105
 After the First World War, numerous authors published accounts of alleged German secret missions to Britain, most of which have since proved to be vastly exaggerated or wholly invented. In a book entitled
The Invisible Weapons
, published in 1932, Jules Crawford Silber claimed he had conveyed a wealth of critical information to Berlin which he had obtained while working as a British censor in Edinburgh. Dr Boghardt, among others, has doubted the truth of Silber's claim, arguing that there is no trace of a ‘Silber' in German archives, and pointing out that Silber revealed in his book only information that was already in the public domain. In the wartime censors' office the names of known German agents and their addresses were written on large blackboards, for all the censors to see. Had this information really been passed to German intelligence, it would presumably have lost fewer of its main British agents. As Boghardt notes, however, German records on the 120 wartime agents sent to Britain are far from complete. Boghardt,

 F Branch Report, TNA KV 1/36. By August 1915, F Branch, headed by Holt-Wilson, contained six officers and seven clerks.

113
 Branch nomenclature during MO5(g)'s rapid expansion in 1915 was fluid and somewhat confusing. On its foundation in August 1915, E Branch was commonly referred to as MO5(e). As part of a larger War Office reorganization of MO5, the three existing branches were renamed. MO5(g)A (counter-espionage) became MO5(a); MO5(g)B (aliens, DORA and preventive security) became MO5(f); and MO5(g)C (records, personnel, administration) became MO5(h). These four branches became collectively known as MI5 on 3 January 1916. ‘Historical Sketch of the Directorate of Military Intelligence during the Great War of 1914–1919', TNA WO 32/10776.
