ly nation like Mexico of a
considerable portion of her territory," and protesting against the
resolution of annexation as being an act "whereby the Province of Texas,
an integral portion of the Mexican territory, is agreed and admitted
into the American Union;" and he announced that as a consequence his
mission to the United States had terminated, and demanded his passports,
which were granted. It was upon the absurd pretext, made by Mexico
(herself indebted for her independence to a successful revolution), that
the Republic of Texas still continued to be, notwithstanding all that
had passed, a Province of Mexico that this step was taken by the Mexican
minister.

Every honorable effort has been used by me to avoid the war which
followed, but all have proved vain. All our attempts to preserve peace
have been met by insult and resistance on the part of Mexico. My efforts
to this end commenced in the note of the Secretary of State of the 10th
of March, 1845, in answer to that of the Mexican minister. Whilst
declining to reopen a discussion which had already been exhausted, and
proving again what was known to the whole world, that Texas had long
since achieved her independence, the Secretary of State expressed the
regret of this Government that Mexico should have taken offense at the
resolution of annexation passed by Congress, and gave assurance that our
"most strenuous efforts shall be devoted to the amicable adjustment of
every cause of complaint between the two Governments and to the
cultivation of the kindest and most friendly relations between the
sister Republics." That I have acted in the spirit of this assurance
will appear from the events which have since occurred. Notwithstanding
Mexico had abruptly terminated all diplomatic intercourse with the
United States, and ought, therefore, to have been the first to ask for
its resumption, yet, waiving all ceremony, I embraced the earliest
favorable opportunity "to ascertain from the Mexican Government whether
they would receive an envoy from the United States intrusted With full
power to adjust all the questions in dispute between the two
Governments." In September, 1845, I believed the propitious moment for
such an overture had arrived. Texas, by the enthusiastic and almost
unanimous will of her people, had pronounced in favor of annexation.
Mexico herself had agreed to acknowledge the independence of Texas,
subject to a condition, it is true, which she had no right to
