The consul of the United States at the City of Mexico was therefore instructed by the Secretary of State on the 15th of September, 1845, to make the inquiry of the Mexican Government.  The inquiry was made, and on the 15th of October, 1845, the minister of foreign affairs of the Mexican Government, in a note addressed to our consul, gave a favorable response, requesting at the same time that our naval force might be withdrawn from Vera Cruz while negotiations should be pending.  Upon the receipt of this note our naval force was promptly withdrawn from Vera Cruz.  A minister was immediately appointed, and departed to Mexico.  Everything bore a promising aspect for a speedy and peaceful adjustment of all our difficulties.  At the date of my annual message to Congress in December last no doubt was entertained but that he would be received by the Mexican Government, and the hope was cherished that all cause of misunderstanding between the two countries would be speedily removed.  In the confident hope that such would be the result of his mission, I informed Congress that I forbore at that time to “recommend such ulterior measures of redress for the wrongs and injuries we had so long borne as it would have been proper to make had no such negotiation been instituted.”  To my surprise and regret the Mexican Government, though solemnly pledged to do so, upon the arrival of our minister in Mexico refused to receive and accredit him.  When he reached Vera Cruz, on the 30th of November, 1845, he found that the aspect of affairs had undergone an unhappy change.  The Government of General Herrera, who was at that time President of the Republic, was tottering to its fall.  General Paredes, a military leader, had manifested his determination to overthrow the Government of Herrera by a military revolution, and one of the principal means which he employed to effect his purpose and render the Government of Herrera odious to the army and people of Mexico was by loudly condemning its determination to receive a minister of peace from the United States, alleging that it was the intention of Herrera, by a treaty with the United States, to dismember the territory of Mexico by ceding away the department of Texas.  The Government of Herrera is believed to have been well disposed to a pacific adjustment of existing difficulties, but probably alarmed for its own security, and in order to ward off the danger of the revolution led by Paredes, violated its solemn agreement and refused to receive or accredit our minister; and this although informed that he had been invested with full power to adjust all questions in dispute between the two Governments.  Among the frivolous pretexts for this refusal, the principal one was that our minister had not gone upon a special mission confined to the question of Texas alone, leaving all the outrages upon our flag and our citizens unredressed.  The Mexican Government well knew that both our national honor and the protection due to our citizens imperatively required that the
