The Cadillac of the Skies

 

On August 17th, 1943 the Eighth Air Force had tried to eliminate the ball-bearing factories at Schweinfurt, deep inside the German heartland. Flying in daylight, and unescorted for the vast majority of the trip, the raid had been an audacious catastrophe. Some 230 bombers had taken part, and sixty of these were completely destroyed. As well as these sixty B-17s, a further 55-95 bombers were badly damaged. Many of these were too severely damaged ever to be repaired.

Living legends

The Eighth Air Force regained its composure, made good its losses in both men and aircraft, and, on October 14th 1943, they attacked again.  Flying in daylight, and unescorted for the vast majority of the trip, the raid was arguably a bigger disaster than the previous one. Of the 291 B-17s on the mission, 60 were shot down over enemy territory and another 17 damaged so severely that they had to be scrapped. A further 121 aircraft were damaged to a greater or lesser extent. These losses represented more than 26% of the attacking force.

The losses of aircrew were equally devastating. Some 650 well trained and skilful specialists were killed, which constituted some 22% of the 2,900 brave young airmen who went on the raid. The 306th Bomb Group lost 100 men, with 35 either killed in the air or died of wounds and 65 made Prisoners of War. The 305th Bomb Group lost 130 men, which was 87% of their complement.
General Henry H. “Hap” Arnold was later to state that the Black Thursday loss of American bombers in the Schweinfurt raid was “incidental”. Despite this callous dismissal of the lives of well over six hundred of his own men, further unescorted daylight bomber raids deep into Germany were immediately suspended until further notice. Cynics might well ask how many more B-17s  were left after the two disastrous attacks on Schweinfurt? Long distance bombing raids would only recommence in February 1944 with the advent of Operation Argument, a series of missions which would later be more commonly known as “Big Week”.

I live in Sherwood, a suburb in the north of the Nottingham conurbation in England. At the end of our street is “Hucknall Road” which leads the seven or so miles to the much smaller market town of Hucknall.

Strangely enough, Hucknall has a small grass airfield which is less than six miles from our street. Most days we can hear light planes making an enormous noise as they drone slowly overhead.

Hucknall RunwayxxxxxxDuring the course of April 1942, one man who frequently worked at Hucknall Aerodrome was to come up with an idea which would go a very long way indeed to winning the war in Western Europe. His name was Ronald W. Harker and he was usually known as “Ronnie”. Harker was the senior liaison test pilot with Rolls-Royce. Perhaps with Harker’s employer in their minds as an ulterior motive, the RAF had already invited the experienced test pilot to test fly the North American Mustang Mark 1, an American aircraft which was designed and built in the unbelievably short time of 117 days. This amazing feat was in response to a request by the British Purchasing Commission for an RAF fighter which would be an advance on the Spitfire.

The original North American Mustang was powered by an Allison V-1710 piston engine and Harker was quite impressed with the plane’s handling qualities. Its performance up to 20.000 feet or so was commendable, but any higher, and the aircraft quickly became rather disappointing. Harker concluded that the problem was the inadequate Allison engine which was too low-powered to exploit the plane’s advanced aerodynamic features including a much more fuel efficient laminar flow wing. This innovation cut down the amount of turbulence as the air passed over the wing and would eventually lead to almost phenomenally low fuel consumption.

Initially though, the new American fighter had an extremely unimpressive maximum range of only 400 miles, and when delivered to the RAF it was quickly relegated to Army co-operation and photographic work.
Ronnie Harker was employed by Rolls-Royce and was therefore presumably somewhat biased, but it was his suggestion to take out the Allison engine and to replace it with the Rolls-Royce Merlin 61, an act which was to transform a rather disappointing aircraft and to turn it into a war winner.
Despite a great deal of initial reluctance, mostly from the British Air Ministry, the first flight of the newly engined Mustang took place at Hucknall Airfield on October 13th 1942 with Captain R.T. Shepherd, the Rolls-Royce chief test pilot, at the controls. The Merlin-Mustang fighter’s performance was spectacular, particularly at high altitude. Thus the greatest fighter of the war was born and Harker acquired for the rest of his life the sobriquet of “the man who put the Merlin in the Mustang.” Harker also got a pay rise of a pound a week (just over one and a half dollars).

Some four hundred of the Merlin-Mustangs were ordered for the US Army Air Force as the P-51 and Great Britain wanted more than a thousand, although only 25 were eventually delivered to the RAF because Rolls-Royce’s own Merlin production was already allocated to Spitfires, Lancasters and Mosquitos. In the USA, however, North American, now almost overwhelmed by the orders to be filled, had no such problems, using Packard and Continental versions of the Rolls-Royce engine built under licence. Eventually, more than 15,000 aircraft were to be manufactured.

P-51_Mustang cccccccc
The P-51B carried just about the same amount of fuel as the P-47 Thunderbolt, but with its new Merlin engine “got 3.3 miles per gallon while the P-47 got less than 1.8.”. Brigadier General “Tommy” Hayes said that the Merlin-Mustang “had the three qualities you need most if you were going to escort bombers to Berlin – range, range and range.” The latter was extended even further by the carrying of two 512 gallon drop tanks which gave a maximum range of around 2,000 miles. In addition, the aircraft’s top speed increased from 390m.p.h. to 440m.p.h. and in the days after the war had finished there were to be many no doubt apocryphal tales of Mustangs which had exceeded the sound barrier in a steep or even vertical dive. In his memoirs, the P-51 ace Colonel Clarence E. “Bud” Anderson said that the Mustang “went like hell” because “the Merlin had great gobs of power and was equally at home high or low, thanks to its two-stage, two-speed supercharger.”

This newly updated Mustang was, of course, exactly the aircraft that the beleaguered bomber crews in the B-17s of the Eighth Air Force had been waiting for. Now, with help of “our little friends” they could go about their business with considerably less apprehension than had previously been the case. The new aircraft is certainly said to have had an impact on Herr Reichsmarschall Göring who “when (he) saw the Mustangs escorting the American air armadas over the capital of the Reich is said to have realised that Germany had lost the war.”

little friends cccccc

The mechanism by which the Third Reich was, along with Göring himself, quite rightly consigned to the rubbish bin of History, was by no means a complex one. The Mustang pilots were quite simply encouraged to engage the Luftwaffe fighters in combat at every opportunity.  Given the quality of the new P-51, especially the P-51D with its superb all round visibility bubble canopy, the Americans duly shot down both the aging Bf109s and the newer Fw190s. Gradually over the months, the Mustangs killed off all the most experienced and most effective pilots in the Luftwaffe. Between January and April 1944, the Germans lost more than 1,000 fighter pilots, of which 28 had more than 30 kills and eight had more than 100. On one mission to Augsburg, much later in the war, Mustangs put a final full stop to the last and greatest German threat, namely the twin-engined fighter armed with multiple rockets. They destroyed 23 of the 77 that came up to oppose them.

At the same time, as part of the same process, it became increasingly difficult for the Luftwaffe to find calm skies where rookie pilots might practice. And in any case there was soon too great a shortage of fuel for these young replacements to waste on practice flights. The situation swiftly went from bad to worse, and the Mustangs, and many other Allied fighters, all began to enjoy enormous success against increasingly weak opponents. The Germans were never ever throughout the rest of the war to enjoy air superiority.

Allied bombers began by day and by night to operate with increasing impunity and to have an increasingly greater impact on the overall fighting capabilities of the Third Reich.

The situation is perhaps best summarised by a joke which remains as yet unverified on Wikipedia. It was supposedly told by Wehrmacht soldiers in the weeks after D-Day:

“If the plane in the sky is silver, it’s American, if it’s blue, it’s British, if it’s invisible, it’s ours.”

“This all happened because of the Mustang, and the Mustang succeeded because of the Merlin.”

I cannot resist finishing my hymn of praise to the most effective fighter ever by quoting the episode in “Empire of the Sun”, when the “Cadillac of the Skies” makes its appearance, strangely not in Europe but in China. Enjoy.

Schweinfurt Two: sixty B-17s downed, 650 airmen killed

I hope that you were able to read my blog post about the American Eighth Air Force’s first raid on the ball bearing factories at Schweinfurt. This brave action took place on August 17th 1943, and was a catastrophe. As I wrote a few weeks ago…

“The raid caused a 34 per cent loss of production at Schweinfurt but this was soon made up for by surplus supplies from all over Germany The industry’s infrastructure, while vulnerable to a sustained campaign, was not vulnerable to destruction by a single raid.”

I quoted the casualty figures…

“230 bombers had taken part, and sixty of these were destroyed. Five hundred and fifty two men were killed in the air, and seven poor souls made it back home, but, alas, had already succumbed to their injuries. Twenty one men were badly wounded. Beyond the sixty B-17s shot down, between 55-95 further aircraft were badly damaged. Of these many were too severely damaged ever to be repaired.”

Despite these huge losses, the Eighth Air Force plan had always been to go back to Schweinfurt a second time. It was to take the best part of two months to rebuild their forces, but on October 14th 1943, the B-17s returned to attack the factories where, at the time, American wartime intelligence thought ball bearing production had been permanently reduced by up to a third.
This time, changes would be made. Instead of a two-pronged attack on the ball-bearing works at Schweinfurt and the Messerschmitt aircraft works at Regensburg, the entire force would attack Schweinfurt alone.

Secondly, additional fighter escorts were added to protect the vulnerable bombers as much as was possible during both the outward and return journeys of the operation. Each of the three bomber wings, therefore, was to be escorted by multiple squadrons of P-47 Thunderbolts. For an unknown reason, though, none of the P-47s were equipped with drop tanks, an important mistake which significantly limited their escort range. And one outfit of fighters previously allocated to the Flying Fortresses was given the job of acting as an escort to the 29 B-24 Liberator bombers on a diversionary mission to Emden.

At first, though, things went quite well. When the bombers were initially intercepted as they crossed the coast the P-47s succeeded in shooting down seven Bf 109s. But over the Netherlands the P-47s came to the end of their range and the B17s were left alone and virtually defenceless.  Large numbers of Focke-Wulf FW 190s and Messerschmitt Bf 109s  made repeated attacks exactly as they had done in August. The 305th Bomb Group lost 13 of its 16 B-17s in just a few minutes. Further into Germany, this second Schweinfurt Raid would soon follow the same pattern as the first one.

As well as single engined fighters, twin engined Messerschmitt Bf110s and Junkers Ju88s were encountered. They carried much heavier cannon.

This time, many more aircraft were armed with Werfer-Granate 21 rocket launchers, firing unguided stand-off rockets.

Here are two wonderful pictures from the Life Magazine of  the day, showing the heroic efforts of the brave young Eighth Air Force gunners.

As in August, although the ball-bearing factories were badly hit, the mission did not achieve any long lasting effects. Ball bearing production was halted for around six weeks but these losses were again easily made up by the large stocks the Germans already had. After this second attack, all of the ball bearing facilities were dispersed from Schweinfurt across the whole of Germany to reduce the risk of their being bombed for a third time.
General “Hap” Arnold claimed that “Black Thursday” and its losses were just incidental, but daylight bomber raids deep into Germany without fighter escort were suspended until further notice. Cynics might well have asked just how many B-17s did the Eighth Air Force have left on strength anyway?
Long distance bombing raids would only recommence in February 1944 with the advent of Operation Argument, a series of missions later to be called the “Big Week”. By then, escorts were available in the form of P-51B Mustangs.

Arnold’s “incidental losses” on the second Schweinfurt raid were astounding. Of the 291 B-17s on the mission, 60 were shot down over enemy territory.

Another 17 bombers were damaged so heavily that they had to be scrapped. A further 121 B-17s were damaged to a greater or lesser extent and many of the crippled bombers would require a great deal of time and effort to repair them.

These B-17 losses represented more than 26% of the attacking force. The losses of aircrew were equally devastating, with 650 men killed out of 2,900, some 22% of the bomber crews. Certain units were hugely affected. The 306th Bomb Group lost 100 men, with 35 either killed in the air or died of wounds and 65 made Prisoners of War. The 305th Bomb Group lost 130 men with 36 killed outright. This constituted 87% of their complement.

My own father, Fred, even if he seems never to have had a great deal of contact with the Americans of the Eighth Air Force, always had enormous respect for their almost unbelievable bravery. Some thirty years after the war, as I returned from university, Fred was to accompany me, one dull autumn day, on a visit to the American Cemetery at Madingley near Cambridge.

How strange to think that these neatly kept graves may well have been the last resting place of some of the brave young airmen he had watched flying high above him in the frosty blue sky of East Anglia so many years previously.

If your navigational skills are up to it, this is Part One of a ten film series about  the Schweinfurt raid.

In another blog post, I will look at what the Eighth Air Force did after the two disastrous raids on Schweinfurt, and how their airmen’s lives were saved, and arguably the Second World War was won, thanks to Ronnie Harker, a New Zealander who at the time was working at Hucknall in Nottinghamshire, just six miles to the north west of where I am sitting right now as I write the conclusion to this post.
