Conclusive proof of ‘Black Diaries’ forgery, finally. By Paul Hyde. Among the diaries attributed to Roger Casement there is a cash ledger for 1911 which is also part diary. This has been scrutinised by several authors, most closely by Jeffrey Dudgeon, the Belfast researcher who is today the leading forgery denier. In 2002 Dudgeon published the first edition of his book bearing the title ‘Roger Casement: The Black Diaries – with a study of his background, sexuality and Irish political life’. This substantial volume purported to add rich detail and colour to the already widely established view that the diaries were authentic. Dudgeon was able to present much information about the north of Ireland in relation to Casement and also to provide something missing from other studies – what it was like to be an active homosexual in the North (and elsewhere) a hundred years ago. Dudgeon’s history recipe freely mixes fact with speculation and ‘in-the-know’ innuendo to promote his desired conclusions of authenticity which are guided more by an obvious bias than by impartial analysis. His book, although stylistically challenging and idiosyncratic, has gathered both attention and praise. A certain sentence on page 285/6 had disappeared. Dudgeon has never doubted the diaries are genuine and he no doubt believes he has demonstrated their authenticity to the highest degree possible. As the years passed his reputation grew as a veteran crusader who knew ‘the inside story’ and he became an influential expert consulted by authors, academics, journalists, guest speaking at conferences and appearing on the media. Such a success story that by the centenary year of 2016, he produced a second edition to meet steady demand. Then, only two years later in early 2019, he produced a third edition. There was however one small difference in this third edition. A certain sentence on page 285/6 had disappeared. The 27-word sentence, apparently insignificant, had been in print for 17 years but was deleted in 2019. To discover the motive for this unexplained deletion is also to discover its significance for the entire controversy about the diaries. The devil is in the detail we are told so let us look at the detail to find the devil. The detail concerns an alleged affair between Casement and a young Belfast bank clerk called Millar; Casement did indeed know Millar and his mother through shared friends and acquaintances in Antrim but they had little in common politically. Readers of ‘Anatomy of a lie’ will recall that the widely-believed story fabricated by MI5 agent Major Frank Hall and promoted by Dudgeon is logically demonstrated to be manufactured evidence. The alleged affair features in the 1910 diary and in the 1911 ledger with events located in Belfast and environs. The story also involves a motorcycle owned by Millar in 1911 which vehicle was identified by Hall in 1915 along with the full name of its owner, Joseph Millar Gordon. Hall passed this information to the cabinet meeting on 2 August 1916 to overcome lingering doubts about the expediency of an execution next morning. Hall’s tactic succeeded. § In the ledger the following appears dated 3 June: “Cyril Corbally and his motor bike for Millar £25.0.0″. Cyril Corbally was a noted croquet player from County Dublin who in 1910 worked at Bishop’s Stortford Golf Club in Essex. In 1910 he acquired a second-hand Triumph motor cycle registered with Essex County Council. In 1911 Corbally sold the machine and in July Millar registered ownership with the same Council. The sentence is understood to mean that the diarist is paying £25 to Corbally to purchase his motorcycle for Millar. Research has confirmed that £25 is a realistic price in 1911 for a three-year-old Triumph motorcycle; a new machine in 1908 cost around £50. However, as a simple record of a purchase the sentence is suspect because it contains four items of information when two would have been sufficient. It was not necessary to record the vendor’s name, the item bought, the purpose of the transaction and the sum paid. The vendor’s name and the price would have been enough to record the purchase. The extra information – purpose and item bought – is superfluous unless intended for third parties who the diarist knows will read the ledger. In short, the sentence is an artifice. There are two further references to the alleged transaction in the ledger: on June 8 which reads ‘Carriage of motorbike to dear Millar. 18/3’ and at the end of June ‘Epitome of June A/C Present etc. to others Cyril Corbally…25.0.0.’ Outside the ledger there is no evidence that Casement ever contacted Corbally; nor is there any reference to the purchase of a motorcycle. § Here is the sentence which Dudgeon deleted from his third edition of 2019. “It is possible that Millar bought the motor bike from Corbally and that Casement was repaying him as a separate note listing expenditure simply reads ‘Millar 25.0.0′”. This sentence published by Dudgeon from 2002 to 2019 fatally compromises his overall endeavour to persuade us of authenticity. It signifies serious confusion; he does not know who paid for Millar’s motorcycle. It also signifies that he admits the possibility that Casement did not pay Corbally as alleged in the ledger which therefore would be a forgery. This confusion signals that Dudgeon is unable to make sense of the ledger and consequently has lost faith in his project. He cannot explain why if Millar paid Corbally, the ledger records that Casement also paid Corbally. It is possible that an astute, well-meaning reader alerted Dudgeon to the fatal implications of that sentence but after 17 years it seems improbable that he suddenly discovered the gaffe by himself. That ‘separate note’ is a single handwritten page in the National Library of Ireland (NLI) described as Rough Financial Notes by Roger Casement (MS 15,138/1/12). It is inscribed on both sides with records of outgoing payments. Many of the ten undated payments record substantial amounts so that Millar’s £25 is not exceptional. The NLI
