to make known to you an equally
satisfactory conclusion in the case of the _Caroline_ steamer, with the
circumstances connected with the destruction of which, in December,
1837, by an armed force fitted out in the Province of Upper Canada, you
are already made acquainted. No such atonement as was due for the public
wrong done to the United States by this invasion of her territory, so
wholly irreconcilable with her rights as an independent power, has yet
been made. In the view taken by this Government the inquiry whether
the vessel was in the employment of those who were prosecuting an
unauthorized war against that Province or was engaged by the owner in
the business of transporting passengers to and from Navy Island in hopes
of private gain, which was most probably the case, in no degree alters
the real question at issue between the two Governments. This Government
can never concede to any foreign government the power, except in a case
of the most urgent and extreme necessity, of invading its territory,
either to arrest the persons or destroy the property of those who may
have violated the municipal laws of such foreign government or have
disregarded their obligations arising under the law of nations. The
territory of the United States must be regarded as sacredly secure
against all such invasions until they shall voluntarily acknowledge
their inability to acquit themselves of their duties to others. And in
announcing this sentiment I do but affirm a principle which no nation on
earth would be more ready to vindicate at all hazards than the people
and Government of Great Britain. If upon a full investigation of all the
facts it shall appear that the owner of the _Caroline_ was governed by
a hostile intent or had made common cause with those who were in the
occupancy of Navy Island, then so far as he is concerned there can be no
claim to indemnity for the destruction of his boat which this Government
would feel itself bound to prosecute, since he would have acted not only
in derogation of the rights of Great Britain, but in clear violation of
the laws of the United States; but that is a question which, however
settled, in no manner involves the higher consideration of the violation
of territorial sovereignty and jurisdiction. To recognize it as an
admissible practice that each Government in its turn, upon any sudden
and unauthorized outbreak which, on a frontier the extent of which
renders it impossible for either to have
