Oddly in the 8th AF records, none of those raids you cite are listed as ‘city targets.’
That's the point, the USAAF didn't often admit to area bombing.
There's no doubt they did, though. From The Combined Bomber Offensive, April Through December 1943, USAF Historical Study 119:
Most of the operations performed by the United Kingdom-based US strategic bombers are best classified as area raids of industrial towns.
From The Army Air Forces in WW2 by Craven and Cate:
There had, indeed, been a tendency on
the part of American air planners in the theater during early fall to
look upon the forthcoming radar-bombing campaign as a highly de-
sirable, if temporary, shift from pinpoint bombing of specific factories
to the British technique of area devastation in districts of industrial
concentration. Like the work done by RAF Bomber Command, such a
project would supplement the precision objectives of the POINT-
BLANK plan. Not only would property, and much of it of immediate
value to the war machine, be destroyed but the constant clearance and
reconstruction would have to be done by manpower taken directly or
indirectly from the war effort. Aside from its effect on civilian morale,
such bombing would constitute a direct attack on manpower, which
was naturally (though exaggeratedly) considered a critical factor in
the German war economy.
The reality is that (as with Bonn above) if you are carrying a load of ordnance over Germany in broad daylight it is ‘better’ to use it ‘somewhere.
That is area bombing. If you tell your crews that if they can't find the aircraft factory, unload over the nearest town, that's authorised, deliberate, area bombing.
As to the contention that they were using ‘area bombing techniques’ I really must continue to disagree. The 8th chose specific military targets as their primary targets
Not always. They frequently sent out bombers with a primary target as the centre of a German city. That declined in 1944, but the euphemism "marshalling yards" was used instead. But if marshalling yards were really the target, why use incendiaries?
On 22 February 1945 the USAAF carried out Operation Clarion, a series of attacks on rail transport in Germany. 35 marshalling yards were attacked. It was a deliberate attack on rail transport, not a cover for area bombing. Attacks were carried out at low level for maximum accuracy. 3,121 tons of HE were dropped, 1.3 tons of incendiaries. I make that 0.04%
But in their typical attacks on "marshalling yards", the 8th dropped from high level, using radar, and with a high proportion of incendiaries. Those are tactics designed to damage the city, not the marshalling yard.
As to incendiaries - even if they aren’t good at breaking rails, they are good at setting rolling stock and station facilities on fire. Again, I don’t think this proves a change of policy
I don't think they are very good at setting rolling stock on fire. Bomber Command must have thought the same, because they didn't use incendiaries to any great extent in attacks on marshalling yards. Neither did the 15th AF. And even the 8th, when on deliberate operations like Clarion, didn't use many incendiaries.
They didn't use many incendiaries over France, either. In attacks on marshalling yards in France the 8th used just 0.67% incendiaries. In Belgium, the Netherlands and Luxembourg 1% incendiaries. In Germany, 18.6%.
Davis, Carl A. Spaatz and the air war in Europe:
A further look at Eighth Air Force operations has revealed two egregious
examples of the gap between bombing practice and stated bombing policy: the
target categories “city areas” and “marshaling yards.” The two most cited Eighth
Air Force statistical summaries that cover the entire war do not list a target cate-
gory “city areas” or “towns and cities.” Both summaries were prepared from
the same set of data within a month of the end of the war in Europe.
Monthly statistical summaries of the Eighth’s operations prepared during the
war, almost contemporaneously with the events they recorded, tell a different
story. The Eighth Air Force Monthly Statistical Summary of Operations, gener-
ated at the end of each month from May 1944 to April 1945, listed a “city areas”
target category. For calendar year 1944, the summary reported that the Eighth
dropped 43,611 tons on “city areas.” Nor did these reports make any bones
about their targets. The report for the May 8, 1944, Berlin raid baldly states,
“Berlin city area attacked. Bombing raid done through 10/10 undercast on PFF
markers. Believed that the center of Berlin was well hit.” After reaching a
high of 9,886 tons (41 percent incendiaries) in July 1944, when the Eighth con-
ducted a series of H2X raids on Munich, the monthly “city area” totals steadily
declined to 383 tons in December.
A summary in a working paper from a USSTAF file, “Review of Bombing
Results,” shows a similar dichotomy according to time period. From January
1944 through January 1945, the Eighth dropped 45,036 tons on “towns and
cities.” From February 1945 through the end of the war, this summary
showed not a single ton of bombs falling on a city area. Unless the Eighth had
developed a perfect technique for bombing through overcast, such a result was
simply impossible. Obviously, the word had come down to deemphasize reports
on civilian damage. For instance, when Anderson cabled Arnold about USSTAF’s
press policy on the Dresden controversy in February 1945, he noted, “Public rela-
tions officers have been advised to take exceptional care that the military nature
of targets attacked in the future be specified and emphasized in all cases. As in
the past the statement that an attack was made on such and such a city will be
avoided; specific targets will be described.”
The U.S. Strategic Bombing Survey, although not explicitly listing a target
category such as cities or towns, had an interesting definition of “industrial
areas.” The survey placed three types of targets in “industrial areas”: (1) cities,
towns, and urban areas; (2) public utilities (electric, gas, water, and telephone
companies); and (3) government buildings. Given that definition the survey even
managed to describe RAF area raids as strikes against “industrial targets.”l79
The target category “marshaling yards” received more of the Eighth’s bomb
tonnage than any other, somewhere between 175,000 and 200,000 tons of bombs.180
At least 25 percent of all the Eighth Air Force bombs dropped over Europe fell on
“marshaling yards.” One-third of the American incendiary bombs dropped over
Germany fell on the same system. As a matter of directive and policy for most
of the period between September 1944 and April 1945, the same period in which
the Eighth delivered 90 percent of the total tonnage dropped on the system, mar-
shaling yards had the highest nonvisual bombing priority. During that period the
Eighth Air Force dropped 168,038 tons of bombs, 70 percent (117,816 tons)
blind and 30 percent (50,222 tons) visually.181 Postwar research showed that
only 2 percent of bombs dropped by nonvisual means landed within 1,000 feet
of their aiming points.182 Rail yards as such, however, were poor targets for
incendiaries. If the fire bombs landed directly on or near rail cars, they destroyed
or damaged them; otherwise, they could do little harm to the heavy equipment or
trackage. The Eighth realized this. Of the 9,042 tons of bombs dropped on
French rail yards, mostly during the pre-OVERLORD transportation bombing
phase, when the Americans took scrupulous care to avoid French civilian casual-
ties, 90 percent were visually sighted and only 33 tons were incendiaries.183
Even over Germany itself, during Operation CLARION, when the Eighth bombed
dozens of small yards and junctions in lesser German towns, it dropped, over a
two-day period of visual conditions, 7,164 tons of bombs in all, but less than 3
tons of fire bombs.
In contrast, using H2X, the Eighth pummeled marshaling yards and rail sta-
tions in large German cities with high percentages of incendiary bombs. For
example, rail targets in at least four major cities garnered the following percent-
ages of fire bombs out of all bombs dropped on them: Cologne, 27 percent;
Nuremberg, 30 percent; Berlin, 37 percent; and Munich, 41 percent.
“Marshaling yards” undoubtedly served as a euphemism for city areas. Because
the yards themselves were not good targets for incendiaries, the prime purpose
in employing such weapons was to take advantage of the known inaccuracy of
H2X bombing in order to maximize the destruction of warehouses, commercial
buildings, and residences in the general vicinity of the target. Large numbers of
planes scattering their bombs around their mostly unseen and unverifiable aim-
ing points surely would cause great collateral damage to any soft structures
located nearby.
I know I am splitting hairs! However, I still see a difference between pursuing a policy which says try to hit a specific military target and if not, then hit an industrial area – or even an area and that which says hit the area! And I know it is legalistic, but I don’t think that this shows intent.
I can't see how you can say a deliberate order to bomb a city, even if as a secondary target, isn't intent. If you issue orders to kill person A, if he can't be found kill person B, good luck in court arguing you didn't intend to kill person B.
I am clearly going to have to get hold of a copy of that article
