Brigham long ere this had decided that his people must flee away to some remote region where collisions and conflicts should cease; and his sturdy will and untiring energy were exerted to carry out this decision. He selected California as the future residence of the Saints. At that time it formed a part of Mexico, and consequently was beyond the control of the detested Stars and Stripes and the uncomfortable people who had thrice expelled them from their dwelling-places. Brigham made known his purpose to the people and declared that they would move as rapidly as possible across Iowa to the Missouri River into the Indian country near Council Bluffs that season. This new exodus began in February, 1846, the bleakest and coldest month in the year in that section of the country. An indescribable pageant of ox-carts and mule-teams, loaded with women, children, and all sorts of furniture passed out from Nauvoo to the miry tracks of the prairies; but the spirits of all, except the sick and helpless, were unbroken. Here Brigham Young proved himself the general as well as commander. He directed every detail of the evacuation. He arranged that the population should not move in a solid body, so as to disturb by their numbers the inhabitants of the sparsely-populated country they would traverse, but they should move in sections carefully selected, following each other at short intervals of time. But in spite of this preparation there was a report that some of the Mormons intended to remain, and, in violation of the promises of the State, the Illinoisans called out the militia, and _drove the defenceless residents who remained from their homes at the point of the bayonet_, after bombarding the city for three days and nights. This was in the month of September, 1846. Thus ended Mormon history in Illinois; thus ended the history of Nauvoo, which is as wonderful as that of any city ever built. Its rise, progress, and destruction occupied only seven years, but many of its mysteries have yet to be told.
