RAF Polebrook – The First USAAF Bombing mission (Pt 1).

At the top of Northants, close to the Cambridge / Huntingdon borders, lie a number of wartime airfields. Relatively high up, they can be bleak and windy, but to those interested in aviation history they offer some amazing stories and fascinating walks. Some of these sites have been covered in earlier Trails e.g. Kingscliffe, Deenethorpe, Spanhoe Lodge and Grafton Underwood, but because of their close proximity, they could all be combined with this trip.

Our visit today in Trail 19 is the former RAF Polebrook, home to the famous Clark Gable, and the site that saw the very first official Eighth Air Force Bombing mission in August 1942.

RAF Polebrook (Station 110)

To the west of Peterborough, across the A1 and through some of the most gorgeous countryside this area has to offer, is Polebrook, a small village that once bustled with the sound of military voices. Originally designed for the RAF’s Bomber Command, Polebrook opened in May 1941, as a Class II airfield built by George Wimpey and Co. Ltd. It had three runways, the main one being (08-26) 1,280 yards in length, with two further runways (14-32) of 1,200 yards and (02-20), 1,116 yards, giving the site a substantial feeling of size. To accommodate the dispersed aircraft, it was designed with thirty hardstands laid mainly to the south-west and eastern sides of the airfield. The administration and technical sites were located to the north.

Aircraft maintenance was carried out in two type T2 hangars and one J type hanger, which sat next to each other, there were in addition, a range of technical buildings, a Watch Office (with Meteorological Section to design 518/40, to which a circular addition was made to the roof) and around 20 pill boxes built to provide defensive cover of the overall site.

To the north of the site across the main road, lies an area known as Ashton Wold Woods. Within the wood is the Ashton Estate, which was purchased and developed by the banker, Lionel Rothschild in 1860. It was after this that the estate was developed into a country home for his grandson, Charles Rothschild.

Charles, a banker by trade, set about creating a formal garden on the estate along with his wife Rozsika, and later his daughter Miriam. He had the grand honour of being the country’s leading expert on fleas, as well as a naturalist and conservationist who was responsible for forming the Society for the Promotion of Nature Reserves in 1912.

After his death and subsequently Rozsika’s in 1940, the house passed to their daughter, but when the construction of the airfield began, the house and gardens were requisitioned for use as both as a hospital and accommodation site. During the war, the site suffered badly through neglect, and post war, Miriam set about restoring parts of the estate. Sadly it was not fully restored and parts continued to fall into disrepair*1.

A year after Miriam inherited the estate, the first RAF unit arrived, No 90 squadron (28th June 1941) with Fortress Is, otherwise known as Boeing’s B-17C, who stayed until their disbandment in February 1942. Although liked by their crews, the Fortresses were dogged by high altitude problems (freezing guns) and poor bombing results. This early version of the B-17 was not to be a record breaker and had a relatively short life before being replaced later by better models. Between 8th July and September 2nd, 1941 Polebrook Fortresses made 22 daylight attacks against targets including: Wilhelmshaven, Bremen, Brest, Emden, Kiel, Oslo, and Rotterdam. The RAF eventually decided to pull out of these daylight raids and the airfield momentarily fell silent to operational activities.

Polebrook airfield was then handed over to the USAAF (June 28th 1942) and re-designated Station 110. It was felt however, that the current runways were inadequate for the American’s new model B-17s, and so a period of expansion then occurred. During this time the hardstands were increased to 50, the main runway (concrete and tarmac) was extended to 2,000 yards and the two secondary runways were both extended to 1,400 yards. Accommodation blocks were increased now allowing for 2,000 personnel, and the whole site was brought up to Class A standard; all-in-all it was a major redevelopment of the entire site.

The first American units were those of the 97th BG of the 1st Combat Wing. The 97th were constituted on 28th January 1942 and activated in the following February. Passing from MacDill Field in Florida through Saratosa they would make their way across the northern route to Prestwick. On route to their departure points, elements of the group were detached and sent to the Pacific coast, whilst the remainder continued on to Europe. The first manned B-17 #41-9085, ‘Jarrin Jenny‘ arrived in the UK on 1st July 1942 touching down at Prestwick in Scotland after a 3,000 mile long flight via Greenland, with the first ground echelons arriving via the Queen Elizabeth, shortly before on 10th June. Five days after ‘Jarrin Jenny’s‘ arrival, the aircraft would reach their new base, and the Northampton countryside would become a buzz of activity, as much from the curious locals as the Americans they were in awe of.

Almost immediately after arriving int the UK the four squadrons of the 97th were split. Between June and the end of November the Headquarters unit, along with the 340th BS and 341st BS were based here at Polebrook, whilst the 342nd and 414th BS went to the satellite airfield at nearby Grafton Underwood (Trail 6).

Within a month of arriving on August 17th, the 97th BG would enter service flying the first operational mission of the USAAF from England, under the control of the Eighth Air Force. However, hastily formed, these early groups of bombers were made up of poorly trained crews, many of the gunners never having fired their guns at moving targets, nor had pilots flown at high altitude on Oxygen or in close formation. Such was the rush to get the aircraft overseas, that basic radio, flying and gunnery skills were all lacking, and if they were not to become easy targets for the more experienced and ruthless Luftwaffe, then they were going to have to endure a very steep learning curve indeed. Thus the early part of August was to be filled with intensive flying practice, with the RAF offering their services as mock enemy fighters, trainers and advisers, supporting the Americans through the tough training regime that would hopefully save their lives in the coming weeks and months.

By the 9th August it was decided that the 97th was combat ready and orders came through for their first mission. Sadly the 10th August brought poor weather, and the mission was scrubbed much to the disappointment of the those in the Group.

Two days after this, even before a bomb was dropped in anger, the dangers of flying in cloudy European skies would become all too apparent when a 340th BS, B-17E #41-9098 ‘Big Bitch‘ (not to be confused with #41-9021 ‘The Big Bitch’, which transferred to the 390th BG at Framlingham and was renamed “Hangar Queen“), collided with mountains in Wales whilst on a navigation exercise to Burtonwood, killing all eleven on board. The 97th were now racking up many ‘firsts’ adding the first B-17 fatalities to their extending roll.

August 12th saw the next call to arms, but again the weather played a cruel joke on the men of the 97th, the mission being scrubbed yet again; it was beginning to appear that someone was playing a rather frustrating joke at the expense of the eager young men.

Their next mission, detailed on the 16th was then again called. This time was ‘third time lucky’ and the following day the first official mission of the Eighth Air Force was given the green light. At 15:12 six B-17s in two waves of three left the runway at Polebrook and history was made. After rendezvousing with their ninety-seven RAF Spitfire escorts, they headed for the French coast only to turn away and head for home when just ten miles from the enemy’s coast. This time it was not the weather at fault, the mission was a planned feint to tease the Luftwaffe away from the main force following behind – a group of Twelve B-17s from each of the 342nd, 414th and 340th BS.

This mission was not only the USAAF’s first mission, but it also saw the testing of new electronic counter-measures equipment. Flying alongside this formation were nine Boulton Paul Defiants carrying the counter-measures equipment. Code named “Moonshine“, the equipment consisted of ‘repeaters’ designed to repeat back to the German’s their own radar signals thus giving the impression of a much larger and more formidable force.  These first two Polebrook flights split, the first making their feint toward Alderney, whilst the second force flew toward Dunkirk, it was this flight that was accompanied by the nine Defiants. Before reaching the coast though, they turned and headed for home their job done. It was reported by the British that an estimated 150 Luftwaffe fighters rose up to meet the ‘massive’ force, but no interception took place and all aircraft returned to base.

Amongst the main force following on, were three of the Eighth’s most prestigious personnel; the Group’s Commander Colonel Frank Armstrong Jnr who sat beside Major Paul Tibbbets (Tibbets was to go on and drop the first Atomic bomb on Hiroshima thus ending the war with Japan) in ‘Butcher Shop‘; whilst in the second wave flew General Ira Eaker, Commanding General of the entire Eighth Air Force, in ‘Yankee Doodle‘. Bombing results were ‘good’, the clear skies proving to be the bombardiers best friend that day. All aircraft returned, the only casualty being a pigeon that hit the windshield of one of the B-17s as it approached Polebrook. The first mission was over, the ice had been broken.

This first mission, a trip to Rouen, preceded several attacks across the low countries, until in the November when the Group (previously assigned to the Eighth on September 14th) transferred to the Twelfth Air Force. They were now heading for  North Africa. Over the period 18-20th November the air echelons departed Polebrook heading for Hurn before flying on to North Africa. The Ground echelons left shortly after, a point at which the 97th’s connection with Polebrook ceased leaving nothing but a legacy behind.

In the short time the 97th stayed at Polebrook they would complete 14 missions over occupied Europe, dropping 395 tons of bombs. They would then go on to earn themselves two Distinguished Unit Citations and complete a number of ‘firsts’ whilst operating in the Middle East. But with the 97th now gone, Polebrook airfield would enter a period of relative calm and peace.

Then in April / May 1943, Station 110 once more resonated with American voices, with the arrival of the 351st BG. Another new Group, they were initially assigned to the 1 Bombardment Wing (1 BW) of the 101 Provisional Combat Bomb Wing (101 PCBW). After the USAAF went through periods of change and renumbering, this eventually became the 94th Combat Wing, (1st Bombardment Division). The 351st operated with B-17s of the: 508th (code YB), 509th, (code (RQ), 510th, (code TU) and 511th (code DS) Bomb Squadrons, distinguished by a triangular ‘J’ on the tail.

A film taken at Polebrook showing a number of aircrew and aircraft of the 351st BG. Several views of the technical and accommodation sites give a good contrast to the views of today, especially the ‘J’ type hangar that appears above.

The 351st were only activated in the previous October, and were, as ‘rookies’, to take part in some of the most severe aerial battles in Europe. Luckily for them though, training programmes back home had improved, and the gaps that were present in the first crew selections had now been filled.

As with all units new to the theatre of war, a short time was spent on familiarisation and formation flying techniques. Shortly before the 351st were deemed combat ready they were practising formation flying over Polebrook when tragedy struck.

Former Washington Redskins player Major Keith Birlem (508th BS) was piloting B-17 #42-29865 ‘YB-X’ when the plane dropped down severing the tail of another B-17 #42-29491 (509th BS) piloted by Capt Roy Snipes. Both aircraft fell from the sky landing as burning wrecks near to the perimeter of the airfield. The accident took the lives of all twenty airmen on-board the two aircraft. Major Birlem had flown his one and only combat mission just three days earlier, on his birthday, gaining experience as a co-pilot with the 303rd BG who were stationed at Molesworth.

In part 2 we see how the 351st entered the European conflict along with the further development and subsequent rundown of Polebrook immediately after the war. We also look at how the increase in tension of the Cold War brought Polebrook back to life once more, and how it eventually closed for good leading to the condition we find it in today.

  1. Yes, another marvellous account. I always think that the Americans suffered so much from the fact that every aircraft downed might well be ten or twelve casualties. That doesn’t detract, though, from the amazing courage they showed.
    On a lighter note, just in front of the J-type hangar, can you see that the farmer has started work on a couple of V-1 launching ramps? Aimed towards Norfolk and Alan Partridge, no doubt.
