TAWA. 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. From the best opinion I can form, however, I shall
be inclined to think that the number of Fenians in the vicinity of St.
Albans never exceeded two thousand men, and that three thousand would
be a fair allowance for those assembled at Potsdam, Malone, and the
surrounding counties. The men have been represented to me as having,
many of them, served in the late Civil Wa
