The Defence of the Realm: The Authorized History of MI5 Paperback – January 1, 2009

4.4 4.4 out of 5 stars 724 ratings

An unprecedented publishing to mark the centenary of its foundation, the British Security Service, MI5, has for the first time opened its archives to an independent historian. The book reveals the precise role of the Security Service in twentieth-century British history, from its foundation by Captain Kell of the British Army in October 1909, through two world wars, up to and including its present roles in counterespionage and counterterrorism. The book describes how MI5 has been managed, what its relationship has been with government, where it has triumphed, and where it has failed. In all of this no restriction has been placed on the judgments made by the author."Defend the Realm "also adds significantly to our knowledge of many celebrated events and notorious individuals and definitively lays to rest a number of persistent myths.""Above all, it shows the place of this previously extremely secretive organization within the United Kingdom. Few books could make such an immediate and extraordinary increase to our understanding of British history over the past century.

    MI5, the British Security Service, was not even acknowledged until 1989, and has now reached the century mark with a massive, authorized biography. This truly compendious volume, commissioned by MI5, was compiled by the acclaimed intelligence writer and historian, Christopher Andrew.
    This is a history of the one hundred years beginning with the founding of MI5 in 1909 in response to the Edwardian spy mania, changing from a focus on counter-espionage and counter-subversion to one of counter-terrorism. It remains perhaps the most famous and effective clandestine agency in the world.
    The role of MI5 has changed over the century: while maintaining secrecy in order to effectively protect parliamentary democracy, it has been under increasing pressure to be as transparent as possible. Mr. Andrew, professor of modern history at Cambridge University, was chosen to delve into the secret history of MI5 and given unrestricted access to the 400,000 internal files of the service.
    No doubt, Mr. Andrew opened himself to criticism in that he has asked his readers to accept his analysis upon faith. Since the rest of us cannot independently verify his conclusions , we must put our trust in his integrity. Sometime in the future, other researchers may be given access to the files, and this has surely given pause to Mr. Andrew to accurately record his findings.
    The result is a wonderfully detailed look at the critical issues confronting the Security Service from the time of British imperialism, through the “Red Scare” and “Boche” period of pre- and post-WWI, the Second World War, the Cold War, the exposure of the Soviet infiltration of both MI5 and MI6, and up to the terrorism threats of the turn of the present century.
    Beginning with the card index of suspicious persons (over 200,000 names in 1917), the concerns of MI5 have been widespread; the 1920s and 30s were concerned with the threat of international communism; WWII brought fears of fascism in Europe and Asia. The Cold War ushered in Soviet skullduggery and the need to combat al-Quaida after 9/11.
    The thousand-plus pages of this book are brimming with details of the achievements—and failures of MI5. Was counter-intelligence specialist Peter Wright correct about infiltration of the services beyond that of the Cambridge Five? Was P.M. Harold Wilson correct in his belief that MI5 was surveiling him?
    Jews were prohibited from serving in MI5 until the late 1970s because of their perceived double loyalty to Britain and Israel. MI5 chief Guy Liddell testified before the Joint Intelligence Committee in 1949, stating that “n_____ coming here often went to the C[ommunist] P[arty]” and that “West African natives are wholly unfitted for self-rule.” MI5 conducted secret surveillance of the colonial delegations coming to London for post-WWII independence discussions. It must be admitted that the transition of power from the British Empire to independent states in Africa and Asia came off much more smoothly than the same transitions by the rest of the European countries.
    The notable achievements of the Security Service include the Double-Cross System of WWII; the complete list of successes is limited by the need to maintain secrecy, a problem of all clandestine agencies; the measure of their success is judged by the things that do not happen.
    Defend the Realm is not a flawless book. In any security service, it is difficult—perhaps impossible—to separate fact from fiction. With its eccentric mix of professional soldiers, amateur spies, and false identities, it is to Mr. Andrew’s credit that he has achieved so much.
    Mr. Andrew is an historian of high repute. His studies of Soviet intelligence in collaboration with two defectors and ex-KGB officers, Oleg Gordievsky and Vasili Mitrokhin, are monumental. His books include KGB: The Inside Story (1990), The Sword and the Shield: The Mitrokhin Archive and the Secret History of the KGB (1999), and The Word Was Going Our Way: The KGB and the Battle for the Third World (2005).
    As for criticism that his appointment as official historian for MI5 (he was too close to the Security Service to be impartial), his response as quoted in The Guardian was, “Posterity and postgraduates are breathing down my neck. I tell my PhD students: I know you can only get on in the profession by assaulting teachers. You are not going to make a reputation by saying, ‘Look, Professor Andrew was right all along the line.’” As MI5’s files are eventually opened to other researchers (as they will no doubt be), Mr. Andrew’s work will be scrutinized. Any “white-washing” would be exposed and his work undermined.
    Defend the Realm is a most valuable and comprehensive contribution to the understanding of the British Security Service and, by extension, the twentieth century. In the world of smoke and mirrors, truths and lies, this is the one book that intelligence professionals need to read.

    I enjoy the professors writings, but this is a close up on an organization I'm not familiar with. I need to get out a map of London, a world atlas and an org chart to keep track of the comings and goings. For those more familiar with the British secret services, this is probably an outstanding resource. I'm still climbing a steep learning curve. I will read it again after a while.

    This book is one of the most comprehensive books ever written about an intelligence organization. It is also an authorized history meaning that MI5, the UK's domestic intelligence service actually co-operated with the author to produce this astonishingly complete history.
    It should be emphasized that MI5 has evolved considerably since its creation in 1909, but it was never simply a "domestic intelligence" organization. Its original purpose was what today is called counter-intelligence and the allied mission of keeping track of foreign residents in the UK. As the organization evolved and, in spite of missteps and pratfalls along the way, proved its worth it branched out into other duties and responsibilities. After a rather confused start MI5 performed quite well in WWI preventing sabotage, espionage and subversion by German agents. In WWII it did much the same, but also created and executed the so-called `double-cross' system of turning enemy spies into double agents. After the war it was active not only in the UK, but also in the British colonies as the UK slowly dismantled it Empire. And long before the al Qaeda terrorist movement, MI5 operatives initiated counter-terrorist strategies against both colonial terrorist movements, particularly in Malaysia and Kenya, and in the UK against the Provisional Wing of the IRA.
    The real mission of MI5 is and has always been what is called national security and its organization and mission has changed repeatedly as threats to UK national security have changed. Today MI5 responsibilities include domestic intelligence operations, executive protection, and counter-terrorism/counter-intelligence. Yet it is essential that MI5 has always avoided anything that could be called `law enforcement' or para-military operations. By avoiding these it has avoided being called a secret police organization. It is what it has always been, an organization that identifies and develops information (intelligence) on threats to UK national security and if required involves the police or military to actually counter them. MI5 often walks a very fine line between domestic intelligence and law enforcement, but for the most part has succeeded in keeping the two separate.
    This is a very fine book that provides an absolutely riveting account of a most interesting organization.

    Thoroughly enjoyable and necessary reading for those who want to know actually what our security services do.
    Although to begin with a little slow, in particular the references to committee meeting decisssions, the years of active duty are well explained and contextualised.
    Good use of humour too.
    I dont want to spoil it and by giving away the content may be contravening the secrets act.

    5.0 out of 5 stars An intelligence history written with style and authority
    Reviewed in the United Kingdom on October 24, 2010
    Professor Christopher Andrew has written an official history with style and authority and as with Professor Keith Jeffery's history of MI6, The United Kingdom's sister foreign intelligence service, the approach is as critical as it is expository. This work will remain an invaluable benchmark and reference for the history of British intelligence in the 20th century. The Security Service (MI5) should be given credit for recognising that historical analysis and narrative requires a view and understanding of the operations of covert government bodies in terms of home and foreign policy. Professor Andrew's evaluation of the damage of the Cambridge spy ring, lovingly christened 'The Magnificent Five' by their Soviet spymasters is chilling and captivating. You feel nauseated when learning how Anthony Blunt charmed his MI5 colleagues at their Second World War H/Q in St James's Street Mayfair, while systematically sacking the service of its crown jewels. While the MI5 secretaries adored him as some kind of Trevor Howard film star, he was filching out of the office over 1,700 documents to give to his NKVD case officer in the twilight of London's war-time gloom. But there was the curious irony that at the time the paranoid Soviet intelligence establishment thought the incontinent flow of secrets was too good to be true and that Blunt, Burgess, Maclean, Philby and Cairncross was playing double-cross. The greatest irony perhaps is that Sir Roger Hollis was onto Blunt; only to be personally tarred later in the maelstrom of paranoid suspicion about more Soviet moles, while Blunt enjoyed the privilege and glory of being Keeper of the Queen's pictures and an immunity cover-up lasting until 1979.
    There is so much writing and information in this 1,032 page volume that it needs to be read in bite-size chunks. But it is full of evocative and intriguing photographs and illustrations. The academic referencing and notation supports the accuracy of the sourcing rather than getting in the way of enjoying the book as historical literature.

    *****
    In the light of the scandal about fake, malicious and manipulated reviews on Amazon, I am happy to declare that I have had no contact whatsoever with the author. He is certainly a researcher and writer I admire. I purchased the copy of the book reviewed here.

    Reviewed in Germany on July 27, 2010
    Für Interessierte ein ausgezeichnetes und unverzichtbares Buch. Die authorisierte Geschichte des britischen Geheimdienstes MI5 von den Anfängen im Jahr 1909 bis zur jüngeren Gegenwart überrascht mit erstaunlicher Offenheit. Der Autor, Professor Christopher Andrew, hatte unbeschränkten Zugang zu den Archiven des MI5 erhalten und beschreibt die über 100jährige Geschichte des Dienstes auf mehr als 1000 Seiten so genau, wie es die vorhandenen Unterlagen zuließen. Es liegt in der Natur der Sache, daß die Darstellung der jüngeren Geschichte nebulöser wird und aktuellere Ereignisse der Geheimhaltung unterliegen. Für Geschichtsinteressierte und Historiker ist das Werk allein schon deshalb von Bedeutung, als meines Wissen kein anderer Geheimdienst, egal aus welchem Land, je eine vergleichbare und in weiten Teilen durchaus kritisch reflektierende Selbstdarstellung veröffentlicht hat.
