As these proceedings of the Government of the United States have materially tended to defeat the hostile purposes of the Fenians against this Province, I shall feel much obliged if you will convey to the Secretary of State for the United States my acknowledgments of the course which has been adopted by that Government in reference to this matter.
I have, etc...

LORD MONCK'S REPORT TO THE IMPERIAL GOVERNMENT.
In presenting his report to the Right Hon.

E.Cardwell, Secretary of State of the British Government, Lord Monck sent the following despatch, which was accompanied by the reports of the Lieutenant-General and other officers who were in command of troops during the campaign:-- OTTAWA.

June 14th, 1866.
Sir,--I have the honor to transmit for your information, the reports to the Lieutenant-General commanding Her Majesty's forces of the several officers, relating to the proceedings connected with the late Fenian invasion at Fort Erie, Canada West.

I think these documents substantially corroborate the account which I gave you from telegraphic and other information in my despatches of the 1st, 4th and 8th instant.
From all the information I have received, I am now satisfied that a very large and comprehensive plan of attack had been arranged by the party which is popularly known as the Sweeny-Roberts section of the Fenian Brotherhood.
The plan of invasion, in addition to the attempt on the Niagara frontier--the only one which actually occurred--appears to have embraced attacks on the line of the Richelieu and Lake Champlain, and also on the frontier in the neighborhood of Prescott and Cornwall, where I have reason to think the principal demonstration was intended.
For the latter object, large bodies of men, sent by railroad from almost all parts of the United States, were assembled at a place called Malone, in the State of New York, and at Potsdam, also in the State of New York, and with a view to the former, St.Albans and its neighborhood in the State of Vermont was selected as the place of assemblage.
Large supplies of arms, accoutrements and ammunition were also attempted to be forwarded by railroad to these points, but owing to the active intervention of the authorities of the United States--as soon as it became apparent that a breach of international law had been committed by these persons--a very large portion of these supplies never reached their destination.
It is not easy to arrive at a trustworthy estimate of the number of men who actually arrived at their different points of rendezvous.

It has been reported at times that there were at Potsdam, Malone, and the intervening country, as many as ten thousand men, and similar rumors have been from time to time circulated of the force at St.Albans and its neighborhood.
