt. Bailey, had departed the Havoc, Hemingway followed, both men landing in close proximity to each other in the grounds of Much Hadam Hall (a grade 1 listed building built in the early 1700s). Whilst both airmen were safe, Hemingway’s was not the model jump, as he came to rest in a tree in the grounds of the hall. Bailey fared little better, landing rather ungainly on a bucket not too far away. This was Hemingway’s third successful bale out of a stricken aircraft, his previous two both occurring during the Battle of Britain.

On May 17th, Wg. Cdr. Peter Townsend, now with a DSO, flew to Great Massingham, Flt. Lt. Marshall flew to Odiham to test the runway and Flt. Lt. Rabone flew to Heston from where he collected a special and secret Havoc which was to be tested by the squadron. The first flight of this new variant occurred on May 23rd, and was quickly followed by a second aircraft on the 28th, After this, they would then begin testing both aircraft as a new night flying platform.

This particular type of aircraft was the forerunner of what became known as the Turbinlite Havoc, a new design that was the brainchild of one Sidney Cotton.*³

The main runway has been reduced to a track.

With the help of William Helmore, Cotton took out two patents; GB 574970 and GB 574118, each one relating to this new idea. It would be Helmore (an Air Commodore) who would then develop the idea further turning it into what would become commonly known as the Turbinlite system.

Originally designated Air Target Illumination, Cotton’s idea was passed to the Alan Muntz Company, who in conjunction with G.E.C., developed it into what was at the time, the most powerful searchlight in the world, and one that would fit neatly into the nose of a Douglas Havoc, or Boston as it was known in the RAF.

The light was so powerful that it would require a staggering forty-eight batteries each stored in the bomb bay of the aircraft, adding an additional weight to the aircraft just short of 2,000lbs. The light was so strong (1,400 amps) that it would discharge in less than 12 seconds meaning its use was limited to short searches only.

The first full prototype Turbinlite aircraft fitted with the unit was Boston W8254 and was flown by Acting Squadron Leader A. Clouston of 1422 (Night Fighter) Flight formed at Heston on May 12th 1941. The Flight would then operate a number of these aircraft, along with several other types which included the only Turbinlite Mosquito; along with a Defiant, Wellington and Hurricane.

Heston was the home of Airwork, an aviation company set up by two ex-Cambridge students and soldiers of the great war, Sir Henry Nigel Norman and Alan Muntz.  Their vision, was to create the best aerodrome near London, a dream that would cost Norman his life and Muntz to lose his son. Airwork would go through many changes during its life, taking on several Government contracts including a range of flying schools to train RAF pilots throughout the Second World War. These included RAF Digby, RAF Grangemouth, RAF Scone (Perth) and RAF Linton-on-Ouse.

Airwork would themselves modify a further four Bostons, with a further sixteen being modified by the Heston Aircraft Company. A third batch was then developed at RAF Burtonwood, giving a total of nine flights for training and ten operational squadrons comprising just short of 100 aircraft in all.

It was soon realised however, that the Bostons lacked firepower and so the company began to look at the Mosquito as a possible replacement aircraft. Only one Mosquito was modified (W4087, a Hatfield built F.II) at Heston, but this idea, unlike the Boston, failed to progress any further than the prototype stage, and no other aircraft were converted.

The Only Mosquito converted to carry the Turbinlite.*⁵

The Turbinlite project quickly gained pace, but the units wouldn’t be raised to squadron status until September of the following year. In preparation, ten special Havoc flights were created to train crews to operate the aircraft. The first of two, formed at Hunsdon (and the first of the ten) was 1451 (Fighter) Flight on May 22nd 1941. The Flight used several examples that included both Boston IIIs (AL469 and Z2280) and Havoc Is (AE470 and AW405). It also utilised a Cygnet and Tiger Moth for pilot training. By the end of the month, 85 Sqn had flown a total of 505 hours, 482 of them undertaken in Havocs, with 213 of these being on night flights.

On August 9th 1941, 85 Sqn were joined here at Hunsdon by 3 Sqn, one of the original three squadrons to have been formed by the Royal Flying Corp. Created on May 13th 1912, when the Air Battalion of the Royal Engineers was absorbed in to the month old Royal Flying Corps, 3 Sqn joined both 1 and 2 Squadrons as the oldest units to have operated in the RFC. As such, its history is long and very distinguished.

In Part 2 we see how the Turbinlite develops, and how, as the war goes on, the first of Mosquitoes arrive.
