War Department, Washington, June 18, 1846.
At the request of the President I commend to your favorable consideration the bearer hereof, Colonel James W. Magoffin. Mr. M. is now and had been for some years a resident of Chihuahua and extensively engaged in trade in that and other settlements of Mexico. He is well acquainted with the people of Chihuahua, Santa Fe and intermediate country. He was introduced to the President by Col. Benton as a gentleman of intelligence and most respectable character. The President had had several interviews with him and is favorably impressed with his character, intelligence and disposition to the cause of the United States. His knowledge of the country and the people is such as induces the President to believe he may render important services to you in regard to your military movements in New Mexico. He will leave here for Santa Fe immediately and will probably overtake you before you arrive at that place. Considering his intelligence, his credit with the people and his business capacity it is believed he will give important information and make arrangements to furnish your troops with abundant supplies in New Mexico. Should you apprehend difficulties of this nature it is recommended to you to avail yourself in this respect and others of his services for which he will as a matter of course be entitled to a fair consideration.
Your Obt. serv.,
W. L. MARCY, Secretary of War.
Colonel S. W. Kearney.
