Judge Watts indorsed my letter to General Canby, who sent a young officer, Lieutenant Hall, to Fort Fillmore with a copy of it, to investigate and report.

General Canby read Major Sibley’s letter of June 12th and mine of June 23d on June 29th, and Major Lynde having assumed command of Fort Fillmore he (Canby) wrote that officer as follows:

“Headquarters Department of New Mexico,

“Santa Fe, N. M., June 30, 1861.

“Maj. I. Lynde, Seventh Inf., Comdg. Fort Fillmore, N. M.: Sir—I had occasion on the 24th inst. to put you on your guard against the alleged complicity of Colonel Loring in the treasonable designs of the Texas authorities at Fort Bliss and El Paso. I now send a copy of one and extracts from another letter sent to me after the arrival of the mail yesterday, which fully confirm all the information I had previously received. Although Colonel Loring was still in the department, I have not hesitated, since this information was communicated to me, to exercise the command and to give any orders or to take any measures that I considered necessary to protect the honor or the interests of the Government.

“Sibley’s letter shows the Texas authorities at Fort Bliss and El Paso count upon Colonel Loring’s aid in furthering their plans and indicates the manner (by delaying his departure) in which this aid is to be rendered. Colonel Loring’s resignation was tendered on the 13th of last month, and has doubtless long since been accepted; but this is not material, for any failure to act at once, or any hesitancy in acting, may be in the highest degree disastrous. In this case, then, as in all similar cases which may occur, you will at once arrest the implicated parties and hold them securely until their guilt or innocence can be determined by the proper tribunals. No considerations of delicacy or of regard must be permitted to interfere when the honor of the country and the safety of your command are involved. I send these communications by Lieutenant Hall, Tenth Infantry. Very respectfully, sir, your obedient servant,

“Ed. R. S. Canby,

“Brevet Lieutenant-Colonel, U. S. Army, Comdg. Dept.”

I then returned to El Paso and settled my affairs preparatory to going to Santa Fe to take part with the Union people. There was then residing at El Paso a Col. Phil Herbert, who had been a member of Congress from California, but who, on account of bad conduct or misfortune, had left the State under a cloud. Having never seen anything in the conduct of this gentleman that was not honorable, generous and brave, it is not for me to speak of his supposed faults. He was an enthusiastic rebel, but my personal friend. When the stage coach was ready to start I took this man aside and confided to him where I was going, and why I was going. He approved of my determination and wished me personal success. I passed Fort Fillmore again en route to Santa Fe, July 1, 1861, and met Dr. Cooper McKee, the post surgeon, whom I knew well, and appealed to him to do something to prevent the surrender of the post. He appeared displeased at my remarks about his brother officers, and said that their sympathies or intentions were not his business, nor mine.

I met at the post another young army surgeon, Dr. Alden, who had lately arrived from Santa Fe. I found him as enthusiastic and as distrustful of the officers as myself. He told me he had thought of sending a private express to General Canby, advising him of the danger, but as I was going he would intrust it to me. He promised to meet me next day in Mesilla, and did so, but such was the feeling against Union men that this United States officer, almost under the guns of his post, did not dare to speak to me on the street, but beckoned me to an outhouse, where he privately handed me a letter to Lieutenant Anderson, Canby’s adjutant.
