Chaps,
A question that I’m sure any true researcher of Bomber Command will be interested in, “should AM Harris have been replaced in 1944”
His blatant refusal to cooperate with Portal and his reluctance to change from area to precision bombing, (something that RAF Bomber Command was capable of doing and well) his blinkered obsession with the area bombing German cities, and his stubbornness to attack in numbers oil and transportation targets and other “panacea” targets.Should he have been replaced, and if so by who, Bennett, Cochrane, Rice ???
Over to you. 😮
Shortsbro I think your caricature of Harris is an over simplification of the facts and if it were entirely true it would be hard to see why Portal did not replace him. It would also reflect poorly on Portal for the fact that he did not. I think you need to understand the politics of the time, and how that Harris was possibly used by Churchill and how this relationship with Churchill may have given him the confidence to do things that would have otherwise needed higher authorisation or broader agreement. This relationship may also have inhibited Portal in his relationship and direction of Harris. Harris may have been determined and dogmatic, but I am certain that if He had not had the confidence of his Group commanders and headquarters staff Bomber Command would not have been as effective as it was. They weren’t all wrong!!!
Changing the Leader would not have lead to an immediate change in tactics, as there would have been a long period of retraining. Remember that 5 Group under Cochrane was operating as an independent command in the last year of the war with its own path-finder force, its own target selection and building on some of the Tactics that had been pioneered by 617 squadron. So I think the change of leader was not an option for change of tactics as they were changing anyway.
Another point to remember is that Britain needed to retain influence with the US and Russia and in the Politics of War a strong Bomber Command was an important tool, and sacking the leader would not have sent the correct message to the US or the Russians.
And it’s often portrayed that Bomber Command did not attack transport targets, oil plants or any of the Panacea targets. The fact is that they did, and often with a far greater weight and accuracy than the 8th Air Force. When the eighth flew in cloud they were no more effective than flying at night and scattered bombs in all directions. 100 group confused and bamboozled the Germans every night, as well as intruding night fighter stations. 8 group kept the residents of Germany awake every night, many intricate and complicated operations were flown that were more than a group of bombers taking off, flying to a city and dropping bombs aimlessly into the centre.
Hopefully some food for thought.
facts=-===============
Wow, I never knew that.
Did they swap crews between trips? Or was it the same crew doing both trips on the same night? You’d get through a tour pretty quick if that was the case.
As far as I know it would only be considered with new crews. Not sure of the exact numbers, but a squadron would have a compliment of 20 aircraft, of which 12 to 15 would fly any assigned raid. Later in the war some squadrons had a compliment of 30 aircraft. With 30 aircraft there would be 45 to 50 crews. So if a series of raids were being planned, some raids later in the night would be assigned to returning aircraft and new crews. Serviceability was always an issue so it did not happen every night.
The sneaky thing about the Mosquito was, that not only could it go to Berlin and back with a 4,000lb bomb, it could, and this is the clincher, do it so fast that it could do 2 trips in the same time as a heavy took to do one. On some winter nights up to 60% of 8 group’s bomber Mosquito’s would do 2 trips
Since someone brought it up…did the Germans fall for the ruse about the possibility of using B-29s in Europe?
Think TA152 and BV155 and I think you have your answer.
The First B29 to reach England was in fact one of the 14 YB29’s and it flew to England, partly as an eleventh hour test of a long range over water flight, and partly to fool the Japanese rather than the Germans. The Germans were already thinking B29 but the Japanese were wondering where the B29 would be deployed, and were aware of the long runways in and around Calcutta. So an elaborate plan was hatched with leaks to give the impression that the B29 had not measured up and would be used as an armed transport for Hump flights. The YB29 reached India on the 6th of April after spending 2 weeks in England.
I believe that only the first few Mosquito bombers with the short nacelles were finished in the Dark Green Dark Earth sky scheme. These aircraft were called B MkIV series 1. I haven’t got my references with me but not too many were produced before production shifted to the long nacelle version B MkIV series 2. As far as I can ascertain these aircraft were all finished in the day-fighter scheme, including sky spinners and sky fuselage band. These original machines were allocated to 2 Group Bomber Command as day Bombers.
2 Group was subsequently transferred to Fighter Command but the Mosquito Bomber squadrons transferred to 8 Group and started to fly at night. The sky bands and spinners had by this time stopped being applied to the Bombers, but they remained in the day fighter scheme with some units applying black under surfaces.
2 Group then re-equipped its Ventura squadrons with B MkVI’s to replace the lost day bombers squadrons and the original aircraft were again finished in the day fighter scheme, including the sky bits. For some reason I can’t recall this attracted adverse comment from the Aussies and Kiwis from the first two squadrons to re-equip and all subsequent MkVI’s for 2 Group were left in their factory finish Night fighter scheme. When asking about a particular aircraft it important to find a photo to be sure what scheme was used.
OK came across some additional info on this mystery. The asymmetric compression ratio’s only applied to the DB 605 and 603 as far as I can ascertain and not to the earlier 601. And as I explained above was as a result of passing oil into the cylinders from the lubrication system. Daimler Benz lubrication systems were perhaps not up to date when compared to other contemporary high powered aero engines. In particular the way the oil was feed into the mains resulted in it being forced against the centrifugal force of the rotating crankshaft. As a consequence more oil (at a higher pressure) than necessary to lubricate the mains was pumped to ensure that the big-ends were properly lubricated. This resulted in excess leakage (more than necessary for lubrication of the piston and small end, and any cooling requirements) from the bearings on to the cylinder walls and into the combustion chamber. Additionally DB used needle roller big-ends that leaked more oil than plain bearings. Due to the rotational forces more oil was thrown to one side of the engine than the other, hence the asymmetry.
Altering the compression ration to give greater detonation tolerance to the engine seemed to be a rather crude attempt to solve a major problem with the engines. Junkers did not have the same issues with the Jumo211 and 213, but they did a major update to the 211 to create the 213 with an up to date lube system with other mods that allowed the 213 far higher rotational speeds, way beyond what the 605 could survive at.
There is evidence to suggest that DB wanted to build the engines upright but were forbidden by the German Air Ministry. Interruption to production and all that rubbish I presume. And if I remember correctly aeration of the oil was another issue the 605 suffered from and is possibly implicated in the loss of some important German aces when the 109G was first introduced. And if I recall one of the current 605’s in Germany suffered a failed connecting rod a couple of years back.. Perhaps related to these issues?
Lastly I think interesting to note that the direct injection fuel system that allowed the use of lower grades of fuel had its advantages negated by a poor lubricating system, and with none of the considerable charge-cooling available by the use of an injection carburettor the DB engines were at a distinct disadvantage when compared to the Merlin and Griffon, not to mention the R2800 and Sabre. 🙂 🙂 🙂
I seem to recall that there is a good one on airliners.net
The above link that referrers to the differing lengths of the air intakes, is possibly only part of a very complicated answer. Detonation is the biggest problem to be overcome in any large high powered aero engine and the Germans had different problems to the British and Americans to overcome due to using direct fuel injection as opposed to a carburettor or an injection carburettor as later RR, P&W and Bristol engines amongst others used.
Basically mixture distribution into each cylinder combined with oil scavenging issues with the inverted engine resulted in the compression ration needing to be lower on one side of the engine than the other as oil would be drawn into some cylinders during operation of the engine. Small amounts of oil in the mixture can dramatically lower the engines resistance to detonation by lowering the effective octane rating (or performance rating) of the mixture entering some cylinders, and there is evidence to suggest that the DB engines had some issue with oil scavenging. Unfortunately I don’t have to hand the exact reason for it being one side or the other.
Additionally German engines used a higher compression ration with lower boost to achieve high power, as compared with RR for example, which used a relatively low 6 to 1 ration and high boost pressure to achieve the same result. This I believe was a contributing factor in making the DB engines sensitive.
This is off the top of my head from memory and I would need to do some digging to get the full explanation out.
To be honest I’m not an expert on Bomber Command / 8th Air Force tactics, but is it possible that the reason why Dresden was bombed was to prove that low level incendiary bombing of “combustible” targets was a viable alternative to high altitude bombing missions over Japan. I understand that several high ranking US staff members transferred to the Pacific from the 8th around the time of the bombing of Dresden. Or was Dresden bombed because it was a German city and therefore a target – one of many.
I don’t want to go into the ethics of bombing or the bombing of ethics, it just good to know why.
Dresden was bombed at the request of the Russians to help their army in the east that was very close to Dresden but bogged down. With bad weather in the west of Germany and the stalled counter offensive in the Ardens the army had started to transfer large numbers troops to the east and the Russians were taking casualties at a staggering rate. Stalin wanted the Western Allies to do more to help and requested various choke points to be destroyed. Dresden was just one of many of these places. It should have been bombed in January but the weather was very poor.
In fact most of the raids during this period had poor to middling results despite the tonnage dropped due to the poor weather. 13th Feb was no different. Except that incredibly on this night a localised hole appeared in the cloud and perfect visual conditions prevailed. And as all the flak had been removed to Berlin or the Russian front there was no opposition. A case of impossible to miss, with no early “bombs away”, or creep-back occurring.
As for being combustible Dresden was again in no way any different to all the other industrial cities, with one possible exception. The Nazis never allowed news of how other cities were coping with the air-raids to be shared, so the residents of Dresden had no experience or help of what to do once the bombs stopped dropping. They in fact stayed in their cellars, (where they suffocated) as there were no air raid shelters for the public, and they did not come out and help fight the many small fires that had started, or evacuate the area if the fires had taken hold.
Consequently etc etc etc
Dresden was not choked with refugees to the extent that has often been quoted, but that was one of the objectives to have the city choked up to help prevent the easy movement of troops and thereby help the Russians.
There was no conspiracy to terror bomb, or burn, or annihilate or any other theory. In fact the outstanding feature of the raid was that there were no C**k ups by the RAF this night. (C**k ups being an integral part of all warfare) I hope this helps a little. The 8th Airforce bombed Dresden the following day, on a day when they ranged far and wide over Germany. Perhaps as little as 15% of their force was directed at Dresden this day. The Politics of this raid is a fascinating subject, but some what complicated to explain quickly. I think that everyone was taken aback by the firestorm, but even then as a proportion of the total population the casulties in Dresden were not as high as in many other raids.
Sorry mate, can’t tell you. I know they’ve resurected this trick recently – I thought I’d seen it somewhere before. This show had a really good variety of old, new, and novelty. You certainly couldn’t get Concorde flying through any more. Was it this show where she was escorted by a couple of Spits? The old memory fails once again…
Due to a lack of time and space I still have to scan about 99% of my Slides, but I have this picture of Concorde in the same folder as the Mossie Blenheim and Gannet so I’m thinking it was the same show. 😀 😀
Gannet again
He’s one of the Gannet I managed to get.
I was there as well, in fact I must be just out of shot by the fence in one of the photos 😀 .
I seem to remember the commentator saying that some part or other had gone u/s and someone from PPS had flown back to Booker to get a replacement. But they unfortuately didnt get it airworthy before the end of the day’s display. 🙁I also remember that day for a scintillating 74 Sqn. F-4J display. 😀
I think that person rushing around for the part may be a forum member 😀 😀 😀
Seafury Fan
Was that Brendan O’Brian landing on the truck?
I always thought that act looked a bit dodgy but I loved it.
Is that a cub?
Anyone?
Andy
I seem to recall it was. Rather him than me
it makes my blood boil simply because it is one of the most terrible waste of craftmanship on earth: an airworthy FW190 D kept grounded!! I’d go there, slap the owner, jump in the cockpit and yell “Kontakt!!” 😀 😉
Cheers
arts could be found
IIRC there is a critical part missing from the engines computer control and this means that it will never fly with a Jumo unless the missing parts could be found 🙁 🙁
I was hoping to see 2 mossie’s and a Blenheim in the air that day. I think a week or so later we were done to just one Mossie.
