On the morning of Saturday 25 October 1924 Philip Snowden, the Labour chancellor of the exchequer, was woken by the sound of J. H. Thomas, the colonial secretary, hammering on his bedroom door. ‘Get up, you lazy devil!’ Thomas is reported to have said. ‘We';re bunkered.’ What Thomas really said was probably more vivid but less printable. The cause of his excitement was the publication of the Zinoviev letter, the greatest Red Scare in British political history. Allegedly written by Zinoviev, president of the communist International, to the British Communist party on 15 September 1924. this sinister document instructed British Communists to put pressure on their sympathizers in the Labour party, to ‘strain every nerve’ for the ratification of the recent treaty with the Soviet Union, to intensify ‘agitation-propaganda work in the armed forces’, and generally to prepare for the coming of the British revolution. A copy of the letter was first obtained by the Daily Mail, then circulated by the Mail to the rest of Fleet Street. It was published in the press four days before the general election of 29 October 1924, at a critical moment in the life of the first Labour government. Until its publication Labour leaders felt their election campaign was going well. Afterwards they changed their minds.

A committee of the outgoing Labour cabinet, set up on 31 October to examine the letter's authenticity, found it impossible to reach a decision ‘in the short time available‘ before the government's resignation on 4 November. The committee of the Baldwin cabinet had more evidence, as well as more time, available to it.

12 S.I.S. activities were strictly confined to areas outside the United Kingdom. The special branch played no part in providing or corroborating the Zinoviev letter (SirChilds, Wyndham, Episodes and reflections (London, 1930), p. 246; Marquand, D., Ramsay MacDonald (London, 1977), p. 388. Evidence of the letter's receipt must therefore have come from M.I. 5.
13 For earlier examples of these reports, see below, pp. 692, 701. The flow of Sovnarkom minutes continued after S.I.S. had obtained a report of its discussion of the Zinoviev letter on 25 October 1924. Reports of further Sovnarkom meetings were circulated to the cabinet by Austen Chamberlain on 22 December 1924 (copy in FO 371/10480) and in January 1925 (copy in Cambridge University Library, Baldwin MSS 230). The first of these reports provided further corroboration for the Zinoviev letter. Chicherin was alleged to have told Sovnarkom that ‘the letter upon its receipt had been destroyed by Comrade Inkpin [secretary–general of the British Communist party]’.
14 The ‘irrefutable evidence‘ which the intelligence services claimed to furnish on the weekly transfer of funds from the Russian trade delegation to the British Communist party must surely have come, at least in part, from within the party (see below, p. 692). During the 1928 commons debate on the Zinoviev letter, the attorney general, Sir Douglas Hogg, appeared to hint at the previous existence of a Communist informer. He alleged that one of the reasons for the left-wing call for a government enquiry into the letter was ‘to find out who, in the ranks of the Communist party [apparently meaning the British party], gave away the secret’ (Part. Deb., H. of C, 5th series, vol. 215, col. 93).

19 Britain was not, of course, the only country to intercept Soviet communications. During the post-war period France and the United States were able to decrypt at least some Russian telegrams. A number of other governments also intercepted from time to time the correspondence of Comintern and the Soviet Communist party. Peters, the British envoy in Moscow, reported after the publication of the Zinoviev letter: ‘The general view [of the diplomatic corps] is that, whether this particular letter is or is not genuine, other letters of similar tenor are constantly being despatched by the Communist International to various countries.’ Peters reported the ‘somewhat similar case’ of a letter from the Soviet Communist party intercepted by the Finnish government in 1922, whose authenticity had at first been denied by the Russian government: ‘When it was established, by means of examination of the typewriting, that it was the work of the same machine as that on which various undoubtedly genuine circulars had been typed, the Soviet authorities took the fresh line that it was the work of a female typist, Miss Eva Korhonen, and that the committee of the party had nothing to do with it. The matter was dropped, as so many of these matters are.’ Peters to MacDonald, no. 1027, 4 Nov. 1924, FO 371/10479.
20 The extent of the expurgation varies with the type of raw intelligence. A substantial number of special branch reports have been left by the weeders. On the other hand, an attempt has been made to remove from the files all trace of intercepted diplomatic telegrams.

Kaye was director of the intelligence bureau of the Indian government's home department from 1919 to 1924; he was succeeded by Petrie from 1924 to 1931. Their books (originally distributed only to intelligence personnel) provide valuable summaries of most intelligence material available to the raj, with the notable exception of decrypted Soviet telegrams (evidently considered too secret for inclusion). The first editions of their works are available only in the Indian National Archives; there is no copy in the London India Office Library. Significantly the Indian editor of the reprint, though a Marxist, does not suggest that any of the intercepted documents cited by Kaye and Petrie (which include Comintern communications) were forgeries. Space does not permit an extended analysis of Indian intelligence work in this article.

51 Ibid., pp. 287–9. Sinclair, D.N.I. 1919–21, was already the dominating figure in British intelligence. After a brief tour of duty as chief of the submarine service he returned to intelligence work in 1923 with the official title of ‘head of the secret service’.
52 conclusions, Cabinet, 15 Sept. 1920, Cab. 23/23. This leak is not discussed by Ullman.
53 Hankey claimed that the cabinet decision not to publish the intercepts was due mainly to his warnings on the danger of ‘compromising' G.C. & C.S. Diary entry by Hankey, 15 Sept. 1920, Churchill College, Cambridge, Hankey MSS 1/5.
54 Frunze, to Lenin, and others, 19 Dec. 1920, Trotsky papers, 11, 369; Ullman, , Anglo–Soviet accord, pp. 308–9. Ullman implies that British indiscretions in September had helped alert the Russians to the breaking of their codes. This appears unlikely. The Russians did not decide to change their codes until after Frunze's warning three months later. British intelligence chiefs, unaware of Frunze's warning, naturally concluded that British indiscretions were to blame. Ullman also implies that the flow of Russian intercepts was now ‘to dry up’ for a considerable, if not indefinite, period. In fact the flow resumed less than four months later.

68 Gregory believed that one reason for the ‘almost complete lack of evidence of hostile activity by Soviet representatives in the East’ was ‘the fact that we are perhaps not now in a position to interpret the wireless messages which were the chief source for our charges in May last’ (Ibid.). The break in the flow of intercepts was to be a temporary one. How temporary, however, it is impossible to say on the basis of the evidence at present available. By the spring of 1925 G.C. & C.S. was once again decrypting Russian telegrams but it may have done so earlier. I intend to deal with the period from the Zinoviev letter to the rupture of Anglo-Soviet relations in a later article.

76 Churchill to Austen Chamberlain, 21 Nov. 1924, Chamberlain MSS AC 51/58. Churchill would scarcely have made such a claim in a letter to the foreign secretary (who could easily check it) had he been uncertain of its truth. He had been at pains to compare the circulation of intercepts under the MacDonald and first Baldwin governments in order to urge a return to the practice of the latter. The Foreign Office's motives in withholding intercepts from MacDonald for some time may, however, have been less sinister than Churchill's letter suggests. Even allowing for Crowe's deep fear of Bolshevism, his even deeper sense of personal honour would scarcely have allowed him to conceal important information from the prime minister. But since MacDonald, as part–time foreign secretary, did not deal with much day–to–day diplomacy, Crowe may have felt for some time after the loss of the Russian diplomatic codes that no intercept was sufficiently important to require the prime minister's personal attention.

90 The news of Reilly's execution during his 1925 Russian mission was revealed by an OGPU defector in 1927. It has since been confirmed by a best–selling Soviet ‘history’ of ‘OGPU. There have also been other, highly speculative, versions of how the ‘master spy’. met his fate. See Lockhart, R. Bruce, Ace of spies (London, 1967).

When and in what form a report of Zinoviev's speech (later published) reached the Foreign Office is unclear. In view of its access to much more confidential Comintern information, however, it is unlikely that the Foreign Office received no report of the speech.

Im Thurn later extracted £10,000 from Conservative Central Office, allegedly to recompense the unidentified source who had informed him of the letter and had, he claimed, subsequently taken refuge in Argentina under a false identity. The Argentina story is an implausible one. Im Thurn also sought a knighthood for his own part in the affair.
108 It is impossible to reconstruct the precise pattern of contacts between retired and serving intelligence personnel. But that there were such contacts, and that classified information reached retired agents, seems certain.
