Ripples from La Prairie Voyageur Canoes: Chapter Two: The Missouri Beckons, (Late 1790s

The Saint Lawrence had been a wide brown highway with steeples and seigneuries along its banks. The Missouri was something else entirely.

François Rivet first felt the difference in the water itself. Where the Canadian rivers ran cold and clear from the northern forests, the Missouri came down out of the western plains thick with silt, the color of weak coffee with too much milk. It carried whole trees in its spring flood, rolled sandbars from one side of the channel to the other overnight, and possessed a current that could exhaust a fresh brigade in a single upstream day. The old voyageurs who had come down from Michilimackinac or the Illinois country spoke of it with a mixture of respect and quiet profanity. They called it the Big Muddy, or simply la rivière, as if no further name were required.

By the late 1790s François had left the familiar parishes behind. The exact year he crossed from the Great Lakes drainage into the Mississippi system is not written in any surviving contract, but the pattern was common enough. A man finished an engagement, heard that the Spanish officials in St. Louis were still granting licenses, or that the independent traders were paying better for experienced paddlers, and simply kept going south and west. He was in his forties now—old enough to be called le vieux by the younger engages, still strong enough to pull a paddle from dawn until the light failed. The restlessness that the farms of L’Assomption could not quiet had found a larger stage.

He fell in with the mixed community of French, French-Canadian, and Métis traders who worked the lower and middle Missouri. These were not the disciplined brigades of the North West Company. They were smaller parties—six men, ten men, sometimes only three or four—moving in pirogues or battered canoes, carrying kegs of powder, bales of cloth, guns, and the endless small items that could be traded for packs of buffalo robes or the occasional beaver. They wintered in rough cabins or in the earth lodges of the river tribes. They learned the languages in fragments: a little Kansa, a little Omaha, the Sioux dialects that changed as one moved upstream, the more formal speech of the Arikara and the Mandan.

François learned the country the way he had once learned the Ottawa and the French rivers—by the feel of the current against the paddle blade, by the shape of the bluffs, by the smell of the prairie when the wind came from the west. He watched the Kansa villages with their neat earth lodges and extensive cornfields. He saw the Omaha and the Ponca, the Yankton Sioux who came to the river to trade, and farther up the more formidable Teton bands whose horsemen could appear on the ridges without warning. He listened to the older traders talk of the Arikara towns that controlled the channel like toll gates, and of the Mandan and Hidatsa villages still farther north where the river bent in great loops and the winters were said to freeze the thoughts inside a man’s head.

The work was harder than the Canadian trade and often more dangerous. There were no fixed depots stocked by the company. A party lived on what it carried, what it hunted, and what it could persuade the tribes to sell. Relations shifted with the season and the memory of the last quarrel. A man who smiled and traded fairly one year might find the same village closed against him the next because some other party had cheated or killed. François adapted. He had always been practical. He spoke softly, watched carefully, and kept his weapons close without making a show of them.

In 1802 the St. Louis merchant Régis Loisel mounted a more ambitious venture. Loisel was one of the sharper traders operating under Spanish license, a man with connections and credit. He pushed farther upriver than most, aiming for the powerful Teton Lakota bands who controlled much of the trade on the middle Missouri. Among the engages who went with him was a man the records call simply “La Riviere.”

The identification is not written in copperplate certainty, yet the pieces fit too cleanly to ignore. François Rivet was in the country. He was experienced. He was French-Canadian. And the incident that followed has the feel of a story that would cling to a man for the rest of his life.

They were deep in Teton territory when the trouble came. The Bois Brulé band—hard men on good horses—surrounded the trading party. Accusations flew: short measure, bad powder, some earlier slight that no one in Loisel’s group could remember. Voices rose. Guns were half-lifted. In the center of the shouting, one of the warriors drew a bead on the engagé called La Riviere and came within a breath of firing. Whether it was Loisel’s quick talking, a timely gift, or simple chance that stayed the trigger, the records do not say. The moment passed. The trade, such as it was, continued in a climate of cold watchfulness. When the party finally turned downstream in the spring of 1803, they carried fewer packs than they had hoped for and a sharper understanding of how quickly the Missouri could turn.

François Rivet came back to St. Louis with the taste of that near-death still in his mouth. The town itself was changing. In the months he had been upstream, word had arrived that the vast western territory claimed by Spain had been ceded back to France, and that France in turn was selling it to the young United States. The Louisiana Purchase was not yet a settled fact in every tavern, but the air was full of rumor. American officers were said to be coming. A great expedition was whispered about—an expedition that would go up the Missouri farther than any trader had yet gone and perhaps reach the western ocean.

St. Louis in 1803 was still a French town in speech and habit. The streets near the river were dusty or muddy according to the weather. Stone and log houses stood behind high walls. The riverfront smelled of fish, woodsmoke, tobacco, and the sweet rot of the occasional dead animal washed up on the bank. Merchants argued in French and Spanish and the rough English of the American newcomers. Free men and engages and enslaved laborers moved along the levee. Above it all the church of St. Louis still rang its bells as if the world had not changed.

François found lodgings and waited. He was nearly fifty. His hair was going gray at the temples; the lines around his eyes were cut deep by sun and wind. He had no wife waiting in any parish, no farm to reclaim. What he possessed was a reputation among the Missouri traders as a man who could handle a boat, keep his head, and come back alive. That reputation, and the restlessness that had carried him this far, were enough.

In the taverns and warehouses he listened to the talk of the American captains who would soon arrive—Meriwether Lewis and William Clark. They would need boatmen. They would need men who already knew the lower river, the moods of the tribes, the difference between a sandbar that would hold and one that would swallow a keelboat. They would need, whether they fully understood it yet or not, the skills that three generations of Rivet voyageurs had perfected on other waters.

François Rivet sat in the spring sunlight on the St. Louis waterfront, felt the pull of the Missouri still running in his blood, and understood that the next current was already forming. The near-death among the Bois Brulé had not cured him of the river. If anything, it had clarified the terms. The Missouri did not forgive carelessness, but it still offered something the settled parishes never could: the chance to disappear into distance and return—if one returned at all—with a story no one else could tell.

He would be ready when the Americans came looking for men who knew how to pull an oar against the current.
