From the St. Louis Union of the 22d.
Later from Nauvoo.
The New-Haven got down last evening, bringing a number of families from Nauvoo. All was quiet at that place on Saturday, when they left. But very few of the proscribed citizens remained, and they were pre-paring to leave as speedily as possible. Among the pas-sengers on the New Haven were Mr. Robbing and family, and Mrs. Carlisle Smith, the latter a highly intelligent lady, the widow of a brother of the murdered Joseph and Hyrum Smith. They intend making this City their residence. Mr. Robbins was keeper of the Temple, and incurred, as such, the especial odium of the "old citi-zens." At Keokuk, as the party descended, he barely escaped assassination.
From a gentleman who was in Nauvoo when the Un-ties entered, we learn that their number was sixteen hundred and twenty-five, and that their train of baggage wagons numbered over one hundred. It is supposed that they suffered severely, during the skirmishing of the three days. Some persons who were lying sick in a house near the outposts, aver that they saw more than twenty wounded men borne from the field, after the fight of Friday.
The few Mormons yet remaining, as well as many that have left, are in quite a wretched condition. They have barely the means of sustaining existence. The philan-thropise John Wood had left Quincy with a quantity of provisions for their relief. One of the stipulations of the treaty, (if so the terms of capitulations might be called,) was, that the Mormons should receive their arms, as they crossed the river. This had been complied with.
The St. Louis Republican of the 23d says: Every boat from Keokuk is crowded with Mormons, who have left Nauvoo in compliance with the stipulations of the late treaty. Some of them are in a destitute condition, and demand he sympathy of the public. We learn that many persons have embarked on steamboats going up the river, probably with a view of attaching them-selves to the church at Voree, in Wisconsin.
The Warsaw Correspondent of the same paper says, under date of September 20th :
On Wednesday, the 16th inst. through the mediation of the Quincy Committee of One Hundred, articles of capitulation were signed by the beligerent parties. They had been given by Major Brockman as his ultimatum, from which lie would not recede, and were finally ac-cepted by the Mormons—Clifford being their Comman-der-in-chief. These articles were to this effect:
1st. That the posse might enter the City on to- morrow, (the 17th,) at 3 o'clock. 2d. The arms of the Mormons to be given into the hands of the Quincy Committee, and by them re-delivered, after the Mormons had left the City. 3d. The posse pledged protection to the persons and property of the Mormons 4th. The Mormon popu-lation to immediately leave the State.
At 3 o'clock, on Thursday, the posse marched into the City and encamped in the South end of town. Before they had arrived, however, nearly all the Mormons and Jacks, agreeably to the stipulations, had left, by crossing the river into Iowa.
