The news of the cession of the eastern bank of the Mississippi to the English brought consternation to the two or three thousand French people living in the settlements of the Kaskaskia, Illinois, and Wabash regions. The transfer of the western bank to Spain did not become known promptly, and for months the habitants supposed that by taking up their abode on the opposite side of the stream they would continue under their own flag. Many of them crossed the Mississippi to find new abodes even after it was announced that the land had passed to Spain.

From first to last these settlements on the Mississippi, the Wabash, and the Illinois had remained, in French hands, mere sprawling villages. The largest of them, Kaskaskia, may have contained in its most flourishing days two thousand people, many of them voyageurs, coureurs-de-bois, converted Indians, and transients of one sort or another. In 1765 there were not above seventy permanent families. Few of the towns, indeed, attained a population of more than two or three hundred. All French colonial enterprise had been based on the assumption that settlers would be few. The trader preferred it so, because settlements meant restrictions upon his traffic. The Jesuit was of the same mind, because such settlements broke up his mission field. The Government at Paris forbade the emigration of the one class of people that cared to emigrate, the Huguenots.

Though some of the settlements had picturesque sites and others drew distinction from their fortifications, in general they presented a drab appearance. There were usually two or three long, narrow streets, with no paving, and often knee-deep with mud. The houses were built on either side, at intervals sufficient to give space for yards and garden plots, each homestead being enclosed with a crude picket fence. Wood and thatch were the commonest building materials, although stone was sometimes used; and the houses were regularly one story high, with large vine-covered verandas. Land was abundant and cheap. Every enterprising settler had a plot for himself, and as a rule one large field, or more, was held for use in common. In these, the operations of ploughing, sowing, and reaping were carefully regulated by public ordinance. Occasionally a village drew some distinction from the proximity of a large, well-managed estate, such as that of the opulent M. Beauvais of Kaskaskia, in whose mill and brewery more than eighty slaves were employed.

Agriculture was carried on somewhat extensively, and it is recorded that, in the year 1746 alone, when there was a shortage of foodstuffs at New Orleans, the Illinois settlers were able to send thither "upward of eight hundred thousand weight of flour." Hunting and trading, however, continued to be the principal occupations; and the sugar, indigo, cotton, and other luxuries which the people were able to import directly from Europe were paid for mainly with consignments of furs, hides, tallow, and beeswax. Money was practically unknown in the settlements, so that domestic trade likewise took the form of simple barter. Periods of industry and prosperity alternated with periods of depression, and the easy-going habitants—"farmers, hunters, traders by turn, with a strong admixture of unprogressive Indian blood"—tended always to relapse into utter indolence.

Some of these French towns, however, were seats of culture; and none was wholly barren of diversions. Kaskaskia had a Jesuit college and likewise a monastery. Cahokia had a school for Indian youth. Fort Chartres, we are gravely told, was "the center of life and fashion in the West." If everyday existence was humdrum, the villagers had always the opportunity for voluble conversation "each from his own balcony"; and there were scores of Church festivals, not to mention birthdays, visits of travelers or neighbors, and homecomings of hunters and traders, which invited to festivity. Balls and dances and other merrymakings at which the whole village assembled supplied the wants of a people proverbially fond of amusement. Indeed, French civilization in the Mississippi and Illinois country was by no means without charm.

Kaskaskia, in the wonderfully fertile "American Bottom," maintained its existence, in spite of the cession to the English, as did also Vincennes farther east on the Wabash. Fort Chartres, a stout fortification whose walls were more than two feet thick, remained the seat of the principal garrison, and some traces of French occupancy survived on the Illinois. Cahokia was deserted, save for the splendid mission-farm of St. Sulpice, with its thirty slaves, its herd of cattle, and its mill, which the fathers before returning to France sold to a thrifty Frenchman not averse to becoming an English subject. A few posts were abandoned altogether. Some of the departing inhabitants went back to France; some followed the French commandant, Neyon de Villiers, down the river to New Orleans; many gathered up their possessions, even to the frames and clapboards of their houses, and took refuge in the new towns which sprang up on the western bank. One of these new settlements was Ste. Geneviève, strategically located near the lead mines from which the entire region had long drawn its supplies of shot. Another, which was destined to greater importance, was St. Louis, established as a trading post on the richly wooded bluffs opposite Cahokia by Pierre Laclède in 1764.

Associated with Laclède in his fur-trading operations at the new post was a lithe young man named Pierre Chouteau. In 1846—eighty-two years afterwards—Francis Parkman sat on the spacious veranda of Pierre Chouteau's country house near the city of St. Louis and heard from the lips of the venerable merchant stories of Pontiac, Saint-Ange, Croghan, and all the western worthies, red and white, of two full generations. "Not all the magic of a dream," the historian remarks, "nor the enchantments of an Arabian tale, could outmatch the waking realities which were to rise upon the vision of Pierre Chouteau. Where, in his youth, he had climbed the woody bluff, and looked abroad on prairies dotted with bison, he saw, with the dim eye of his old age, the land darkened for many a furlong with the clustered roofs of the western metropolis. For the silence of the wilderness, he heard the clang and turmoil of human labor, the din of congregated thousands; and where the great river rolls down through the forest, in lonely grandeur, he saw the waters lashed into foam beneath the prows of panting steamboats, flocking to the broad levee."

Pontiac's war long kept the English from taking actual possession of the western country. Meanwhile Saint-Ange, commanding the remnant of the French garrison at Fort Chartres, resisted as best he could the demands of the redskins for assistance against their common enemy and hoped daily for the appearance of an English force to relieve him of his difficult position. In the spring of 1764 an English officer, Major Loftus, with a body of troops lately employed in planting English authority in "East Florida" and "West Florida," set out from New Orleans to take possession of the up-river settlements. A few miles above the mouth of the Red, however, the boats were fired on, without warning, from both banks of the stream, and many of the men were killed or wounded. The expedition retreated down the river with all possible speed. This display of faintheartedness won the keen ridicule of the French, and the Governor, D'Abadie, with mock magnanimity, offered an escort of French soldiery to protect the party on its way back to Pensacola! Within a few months a second attempt was projected, but news of the bad temper of the Indians caused the leader, Captain Pittman, to turn back after reaching New Orleans.

Baffled in this direction, the new commander-in-chief, General Gage, resolved to accomplish the desired end by an expedition from Fort Pitt. Pontiac, however, was known to be still plotting vengeance at that time, and it seemed advisable to break the way for the proposed expedition by a special mission to placate the Indians. For this delicate task Sir William Johnson selected a trader of long experience and of good standing among the western tribes, George Croghan. Notwithstanding many mishaps, the plan was carried out. With two boats and a considerable party of soldiers and friendly Delawares, Croghan left Fort Pitt in May, 1765. As he descended the Ohio he carefully plotted the river's windings and wrote out an interesting description of the fauna and flora observed. All went well until he reached the mouth of the Wabash. There the party was set upon by a band of Kickapoos, who killed half a dozen of his men. Fluent apologies were at once offered. They had made the attack, they explained, only because the French had reported that the Indians with Croghan's band were Cherokees, the Kickapoos' most deadly enemies. Now that their mistake was apparent, the artful emissaries declared, their regret was indeed deep.
