intelligence literature

{{Poem quote|text="Readers may be surprised to discover how much intelligence activity went on in the ancient world. Indeed, finding spies in the ancient authors is not nearly as difficult as tracking down some of the secondary literature. Articles and books on aspects of ancient intelligence activities have appeared all over the globe in more languages than one author could ever hope to read."|sign=Rose Mary Sheldon|title=Introduction|source=Espionage in the Ancient World}}

Intelligence literature is rooted in the original works of myth, folklore, oral tradition, political science and philosophy, as spycraft has always been a tool of statecraft, warfare, and diplomacy, and for the majority of its history, intelligence literature was wrapped-up into these genres. In ancient cultures, there often was no distinction between fiction and nonfiction. It took hundreds to thousands of years for it to become its own, unique, genre of literature.

The Story of Wenamun is a Hieratic Late Egyptian literary text that focuses on Wenamun, a priest of Amun at Karnak, is sent by the High Priest of Amun Herihor on a secret mission to the Phoenician city of Byblos to acquire lumber (probably cedar wood) to build a new ship to transport the cult image of Amun. After visiting Smendes (Nesbanebded in Egyptian) at Tanis, Wenamun stopped at the port of Dor ruled by the Tjeker prince Beder, where he was robbed. Upon reaching Byblos, he was shocked by the hostile reception he received there. When he finally gained an audience with Zakar-Baal, the local king, the latter refused to give the requested goods for free, as had been the traditional custom, instead demanding payment. Wenamun had to send to Smendes for payment, a humiliating move that demonstrates the waning of Egyptian power over the Eastern Mediterranean; a causative factor of a new nature can be seen in this ebbing of Egyptian power — the rise of Assyria and its intrusion into Phoenicia around the year 1100 BCE.A. Malamat, The Egyptian Decline in Canaan and the Sea-Peoples, included in 'The World History of the Jewish People', vol. III: Judges, Rutgers University Press (1971), page 36 After a wait of almost a year at Byblos, Wenamun attempted to leave for Egypt, only to be blown off course to Alashiya (Cyprus), where he was almost killed by an angry mob before placing himself under the protection of the local queen, whom he called Hatbi. At this point the story breaks off.

Strategemata is a work by the Roman writer Frontinus, written in the 1st century, which focuses on military strategy, but does include discussions on deception and intelligence gathering.{{Cite book |last=Henderson |first=Jeffrey |url=https://www.loebclassics.com/view/LCL174/1925/volume.xml |title=Stratagems. Aqueducts of Rome |date=1925 |publisher=Harvard University Press |isbn=978-0-674-99192-7 |language=en}} This book is more accurately defined as Military history, but includes within it sections on Intelligence history. The first section of this book is entitled "On Concealing One's Plans," and the second is entitled "On Discovering the Enemy's Plans," both of which are directly related to the fields of intelligence collection and counterintelligence.{{Cite web |title=LacusCurtius • The Stratagems of Frontinus |url=https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Frontinus/Strategemata/home.html |access-date=2025-03-03 |website=penelope.uchicago.edu}}

Arthashastra ({{langx|sa|अर्थशास्त्रम्}}, {{IAST3|Kautiliyam Arthaśāstram}}) is an Ancient Indian Sanskrit treatise on statecraft, politics, economic policy and military strategy.{{Cite book |last=Kauṭalya |url=https://archive.org/details/kinggovernancela0000kaua |title=King, governance, and law in ancient India : Kauṭilya's Arthaśāstra : a new annotated translation |date=2013 |publisher=New York : Oxford University Press |others=Internet Archive |isbn=978-0-19-989182-5}} The Arthashastra explores issues of social welfare, the collective ethics that hold a society together, advising the king that in times and in areas devastated by famine, epidemic and such acts of nature, or by war, he should initiate public projectssuch as creating irrigation waterways and building forts around major strategic holdings and towns and exempt taxes on those affected. The text was influenced by Hindu texts such as the sections on kings, governance and legal procedures included in Manusmriti.

In China, the author Sun Tzu is perhaps most well known for his seminal work, The Art of War. In the Art of War, Sun Tzu suggests tactics and strategies for spies, but in the broader conception of warfighting.Giles, Lionel The Art of War by Sun Tzu – Special Edition. Special Edition Books. 2007. p. 62. The Art of War is an early inspiration for many intelligence officers and leaders of intelligence agencies, but it is not, on its own, a work of intelligence literature.

During the Crusades, the Knights Templar, which was engaged in espionage activities in the Holy Land, might have published manuals on clandestine activities.{{Cite book |last=Jones |first=Dan |url=https://books.google.com/books?id=O7CfEAAAQBAJ |title=The Templars |date=2017-09-07 |publisher=Bloomsbury Publishing |isbn=978-1-78185-890-5 |language=en}} However, after the Templar Order was disbanded in 1312 by Pope Clement V, many of their records were seized or destroyed.{{Cite web |title=Texts from the Military Orders – The French of Outremer |url=https://frenchofoutremer.ace.fordham.edu/index-of-sources/listing-by-category/texts-from-the-military-orders/ |access-date=2025-02-28 |website=frenchofoutremer.ace.fordham.edu}} Some theorists speculate that if the Templars had intelligence manuals, they were either lost or kept secret by successor groups (e.g., the Freemasons or other knightly orders).

Italian writers in the 1500s, such as Niccolò Machiavelli, Giovanni Botero, and Giovan Battista Possevino (Giovan's French Wikipedia article) published many treatises and manuals for statecraft, which did include literature surrounding the intelligence field, but might not be considered works of intelligence literature, but still bound in political science and philosophy.

Perhaps the most persistent author of this period is Machiavelli, with his collection of works including The Prince and The Art of War, both of which have inspired generations of diplomats, politicians, and spies. The Prince, upon its release, shocked the readers of Europe because it presented a moral case for ill deeds in the time of war.{{Cite book |last=Zuckert |first=Catherine H. |url=https://books.google.com/books?id=yZUtDwAAQBAJ&q=catherine+zuckert+machiavelli |title=Machiavelli's Politics |publisher=University of Chicago Press |year=2017 |isbn=978-0226434803}} Scholars often note that Machiavelli glorifies instrumentality in state building, an approach embodied by the saying, often attributed to interpretations of The Prince, "The ends justify the means".{{Cite book |last=Mansfield |first=Harvey C. |url=https://books.google.com/books?id=Q4EULB2IM50C&q=harvey+mansfield+machiavelli |title=Machiavelli's Virtue |publisher=University of Chicago Press |year=1998 |isbn=978-0226503721}} Fraud and deceit are held by Machiavelli as necessary for a prince to use.The Prince, Chapter XVIII, "In What Mode Should Faith Be Kept By Princes"

The first officially recognized, but not widely known, memoir in intelligence literature was Memoirs of Secret Service: , written by Matthew Smith in the 17th century.{{Cite web |title=Memoirs of Secret Service {{!}} Friends of the National Libraries |url=https://grants.fnl.org.uk/memoirs-secret-service |access-date=2025-02-27 |website=grants.fnl.org.uk}} Prior to this, intelligence officers did not share their secrets – but Smith submitted his manuscript to the House of Commons of the United Kingdom in order to defend himself against accusations that he had been incompetent and in league with Jacobites.{{Cite ODNB |last=Hopkins |first=Paul |date=January 3, 2008 |title=Smith, Matthew, spy and writer |url=https://www.oxforddnb.com/display/10.1093/ref:odnb/9780198614128.001.0001/odnb-9780198614128-e-25877 |access-date=2025-02-25 |language=en |doi=10.1093/ref:odnb/25877}} in which he had been called to testify in front of the House of Lords. In his memoir, he accused Charles Talbot, 1st Duke of Shrewsbury and his aide, James Vernon, of having been involved in a Jacobite assassination attempt. He opens his memoir{{Cite book |last=Smith |first=Matthew |url=https://books.google.com/books?id=iuhbAAAAQAAJ |title=Memoirs of secret service. [Followed by] The reasons why I corresponded with mr. John Hewet |date=1699 |language=en}} with the following words:

{{Poem quote|text="It is not without the last reluctancy, that I resolve to publish these papers, or rather should have said, I am oblig'd to it by the utmost Necessity. It may happen to many to have their services not rewarded; but my case is particular, who am reduced to the unhappy necessity of defending them."|sign=Matthew Smith}}

The book's bold accusations generated public interest and was even translated, but Parliament largely ignored it. In November 1699, Smith intensified his claims against the Earl of Shrewsbury in Remarks upon the D— of S—'s Letter to the House of Lords, which led to his brief imprisonment for breaching parliamentary privilege and the public burning of the pamphlet.

Despite setbacks, Smith continued publishing attacks, responding to Kingston's pamphlet with A Reply to an Unjust and Scandalous Libel in 1700. After William III’s death, he wrote a petition accusing Shrewsbury and James Vernon of treason and alleging that the late king had bribed MPs. However, fearing poor timing after William Fuller’s recent exposure as a fraud, he hesitated before submitting it to Speaker Robert Harley in March 1702. Harley ignored the claims, and with Shrewsbury overseas and Vernon out of office, the accusations faded. Smith’s fortunes later changed in 1703 when he was appointed judge-advocate of Jamaica, likely through the influence of the earl of Peterborough. However, little is known of his later years, and he is believed to have died before 1723.

John Macky (died 1726) was a Scottish spy and travel writer. Between 1688 and 1710 he ran a successful intelligence gathering network across the English Channel, principally concerned with Jacobite and French threats to England.{{Cite ODNB|doi=10.1093/ref:odnb/17632|title=Macky, John}} He was also the author of several publications which reflected his travel, political outlook and access to leading figures of the period.{{cite journal |last1=Ross |first1=Slaney Chadwick |date=2015 |title=The Secret History of the English Spy: 1674–1800 |url=https://docs.lib.purdue.edu/cgi/viewcontent.cgi?article=2710&context=open_access_dissertations |journal=Purdue University |pages=134–140 |doi= |access-date=31 August 2023}}{{cite journal |last1=Fritz |first1=Paul S. |date=1973 |title=The Anti-Jacobite Intelligence System of the English Ministers, 1715-1745 |url=https://www.jstor.org/stable/2638312 |journal=The Historical Journal |volume=16 |issue=2 |pages=265–289 |doi= 10.1017/S0018246X00005860|jstor=2638312 |access-date=31 August 2023}} Memoirs of the Secret Services of John Macky (1733) is a firsthand account of his espionage and political intelligence gathering activities during the late 17th and early 18th centuries.{{Cite book |last=Macky |first=John |url=https://archive.org/details/bim_eighteenth-century_memoirs-of-the-secret-se_macky-john_1733 |title=Memoirs of the secret services of John Macky, Esq; during the reigns of King William, Queen Anne, and King George I. ...

The most famous controversial memoir in intelligence literature is likely Spycatcher: the Candid Autobiography of a Senior Intelligence Officer, by the British spy Peter Wright. This book caused a great controversy in the United Kingdom when it was released, as it detailed aspects of the intelligence field in the era of the Cambridge Five that were damaging to the British government.{{Cite news |last=Ungoed-Thomas |first=Jon |date=2021-11-27 |title=UK officials still blocking Peter Wright's 'embarrassing' Spycatcher files |url=https://www.theguardian.com/world/2021/nov/27/inside-story-of-peter-wrights-spycatcher-blocked-by-cabinet-office-delay-and-deception |access-date=2025-02-27 |work=The Observer |language=en-GB |issn=0029-7712}}

In this memoir, Wright alleges the presence of a Soviet mole within MI5, specifically accusing former Director-General Sir Roger Hollis. The book also delves into various covert operations and internal dynamics of British intelligence. Upon its release in 1987, the British government sought to suppress its distribution, leading to legal battles and debates over press freedom.{{Cite AV media |url=https://www.youtube.com/watch?v=5gEe0zxL6CU |title=The Spycatcher Affair: MI5 The Scandal that Shook Britain with Tim Tate {{!}} SpyCast |date=2024-09-26 |last=International Spy Museum |access-date=2025-02-27 |via=YouTube}}{{Cite news |date=2023-12-29 |title=National Archives: Thatcher was desperate to stop Spycatcher publication |url=https://www.bbc.com/news/uk-67835095 |access-date=2025-02-27 |language=en-GB}}

Recent revelations have shed light on the British government's internal handling of the affair. Declassified documents indicate that Prime Minister Margaret Thatcher approved the controlled leak of information regarding the suspected mole, Sir Roger Hollis, to journalist Chapman Pincher.{{Cite web |last=Malvern |first=Jack |date=2024-08-16 |title=Margaret Thatcher approved leak of MI5 mole story |url=https://www.thetimes.com/uk/history/article/margaret-thatcher-approved-leak-m15-rml5xdgrd?region=global |access-date=2025-02-27 |website=www.thetimes.com |language=en}} This strategic leak aimed to manage public perception and preempt the disclosures in Wright's forthcoming book. Additionally, these documents reveal that Cabinet Secretary Robert Armstrong provided misleading testimony during the Spycatcher trial, denying the orchestrated leak under oath.

The government's attempts to suppress Spycatcher inadvertently amplified its notoriety. While the book was banned in England, it remained available in other regions, including Scotland and Australia, leading to widespread public interest and debate.{{Cite news |title=The Spycatcher Affair & MI5: The Scandal that Shook Britain with Tim Tate |url=https://thecyberwire.com/podcasts/spycast/650/notes |archive-url=http://web.archive.org/web/20241005090026/https://thecyberwire.com/podcasts/spycast/650/notes |archive-date=2024-10-05 |access-date=2025-02-27 |work=N2K CyberWire |language=en-US}} The affair not only highlighted internal tensions within British intelligence but also sparked discussions on press freedom, governmental transparency, and the public's right to information.

{{Main|Intelligence studies}}

Intelligence Studies is an interdisciplinary academic field that concerns intelligence assessment and intelligence analysis. Intelligence has been referred to as the "lost dimension" of the fields of international relations (IR) and diplomatic history, as the secretive nature of the subject means most intelligence successes are unknown.Evans and Newnham, p. 256. Intelligence studies comprise a small but major component of intelligence literature.{{Cite journal |last=Vogt |first=Tobias O. |date=2013 |title=Defining the Discipline of Intelligence Studies |url=https://www.jstor.org/stable/26202071 |journal=American Intelligence Journal |volume=31 |issue=2 |pages=49–53 |jstor=26202071 |issn=0883-072X}}{{Cite book |url=https://rowman.com/ISBN/9780810878969/Historical-Dictionary-of-British-Intelligence-Second-Edition |title=Historical Dictionary of British Intelligence, Second Edition |language=en-us |archive-url=http://web.archive.org/web/20211207192814/https://rowman.com/ISBN/9780810878969/Historical-Dictionary-of-British-Intelligence-Second-Edition |archive-date=2021-12-07}}

The largest collection of intelligence history remains the Intelligence History Collection (IHC), which is housed in the CIA Library, containing over 23,000 volumes.{{Cite web |last1=Sullivan |first1=Emma |last2=Warren |first2=Ward |title=The Historical Intelligence Collection |url=https://www.cia.gov/resources/csi/static/The-Historical-Intel-Collection.pdf}} This collection was mostly gathered by Walter Pforzheimer, who was often referred to by his honorific title in the intelligence world as "The Dean of Intelligence Literature."{{Cite web |title=Celebrating the Life of Walter Pforzheimer - CSI |url=https://www.cia.gov/resources/csi/studies-in-intelligence/archives/vol-47-no-3/celebrating-the-life-of-walter-pforzheimer/ |access-date=2025-02-25 |website=www.cia.gov}}

In 1954, Pforzheimer was assigned by Allen Dulles to develop the Historical Intelligence Collection, a role he held until his retirement in 1974. Pforzheimer's mandate was to develop a collection encompassing all aspects of intelligence operations and doctrine, providing a valuable resource for Agency personnel. Under Pforzheimer's leadership, the HIC expanded rapidly. In its inaugural year, the collection grew to include 3,570 volumes, with Pforzheimer personally acquiring 1,308 books during a European trip across ten countries, all for under $2,500. He defined the collection's scope to cover a wide range of topics, including military and national intelligence, espionage, counterespionage, unconventional warfare, cryptography, and various elements of intelligence tradecraft. This comprehensive approach ensured that the HIC became an unparalleled resource within the intelligence community.

When he retired, the HIC had grown to 22,000 volumes, the largest professional intelligence collection in the world. His efforts not only provided CIA officers with a rich repository of historical intelligence materials but also laid the foundation for ongoing scholarly research in the field. The Collection is now a part of the CIA Library.{{cite web |title=CIA Library |url=https://www.cia.gov/legacy/headquarters/cia-library/ |url-status=live |archive-url=https://web.archive.org/web/20210318232002/https://www.cia.gov/legacy/headquarters/cia-library/ |archive-date=March 18, 2021 |access-date=August 14, 2021 |website=Central Intelligence Agency}}
