SOCIPIC ADVISE TO DM AMMa
No 2 Operational Rlesearch Section took part in the oaqvai~n with
21 srmiy Group from D day tothe German surrender. Wlhen the7v returned to
this Country on 20 July 194g5, 1 directed them to collect and arrange in a
yerimanent fain, the records of their work.
This involved mainly collating
Sseries of written reports, but it was &A3~o a matter of great interest to
:~and zV department to consider to what exxcent ral progress had been a
in this entirely now scientific subject, that of attempting to aLpply our"MQ~ hods to the study of now aspects of warfare.
I thcrafore asked for a history of the work or the section, and
for anty ideas on the methodology of the rcsosrch.
This was writt-nin t~e
first instance, entirely for internal use in my dcparbnmnt, but on reading
it I fclt that it provided a background for the riort3, gave a cohorboe t6
the work is a. ,ihAwe that vim vory valuzable, and mer.tod a widor circulation.I hav4 therefore decided to add -this account as an introductiofl
TO the reports.
I have not ,edited it in any way, and it remains as it was
written - a record of the vigs and reactions of a group of young soldierscientists, intended for the eyes of other scientists.
In giving it a widur circulation I rmast emphasise that in no sense
is it an official document, and this is tndood obvious from its informal
style, but I hope it will help to convey the atmsphere, in which. the work,
describcd in the reports, was carried out.
I feel that this account of the work of No. 2 Operational Research
S~.ction in North West Europe goes so=e considerable way to answering the
-laostions 'What is Operational Research?*.
W~hat does it do? How does
it do it?m 1koh of what is recorded here is pioneer work, in the sense*
that nothing quite like it had previously been attempted. I believe that
nobody, reading these reports, can tai4. to agree that they represent a great
stride forward in the objective study!of war, and the factual recording of
what takes place in battle.

sur'prise that research found such wide applications to the tedudn~ely
&Vficult but fwdamentaly amnble problems of Radar, hti-aircrsft
cr 1-tapntation, to name only a few. These problems offered gpeat
possibilities to the wonl-established mothods of the physical sciences.

Ieports on Heavy Bombing
Studying these Heavy Bombing attacks was a laborious and depressing
affair, and at the time we prayeod that we should never have to do any
mor of it.
The dust and the appalling quantities of traffic, which
still seeed to outdo the heart of London, mae travelling to and fro an
Having arrived at the front, we had to probe sbabt.
in the desolation of one French village after another, ofton uncoeortably
loso to mortaring, shelling, and the front line, and search out fr-m
thir hiding plaes units who had taken part in the battle. When we
roturnerd there wre air photographs to be pore-l over, and a thuatnd vj
one fragments of informawtion to be assumb2od. It has been suggested
that once froshkgroun has been broken by the Operational Roseir6h
Section, and a now method evolved, the work should then be carried on by
others. Certainly in the case of those operations, much an arranipmont
us to do far more, and more important perhaps, Liven
us time an oneorg to develop new ideas.
Satiated as we now -felt by field wok, we sat down to think, and
to write a report (wmbor 1%) on Heavy bombing in Support of the ,,Wwhich, thought it never went farther than 21 Army Group HeAquarters,
did much to clear our ideas. It had been intendo as a simplo guide,
but was vetoed as being too contentious and outspoken. Lastly, as an
application of what we had laid down in our report on Heavy B3bingo we.
started one evening and worked furiously into the night, making out a
plan based on bombing river lines, for blocking the German retreat fromn
the W isn trap, then fast assuming the shape of a pocket. The plan
* was nover adopted for various reasons, but some weeks Inter we had the
molancholy satisfaction of showing how many Gormans escaped from the
pocket and proving that a very belated attempt to block on river lines
had been quite inadequate. It ma ouw belief at the time that had the
4ir Forces been employed differently far fewer Germans would have got
back acroes the Seine, &A the course of the war might have been gr tly
changod. But it remoins only a speculation, where each must Jude for
Iil. Rtamning veicles from the Pockt
to the olna.
fw days after our attempts to fram
a plan kar blocking the
retreat, fthe entire Soetion was ordered down to the "Podkot* to
find out what the Ur Forcos had boon able to do to the Goromns in tun
samo retreat. That day en advance party wont down to find aowhen to
live, and the next day every officer, and all but one or two Other Ranks,
went down to Flors, a imll town placed fairly centrally in what had boon
the eastern ond of the pocket.
For the first time the notion was fully
mobile and fully independent, and it was an enjoyable sensation. The
countryside, te libortion spirit of the French, and the absence of

Operation Orders and plans& Is a rocult of anl this study, artillery
|rograins grow in elaboratiobn and efficiency. Hundreds of ms could
fired on a perfectly timed sohodule or directed at a momnt' a notice
on to a particular target. But in the struggle to got the bost
artillery support, the armies had onoontrated on the means of bringing
down the high explosive rather than on the moans of overpowering the
enemy with that high explosive. In consequence, though the mohani
of laying a concntration were fully understood, there was nothing to
indlicate whether the concentrations of Operation A or of Operation 2
wore the mao effoctive, ant there was practically no infowation on,
rat the stupendous qiantities of artillery aetuaifly did. Sm favowm
qiek heavy concentrations, ethers preferred prolongod light ones-, an
e thing however all wire agreed, that the more shelas w=r fired offL
the roatoer was the chkno of success. In consequence barrages got - *
bigger and big1gr, Wns wore out faster ant more transport was moodod,
for carrying amunition. rhereas in the last wtar battles tended to wait
on the accumation of aitfficient expendable manpower, now they tended
to vait on the building up of vat stocks of ammunition. -Those than
r norlying reasons for attempting to invostioate fire support.,
Our mans of investigation included these of the military Observr 7watching the battle, discussing with units, and studying the orders aid
plans - but they vent further; to these throe w added the interrogation of prisoners, the detailed examination of the batt2fial and th
study of records such as medical casualty returns, aonunit,n ozponditire shoots and counter-.'eattory lops. If an enemy positiona held out
