From the St. Louis Republican, Sept. 4.
Mormon Affairs.
Our correspondent writes us as follows, by the Ocean Wave: WARSAW, Sept. 1,1846.
The Anti-Mormon posse moved from Carthage toward Nauvoo on Sunday morning last, and encamped on the Fort Madison road, seven miles from Carthage, where they yet remain, and will not again take up their march until Thursday, awaiting in the meantime the reception of more reinforcements, and the receipt of some heavy artillery from St. Louis.
Persons who left the camp to-day, at 11 o'clock, say that the number is now about 800, a force which many consider entirely adequate to enter Nauvoo with; but the officers in command deem it best to march with such a number as will bear down all opposition, and at the same time accomplish their object with as small a loss of life as possible. The encampment, it is expected, will receive a large accession from the adjoining coun-ties between now and the resumption of their march, persons from several of them having visited the posse, and found that it was the determination to enter Nauvoo certain this time.
The Anti-Mormon camp is well supplied with provi-sions of all kinds, the citizens of the County freely con-tributing any thing in their possession to further the cause, without demanding or expecting any remunera-tion.
A quantity of powder, canister shot and muskets, in-tended for Nauvoo, came tip on Sunday night last, and while they were being put into the wagons to be con-veyed there, affidavit was made before a magistrate that they were intended to be used for unlawful purposes, and they were accordingly stopped. Last evening a de-tachment from the Anti-Mormon camp went up the river opposite Keokuk, and succeeded in getting posses-sion of the whole and bearing them to the camp. One hundred and fifty men were sent out from Nauvoo during the night to intercept the party and recapture the ammunition, but the expedition failed, the Anti-Mormons taking a different road.
This expedition is said by persons from Nauvoo, to have been under the immediate command of Captain Backenstos, of the United States Army ; if true, it cer-tainly presents a new feature in the history of the coun-try—officers of the regular army, heretofore being com-pelled to abstain from all interference in the domestic quarrels of the people, unless ordered to do so by the regular constituted authorities.
Regular sentries are placed by the parties on the prairie, between Nauvoo and the Anti-Mormon camp, and the pickets of each are alternately driven in during the night.
In addition to what is here stated, we learn from the Quincy Whig of Wendesday, that Col. John B. Chitten-den, of Adams Co. one of the signers of the Address which we published two or three days ago, had been ta-ken prisoner by the Mormons, and was confined at Nau-voo. They sent out word, it is said, that if he would come into the city they would negotiate a peace. He did so go in, and when there they seized him as a pris-oner.
On the evening of the 31st, a numerous meeting of the citizens of Quincy was held to take measures to reduce the Mormons to obedience, and effect the immediate liberation of Col. Chittenden.
The meeting voted
"1st. That in cases of emergency delays are danger-ous ; 2d. That in order to carry out the resolves of the meeting, to assist in executing the laws of the State, it is essentially necessary that aid should be given those who are engaged in the legal discharge of their dutyin Hancock County, opposed by a mob in Nauvoo—we therefore re-commend that as many mounted Volunteers as can be mustered at the Court House, in Quincy, on Wednesday morning, the 2d inst., armed for the occasion, ready for marching to the scene of action, with four days of pro-vision. In the mean time, in the Committee will visit Carthage and meet the Volunteers at Ursa at 11 o'clock on Wednesday and report as circumstances may re-quire."
