We agree, however, for the reasons you have stated, that the same objection does not exist to the production of the greater part of Dr. Macnevin's memoir, and I have therefore had an extract made of such parts of it as it appears to us may be laid before the public without inconvenience....
To prevent as much as possible any occasion being given which can tend to a discovery of the channels by which this intelligence has been obtained, I most earnestly recommend to your Excellency to do your utmost in procuring that the facts which are stated from it may not stand in the report of the committees in the exact order in which they are given here, but that they may be mixed with other information which has been derived from other sources.[178]
The precautions taken to screen the betrayer were certainly very complete. Castlereagh tells Wickham (July 30, 1798):—
His Excellency authorised me to read the correspondence and memorial once over to the committee of the Commons, with a strict injunction that no person should note a single fact; and I can truly state that the individuals on that committee are altogether in the dark as to the manner in which that intelligence was obtained, and, from the mode in which it was gone through, can only have a very general impression of its contents. The same precaution was used in the Lords; and, I trust, although the Duke of Portland's despatch to his Excellency does not altogether sanction what has been done, yet that his Grace and the Ministers, who have so wisely enjoined the greatest precaution to be observed in the use to be made of that most interesting and important correspondence, will be of opinion that the guarded manner in which the Lord-Lieutenant made the communication to the committees, not authorising the smallest extracts to be made, or any of the facts to be relied on in their report, without being fully authorised by his Excellency, will preclude any danger to the State from this valuable channel of intelligence being in any degree brought into suspicion.[179]
In June 1798 Lord Edward was dead. The Sheares's had been executed. Macnevin, O'Connor, T. Addis Emmet, and Sampson lay in prison in Dublin. Blood flowed on every side. The city was like a shambles. The State prisoners, on the understanding that executions should cease, and that they might be allowed to leave Ireland, consented to reveal, but without implicating individuals, the scheme of the United Irishmen. A prolonged secret inquisition by the Secret Committee took place. As soon as their evidence appeared, Macnevin and his fellow-prisoners complained, by a public advertisement, that the Crown officials who drew up the report of the Secret Committee had garbled the facts and distorted their evidence. Into all this it is not necessary now to go, but it may be observed that, while everything inconvenient was left out, an innuendo was made that the betrayal of Dr. Macnevin's memoir may have been due to Reinhard, the French Minister. This—apart from M. Mignet's testimony to the incorruptibility of Reinhard—serves to exculpate him, and narrows the spot on which suspicion now rests. Reinhard, in his letter to De la Croix, thinks it strange that Turner had never spoken to him about certain revelations made by 'the Secret Committee of the Parliament of Ireland;'[180] but the reason now seems intelligible enough.
Macnevin published his 'Pieces of Irish History'[181] at New York in 1807, and notices the betrayal of the memorial which he had addressed to the French Government. Up to that time, and until his death in 1840, he does not seem to suspect Turner. Had any such doubt occurred to him, he would have been the first to avow it. At p. [146] of his book Macnevin inveighs against a 'profligate informer,' 'a ruffian of the name of Reynolds;' but Reynolds' treachery was confined to the arrests at Bond's in Dublin, and did not take place until March 1798. Ten pages further on Macnevin speaks of the 'unparalleled fidelity of the United Irish Body.' Dr. Macnevin was struck by the knowledge the Government had acquired of the 'negotiations of the United Irishmen with foreign States,' and, he adds, 'at this time one of the deputies [i.e. himself] had personal evidence of its extent and accuracy. That knowledge was obtained from some person in the pay of England and in the confidence of France.' And Dr. Macnevin then proceeds to point to Reinhard by name!
This is just what the officials of the Home Office wished for all along. Wickham, referring to the publication of Macnevin's memorial by the Secret Committee of the House of Lords, writes: 'It may fairly be presumed that the copy has been obtained at [the Foreign Office] Paris, or from R.'s [Reinhard's] secretary at Hamburg. This conjecture will be at least as probable as the real one.'[182]
One circumstance struck Macnevin as 'confirmation strong' of his dark suspicion. Reinhard, as he tells us, made difficulties about giving him a passport to Paris. A most important despatch from Reinhard to De la Croix thus concludes:—
What I must particularly urge, Citizen Minister, in regard to this business, is, at least, that you will have the goodness to direct me as to Mr. Macnevin. I will not give another passport without your order.[183]
