The main drawbacks with the ‘Official Secrets Act, 1889’ were the need to consult the attorney general before making an arrest, and the fact that ‘Even where there is moral certainty that a man is a spy… the Act does not provide for a search warrant being issued to ransack his house for incriminating documentary evidence’: Edmonds papers, IV, 4. ‘Powers possessed by the executive’ by Edmonds, [1908], P.9Google Scholar.

¹³ It is difficult to determine the precise date upon which Edmonds was transferred to MO 5. Edmonds himself suggested in his memoirs that it was late in 1906 [Edmonds papers, III, 5, ‘Memoirs’, ch. xx, p. 1] and this has been accepted by some writers [French, D., ‘Spy fever in Britain, 1900–1915’, Historical Journal xxi, 2 (1978), 356Google Scholar: Fergusson, T. G., British military intelligence, 1870–1914 (London, 1984), p. 221]Google Scholar. Other sources however give the date as 1907 [e.g. Falls, C., ‘Sir James Edward Edmonds’, Dictionary of national biography 1951–1960 (London, 1971), p. 328Google Scholar: Felstead, S. T., German spies at bay (London, 1920), p. 72]Google Scholar, and it is quite certain that Cockerill did not relinquish command of the subsection until 1 Jan. 1908 [P.R.O., ADM 116/3408, Edmonds, to Brigstocke, C. R., 16 01 1908: Edmonds papers, vii, 3Google Scholar, paper headed ‘Intelligence directory’ [1908?], p. 4]. The answer would seem to be that, in keeping with normal practice, Edmonds transferred late in 1907 and worked alongside Cockerill until assuming full control in Jan. 1908.

According to Edmonds he was advised to ‘lay stress on the anarchist [demolitions] motive’, by which sabotage was meant – although that word did not appear until 1910 or have wide usage before 1914. It is significant that the subcommittee met shortly after a widely publicized army manoeuvre at Hastings on 17 March, which Haldane attended, where Germa n spies were supposed to have blown u p railway bridges and tunnels and troops had to move against the invaders in motor cars. Then, while the subcommittee was sitting, a further military exercise was held at Scarborough on 24 April, on the supposition that the town had been invaded and that ‘As previously ordered secret agents have destroyed the rail bridges…and road bridges’, once again forcing the defending troops to move by car: Daily Mail, (17 Mar. 1909), p. 6 col. 4 and p. 7 col. 3; (18 Mar. 1909), p. 3 col. 1; North Riding Record Office (Northallerton), DC/SCB7, Scarborough town clerk's office file on ‘Auto mobilisation’, 19 Apr. 1909.

The home ports defence [sub] committee of the committee of imperial defence had begun a classification of vulnerable points in August 1909, under Hankey's chairmanship. Such preparations continued up to 1914, with the Admiralty in 1913 assigning an officer to this project full-time [Hankey, , Supreme command, 1,116Google Scholar: P.R.O., CAB 17[28, ‘List of points selected by the admiralty and the war office’, 23 Feb. 1910: Aston, G., Secret service (London, 1930), pp. 25, 55–6Google Scholar]. The MO(t) investigation of espionage in South Wales is detailed in P.R.O., ADM 1/8264, and the general conclusion, as noted by Duff, Grant, was that in 09 1911 ‘the Germans reconnoitred the district…with the intention of wrecking mines on the out break of war’Google Scholar: Grant Duff papers, AGDF 2/1, diary entry for 30 Jan. 1912.

⁷⁴ The Times, 9 Aug. 1914, p. 3 col. 4 (statement by Marie Kronauer), and detailed reports of Ernst's trial carried Sept–Nov. 1914. It is clear that Kronauer recruited Ernst as an agent in 1910, but a number of conflicting accounts have appeared about his subsequent discovery. All contain the same basic elements, and Felstead – who got information both from MI₅ and the Special Branch – may have the authentic version in his story of police following two German naval officers to Ernst's shop in May 1911, when they had come to London in the Kaiser's retinue. This event was suspicious, but does not seem to have prompted an immediate check on his correspondence, for Det.-Insp. Savage, who was closely involved with the Grosse case, recalled that Ernst was investigated ‘as a direct consequence of Heinrich Grosse's arrest’ on 4 Dec. 1911, with his significance being realized ‘immediately after’. An apparently well-informed report in 1914 stated that the interception of his correspondence began ‘about Christmas of 1911’, and this agrees with the earliest surviving intercepted letter – sent to Ernst on 6 Jan. 1912: Felstead, , In starch of sensation, pp. 88–9Google Scholar: Savage, , Savage, p. 97Google Scholar: Daily Express, (20 Oct. 1914), p. 1 cols. 3–5, ‘The Kaiser's master spy’: P.R.O., CRIM 1/151, Exhibit 7.

It seems that this document was eventually put aside when it became clear that a public statement would destroy the system of intercepted correspondence. In Feb. 1912, for instance, the check on Ernst's correspondence revealed a spy on board H.M.S. Foxhound, but Churchill nevertheless decided ‘that the case is not of sufficient importance to justify the disclosure of the means by which his correspondence with a foreign agent was detected’, and the man was not brought to trial: P.R.O., CRIM 1/151, Exhibit 10, letter to F.

First, warnings were issued in the navy about approaches from spies to dissatisfied seamen, men in debt, or those who had been severely punished, with the result that all such letters were passed on to MO(t). Secondly, British agents carried out a ‘systematic observation’ of those places in Rotterdam, The Hague, Ostend, and other towns where agents were known to meet their contacts on one occasion employing a private detective for this work: Kell papers (Frost), lecture of June 1939, pp. 5–6: P.R.O., FO 371/1909/file 8694, F.

The principle of watching without arresting endured, and although between 1911 and 1914 four spies detected through the interception of Ernst's correspondence were brought to trial, in each case MO(t) waited until there was a second, independent source of information before making an arrest – thus protecting their main operation. In Feb. 1914, for example, police arrested Frederick Gould – probably the most important German agent in Britain before the war – after incriminating papers had been found in a house he vacated in Dec. 1913, yet a letter to ‘F. Gould’ had been discovered in Ernst's, correspondence as early as 11 1912Google Scholar: The Times, (5 Mar. 1914), p. 4 col. 1: P.R.O., CRIM 1/151, Exhibit 48A, letter with enclosure posted in Berlin 16 Nov. 1912.

Some doubt has recently been thrown on the story that the arrests in Aug. 1914 broke a functioning German spy network [ French, D., ‘Spy fever in Britain, 1900–1915’, Historical Journal, xxi, 2 (1978), 364–5Google Scholar]. Whilst it cannot be proved that the men detained formed a single coherent system of espionage, there is no doubt that a large proportion were known German agents whose arrest destroyed the pre-war organization. Of the relevant officials working in Aug. 1914 this opinion is known to have been held by the head of MO(t), the deputy head of MO(t), the head of MO⁵, the director of military operations, the first lord of the admiralty, the assistant commissioner in charge of the Special Branch, the director of public prosecutions, and the home secretary: Kell papers (Frost), p. 5 of manuscript by Kell relating to ‘“Spies” in the Great War’ (n.d.); Kell papers (Simpson), ‘Security intelligence in war’ by W/ilson/, H/olt/., (1934), p. 17Google Scholar; Macdonogh, G., ‘Military intelligence’, Journal of the Royal Artillery, XLVIII (1921/1922), p. 401Google Scholar; Callwell, C.
