Crash

On this day Blenheims of Bomber Command of the RAF attacked an airport and targets near Zwolle. Initial targets in Germany were not bombed due to cloud cover.

Execpt for one Blenheim (L8866) all other damaged aircrafts of the 18th Squadron would return to their base in Norfolk.

 

Blenheim L8866 of 18 Squadron, West Raynham, detailed for operations in north-western Germany, crashed west of Rotterdam shot down over Maas estuary at 12.10h by a Bf109 flown by Uffz. Gunther Behse of 2./JG 76 after it had been attacked by a second Bf109. This was the first squadron casualty since rejoining 2 Group after the battle of France.

The L8866 was that of pilot I.C.B. Worthington-Wilmer. This Bristol Blenheim had taken off from West Raynham. The unfortunate plane flew low from the direction of Matex-Cub, approximately near the “Wiel” where the municipal garbage dump was of the village of Botlek. The Blenheim crashed at 12.15 hours near the coast of Oostvoorne.


Anton van der Zee, Zwartewaal:: "We had been fishing on the  “Brielseplaat” and rowed towards Zwartewaal. It was low tide and when we reached the dam of “Rales”, between the “Bol” and the “Brielseplaat”, we saw something floating on the north shore that we could not identify. After we had rowed closer, we found that it was a corpse. We thought a German likely to have been killed in Rotterdam. Since there was low tide we could not hang the corpse behind the boat and we therefore decided to warn the Germans, they could pick their own comrade. When I arrived at city hall to inform the police there was German present. After I told him of his friend in the river he started to ask questions about everything. He even wanted us to go with him to retrieve the body. Meanwhile, fellow villager Janus Barnes suggested to retrieve the corpse with his boat.

It so happened that Janus, the police, the German and I went away. After we had found the corpse, we dragged it to Zwartewaal and layed it down in the grass next to the pier. When the German discovered that it was an Allied aviator he had lost all interest. "

The 29-year-old Worthington-Wilmer was buried in the cemetery of Zwartewaal. On July 6 the Germans undertook an attempt to retrieve the crashed bomber which failed.

However, the remains of another dead crew member were removed from the wreackage of the Blenheim. It was Sergeant Maydon. On the night of June to 7 July, he was buried by the Germans in the dunes of Oostvoorne. The place was marked by a cross made of rough wood with the inscription: “Maydon”.

On July 25 his remains were excavated by the people of the municipality Oostvoorne. That same day, Sergeant George Edwin Maydon was buried with military honors at the cemetery of Oostvoorne. The body of the third crew member of the Blenheim, Sergeant JG Stanley, was never found.

On 5th September 1940 Bf.109E-4 Wnr 5454 from 5./JG54 and piloted by Uffz Günther Behse was lost over the North Sea near Southend.

According to The Battle of Britian Then and Now this loss was attributed to F/Lt Ryder of 41 Squadron, however checking the RAF Fighter Command Victory claims of WWII I'm not confident if this is the right match as this was achived in the Sheppey area...

 
According to German records Uffz Günter BEHSE of 5./JG54 went missing in Messerschmitt Bf109E-4 (5353) after combat with RAF fighters south-west of Southend at 14.45 hours (BST).

This places his loss over the Thames Estuary - Isle of Grain area at around the time when seven RAF fighter units reported engagements with enemy fighters over an area spreading from Thameshaven to the Isle of Sheppey. All told they claimed 18 Bf109s destroyed, plus four probables, and another one damaged. This poses a fair degree of challenge for anyone attempting to unravel the combats/claims on this date. However, they could well be advised to concentrate on the claims submitted by No. 303 Squadron.

 

 

 

Plane

Bristol Blenheim
 
 

Originally, the Bristol Blenheim was not created as a bomber or with the RAF in mind. During 1933 Bristol Chief Designer Frank Barnwell announced a proposal for a high-speed light passenger aircraft, the Bristol Type 135. The Type 135 as envisioned as a low-wing monoplane capable of carrying up to eight passengers within an all metal cantilever stressed skin fuselage, powered by two 500 hp (373 kW) nine cylinder Bristol Aquila I sleeve-valved air cooled radial engines. By 1934 work on the design had advanced to the fuselage mock-up stage and it was decided to display the mock up at the 1935Salon Internationale de L'Aeronautique in Paris.

In 1934 Lord Rothermere, who was the owner of the Daily Mail newspaper, expressed a desire to obtain for his personal use, a fast and spacious private aeroplane, for this aviation-minded organisation had then appreciated the potential of what is today called the business or corporate aircraft. Lord Rothermere envisaged his requirements as a fast aircraft that would accommodate a crew of two and six passengers, and it just so happened that the Bristol Aeroplane Company had already drawn up the outline of a light transport in this category, the Type 135.

The new aircraft had been designed originally to be powered by two 500 hp (373 kW) Bristol Aquila I engines which were then under development. The Type 135 had an anticipated top speed of 180 mph (290 km/h) but lacked the range to meet Lord Rothermere's requirements. Frank Barnwell proposed changes that included reducing the fuselage cross section to reduce drag and replacing the 500 hp (373 kW) Bristol Aquila I engines with a couple of 640 hp (477 kW) Bristol Mercury VI radial engines driving fixed pitch four blade propellers. Design work started on the now designated Bristol Type 142 with Lord Rothermere as its principle source of funding. It would cost him £18,500 to complete the aircraft, a large sum even by todays standards. Bristol had learned of government plans to expand the RAF and with the anticipation of possible future contracts decided to fund a parallel design called the Bristol Type 143 as a private venture. The Type 143 featured a longer nose and longer undercarriage doors.

First flown at Filton on 12 April 1935, the Type 142 was to spark off much comment and excitement when during its initial trials it was found to be some 30 mph (48 km/h) faster than the prototype of Britain's most-recently procured new biplane fighter, the Gloster Gauntlet. Named Britain First, it was presented to the nation by Lord Rothermere after the Air Ministry had requested that they might retain it for a period of testing to evaiuate its potential as a light bomber. It had a number change from G-ABCZ to K-7557 and was then moved to Martlesham Heath for RAF trials. It proved so successful that in 1935 the Air Ministry issued Specification B.28/35 for a military version with similar performance. This, then was the sire of the Bristol Blenheim which was to prove an important interim weapon at the beginning of World War II.

Aware of Air Ministry interest in the Type 142, Bristol busied themselves with homework to evolve a military version (Type 142M) of this aircraft, and in the summer of 1935 the Air Ministry decided to accept the company's proposal, placing a first order for 150 aircraft to Specification B.28/35 in September. The new aircraft was very similar to the Type 142, but there had of course been some changes to make it suitable for the military role, primarily to accommodate a bomb aimer's station, a bomb bay and a dorsal gun turret. Little time was lost by either the Bristol company or the Air Ministry, for following the first flight of the prototype, on 25 June 1936, it was moved to Boscombe Down on 27 October 1936 for the start of official trials, with initial deliveries to RAF squadrons beginning in March 1937. In July 1937 the Air Ministry placed a follow-on order for 434 additional Blenheim Mk Is, as the type had by then been named.

Of all-metal construction, except for fabric-covered control surfaces, the Blenheim Mk I was a cantilever mid-wing monoplane, with the wing having Frise mass-balanced ailerons and split trailing-edge flaps. The fuselage nose extended only slightly forward of the engines, and both fuselage and tail unit were conventional light alloy structures. Landing gear was of the retractable tailwheel type. The tailwheel of the prototype had retracted, operated by cables linked to the main landing gear but, wisely, this feature was not carried forward into the production aircraft. The powerplant comprised two Bristol Mercury VIII engines developing 730 hp (545 kW) for take-off with a maximum power rating of 840 hp (626 kW) in level flight, mounted in nacelles on the wing leading-edge, and driving three-blade variable-pitch propellers. Accommodation was provided for a pilot, navigator/bomb-aimer, and air gunner/radio operator. A bomb bay in the wing centre-section could contain a maximum 1,000 Ibs (454 kg) of bombs, and standard armament comprised a 7.7 mm (0.303 in) machine-gun in the port wing, plus a single Vickers 'K' machine-gun in a dorsal turret.
 

Initial deliveries of production Blenheim Mk Is to the RAF squadrons began in March 1937. The first aircraft (K7036) to be delivered, however, crashed upon landing totally destroying the aircraft. The first RAF squadron to receive Blenheim Mk Is was No.114, then based at RAF Wyton, and it was this unit which first demonstrated the new type officially to the public at the RAF's final Hendon Display in the summer of 1937. The Blenheims were to arouse excited comment with their high speed and modern appearance, being launched on their career in an aura of emotion created by the belief that, in an unsettled Europe, the RAF was armed with the world's most formidable bomber aircraft. Production contracts soared, necessitating the establishment of new construction lines by A. V. Roe at Greengate, Middleton (Chadderton) and Rootes Securities at Speke (South Liverpool), both these factories being in Lancashire. Between them the three lines built a total of 1,355 Blenheim Mk Is which, at their peak, equipped no fewer than 26 RAF squadrons at home and overseas, the Blenheim's first overseas deployments being with No.30 Squadron in Iraq and No.11 Squadron in India, in January and July 1938 respectively.

However, by the outbreak of World War II few Blenheim Mk Is remained in service with home-based bomber squadrons, having been superseded in the bombing role by the Blenheim Mk IV, which incorporated the lessons learned from the experience which squadrons had gained in operating the Mk I. But their usefulness was by no means ended, many continuing to serve as conversion trainers and, initially, as crew trainers in OTUs. More valuable by far were some 200 which were converted to serve as night fighters, pioneering the newly conceived technique of AI (Airborne Interception) radar, carrying AI Mk III or Mk IV. The single forward-firing machine-gun was totally inadequate for this role, of course, and a special underfuselage pack to house four 7.7 mm (0.303 in) machine-guns was produced. So equipped, Blenheim Mk IFs scored the first AI success against an enemy aircraft on the night of 2-3 July 1940.

Export versions of the Blenheim Mk I were sold before the war to Finland, Turkey and Yugoslavia, and were also built under licence by these first two nations. In addition, a small number had been supplied to Romania as a diplomatic bribe in 1939, but this proved to be unsuccessful. The result, of course, was that Blenheim Mk Is fought for and against the Allies.

When, in August 1935, the Air Ministry had initiated Specification G.24/35 to find a successor to the Avro Anson for use in a coastal reconnaissance/light bomber role. Bristol had proposed its Type 149. Very similar to the Blenheim Mk I, this was based on the use of Bristol Aquila engines to confer long range with the existing fuel capacity, but proved unacceptable to the Air Ministry. Subsequently renewed interest was shown in the Type 149 for use in a general reconnaissance role, and a prototype was built, by conversion of an early Blenheim Mk I, this retaining the Mercury VIII engines and being provided with increased fuel capacity. The fuselage nose was lengthened to provide additional accommodation for the navigator/observer and his equipment, and this was to be finalised as that which graced the Blenheim Mk IV.

The Air Ministry then had misgivings about the Type 149, fearing that its introduction and manufacture would interfere with the production or urgently needed Blenheims. Instead, the Type 149 was adopted by the Royal Canadian Air Force and with the start of the British Commonwealth Air Training Plan, it was decided to produce a version in this country. Fairchild Aircraft of Longueil outside Montreal was selected to produce them under the Canadian name Bolingbroke. Quickly nicknamed the Boly, the type saw service throughout Canada. The Bristol prototype being shipped to Canada to help in the establishment of a production line. The first Bolingbroke Is had Mercury VIII engines, but after 18 of these had been built production changed to the definitive Canadian version, the Bolingbroke IV with Mercury XV engines, and equipment from both Canadian and US manufacturers. Later variants included a small number of Bolingbroke IV-Ws with American built Pratt and Whitney Twin Wasp Junior (SB4-G) 14-cylinder engines rated at 825 hp (615 kW) for take-off, and a number of Bolingbroke IV-T multi-purpose trainers.

Having blown hot and then cold over the Type 149, there was a sudden renewal of interest, primarily as an interim measure until the Type 152 torpedo-bomber, derived from the Blenheim, should become available. The decision was taken, therefore, to introduce the longer nose and stepped windscreen of the Bolingbroke, and to make provision for longer range by the introduction of increased wing fuel capacity. The Bristol designation Type 149 was retained for this changed configuration, the new RAF designation being Blenheim Mk IV. This change took place quietly on the production lines towards the end of 1938, although the first 68 Blenheim Mk IVs were built without the 'Iong-range wing'. The powerplant comprised two more powerful Mercury XV engines, and these allowed gross weight to be increased eventually by 16 per cent.

No. 90 Squadron was the initial unit to be equipped with Blenheim Mk IV s in March 1938, the first of more than 70 squadrons to operate these aircraft, and consisting of units from Army Co-operation, Bomber, Coastal, Far East Bomber, Fighter and Middle East Commands, both at home and overseas. Inevitably, such extensive use brought changes in armament and equipment, but especially the former, for the armament of the first Blenheim Mk IVs was unchanged from the initial two-gun armament of the Mk I. As finalised the number became five, the single forward-firing gun in the wing being retained, a new dorsal turret carrying two guns being adopted, and a completely new remotely-controlled Frazer-Nash mounting being added beneath the nose to hold two aft-firing machine-guns. Protective armour was also increased, but while it was not possible to enlarge the capacity of the bomb bay, provision was made for an additional 320 Ibs (145 kg) of bombs to be carried externally, under the inner wings, for short-range missions.

With so many squadrons operating the type it was inevitable that Blenheims should notch up many wartime 'firsts' for the RAF. These included the first reconnaissance mission over German territory, made on 3 September 1939. It was flown by Flying Officer A Macpherson in a Blenheim (N6215) Mk IV of No. 139 Squadron while on an armed reconnaissance over German warships at Heligoland Bight (Schillig Roads) near Wilhelmshaven. On 4 September 1939, ten aircraft from Nos. 107 & 110 Squadrons, led by Flight Lieutenant K.C. Doran of No. 110 Squadron made an attack on the same German ships. From the beginning of the war, until replaced in home squadrons of Bomber Command by Douglas Bostons and de Havilland Mosquitoes in 1942, Blenheim Mk IVs were used extensively in the European theatre. Although vulnerable to fighter attack, they were frequently used for unescorted daylight operations and undoubtedly the skill of their crews and the aircraft's ability to absorb a great deal of punishment were the primary reasons for their survival, for high speed and heavy firepower was certainly not their forte. In the overseas squadrons Blenheims continued to serve long after their usefulness had ended in Europe, and except in Singapore, where they were no match for the Japanese fighters, they proved a valuable weapon. A total of 3,298 Mk IV had been built in England when production ended, and in addition to serving with the RAF had been used by the French Free and South African air forces, and supplied in small numbers to Finland, Greece and Turkey.

Last of the direct developments of the Blenheim design was Bristo1's Type 160, known briefly as the Bisley, which was to enter service in the summer of 1942 as the Blenheim Mk V. Envisaged originally as a low-altitude close-support bomber, it was in fact to be built for deployment as a high-altitude bomber, powered by Mercury XV or XXV engines. Except for a changed nose, some alterations in detail and updated equipment, these aircraft were basically the same as their predecessors. Some 942 were built, all produced by Rootes at their Speke (South Liverpool) and Blythe Bridge (Stoke-on-Trent) factories, and the first unit to receive Blenheim Mk Vs was No.18 Squadron. The type was to equip six squadrons in the Middle East and four in the Far East, where they were used without distinction. This resulted from an increase in gross weight of over 17 per cent which, without the introduction of more powerful engines, had brought about a serious fall of performance. It only when the Blenheim Mk Vs were deployed in Italian campaign, contending with the advanced fighters in service with the Luftwaffe, that losses rose to quite unacceptable proportions, and the Blenheim Mk Vs withdrawn from service.
 

Canadian Bolingbrokes

Operational use of the Bolingbroke was limited to the Royal Canadian Air Force in Canada and the Aleutian Islands. No 8 (Bomber Reconnaissance) Squadron was the first RCAF unit to convert to the Bolingbroke, followed by one other squadron. Bolingbrokes were used primarily to fly anti-submarine coastal patrols over both the Atlantic and Pacific.

Two RCAF squadrons were assigned to the combined American-Canadian defence campaign to protect the Aleutian Islands and west coast of Alaska from Japanese attack. No. 115 Squadron arrived in the Aletuians in April of 1942 and was assigned anti-submarine patrol and maritime reconnaissance missions. In June of 1942 No. 8 Squadron deployed to the Aleutians with twelve Bolingbroke Mk IVs, making a 1,000 mile flight from RCAF Sea Island to Yakutat Island arriving on 3 June. When the squadron arrived it was ordered to paint out the Red centers to the upper wing roundels to prevent confusion with the Japanese 'meatball' insignia. Later additional recognition markings in the form of a fourteen inch Blue band was added to the rear of the fuselage. The harsh weather in the Aleutians proved a worse enemy than the Japanese and a number of Bolingbrokes were lost when thick Alaskan fogs obscured mountain tops. Normal bomb loads consisted of three 300 pound depth charges and two aircraft were maintained in an alert status at all times. The squadron is credited with sharing one submarine kill with the US Navy. A Bolingbroke Mk IV piloted by Flight Sergeant P.M.G. Thomas attacked and damaged a Japanese submarine enabling US Navy surface units to later sink it.

The majority of Bolingbrokes produced never saw combat, instead they performed as crew and operational trainers under the Commonwealth Air Training Plan, training crews for overseas units. Still others were converted to unarmed target tugs with high visibility paint schemes for training air gunners and army anti-aircraft gunners.

Unit

No. 18 Squadron was a medium bomber squadron that spend a large part of the Second World Wars overseas, starting in France in 1939-40 and then serving on Malta, in North Africa, in Sicily and in Italy.

Up until May 1939 the squadron had been equipped with the Hawker Hind. It then received the Bristol Blenheim Mk I, the start of a relationship with the Blenheim that would last until the spring of 1943.

At the outbreak of the Second World War No. 18 Squadron was sent to France as part of the Air Component of the BEF. There it took part in the first ten days of the disasterous campaign of May 1940, before retreating to Britain.

This was followed by the squadron's wartime stay in Britain, lasting for seventeen months. During this period the squadron was engaged in attacks on the German invasion barges during 1940, before "leaning over the channel" in 1941 to attack German installations.

In October 1941 the squadron's aircraft flew to Malta, where they took part in raids against Axis shipping. By January 1942 the squadron was down to five aircraft, and was withdrawn to Egypt.

The squadron then reformed in Britain with new aircraft and new crews but many of the same ground crews. Most of 1942 was spent in Britain, before the squadron was moved to North Africa, in November.

The squadron remained in the Mediterranean theatre for the rest of the war, accompanying the Allied armies as they advanced from Algeria to Tunisia, across to Sicily and then finally to Italy. While based in North Africa, the squadron was re-equipped with the Boston bomber. While based in Italy, the squadron was used against targets in northern Italy and the Balkans.

18 Squadron: With Courage & Faith by Gary Parsons

Although not at Wattisham for very long, 18 Squadron is one of the few that is still active today.

Northolt was the site for the birth of 18 Squadron on 11 May 1915, which was formed from Nr 4 Reserve Squadron. A brief move to Norwich (Mousehold) for training was made on 16 August, the squadron acquiring a gamut of aeroplanes such as Bristol Scouts, Shorthorns and Martinsydes but eventually was sent to the Western Front and the horrors of the Great War flying the Vickers FB Gunbus. Flying tactical reconnaissance missions, it saw action over the trenches of the Somme flying from bases such as St Omer, Bertangles and Auchel. DH4s were provided in 1917 and DH9As shortly before the war's end. Disbandment came on 31 December 1919 at Weston-on-the-Green.

The first of many reformations for the squadron came on 20 October 1931 when two Hawker Harts were supplied to the fledging unit at Upper Heyford in Oxfordshire. Forming the backbone of the RAF's light bomber fleet in the thirties, the Hart was to be a common sight in the Oxford skies for the first half of the decade, especially so in the colours of 18 Squadron. Hinds replaced the Harts in 1936, hardly a giant leap in capability, but were to remain in service for two years before Blenheims were available. At this time a brief move to Bircham Newton in Norfolk was made, but by September of that year the squadron was back at Upper Heyford. At Bircham 'C' Flight was detached to Worthy Down to form the nucleus of 49 Squadron.


The start of the war saw 18 Squadron provide aerial reconnaissance over France for the British Expeditionary Force, flying from an airfield near Amy. Such was the devastating effect of the Battle of France that most of the squadron was lost in those frenetic months, the unit being withdrawn to England in the early summer of 1940. Returning to Lympne in Kent, the surviving Blenheims were quickly dispersed to less vulnerable locations, most going to Watton in Norfolk.

Reformed at Gatwick (yes, now the airport) and equipped with Blenheim IVs, coded 'WV', the squadron moved to West Raynham on 12 June, staying here for three months before moving all of a mile to the nearby satellite airstrip of Great Massingham. The first squadron to use Massingham, from here the unit flew night missions against enemy airfields and also provided diversionary raids for the heavy bomber fleet. In April '41 it moved to north Norfolk and another rudimentary airfield at Oulton, satellite airfield for Horsham St Faiths. From here and the parent airfield, still using the redoubtable Blenheim, by now the Mk IV, tactics changed to the anti-shipping role. Detachments were sent to Manston for Operation Channel Stop as with other light bomber units, and during this time on 19 August the squadron made a 'humanitarian' mission by dropping a new metal leg to the captured Wing Commander Douglas Bader in St Omer! Carried by Blenheim R3843 WV-F, naturally enough this mission was titled 'Operation Leg'.

In July, the squadron departed for pastures new in the beautiful island of Malta to bolster the defence of the beleaguered population but returned to Oulton in the November, for rest and recuperation. A month later came departure for Wattisham, although the squadron was somewhat depleted with some crews still in the Mediterranean. As mentioned before, its stay at Wattisham was brief as by August 1942 it had moved back to Great Massingham. Provided now with Blenheim VDs (commonly known as the Bisley), it left for the Middle East in October.

Algeria was the destination, from here the squadron mounted raids on German targets in Tunisia but suffered heavy losses in the early daylight missions. A switch to night missions was made and also a change of aircraft, from the Blenheim to the Boston III. A move to Sicily in August 1943 and onwards into Italy in October saw the squadron see out the war mounting raids on Northern Italy and the Balkans from bases such as Brindisi, still in use today. Immediately after VE day the squadron moved to Aviano, where today much military action is seen, then post-war it moved to Hassini in Greece, where disbandment came on 31 March 1946.
