INTRODUCTION
Preparations and Statistical Section, _gen eral papers
Second World War
Section F documents Cherwell's growing preoccupation with the inevitability of
war and the problem of air defence, and presents a general picture of his service to
Churchill during the Second World War.
Papers from the same period on more specific
topics are in Sections G (military and scientific) and H (economic).
In October 1939 Cherwell was asked by Churchill, then First Lord of the Admiralty,
to assemble a group of economists who would collect and co-ordinate Admiralty and
other statistics.
The group became known as the First Lord's Statistical Branch ('S'
Branch) and the first members (in order of recruitment) were G.D.A. (later Sir Donald)
MacDougall, H. Makower, G.L.S. Shackle, H.W. Robinson and D.G, Champernowne.
R.F. (later Sir Roy) Harrod joined the group on 1 January 1940;
other members included
D.M.B. Butt, E.J.S. Clarke, W.A.B. Hopkin, C.M. Kennedy, C.J. Martin, W.R.
Merton, J.R. Parkinson, F.R.P.
Vinter and T. Wilson.
The functions of 'S Branch' are described in F.41 as follows:
'l.
To compile and keep up to date the album of charts and diagrams
which the First Lord has circulated to the cabinet ...
To answer at short notice questions by the First Lord on any matter
involving statistics with which he may have to deal as a member of
the War Cabinet and other Committees.
To analyse statistics relating to the Navy and cognate matters
and present the results in diagrammatic form both for the information
of the First Lord and for his use in discussion,
in 1945,
When Churchill became Prime Minister in May 1940 he retained 'S Branch!
as an independent department outside the normal machinery of government, and it
became known as the Prime Minister's Statistical Section, or sometimes, after
Cherwell's appointment, as Paymaster General in December 1942, as the Office of
the Paymaster General,
It remained in existence until the change of government
To read all cabinet papers on economic matters and draw the
attention of the First Lord to points which he might wish to
take up.'

Preparations and Statistical Section, general papers
Second World War
Harrod (The Prof, p.221) relates that
Although the scope of the work and the number of staff grew in accordance with
the increased importance of the Statistical Section, its essential function remained the
collection and distillation of information.
Churchill wished Cherwell to range over the whole field of the war effort, excluding
only military operations and personal appointments and promotions.
Cherwell's interest was concentrated on military and scientific problems, and there
isa large corpus of material relating to the development, production and use of various
weapons and armaments.
But he also involved himself in a wide range of economic
topics including the efficient use of shipping tonnage, the production of food and raw
materials, manpower, negotiations with U.S.A. for military and economic aid and,
in the latter stages of the war, in the various problems relating to post-war reconstruction.

Statistics were assembled on all these topics from cabinet papers, departmental
minutes and reports, and correspondence with colleagues in government departments
and scientific and military establishments.

contained in Sections Gand H.)
In addition, Cherwell and his staff quantified and
criticised the available data and assumptions on a wide range of major issues.

example, the size of the German Air Force, the accuracy of British bombing and the
existence and scope of the German V-weapons have been widely discussed in the pub-

to Section G).

The quantity of material involved has prohibited any attempt at cross-

nevertheless, all the wartime papers are closely interrelated, and material in
this Section may sometimes amplify or complement (or even duplicate) material
elsewhere in the collection.

INTRODUCTION
The papers in Sections G and H document the daily activities of the Prime
Minister's Statistical Section during the Second World War.
The material is pre-
sented in two Sections for ease of reference but the distinction between Sections G
(military and scientific papers) and H (economic papers) is a rather artificial one,
and does not reflect the original ordering of the papers which could no longer be
reconstructed.
Similarly, the presentation of the material in Sections G and H
is the work of the present compilers although in places it draws on the previous
arrangement of the papers made in 1965 (see General Introduction).
The origins and function of the Statistical Section have already been out-
lined in the Introduction to Section F.
The material in Section G provides
some of the background to Cherwell's minutes to Churchill in the form of statistics,
correspondence, reports and summaries of cabinet and other papers.
It

and in other parts of the collection, especially F.88 - F.252.
Section D also contains some correspondence re wartime scientific
sented under the general headings listed at the head of the Section, but there is
inevitably some overlap between various groups of papers, both within this Section
work.

BRITISH AND GERMAN AIR FORCE STRENGTH
The following papers document the dispute between Cherwell, the Air Ministry
and the Ministry of Economic Warfare over estimates of the comparative’ strength of
the British and German Air Forces.
The course of the disagreement, which arose
in the summer of 1940, has been described in the published literature.
In December
1940 Churchill appointed Sir John Singleton to make an independent enquiry into
the available estimates, but although Singleton presented a report to Churchill in
January 1941, many of the differences still remained unresolved.
A second report
was prepared by Singleton in August 1941, and this essentially marks the end of the
dispute, although correspondence and papers on the subject continue until 1945.
A few papers on other aspects of air warfare are included at the end of the
Section as follows:

Bay Patrol, March~April 1943.
At the 21st meeting of the Committee on Anti-U~boat Warfare (see G.119),
@ paper was presented by Admiral Stark suggesting that if aircraft could be made
available they should carry out as soon as possible a concentrated patrol and hunting
of U-boats in their greatest areas of concentration, namely, an area of 200 miles
wide across the entrance to the Biscay bases.
A special meeting was held on 5 April 1943 at which the Ministry of Aircraft
Production was asked, in consultation with Departments, to prepare an agreed note
as to the rate of monthly sinkings in the Bay which it might be expected to achieve
with a given increase in air strength.
The following papers include several drafts of a telegram to be sent by Churchill
to President Roosevelt, asking for additional aircraft to increase the possible effective-
ness of the Bay Patrol.

WEAPONS, DEFENSIVE DEVICES, MILITARY ORGANISATION
AND STRATEGY
The following papers reflect Cherwell's considerable interest and involvement
in the contribution of science to the war effort.
His interest in weapons development
has sometimes been dismissed as a mere love of 'gadgetry', but this criticism under-
rates the value of the support he gave to numerous projects for research and develop-
ment, even if in some cases his enthusiasm was misguided and the project eventually
proved unsuccessful.
The material is arranged by subject and presented in alphabetical order.
A list of contents appears overleaf, but it must be stressed that it has not been
possible to provide cross-references to other material on the topics listed which
may appear elsewhere in Section G or in other parts of the collection (especially
Sections Dand F).
Particular mention should be made here of some of the more
substantial sets of papers such as those on Bombs and Bombing (G.117-G.209)
M.D.1 (G.246-G.306), U.P.s and Proximity Fuzes (G.376-G.409) and the German
V-Weapons (G.410-G.440).

U.P.'s (UNROTATED PROJECTILES) AND PROXIMITY
FUZES
;
1939-43
The summer of 1939 saw the
setting up of the Projectile
Development Establishment \ work on the development
of 'Unrotated Projectiles' (rockets).
The research was
directed by A.D. (later Sir Alwyn) Crow and a wide
variety of weapons was investigated.
In September-October 1939, at Cherwell's instigation,
research was being carried out by the Admiralty into the
possibility of filling anti-aircraft shells with small aerial
mines attached to a parachute by a long wire.
It was then
suggested that the mines might be packed with the parachute
and wire into a cylindrical container and attached as the head
of a U.P. and the resulting apparatus (known as a P.A.C.
weapon) was used as a defence against dive bombers from ships.
See also G. 550.
Another early investigation was into the possibility of
making some form of guidance system fora U.P.
project was called the 'Spaniel' (see G.385-G. 387).
This
See also D.136.
The following papers contain minutes, drafts, corres-
The early U.P. weapons used delayed action fuzes but
these were unsatisfactory for several reasons, so efforts were
made to design a fuze that would cause an explosion only
when an enemy aircraft was in range.
This was known as
a proximity or 'P.E.' fuze and it used a photoelectric cell
which would activate a detonator when the shadow of an
aircraft fell across it. | The design was not entirely satis-
factory as the fuze was apt to react to clouds and birds and
even to varying intensities of daylight.

INVENTIONS AND IDEAS
In the course of the war Cherwell received many ideas for offensive or defensive
weapons, devices, methods for improving various aspects of the war effort or conditions
of life.
Some of these he answered himself; many were passed to J. L. Tuck for
evaluation and thence sometimes to other departments for further investigation, giving
rise in some cases to a substantial exchange of views.
