Mexico and constituting no part of her territory or rightful sovereignty
and jurisdiction. He was also assured that it was the sincere desire of
this Government to maintain with that of Mexico relations of peace and
good understanding. That functionary, however, notwithstanding these
representations and assurances, abruptly terminated his mission and
shortly afterwards left the country. Our envoy extraordinary and
minister plenipotentiary to Mexico was refused all official intercourse
with that Government, and, after remaining several months, by the
permission of his own Government he returned to the United States. Thus,
by the acts of Mexico, all diplomatic intercourse between the two
countries was suspended.

Since that time Mexico has until recently occupied an attitude of
hostility toward the United States--has been marshaling and organizing
armies, issuing proclamations, and avowing the intention to make war on
the United States, either by an open declaration or by invading Texas.
Both the Congress and convention of the people of Texas invited this
Government to send an army into that territory to protect and defend
them against the menaced attack. The moment the terms of annexation
offered by the United States were accepted by Texas the latter became so
far a part of our own country as to make it our duty to afford such
protection and defense. I therefore deemed it proper, as a precautionary
measure, to order a strong squadron to the coasts of Mexico and to
concentrate an efficient military force on the western frontier of
Texas. Our Army was ordered to take position in the country between the
Nueces and the Del Norte, and to repel any invasion of the Texan
territory which might be attempted by the Mexican forces. Our squadron
in the Gulf was ordered to cooperate with the Army. But though our Army
and Navy were placed in a position to defend our own and the rights of
Texas, they were ordered to commit no act of hostility against Mexico
