From the letter just quoted it appears that, after his efforts to pick news from Talleyrand and fish in Irish channels at Paris, he returned, _viâ_ Cuxhaven, to London, where he arrived on Tuesday night, May 15, 1798. This date is worthy of note. The spy feared to show himself in London and felt that his life was unsafe. What brings him back to London on May 15, 1798? His favourite post was Cuxhaven or Hamburg. O'Coigly, Binns, and Leary, though arrested in March _en route_ to France, were not put on their trial until Monday, May 21, 1798. This case is reported at extraordinary length in Howell's 'State Trials' and would fill a volume. Scott, afterwards Lord Eldon, prosecuted. The mass of secret information which the Crown contrived to acquire strikes very forcibly. Letters written in cipher by O'Coigly to Lord Edward Fitzgerald and others are translated and expounded by Scott. All the parties concerned in the conspiracy had false names. Mrs. Mathiessen[83] is called 'Marks;' 'a man going to William's,' means 'going to France,' etc. It was largely on evidence of this sort that O'Coigly was convicted and hanged.[84] The betrayer tells Talleyrand that 'the spirit of the North was completely broken.' In point of fact, however, it was in the North that the real martial spirit of the United Irishmen blazed, and there the best battles were afterwards fought under the leadership of Orr and Monroe. Turner was anxious to make the French turn their thoughts of invasion to other points on the Irish coast, and he so far succeeded that in August, 1798, Humbert's expedition, embracing not 1,000 men, landed at Killala, among the starved and unarmed peasantry of Connaught. He calculated on meeting enthusiastic support; but, as Mr. Lecky says, it soon became apparent how fatally he had been deceived. After winning one battle, and losing another, Humbert surrendered to Cornwallis. 'May I assure them that you'll come in three months?' Talleyrand is asked. The object of this and other questions, which, to a casual reader, seem hardly consistent with Turner's treachery to his friends, is now pretty plain. Great doubt prevailed as to whether an invasion of Ireland was really to be attempted. The First Consul blew hot and cold upon it. If the spy, as an envoy of the United Irishmen, could only extort from Talleyrand an explicit reply in writing avowing the intention to invade, and telling the exact time on which the descent on Ireland was to be made, England would thus be well prepared, and her fleet able to destroy the French armament as she had already destroyed that of De Winter. Why Bonaparte, at first so anxious for invasion, should have changed his mind, is explained, in the recently published Memoirs of Gouverneur Morris, as due to the conflicting reports of Irish envoys. At St. Helena he told Las Cases that his mistake in '98 was to have gone to Egypt and not to Ireland.[85]
