The famous memorial of Dr. Macnevin, embracing a full report on the state of Ireland, and appealing to France for help, was written at this time.[172] On arrival at Hamburg he entrusted it to Reinhard, the French minister there, by whom--as we learn from the 'Cornwallis Papers'--it was translated and forwarded to Paris. Mr. Froude thinks its betrayal to the English Cabinet a very remarkable circumstance, and the more strange because 'no suspicion has been suggested of Macnevin's treachery.' A hidden hand contrived to pass on to Pitt this document destined to become historic.[173] Wickham, writing to Castlereagh on August 15, 1798, states that the rebel executive committee directed Dr. Macnevin to proceed to Paris by the way of Hamburg; that the principal objects of his journey were to give additional weight and credit to the mission of Lewins, and to confirm the information that had already been transmitted.[174] Again the reader may be reminded that Lewins and Turner were rival envoys. Each is found constantly trying to circumvent the other. Turner, therefore, had a special object in foiling and intercepting Macnevin's memorial. Reinhard, in the betrayed despatch of July 12, 1797, tells De la Croix, at Paris, that every confidence might be reposed in Lewins. Lewins' usual post was at Paris, just as Turner's was at Hamburg, but both passed to and fro. Of Lewins, Reinhard takes care to say that Macnevin not only attested that he possesses, and deserves, the utmost confidence, but that he is designated a minister at Paris in case of success. Mr. Macnevin wished much that his memorial should be communicated to him.[175] If it was Turner's interest to intercept Reinhard's letter establishing confidence in Lewins, it was still more his interest to keep back from Lewins a document which, while vindicating his name, would protect it from further attack; and this the 'Memorial' of Macnevin was designed to do. Camden had now ceased to be Viceroy and was succeeded by Cornwallis.[176] The latter co-operates with the Home Secretary in screening from publicity the name of their informer. The report of the Secret Committee was now in progress. Cornwallis, writing to Portland, says:-- The same reason may not operate against the production of Dr. Macnevin's memoir, which might be supposed to have fallen into our hands by various other means, and which, from its being produced, without connection with the other papers, might not create any alarm in the quarter where it is so necessary that the most implicit confidence in our prudence and secrecy should be preserved. Your Grace will of course be aware that no account will be given, even to the Secret Committee, of the means by which these papers came into the hands of Government.[177] Portland duly acknowledged Lord Cornwallis's despatch,
