some one of our posts so distant from any other as
to prevent the possibility of timely succor or reenforcements,
and in this way our gallant Army would be exposed
to the danger of being cut off in detail; or if by
their unequaled bravery and prowess everywhere exhibited
during this war they should repulse the enemy, their
numbers stationed at any one post may be too small
to pursue him. If the enemy be repulsed in one
attack, he would have nothing to do but to retreat
to his own side of the line, and, being in no fear
of a pursuing army, may reenforce himself at leisure
for another attack on the same or some other post.
He may, too, cross the line between our posts, make
rapid incursions into the country which we hold, murder
the inhabitants, commit depredations on them, and then
retreat to the interior before a sufficient force
can be concentrated to pursue him. Such would
probably be the harassing character of a mere defensive
war on our part. If our forces when attacked,
or threatened with attack, be permitted to cross the
line, drive back the enemy, and conquer him, this
would be again to invade the enemy’s country
after having lost all the advantages of the conquests
we have already made by having voluntarily abandoned
them. To hold such a line successfully and in
security it is far from being certain that it would
not require as large an army as would be necessary
to hold all the conquests we have already made and
to continue the prosecution of the war in the heart
of the enemy’s country. It is also far
from being certain that the expenses of the war would
be diminished by such a policy. I am persuaded
that the best means of vindicating the national honor
and interest and of bringing the war to an honorable
close will be to prosecute it with increased energy
and power in the vital parts of the enemy’s
country.
In my annual message to Congress of December last
I declared that—
The war has not been waged with a view to conquest,
but, having been commenced by Mexico, it has been
carried into the enemy’s country and will be
vigorously prosecuted there with a view to obtain an
honorable peace, and thereby secure ample indemnity
for the expenses of the war, as well as to our much-injured
citizens, who hold large pecuniary demands against
Mexico.
Such, in my judgment, continues to be our true policy;
indeed, the only policy which will probably secure
a permanent peace.
It has never been contemplated by me, as an object
of the war, to make a permanent conquest of the Republic
of Mexico or to annihilate her separate existence
as an independent nation. On the contrary, it
has ever been my desire that she should maintain her
nationality, and under a good government adapted to
her condition be a free, independent, and prosperous
Republic. The United States were the first among
the nations to recognize her independence, and have
always desired to be on terms of amity and good neighborhood
with her. This she would not suffer. By her
