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 unless she declared war or was herself the aggressor by striking the first blow.  The result has been that Mexico has made no aggressive movement, and our military and naval commanders have executed their orders with such discretion that the peace of the two Republics has not been disturbed.  Texas had declared her independence and maintained it by her arms for more than nine years.  She has had an organized government in successful operation during that period.  Her separate existence as an independent state had been recognized by the United States and the principal powers of Europe.  Treaties of commerce and navigation had been concluded with her by different nations, and it had become manifest to the whole world that any further attempt on the part of Mexico to conquer her or overthrow her Government would be vain.  Even Mexico herself had become satisfied of this fact, and whilst the question of annexation was pending before the people of Texas during the past summer the Government of Mexico, by a formal act, agreed to recognize the independence of Texas on condition that she would not annex herself to any other power.  The agreement to acknowledge the independence of Texas, whether with or without this condition, is conclusive against Mexico.  The independence of Texas is a fact conceded by Mexico herself, and she had no right or authority to prescribe restrictions as to the form of government which Texas might afterwards choose to assume.  But though Mexico can not complain of the United States on account of the annexation of Texas, it is to be regretted that serious causes of misunderstanding between the two countries continue to exist, growing out of unredressed injuries inflicted by the Mexican authorities and people on the persons
