Bomber Harris, not a happy man (3)

As I mentioned in my two previous blog posts, Roy Irons’ book “The Relentless Offensive: War and Bomber Command” is one of the most informative I have ever read about the RAF’s bombing offensive over Germany, and the man from Southern Rhodesia in charge of it, Arthur Harris:

In the early years of the conflict, of course, the biggest problem faced by the RAF was that most fundamental of questions, namely whether the somewhat second rate aircraft of Bomber Command were actually hitting their targets in Germany:

An early attempt to find out the answer to that rather basic question was the Butt report, which examined night bombing by the RAF in as much detail as possible, and produced its rather disappointing conclusion in early August 1941.

The Butt Report discovered, for example, that most bombs dropped at night did not fall within five miles of their target. At the same time, though, the huge losses of aircraft and aircrew during daylight raids in 1939-1940 meant that the RAF could not possibly switch to that approach as a method of bombing the enemy with any claim to accuracy.

The only solution, therefore, was to continue with bombing at night, but, instead of worrying about civilian casualties, to pursue the Luftwaffe’s own tactic of bombing a whole area, rather than a specific target. Churchill and his war cabinet immediately ordered this change in policy from specific targets such as a factory or a railway junction, to the general bombing of an entire part of a city or town.

Area bombing, of course, could be extremely effective. It flattened the factories of the Third Reich and it destroyed the homes of the workers who worked there:

A new leader was appointed at Bomber Command to implement Churchill’s policy and to develop the tactics and technology to carry out the task more effectively. That man was Sir Arthur Harris, commonly known as “Bomber” Harris by the press and often within the RAF as “Butcher”. Harris was the most forthright of men and he did not suffer fools gladly:

Harris’ brief was to kill Germans. Anybody or anything which impaired the RAF’s ability to do this, he would subject to a severe tongue lashing. Even his ordinary opinions were extremely forthright, although there is little to fault in his thoughts about the conflict and what we had to do:

“War. The only thing that matters is that you win. You bloody well win !”

Such directness was why Harris ended up so hated by so many of his upper class superiors. He was, though, adored by the men under him, the “Old Lags” as he called them. Harris committed the cardinal sin of telling a large number of people, particularly those who outranked him, just how useless they were.

We have already looked at the problem of dropping bombs by night on, for example, the Gelsenkirchen tank factory and destroying it completely, but causing no damage whatsoever to the Gelsenkirchen Tea and Coffee shop next door.

That dilly of a pickle was solved, eventually, not just by the introduction of area bombing, but by improvements in the RAF’s technology and by training navigators until they knew what they were doing:

At the same time, another major problem was that enormous numbers of bombers were being shot down, either by flak or by nightfighters. This in turn, deprived Bomber Command not only of an expensive aircraft, but of a trained pilot, a trained navigator, a trained bomb aimer and any number of trained gunners and so on:

 

Many of these problems came from the fact that all British bombers were defending themselves with 0·303 guns, that is to say, guns of exactly the same calibre as an ordinary soldier’s rifle. In the 1920s, a lecturer at the RAF Staff College showed perhaps just how confused thinking was on this subject. Try as I might, I can make no sense of what he said:

“The aircraft gun is not likely to be required to penetrate armour and a couple of 0·5 inch bullets in a pilot will incapacitate him as much as the fragment of a one and a half pound shell. On the other hand a 0·303 bullet has but little effect on any aeroplane.”

Strange arguments, but whatever point is being made here, it is clear that the enemy pilot was being viewed as the target of the bomber’s defensive fire rather than his aircraft. All that was needed to hurt him was a rifle bullet, so the 0·303 gun was chosen. Here are the three turrets of a Lancaster:

The official explanation for keeping the 0·303 guns was that eight 0·5 cannons, firing deadly explosive shells, were too heavy to be carried and would compromise the Lancaster’s bombload. Furthermore, the weight of the stored ammunition for the cannons would always affect the centre of gravity of the aircraft. That latter point is ridiculous, of course, because, in his design of any future bomber, the designer would automatically make due allowance for the weight of the ammunition, including any changes in that weight as the ammunition was used.

Not connected with this book by Roy Irons are the almost irresistible stories of aircrew using their initiative to protect themselves. Somewhere I have read of turrets being taken from the B-24 Liberator and used as rear turrets on Lancasters. Somewhere else I am reasonably sure that I have heard of unofficial swaps between the turrets from Lancasters and the turrets from Vickers Wellingtons.

Whatever the truth of this, The  RAF did order 600 Rose turrets in June 1944. They were equipped with the two of the standard American defensive weapons used in the turrets of the B-17 Flying Fortress and the B-24 Liberator:

The weapon in question was the American light-barrel Browning ·50-calibre AN/M2 heavy machine gun. Four hundred turrets were completed by the end of the war although only a mere one hundred and eighty  were fitted. Typical of Harris’ remarks was his statement that:

“this turret was the only improvement made to the defensive armament of the RAF’s heavy bombers after 1942, and those responsible for turret design and production have displayed an extraordinary disregard for Bomber Command’s requirements”.

Bomber Harris, not a happy man (1)

I hope that I don’t produce book reviews too frequently, and I certainly always limit myself to books that I have read and that I know I have enjoyed. In such a category is the 288 page book, “The Relentless Offensive”, War and Bomber Command 1939-1945″. The book is priced at £21 for a new hardback but there are plenty of reduced price copies as low as £4 or £5 including delivery. Here’s the cover:

Amazon, the seller of the cheaper used examples, says that the book is ” a fresh analysis of Bomber Command, its tactics and technology.” This is correct but there is more to the book than that, with, for example, in-depth discussions of high-explosive bombs and explanations as to why apparently identical bombs differed so much in effectiveness. The defensive armament used by Bomber Command aircraft is examined and explanations offered to explain its ineffectiveness:

Perhaps most important of all, why was Bomber Command’s navigation so frequently so very, very poor? Failures in this area would eventually lead to the conclusions of the Butt Report, which stated on August 8th 1941, after two years of war,  that:

“only about one-third of aircraft claiming to reach their target actually reached it.”

Here is the Butt Report, looking a little dog-eared today :

Of that successful third who flew through the night, and reached the target, when it came to dropping bombs, ”only one in three of them got within five miles”. In other words, a mere one ninth, 11%, of the aircraft claiming to have flown over the target, did, in actual fact, get anywhere near to dropping their bombs accurately on said target. On occasion the wrong town or city was bombed. At least one Old Nottinghamian did this. They returned triumphantly from their raid only to find out that they had not bombed Genoa but a seaport some thirty five miles away called Savona. Sometimes, the German town received virtually no bombs at all and the inhabitants did not realise that they were the target of an RAF raid.

In similar fashion, the RAF appeared on occasion to be targeting what the Germans on the ground thought was a bizarre target, such as a cheese factory or an ice cream works. Still, at least the RAF did not bomb Switzerland quite as frequently as the Americans did (“Gee, the target was lit up like a Christmas tree”) or as the Germans bombed the Irish Republic (Dublin on several occasions. and also Blackrock Island off the coast of County Mayo, damaging the several lantern panes and the roof of the lighthouse.) Here’s the lighthouse, a difficult building to find and to identify, especially in broad daylight:

Clearly, the problems of reaching a target at night and bombing that target when you couldn’t necessarily see it, had not been solved during the first two years of the war:

To make things even worse, Butt did not include at any point in his examination “those aircraft that did not bomb because of equipment failure, enemy action, weather or which failed to find the target”.

When, in 2003, modern researcher Hank Nelson carried out Butt’s calculations, taking into account this final category of the aircraft who did not drop their bombs for a variety of reasons, he discovered that only about 5%, one twentieth, of RAF bombers setting out from their bases in England bombed within five miles of the target. Other modern research, presumably nowadays making some use of German sources, has since then revealed that “49% of Bomber Command bombs dropped between May 1940 and May 1941 fell in open country”.

The places being bombed heavily, therefore, must have included all of the countryside behind this strategically important railway viaduct:

Such inaccuracy is one of the main areas examined by Roy Irons in his marvellously interesting book. Some of the reasons that 95% of Bomber Command aircraft might as well have stayed safe at home we will look at next time.
