CHAP. XI.] CORRESPONDENCE, ETC.-UNION.

WASHINGTON, D. C., July 3, 1861.

HonorableSIMON CAMERON, Secretary of War:

SIR: The President informed me last evening that you had completed your report, and advised me to call on you in reference to the troops about to be raised in New Mexico.

Advices from Governor Stanton and Judge Watts urge the importance of having three regiments, two of them to be mounted, and, in view of threatened aggressions in the northern as well as the southern portion of the Territory by the domestic foe, immediate action in the premises is deemed absolutely necessary.

I have seen Adjutant-General Thomas, and he concedes the propriety of having some cavalry, and is willing to recommend the addition of one regiment of mounted men to the two regiments already authorized; but it is almost unanimously agreed by officers of the Army and civilians who are acquainted with the character of the country, its wants, its population, and the existing emergency, that there should be at least three regiments, and that a majority of them should be cavalry. Every man will furnish his own horse for the mounted service, and thus a heavy preliminary expenditure will be avoided by the Government.

Major-General Fremont, and Colonel Blair, whom I had the honor of meeting at the President's, fully concur in the opinion that infantry troops are not well adapted to active service in the field in New Mexico, and the experience of those gentlemen in the country in question invests their opinion with the weight of high authority. The zeal I have manifested in this matter is prompted by no interest beyond that which every patriot should feel in his devotion to the integrity, the honor, and the flag of his country.

If you would most effectually strengthen the Government of the United States, physically and morally, in that recently conquered and imperfectly localized region of our country; if you would plant most deeply in the soil of New Mexico and in the hearts of her people the staff from which floats the "flag of the free," you must show the good faith of giving them ample protection, alike against the marauding savage and the rebellious domestic foe.

Earnestly hoping, my dear sir, that you may find it consistent with your sense of public duty and congenial with your well-known patriotism to give us the three regiments, two of them cavalry, and that in view of the exigencies you may immediately give the order to that effect, I have the honor to be, your obedient servant,

PERRY E. BROCCHUS.

HEADQUARTERS DEPARTMENT OF NEW MEXICO, Santa Fe, N. Mex., July 6, 1861.

His Excellency GOVERNOR OF COLORADO TERRITORY, Denver City, Colo.:

SIR: The increasing hostilities of the Indians in New Mexico will render it inexpedient to divert any portion of the volunteer force authorized for this department for the purpose of garrisoning Fort Garland. As this post is within the limits of Colorado Territory, I have the honor to request that you will cause two companies of infantry volunteer to be enrolled and sent to that post, to be mustered into the service of the United States at as early a period as possible.
