The New York Herald publishes the following offi-cial despatches received by the War Department from the Peace Commissioners at Salt Lake City and from General Johnston, commanding the forces in Utah. The substance of these documents has already been printed, but they will be found interesting:-
Letter from, the Peace Commissioners to the Secre-tary of War.
GREAT SALT LAKE CITY,
Utah Territory, June 12, 1858.
Dear Sir-We have the honor to report that we reached this city on the 7th inst. We lost no time in placing ourselves in communication with the chief men of the Mormon people. After the fullest and freest conference with them, we are pleased to state that we have settled the unfortunate difficulties ex-isting between the government of the United States and the people of Utah. We are informed by the people and chief men of the Territory that they will cheerfully yield obedience to the Constitution and laws of the United States. They cheerfully consent that the civil officers of the Territory shall enter upon the discharge of their respective duties. They will make no resistance to the army of the United States in its march to the valley of Salt Lake or else-where. We have their assurance that no resistance will be made to the officers, civil or military, of the United States, in the exercise of their various func-tions in the Territory of Utah.
The people have abandoned all the settlements north of this, and all the families have left the city, only about fifteen hundred persons remaining here to take charge of the property, and to burn it if the difficulties had not been settled. The people from this city and north of it have gone south to Provo, fifty miles south of this, and to points beyond. We will visit Provo and the settlements south in a day or two, and see and confer with the people, and in-form them that the difficulties have been settled, and thus induce them to return to their homes.
We have written Gen. Johnston by the messenger that will bear this, informing him of what had been done, and that he could march his army to the val-ley whenever he desired to do so. We intend to re-main and visit the people and converse with them until Gen. Johnston's army arrives. We think it important that we remain until the army is located in the valley. We have but a moment to write, as the express will start in a few moments. We will in a few days forward a detailed report.
We have the honor to be, very respectfully, your obedient servants,
L. W. POWELL, Commissioners
BEN. MCCULLOCII, to Utah.
Hon. John B. Floyd, Sec. of War, Washington, D. C.
Despatch of Gen. Johnston to the War Department.
HEADQUARTERS, DEPARTMENT OF UTAH,
CAMP ON BEAR RIVER, U. T., June 16, 1858.
MAJOR-I have the honor to report that the march of the army of Utah commenced on the 13th inst. The advance, composed of the Second dragoons, com-manded by Col. Cook; the Volunteer Battalion, com-manded by Lieut.-Colonel Bee; and Phelps's Light Battery, arrived here on the 14th inst.; the Fifth infantry, Col. Waite commanding, and Reno's Bat-tery, on the 15th, accompanied by a part of the sup-ply train. Today the Tenth infantry, commanded by Col. Alexander, and a battalion composed of one company of cavalry, one company of Mounted Rifles, three companies of the Third, two companies of the Sixth, and one company of the Seventh infantry, commanded by Col. Loring, will arrive with the re-mainder of the supply train.
The river rises during the night, but can be forded in the afternoon. The crossing, therefore, of the dragoons, volunteers, and train was not effected till yesterday evening. An old bridge above the ford was sufficiently repaired to enable Captain Phelps to pass his pieces and caissons over by hand. This evening Captain Reno's battery will be crossed in the same way. The Fifth infantry and trains will cross this evening, and if there is time afterwards, the Tenth infantry, Col. Loring's battalion and trains, will also cross, and the march will be resumed to-morrow in the order directed by my order of this date herewith. The march to the valley will be made in five days.
On the day of my arrival at this place I received a communication from the United States Commission-ers, the Hon. L. W. Powell and Major Ben. McCul-loch, of which the enclosed is a copy. I have the honor to transmit a copy of my reply, and also a few remarks which it was thought I should address to the people to allay an unfounded apprehension prevailing among them.
Captain Newton, of the Engineer corps, was de-tached yesterday, with an escort of an officer and thirty men, and the most experienced guide of the mountains, James Bridger, to examine thoroughly the country from this point to the head of Muddy creek, which flows into Bear river. I believe the ele-vated table land between this and the western end of the Cache valley can be ascended by easy gradations, and that the opposite side can be descended into Cache valley without difficulty. If a good road should be found practicable, as I expect, I would re-spectfully suggest that the commander of the forces here may be authorized to order its construction im-mediately. The only communication between impor-tant districts should not long be allowed to continue through long and difficult canons easily obstructed.
The health of the troops continues excellent.
With great respect, your obedient servant,
A. S. JOHNSTON,
Colonel Second Cavalry and Brevet Brigadier Gen-eral United States Army Commanding.
To Major Irvin McDowell, Assistant Adjutant General, Headquarters of the Army, West Point, New York.
The communication from the Commissioners re-ferred to, advises Gen. Johnston of their success, and suggests that a proclamation be issued to the Mor-mons by him, informing them that the army would not trespass upon the rights or property of peaceable citizens, which, they think, would greatly allay the existing anxiety and fear of the people, and cause those who have abandoned their homes to return.
The following proclamation was accordingly is-sued:-
Governor Johnston's Proclamation to the People of Utah.
The Commissioners of the United States, deputed by the President to urge upon the people of this ter-ritory the necessity of obedience to the Constitution and laws, as enjoined by his proclamation, have this day informed me that there will be no obstruction to the administration and execution of the laws of the federal government, nor any opposition on the part of the people of this territory to the military force of the government in the execution of their orders. I therefore feel it incumbent on me, and have great satisfaction in doing so, to assure those citizens of the territory who, I learn, apprehend from the army ill treatment, that no person whatever will be in any-wise interfered with or molested in his person or rights, or in the peaceful pursuit of his avocation; and should protection be needed, that they will find the army always faithful to the obligations of duty, as ready now to assist and protect them as it was to oppose them while it was believed they were resisting the laws of their government. A. S. JOHNSTON, Colonel Second Cavalry and Brev. Brig. Gen. Com.
The army would continue its march on the 17th of June, and was expected to reach the valley in five days.
