Pitt was out of town. He returned, however, in a few days. Downshire immediately saw him, and Pitt consented that 'the person's' services should be accepted. There was some little delay. 'The person' took alarm, disappeared, and they supposed that they had lost him. Three weeks later, however, he wrote to Downshire from Hamburg, saying that he had returned to his old quarters, for fear he might be falling into a trap. It was fortunate, he added, that he had done so, for a letter was on the point of going over from Barclay Teeling[11] to Arthur O'Connor,[12] and he gave Downshire directions which would enable him to intercept, read, and send it on.

Such an evidence of 'the person's' power and will to be useful made Pitt extremely anxious to secure his permanent help. An arrangement was concluded. He continued at Hamburg as Lady Edward's guest and most trusted friend, saw everyone who came to her house, kept watch over her letter-bag, was admitted to close and secret conversations upon the prospect of French interference in Ireland with Reinhard, the Minister of the Directory there, and he regularly kept Lord Downshire informed of everything which would enable Pitt to watch the conspiracy. One of his letters, dated November 19, 1797, is preserved:—

'A. Lowry writes from Paris, August 11, in great despondency on account of Hoche's death, and says that all hopes of invading Ireland were given over.

'I then saw Reinhard, the French Minister, who begged me to stay here, as the only mode in which I could serve my country and the Republic. I instantly acquiesced, and told him I had arranged matters with Lord Edward Fitzgerald in London for that purpose. I showed him Lowry's[13] letter. He said that things were changed. Buonaparte would not listen to the idea of peace, and had some plan which I do not know. I told him the spirit of republicanism was losing ground in Ireland, for the Catholics and Protestants could not be brought to unite. I mentioned then what Fitzgerald told me in London, viz., that after I left Ireland they had thoughts of bringing matters to a crisis without the French. Arthur O'Connor was to have had a command in the North, he himself in Leinster, Robert Simms[14] at Belfast; that the Catholics got jealous of this, and Richard McCormick,[15] of Dublin, went among the societies of United Men and denounced the three as traitors to the cause, and dangerous on account of their ambition. All letters to or from Lady Lucy Fitzgerald ought to be inspected.

'She, Mrs. Matthieson, of this place, and Pamela[16] carry on a correspondence. Lewins, Teeling, Tennant, Lowry, Orr, and Colonel Tandy are at Paris. Tone expects to stay the winter there, which does not look like invasion. Oliver Bond is treasurer. He pays Lewins and McNevin in London. Now for myself. In order to carry into effect the scheme which you and Mr. Pitt had planned, it was requisite for me to see my countrymen. I called on Maitland,[17] where I found A. J. Stuart,[18] of Acton, both of them heartily sick of politics. Edward Fitzgerald had been inquiring of them for me. I went to Harley Street, where Fitz told me of the conduct of the Catholics to him and his friends. He said he would prevail on O'Connor, or some such, to go to Paris. If not, he would go himself in order to have Lewins removed. Mrs. Matthieson[19] has just heard from Lady Lucy that O'Connor is to come. I supped last night with Valence, who mentioned his having introduced Lord Edward and O'Connor to the Minister here in the summer, before the French attempted to invade Ireland. They both went to Switzerland, whence O'Connor passed into France, had an interview with Hoche, and everything was planned.[20]

'I feared lest Government might not choose to ratify our contract, and, being in their power, would give me my choice either to come forward as an evidence or suffer martyrdom myself. Having no taste for an exit of this sort, I set out and arrived here safe, and now beg you'll let me know if anything was wrong in my statements, or if I have given offence. If you approve my present mode of life, and encourage me so to do, with all deference I think Mr. Pitt may let me have a cool five hundred,[21] which shall last me for six months to come. To get the information here has cost me three times the sum, and to keep up the acquaintance and connections I have here, so as to get information, I cannot live on less.'[22]

The betrayer, before his interview with Downshire closed, supplied him with a list of the Executive Committee of United Irishmen. This list, duly given by Mr. Froude, includes—

Jackson and his son; Oliver Bond; John Chambers; James Dickson; Casey, a red-faced Dublin priest; Thomas Addis Emmet; Dr. McNevin, a physician who had great weight with the papists;[23] Braughall, John Keogh and R. McCormick, who belonged to the committee, though they did not attend; Samuel Turner; Lord Edward Fitzgerald; Arthur O'Connor; Alexander Stewart; two Orrs, one an attorney and a dangerous person, the other of Derry, described as a clever, sensible, strong-minded man; B. Teeling; Tenants, of Belfast; Agnew, of Larne; Lawless, Lord Cloncurry's son; Hamill, of Dominick Street[24]; Inishry,[25] a priest, a canting, designing man, who swore in Lord Edward Fitzgerald and Lawless.[26]

Lord Downshire, who negotiated in this affair, had weight with Pitt. The husband of an English peeress, and the son of Lord North's Secretary of State, he was a familiar figure at Court. He had sat for two English constituencies; and in the Irish Parliament as senator, borough proprietor, governor of his county, and one of the Privy Council, he wielded potent sway. His later history and fall belong to chapter ix.
