At the acme of dynastical insecurity in November 1918, when the monarchies in Austria, Bavaria, Hungary, Prussia, Saxony and Württemberg followed the Romanov empire into extinction, Sir Basil Thomson, the bristling, pushy head of Special Branch at Scotland Yard, wrote a memorandum intended for the eyes of King George V. ‘Every institution of any importance has depended during the war for its existence on an intelligence organization,’ he began with his usual bounding confidence. The Foreign Office, the Admiralty, the War Office and the Ministry of Blockade all had departments collecting data, evaluating rumours, making predictions and trying to stabilize the future. Additional officials in Downing Street were amassing political intelligence for the Prime Minister, Lloyd George. His predecessor, Asquith, had fallen from power in 1916, Thomson continued, ‘not so much because he failed in policy, as because he had no intelligence organization to keep him warned of the intrigues and movements around him’. Similarly, among factors in the recent Russian revolution and overthrow of the Romanov dynasty, defective intelligence had a leading part: ‘Petrograd was in the hands of the revolutionaries before any hint of trouble was heard at Tsarsky’ (Tsarskoye Syelo, the imperial compound outside the capital). Thomson’s lesson for the Royal Household was terse:

(1) The only safe organizations are those that possess an efficient intelligence system.

(2) Those persons or organizations that have failed to develop such systems have been destroyed.

Statecraft had mutated. Europe’s age of intelligence had begun.¹

Opposing power blocs had different explanations for these new necessities. Soviet Russia attributed the world’s great changes to the communist revolution of 1917, and to the irresistible impetus towards the dictatorship of the proletariat. The European powers attributed them to the convulsion of continental warfare in 1914–18. Certainly the clashes of the Russian, British, German and Austro-Hungarian empires, and of the French and American republics, had changed their governments’ attitudes to their populations. For centuries monarchs had levied troops to fight wars, governments had repressed civil disorder and reformers had tried to harness popular sentiments. But the military, industrial and transport mobilization of 1914–18 turned the civil population into a new concept called manpower. People of working age – women as well as men – were deployed as a war resource in factories and transport systems as well as on battlefields. The Defence of the Realm Act was enacted in London in 1914, and extended at intervals so as to manage the mass of adults to an unprecedented extent.

When the Russian revolution erupted in 1917, MI5 was focused on German espionage, subversion and sabotage. With the start of the Comintern’s international activities and the foundation of the CPGB in 1920 it changed target to Bolshevism. It relied on the police officers of the Metropolitan Police’s Special Branch, which chewed communists, anarchists, Indian nationalists, pacifists, atheists, self-important but insignificant cranks, Soho rakes, unemployed marchers and mutinous merchant seamen in its greedy, indiscriminate maw. Special Branch reports were often unimaginative if not obtuse. ‘I should wait a long, long time before acting on the advice of the present authorities at Scotland Yard,’ wrote a Tory MP, Sir Cuthbert Headlam, at the time of a botched police raid on the offices of the Soviet trading agency ARCOS in 1927. Special Branch lost control of monitoring domestic subversion after the discovery in 1929 that it had been betrayed by two Bolshevik informants, Hubert van Ginhoven and Charles Jane. Complicated cross-jurisdictional clashes between MI5 and SIS were considered at ministerial level by the Secret Service Committee in 1919, and again by senior officials in 1921, 1922, 1925 and 1927. Committee members found it hard to adjudicate between the two agencies. A resolution was not reached until Kell’s organization was named as the lead national security service in 1931.²

MI5 was primarily an advisory agency, which existed to inform government decisions and to assess and manage risks. Its staff collected, filtered, indexed and filed information gleaned from confidential informants, passport and customs officers, intercepted mail, the garbled chatter heard by covert bugging of offices and telephones, watching of addresses, shadowing of individuals and surveillance of bank accounts, public meetings and publications. Counter-intelligence officers used this data to assess the risks posed by individuals who might be subversives or spies. They resembled historians scouring documentary fragments, unravelling confused memories, checking false trails, re-evaluating doubts and discounting persecution complexes. Their re-examination of past bungles was often more informative than success stories. In the search for long-term patterns, material from multitudinous sources was assembled, allowed to fester, pondered, evaluated, deconstructed, rejected and revised. Every intelligence service was a paper-driven bureaucracy. Officers in MI5, the Cheka, OGPU and the NKVD commissioned reports, compiled profiles, read and reread their dossiers. Every small detail was committed to paper. Successful counter-intelligence usually means following a paper-trail.

The arrest of spies was not the invariable first object of counter-espionage. It was often more profitable to watch and learn. If a spy was allowed to go free, watchers could study his methods and identify his contacts. That was why SIS betrayed its inexperience of domestic counter-espionage when, in 1927, its men arrested Georg Hansen, the Soviet handler of the spy Wilfred Macartney, three days after his arrival in England, before he had found his bearings or met his contacts. Arrests might lead to exciting public denouements, but counter-espionage officers prefer to accumulate and refine intelligence rather than arrest suspects, put them on trial and thus risk disclosure of their methods.

One early example of their watch-and-learn procedure can be given. Theodore Rothstein was ‘a short, stumpy, bearded, bespectacled revolutionary who looked like Karl Marx’. Before 1914 he had collaborated with Wilfrid Scawen Blunt’s campaigns against British imperialism in Egypt and India: during the war he was a triple agent working for Lenin’s Bolsheviks, British military intelligence and the Turkish secret service. In 1919 he wished Leonard Woolf, a former colonial official turned radical activist, to publish Lenin’s recent speeches and insisted on delivering the texts in person. Woolf was instructed to walk on the inside of the pavement along the Strand eastwards towards Fleet Street on a Wednesday afternoon, timing it so that he passed under the clock of the Law Courts at 2.30. At that exact moment he met Rothstein walking westwards from Fleet Street on the outside of the pavement. Rothstein carried in his right hand an envelope containing Lenin’s speeches, which, without either man speaking or looking at each other, he transferred into Woolf’s right hand. These precautions were in vain, for Rothstein was shadowed everywhere by Special Branch and the handover was seen. A few days later the police raided Woolf’s printers and seized the documents. Although Rothstein was kept under surveillance, he had been neither arrested nor dismissed from his wartime job at the War Office: officials judged that it was better to keep him in sight rather than expel him to Russia, where out of reach he might prove a dangerous opponent. This was a pattern of behaviour that was to be repeated in cases over the next century.³

In 1919 there was a sensation when the miners’ leader Robert Smillie, as a member of the Royal Commission on the Coal Industry, browbeat three coal-mining magnates, the Duke of Northumberland, the Marquess of Londonderry and the Earl of Durham, and quoted egalitarian extracts from the Christian gospels at them. ‘The public is amused by the spectacle, but few realize its sinister significance,’ commented Hensley Henson, Bishop of Durham. ‘The very foundations of the whole social fabric are challenged. The tables are plainly turned; and it requires very little to transform the Commission into a revolutionary tribunal, and Smillie into an English Lenin … preparing an immense catastrophe.’⁴

Lord D’Abernon, who was an eyewitness to the Russian advance into Poland in 1920, felt sure that ‘Western civilisation was menaced by an external danger which, coming into being during the war, threatened a cataclysm equalled only by the fall of the Roman Empire.’ He had little hope that the European powers would forget their rivalries and combine to prevent ‘world-victory of the Soviet creed’. The communist threat to ‘England’s stupendous and vital interests in Asia’ was graver than those posed by the old tsarist regime, judged D’Abernon, for ‘the Bolsheviks disposed of two weapons which Imperial Russia lacked – class-revolt propaganda, appealing to the proletariat of the world, and the quasi-religious fanaticism of Lenin, which infused a vigour and zeal unknown to the officials and emissaries of the Czar’.⁵

There was no English Lenin. The nearest home-grown version of him was the foolhardy Cecil L’Estrange Malone. Born in 1890, the son of a Yorkshire clergyman and nephew of the Earl of Liverpool, he entered the Royal Navy in 1905, and trained as a pioneer naval aviator in 1911. He flew off the fo’c’sle of a battleship steaming at 12 knots in 1912, planned the historic bombing raid by seaplanes on Cuxhaven harbour on Christmas Day of 1914 and commanded the Royal Navy’s converted packet-steamer from which the first seaplanes flew to drop torpedoes from the air and to sink enemy vessels in 1916. He became a lieutenant colonel aged twenty-seven, and the first air attaché at a British embassy – Paris – in 1918. With this reputation for derring-do Malone was elected as a Liberal MP in the general election after the Armistice. Crossing frontiers illicitly, making night marches through forests and swamps and armed with a Browning automatic, he reached Petrograd in 1919. There he met Litvinov, Chicherin and Trotsky, visited factories and power stations under workers’ control and was converted to communism. He forsook the Liberals and joined the CPGB at its formation in 1920. He was thus the first communist MP to sit in the House of Commons (two years before the election of Walton Newbold). In October 1920 Special Branch raided his flat in Chalk Farm, and arrested Erkki Veltheim, a twenty-two-year-old Comintern courier from Finland who was in possession of seditious literature. Although Veltheim was evidently staying as a guest, Malone pretended that he was a burglar who had broken in while he was away. The young Finn was sentenced to six months’ imprisonment, and then deported. During the police search of the flat in Wellington House, they found two railway-cloakroom tickets wrapped in plain unmarked paper inside an envelope addressed to Malone. The tickets led them to parcels containing a booklet, probably written by Malone, which was a training manual for officers of a British ‘Red Army’. It contained instructions on improvised guerrilla tactics, street-fighting, execution of provocateurs and traitors, machine-gun drill, building barricades by overturning buses and trams, blockading coal-mines, seizing banks and post offices, cutting telephone and telegraph lines, and instigating naval mutinies.⁶

At a meeting organized by the CPGB and the Hands Off Russia Committee, held at the Royal Albert Hall on 7 November 1920, Malone made an inflammatory speech extolling the Bolshevik revolution and denouncing ‘the humbug’ of traditional parliamentary candidates. Capitalist manipulation of the proletariat was foundering, he averred: ‘the day will soon come when we shall pass blessings on the British revolution, when you meet here as delegates of the first all-British congress of workers, sailors and soldiers. When that day comes, woe to all those people who get in our way. We are out to change the present constitution, and if it is necessary to save bloodshed and atrocities we shall have to use the lamp-posts.’ From the Albert Hall stage he promised vengeance to an audience of over 8,000 Bolshevik sympathizers: ‘What, my friends, are a few Churchills or a few Curzons on lamp-posts compared with the massacres of thousands of human beings? … What is the punishment of these world-criminals compared to the misery which they are causing to thousands of women and little children in Soviet Russia?’ At this juncture there were cries of ‘Hang them’, ‘Burn them’ and ‘Shoot them’.⁷

Malone was arrested and tried for sedition. The prosecutor at Malone’s trial, Travers Humphreys, suggested that ‘young alien East End Jews of a disorderly type’ in the Albert Hall audience might have been roused by Malone’s violent exhortations. As to the revolutionary pamphlet, Humphreys warned that in many large British towns there were ‘persons of weak intellect, of vicious and criminal instincts, largely aliens, who will … act in response to any incitement for looting, murdering and brawling’. Malone was sentenced to six months’ imprisonment: his mother died of dismay a few weeks later. On his release he went abroad to recover, refused to respond to CPGB overtures and failed to organize a campaign to defend his parliamentary seat at the 1922 general election. Subsequently he travelled in the Balkans, visited Siberia, China and Japan, and rethought his ideas. As a Labour candidate avowing constitutionalism and disavowing extra-parliamentarianism, he was re-elected as an MP in a by-election of 1928 but lost his seat three years later. He then became an international wheeler-dealer, working for the Armenian oil millionaire Calouste Gulbenkian to extend Soviet influence in the Persian oilfields, and from 1934 served as the paid propagandist of Tokyo, running the venal East Asia News Service, defending Japan’s invasion and atrocities in Manchuria, acting as London agent of the South Manchuria Railway and operating the Japan Travel Bureau.⁸

Malone was a Lenin who took two years to fizzle out. The civil war in Ireland in 1920–2 caused little disruptive aftermath elsewhere in the British Isles. The workers’ challenge to capitalism represented by the General Strike in 1926 was only moderately divisive. The extension of the parliamentary franchise to younger women in 1927 was a voluntary act by the government rather than a sop to appease civil unrest. Demonstrations against high regional unemployment did not erupt into riots. Men parading in Trafalgar Square holding aloft banners bearing empty slogans – ‘Workers of the World, Unite’, ‘Long Live the World Solidarity of the Proletariat’, ‘Walthamstow Old Comrades’, ‘Balham Branch of the Juvenile Workers League’ – never endangered national security.⁹

Westminster and Whitehall worried, though, about Walthamstow and Balham. The police strike of August 1918, the return of demobilized troops after the Armistice in November 1918 and firebrand propagandists led to the inauguration of the Cabinet’s Secret Service Committee in February 1919 and to the formation of the Home Office’s Directorate of Intelligence, which was charged with combating domestic sedition. The Directorate’s chief Sir Basil Thomson (hitherto head of Special Branch) reported direct to the Cabinet. His summaries of opinion and sentiment from across the country – intelligence from human sources (later called HUMINT) – were a piecemeal version of the Cheka’s surveillance of opinion. In time his reports were recognized by their recipients as opinionated, subjective and contradictory. His animosity towards workers, foreigners, theoreticians, voters and those elected leaders who had the temerity to disagree with him led to increasing mistrust of his product. Suspicions that he had made disruptive, unauthorized leaks of foreign signals and communications (since known as SIGINT) prompted his dismissal in 1921. As a reaction to Thomson’s biased HUMINT, Cabinet ministers and senior officials preferred SIGINT because it seemed neutral and enabled them, if they chose, to assess it themselves without tendentious interpretations urged on them by forceful outside advisers.

Good intelligence officers remind their customers that they cannot give iron-clad guarantees about the future, although they can make informed predictions. This wariness does not make them beloved by politicians in search of certainties or by officials who want to limit the risk of mistakes. In the 1920s particularly, when Westminster politicians and Whitehall officials were still inexperienced in the techniques and benefits of intelligence-collection, SIS and MI5 were not cherished. There was more concern about subversion than about espionage. It seemed preferable to pay for police to control social disorder than to fund counter-intelligence work by MI5 or SIS. The Armistice brought slashing cuts to intelligence agencies and soaring expenditure on policing. The Secret Service Vote (money voted by parliament for the purchase of secret information in the British Isles and abroad to thwart the machinations of enemies of the nation) fell from £1,150,000 in 1918 to £400,000 in 1919 and £300,000 in 1921. It sank to £180,000 a year from 1925 to 1929. SIS expenditure fell from £766,247 in 1918 to £205,200 in 1919. It lost fifty-eight staff in the first quarter of 1919, although its Chief Sir Mansfield Cumming claimed that its commitments had increased by 300 per cent. Cumming volunteered in 1921 to reduce SIS expenditure in the coming year from £125,000 to £87,500. SIS operated from a relatively cheap house at 1 Melbury Road, on the edge of Holland Park in Kensington, during 1919–25, but thereafter found the means to occupy larger and more costly offices in Broadway, near St James’s Park and a few minutes’ walk from Whitehall and Westminster.

MI5’s budget was cut from £100,000 in the last year of the war to £35,000 in the first year of peace: it was £22,183 in 1921. These budgetary cuts were made despite the unrelenting efforts of the Bolshevik regime throughout the 1920s to spread world communist revolution, with propaganda, subversion and espionage deployed to weaken the British Empire and sundry groups and individuals enlisted to give overt or covert help in damaging British imperial capitalism. As an economy measure MI5 moved in 1919 from its offices near Haymarket, close to Whitehall and Westminster, to smaller, cheaper premises at 73–75 Queen’s Gate, Kensington, where it remained until shifting in 1929 to Oliver House at 35 Cromwell Road, Kensington. In contrast to the reduced spending on domestic counter-espionage and security, police outlay in England and Wales rose from £106,521 in 1917 to £1,159,168 in 1918, to £5,511,943 in 1919 and to £6,679,209 in 1921. Thereafter, it edged upwards to £7,239,694 in 1929.

The need to impress politicians in order to protect or expand budgets contributes to a perennial failing of intelligence services. ‘What we want’, Desmond Morton of SIS instructed the head of station in Warsaw in 1920, ‘is absolutely inside information or none at all … if you start with the idea that nothing that ever appears in a newspaper is of the least value, I am sure everything will be all right.’ This was not invariably sound procedure. ‘S.I.S. values information in proportion to its secrecy, not its accuracy,’ Stuart Hampshire was recorded as telling his wartime intelligence chief Hugh Trevor-Roper in 1943. ‘They would attach more value, he said, to a scrap of third-rate and tendentious misinformation smuggled out of Sofia in the fly-buttons of a vagabond Rumanian pimp than to any intelligence deduced from a prudent reading of the foreign press.’ The eighth of the ten commandments of intelligence propounded by the SIS veteran Brian Stewart made the same point more prosaically: ‘secret and official sources have no monopoly of the truth. Open, readily accessible sources are also important.’ This was a lesson that the Intelligence Division had first taught in the 1870s.¹⁰

With depleted budgets, the activities of both MI5 and SIS were kept peripheral to central government, although anxieties about Bolshevism were rampant throughout the 1920s. ‘We naturally ascribe all of our ills to this horrible phantom,’ wrote the industrialist-aristocrat and former Cabinet minister Lord Crawford in 1927, ‘always lurking in the background, and all the more alarming because it is tireless and unseen.’ Diplomatic relations between London and Moscow were likened by Vansittart in 1934 to that of card-players whose opponents kept a fifth ace up their sleeves and a Thompson sub-machine gun under the table. Yet there was no anti-communist section operated by SIS in 1939.¹¹

Special Branch officers were often prejudiced, but unlike J. Edgar Hoover’s Federal Bureau of Investigation they had no programme to harass, entrap and incriminate. State underfunding of the intelligence agencies during the 1920s nudged them into closer reliance on right-wing individuals and organizations than was desirable. Instead of picking and paying trustworthy agents, they had to use (although they dared not rely on) dubious informants. There were unsavoury, self-dramatizing confidence-tricksters making quick improvisations on their way to the main chance. One example is a young public schoolboy named James McGuirk Hughes. In 1923 he posed as ‘a Red’, and claimed membership of the CPGB so as to penetrate Liverpool trade unionism and remit secret reports to the super-patriotic British Empire Union. He was part of a gang associated with the future MI5 agent-runner Maxwell Knight which repeatedly burgled and wrecked the Glasgow offices of the CPGB. Hughes supplied ‘oddments of information’ to MI5, which mistrusted him as a boastful and indiscreet ‘windbag’. When in 1926 he failed to get on to the payroll of MI5 or the Daily Mail, he convinced Sir Vincent Caillard, financial comptroller of the armaments company Vickers and former officer in the old Intelligence Division, that he could supply dirt on workers’ militancy. Caillard gave him a retainer of £750 a year, with an additional £750 to pay informants (which Hughes probably pocketed).¹²

Another unreliable informant was George McMahon @ Jerome Bannigan, who supplied Special Branch and MI5 with bogus information about gun-running to Ireland and about a communist plot to disrupt the Trooping of the Colour. He was arrested in 1936 after hurling a loaded revolver at King Edward VIII in St James’s Park as part, so he claimed, of a Nazi conspiracy. At McMahon’s trial Sir Donald Somervell, the Attorney General, was determined to suppress mention in court of either Moscow or Berlin and to stop indiscretions about McMahon’s earlier use as an informant: ‘We did not particularly want the names of our emissaries whom he had seen to come out, or the previous history,’ Somervell noted.¹³

The security services understood – as Special Branch seldom did – the necessity of evaluating the trustworthiness of informants. Material from a paid informant named Kenneth Stott @ MARMION began to be supplied, through a trusted intermediary, to Desmond Morton of SIS in 1922. Stott informed on militant Scottish trade unionism, secret German industrial activities, the Brotherhood of Russian Truth, German secret agents and the French intelligence service. ‘He is badly educated, his personal conceit is enormous and his methods are unscrupulous and peculiar,’ Morton was warned in 1923. ‘While Stott’s knowledge of the Labour movement in this country is undoubtedly very extensive … his knowledge of foreign espionage methods seems to be sketchy.’ When he named suspects he allowed colourful ‘imagination and animus to have full play’. He was accordingly dropped by SIS in 1923; but, like Hughes, he continued to be paid by a credulous rich man, Sir George Makgill, for titbits on trade union conspiracies until 1926.¹⁴

Most British military attachés were intelligent in their collection and sifting of material. Charles Bridge, the cavalry officer who was Military Attaché at Warsaw and Prague until 1928, when he went to run the foreign intelligence operations of the Vickers armaments company, spoke French, German and Italian, with a smattering of central European languages. When he left Vickers in 1934, it was to become inaugural secretary general of the British Council, in which post he was able to place informants and cultivate ‘Friends’ across Europe. Bridge, it was said, had ‘the energy and exactitude of a first-rate staff officer, the courtesy and knowledge of the world expected of a military attaché, and … an indefinable mixture of devilry and charm’.¹⁵

Equally impressive was James (‘Jimmy’) Marshall-Cornwall, the Military Attaché at Berlin in 1928–32, who spoke French, German, Italian, Dutch, Norwegian, Swedish, Turkish, modern Greek, Chinese and colloquial Arabic. Although he knew how to open sealed envelopes without detection and how to tap telephone and telegraph lines, as Military Attaché he had no need of ancillary skills such as burgling safes, forging passports and concocting invisible ink. His reports never failed to interest. ‘The National-Socialist Movement is a real danger, and far more of a menace to the present constitution than is Communism,’ he reported from Berlin to the Foreign Office as early as 1930. ‘The trouble about the “Brown Shirts” is that their principles and theories are entirely destructive. They wish to destroy the present fabric of the State, but have no constructive programme with which to replace it, except a sort of mad-dog dictatorship.’ The Nazis were, Marshall-Cornwall advised, ‘far more akin to Bolshevism than to Fascism’. As to Hitler, ‘He is a marvellous orator, and possesses an extraordinary gift for hypnotizing his audience … Even though his policy is a negative one, his personal magnetism is such as to win over quite reasonable people to his standard, and it is this which constitutes the chief danger of the movement.’ Subsequently Marshall-Cornwall wrote a thoughtful treatise on geography and disarmament. In 1943 he was transferred from a post in the Special Operations Executive to be Assistant Chief of SIS.¹⁶

The Admiralty’s grasp of naval intelligence was weaker than the War Office’s hold on military intelligence, perhaps for lack of the sound traditions derived from the old Intelligence Division and possibly for lack of brainpower. ‘All simple-minded, religious, semi-literate, and amazingly unadaptable’, concluded Harold Laski of the London School of Economics after lunching at the Admiralty in 1929. ‘No doubt they are technically superb,’ he conceded, ‘but they never see beyond their noses.’¹⁷

Sir Robert Bruce Lockhart, who had been acting Consul General in Moscow when it became the Soviet Union’s capital in 1918 and survived a month’s imprisonment in the Lubianka, exchanged confidences during the 1930s with ‘Commander Fletcher … of the Secret Service’. Reginald (‘Rex’) Fletcher had become a Royal Navy cadet in 1899 aged fourteen. After wartime service on destroyers in the Dardanelles, he became post-war head of the Near East section of the Naval Intelligence Division. He sat as Liberal MP for Basingstoke in 1923–4, became an SIS officer supervising overseas operations, joined the Labour party in 1929 and was elected as Labour MP for a Midlands mining constituency in 1935. During the 1930s he worked at SIS headquarters in Broadway during the morning before crossing Westminster to the House of Commons in the afternoon. Fletcher and Bruce Lockhart agreed in their response when, in 1936, Admiralty intelligence became excited by obtaining ‘absolute proof’ of a secret treaty between Italy, Germany and Franco whereby Italy was to receive the Balearics and Ceuta and Germany the Canary Islands in return for helping the Nationalists in the Spanish civil war. ‘No intelligence reports can be taken at more than twenty per cent of truth,’ commented Bruce Lockhart, when the story reached him. ‘Secret treaties, etc., are the kind of thing intelligence officers keep supplying all the year round.’ Fletcher of SIS told him, ‘Admiralty Intelligence is particularly bad, no grey matter in it.’ Rear Admiral Sir James Troup, Director of Naval Intelligence, ‘however good he may be as a sailor, is an absolute child about intelligence’. In 1938, using SIS sources while explicitly denying that he had access to any intelligence sources, Fletcher contributed an essay on European air power (containing strictures on the Air Ministry) to a rearmament survey entitled The Air Defence of Britain. The savagery of his Commons speech in January 1939 attacking Chamberlain’s policy of appeasement was remarkable as coming from an SIS man. The Foreign Office’s liaison with SIS Patrick Reilly perhaps had Fletcher (afterwards Lord Winster) in mind when he later wrote of ‘that dangerous type often found in Naval Intelligence, the Commander passed over for promotion, bitter because he thinks, probably rightly, that he is cleverer than his contemporaries who have been promoted’.¹⁸

Starting in 1919 SIS officers were installed in British embassies and legations under the guise of passport control officers (PCOs). Many heads of diplomatic missions mistrusted the PCOs’ activities being run under cover from their buildings. A few PCOs were gung-ho buffoons, several were spivs, but others were discreet and conscientious. Ambassadors and heads of legations however preferred formal sources of official information, received unofficial confidences which they could evaluate for themselves and disliked material of obscure and untested origins which might mislead when transmitted to London. They further feared that sub rosa activities by PCOs might cause diplomatic incidents or compromise the mission. This attitude was so pronounced that in 1921 the Foreign Office (codenamed ZP inside SIS) sent a circular to all its embassies and legations in Europe which outlined its attitude to espionage during the 1920s. ‘Today the old type of Secret Service has disappeared, and melodrama has given place to a more sober style of enquiry from which the diplomat need no longer, as he was very properly required to do before, withdraw the hem of his garment,’ wrote the PUS, Sir Eyre Crowe. ‘It is largely concerned with subterranean revolutionary movements and individuals, and instead of spying on the military defences of individual countries, devotes itself principally to detecting tendencies subversive of the established order of things, irrespective of whether these are directed against the United Kingdom or are International in character.’ This circular did little to reduce the hostility of traditional diplomats to spies operating in their territories. As one example, Sir Tudor Vaughan, the British Minister to Latvia, was outraged by the breach of propriety and possible complications when the files of the SIS station in Riga were moved for safety to the legation after the ARCOS raid in 1927.¹⁹

In addition to the PCOs, Admiral Sir Hugh (‘Quex’) Sinclair, Chief of SIS in 1923–39, financed the parallel Z Organization – a network of businessmen based overseas, acting as informants and collecting Friends who could amplify their reports. Claude Dansey, the PCO at Rome, left his post in 1936 with the cover story that he had been caught embezzling SIS funds. He subsequently opened an import-export business based at Bush House in the Strand, from which he ran the Z Organization. Dansey was a self-mystifying and sinister man: ‘I’m sure he’s very clever & very subtle, but I have no proof of it because I can’t hear 10% of what he says’, wrote Sir Alexander Cadogan, PUS of the Foreign Office, at the time of Dansey’s appointment as wartime Vice Chief of SIS.²⁰

The successes of the Admiralty’s wartime code-breakers, known as ‘Room 40’, are celebrated. Their greatest SIGINT coup came in 1917 with the interception of the Zimmerman telegram, in which the German Foreign Minister promised to award three southern USA states to Mexico if it joined the Germans and declared war on the USA. The War Office’s MI1B did equally important work. The two sections, which veered between cooperation and rivalry between the wars, were merged into one agency, the Government Code and Cypher School (GC&CS), in 1919. It was swiftly recognized as the most secretive and effective British intelligence agency. The Russian section of GC&CS was led in the 1920s by a refugee from the 1917 revolution, Ernst Fetterlein, who had decrypted British diplomatic material in the tsarist cabinet noir before decrypting Bolshevik diplomatic messages for the British. For most of the inter-war period the Chief of SIS, Admiral Sinclair, was also Director of GC&CS. GC&CS had no more immunity from histrionic fantasists craving attention than other security services. One Cambridge mathematician and GC&CS officer, who committed several indiscretions in 1938–40, had ‘a kind of secret service kink’, Guy Liddell noted. ‘He likes to imagine himself as a cloak-and-dagger man, and is given to relating hair-raising stories about himself which have absolutely no foundation in fact.’ He also drank Chartreuse by the bottle.²¹

Lord Curzon of Kedleston, Foreign Secretary in 1919–24, was as peremptory and touchy as minor royalty, but unfortunately without their laziness. During 1920 he became wrathful about the deciphered wireless messages exchanged between Moscow and the Soviet trade delegation in London. ‘That swine Lloyd George has no scruples or shame in the way he deceives,’ Lenin declared in one intercepted message. ‘Don’t believe a word he says, but gull him three times as much.’ Lloyd George was nonchalant about the insults; but eight messages from Lev Kamenev, the head of the Moscow communist party (who was in London for the trade negotiations), referring to the CPGB and to Moscow’s secret subsidy of the Daily Herald, inflamed Curzon and other extreme anti-Bolsheviks in the Cabinet. They insisted on publication of these incriminating messages: a rash, flamboyant gesture which betrayed to Moscow that its codes had been broken. Alastair Denniston, head of GC&CS, blamed the short-term Kamenev publicity coup for the plummeting output of deciphered Soviet radio traffic after 1920. Thereafter, although GC&CS intercepted much secondary material on Asia and Bolshevik subversion in the British Empire, it was weak on central Europe. In addition to Curzon’s blunder, it seems likely that White Russians, who had been captured by Bolshevik forces in Crimea and had been indiscreetly told by their English contacts of GC&CS’s cryptographic abilities, disclosed that the English could understand most secret Bolshevist signals.²²

Further political indiscretions jeopardized GC&CS’s good work in decoding intercepted signals traffic: in 1922 more Soviet decrypts were published by the London government; on 2 May 1923 Curzon sent a formal protest about Bolshevik subversion in Britain to the Soviets. This so-called Curzon Note was the first protest by one government to another that acknowledged that it was based on the intercepted radio traffic of the recipient nation. There were further calamitous revelations about signals interception at the time of the police raid in 1927 on the London offices of the All Russian Co-operative Society (ARCOS) searching for purloined secret official documents. Cabinet ministers quoted from Soviet diplomatic dispatches that had been sent from London to Moscow in code. The Soviet Union dropped its encryption procedure and introduced the more secure one-time pad method.

The Foreign Office replaced the Admiralty in 1922 in its supervision of GC&CS. There was no one of sufficient seniority there to halt the misjudged disclosures of 1922–3 and 1927. The three old-guard diplomatists who served as PUS at the apex of the Office hierarchy during the 1920s, Sir Eyre Crowe, Sir William Tyrrell and Sir Ronald Lindsay, regarded intelligence as a subordinate aspect of diplomacy. They doubtless agreed with the Berlin Ambassador, Lord D’Abernon, that ‘the Secret Service’ product was ‘in a large majority of instances of no political value, based mainly upon scandal and tittle-tattle, and prepared apparently with no discrimination as to what is really important’. By contrast, the rising younger men of the 1920s understood the value and necessity of secret intelligence. Vansittart, who replaced Lindsay in 1930, and Cadogan, who succeeded him, were the first PUS to value this new ingredient in statecraft. This was held against them by officials and politicians who preferred to work by their own settled assumptions and hunches. ‘No one questions Van’s patriotism,’ wrote the Cabinet Secretary, Sir Maurice Hankey, in explanation of his enforced retirement in 1938, ‘but he is apt to get rather jumpy. He pays too much attention to the press of all countries and to S.I.S. information – useful pointers in both cases, but bad guides.’²³
