If Germany had committed these crimes against another nation, the world would still be talking about
it with justified outrage to this day. But since the perpetrator was a more
politically correct empire, let's blame the victim instead: read on!
It seemed to the Foreign Office and to those who will be responsible for the future
education of British naval officers that it was really important that a history of the
blockade should be compiled, and it was accordingly proposed to the committee
controlling the official histories of the great war that this work should be
undertaken; the committee accepted the suggestion, and Mr. A. C.
Bell, of the Historical Section, Committee of Imperial Defence, was entrusted
with its compilation. The Library of the Foreign Office, which is responsible for
all historical work that is undertaken by that department, and the Historical
Section of the Committee of Imperial Defence, which is responsible for producing
all the official histories of the war, became conjointly responsible for putting
together, and making available, the material upon which this particular history
was founded, and for exercising some general supervision over its production; as
this conjoint responsibility has throughout been a cordial
co-operation, it has never been necessary to settle what share of responsibility was
borne by the Library or the Historical Section. It soon became apparent that the
work would not be suitable for publication, but (like the official History of
Military Operations in Persia) should be printed and kept solely for official
uses.
The history is principally based on official material contained in the archives of
the departments concerned with the direction of the
blockade - first and foremost the Foreign Office, and then, though in a
noticeably less degree, the Admiralty. It was not practicable to consult the
archives of the Board of Trade owing to the time limits imposed on the historian,
who was obliged to content himself with the Board of Trade letters which appear
in the Foreign Office files. The typescript was submitted to the Admiralty, who
made a number of valuable suggestions; the Board of Trade also received a copy
of the typescript, but they declined to take any responsibility for the history. In as
much, however, as the general direction of the various operations (apart of course
from the naval side), which are described as the blockade, was centred in the
Foreign Office, where the Minister of Blockade, when appointed, was established,
it is only natural that the bulk of the material on which the narrative is based is to
be found in the archives of that office, which include those of the special
departments created for the purpose of dealing with particular aspects of the
blockade, such as the Contraband Committee, the War Trade Statistical
Department, the Restriction of Enemy Supplies Department, the War Trade
Intelligence Department and the Foreign Trade Department. It may therefore be
desirable to state that, while the present work is an official history written from
official archives, in this case mainly from those of the Foreign Office, it has never
been the practice of that department to allow current policy to influence any
historical research which has been undertaken at Foreign Office instance. At the
same time, the official historian is under an obligation, in view of the nature of the
material which he has been authorised to use, to consult with the officials of the
department and to ascertain their opinions on the operations which he describes;
and in the present case it was naturally desirable that as much assistance as
possible should be obtained from officers who had actually taken part in the
conduct of the blockade. The long list of Foreign Office officials, retired and
active, who have assisted the historian shows that this has been done with regard
to the present work.
It is also desired to acknowledge, with thanks, the help of Mr. C. V.
Owen of the Historical Section of the Committee of Imperial Defence, who
compiled the statistical tables, and as Colonel E. Y. Daniel, C.B.E., the
Secretary to the Historical Section considers the help that he has given to official
historians for twenty years past to be a mere matter of duty which calls for no
remark, this places everyone who benefits from his assistance under a very
particular obligation to acknowledge it duly.
The historian has found it necessary on certain occasions to express his own
views: these represent his personal opinion and are not necessarily endorsed by
the Foreign Office or any other Department of His Majesty's Government.
Finally, the word blockade in the title of the book should be regarded as if it were
placed in inverted commas: for the expression, though conveniently employed as a
general description of the measures taken by this country to deal with enemy
commerce during the great war, is technically inaccurate, as a legal blockade of
the central powers, in the technical sense given to the word in international law,
was never declared, and the powers taken by Order in Council to deal with the
trade of the central powers generally, and Germany in particular, were justified as
reprisals for their infractions of international law.
