E.R.S. Canby to E. R. S. Canby, U. S. Army, June 11, 1862

General E. R. S. CANBY, U. S. Army, Commanding U. S. Forces in New Mexico:

GENERAL: I had the honor to write you on the 3d ultimo from Fort Yuma, Cal., that I was on my way to Arizona, and desired to co-operate with you in driving the rebels from New Mexico. My messenger was unable to reach you via the Salinas Fork of the Gila on account of high water. I therefore dispatch another through Mexican territory, Iam ordered to recapture all the works in New Mexico which had been surrendered to rebels. This I shall proceed to do, starting from here as soon as the rains have filled the natural tanks, say early in July. What number of troops can find subsistence, say at twenty days notice, at Mesilla and Fort Bliss, in Texas? can start from here with sixty days’ supply for one battery of artillery, one regiment of infantry, and five companies of cavalry. With this force I desire to co-operate with you. This will enable me to hold this country besides. I have placed Arizona under martial law, and shall continue it so until th: civil officers come. I can bring more force if necessary. Let me know by the bearer your wishes, purposes, strength; the strength, position, and apparent purposes and condition of Sibley and his forces. l am, general,

your obedient servant,
