The difficulty of procuring supplies of all kinds in this country makes it important that no greater force should be sent here than is absolutely necessary. No operations can be carried on with advantage from New Mexico against any part of the South, as all the supplies for such operations must be brought from the East, as no reliance be placed upon the resources of this country, Arizona, or Chihuahua.
I have the honor to be, very respectfully, sir, your obedient servant,
ED. R. S. CANBY,
Colonel Nineteenth Infantry, Commanding Department.

General LORENZO THOMAS,
Adjutant-General U. S. Army:
General Halleck telegraphs me he can give no orders in reference to the troops for New Mexico.
I reiterate my recommendation that not more than 500 infantry, 500 cavalry,and two batteries of light artillery be sent. All their subsistence will have to go from the Missouri River.
