Ripples from La Prairie Voyageur Canoes: Chapter Five: Salish Country and a New Family, (1808

The mountains did not care that François Rivet had survived.

After the slaughter in the Bitterroot, the four living men of McClellan’s party were scattered fragments. Ammunition was almost gone. Without powder a man could neither feed himself nor keep the Blackfeet or Gros Ventres at a distance. Pride was a luxury none of them could afford. In the winter of 1808 Rivet made his way to the small North West Company outpost David Thompson had established at the falls of the Kootenay River and traded what little he still possessed for the means to stay alive.

Thompson was already becoming a legend among the men who worked the western slopes—the Stargazer, the mapmaker, the relentless traveler who measured the country with sextant and compass while others merely trapped it. Rivet was not a clerk or a partner. He was a free hunter in need of powder. The transaction was simple, pragmatic, and unmarked by sentiment. Yet it placed him inside the orbit of the North West Company at the exact moment the company was pushing hard to secure the Columbia drainage before the Americans could claim it.

By 1809 Rivet had moved deeper into Salish territory. The Flathead and Pend d’Oreille people called this country home—long grassy valleys, timbered ridges, rivers that ran clear and cold out of the high snow. The Salish had been traveling east across the mountains for generations to hunt buffalo on the plains, and they had their own complicated diplomacy with the Blackfeet, the Crow, and the western tribes. A French-Canadian trapper who spoke a little of the language, who did not cheat in trade, and who knew how to keep his head could find a place among them.

It was here that François Rivet formed the relationship that would define the rest of his life.

Therese was a young Salish widow. The records would later call her Therese Tête Platte—Therese of the Flatheads. She had been married before, to a man of a neighboring people, and she already had a small daughter. The girl’s name was Julia. Exact ages are uncertain; the country did not keep parish registers. What mattered was that Therese was willing to take a French husband according to the custom of the country, and that Rivet, at fifty-five, was ready to stop living entirely from one season to the next.

They made a family in the old way of the fur trade. No priest was present. No contract was signed in a notary’s office. The woman and the man simply began to live together, to share the lodge, the work, the children who would come. Their first son was born about 1809 and given his father’s name: François. Two more sons would follow in the next few years—Antoine and Joseph. Julia, the stepdaughter, remained part of the household, growing up bilingual and bicultural, a child of both the Salish world and the world of the free trappers.

In October 1809 David Thompson came into the same country to build a permanent post. He chose a site above the falls of the Clark Fork River, near present-day Thompson Falls, Montana, and began construction of what would be known as Flathead Post or Salish House. The roster of men present that autumn is a roll call of the early western trade: Finan McDonald, James McMillan, Michel Kinville, François Sans Facon, the Grégoire brothers, Pierre Grenon, Brucier, Bellaire, and others. Among them the records list François Rivet.

He was not a wintering partner or a senior clerk. He was a free man attached to the post—interpreter, hunter, occasional laborer, a link between the company and the Salish bands who came to trade. When Thompson’s men raised the stockade and the storehouses, Rivet was there. When the Salish arrived with their furs and their buffalo robes, he helped translate the long, careful negotiations. He understood both the value of a good post and the independence that still mattered to a man who had spent years answering to no bourgeois.

The years that followed settled into a rhythm. Rivet, Therese, the children, and the extended network of Salish kin moved with the seasons—trapping in the fall, wintering near the post or in sheltered camps, traveling east with the Salish buffalo hunters when the herds drew them across the mountains. The North West Company supplied goods on credit against future packs. Rivet supplied knowledge of the country and of the people. It was not wealth, but it was a living, and it was shared.

Manuel Lisa’s Missouri Fur Company men also drifted through the region in these years, probing west from the Yellowstone and the Three Forks. Rivet moved carefully among the competing interests. He had already seen what happened when free trappers and tribal war parties collided. He had no desire to die for another man’s flag or another man’s profit margin. When the competition between the North West Company and the upstart Pacific Fur Company sharpened after 1811, he kept to the middle ground as long as he could—selling packs where the price was best, interpreting when asked, always protecting the small household that now traveled with him.

By 1813 the family had become his true brigade. Therese managed the lodge and the children with the competence of a woman raised in a world where survival depended on skill. Young François, Antoine, and Joseph grew up hearing both French and Salish, learning to set a trapline and to read a horse’s temper. Julia was becoming a young woman. The Missouri River and the Bitterroot massacre were already stories told at night rather than living threats.

David Thompson himself would soon leave the Columbia for the last time, summoned east by the company’s endless internal politics. But the posts he had founded remained, and the network of free hunters and intermarried families that supported them remained as well. François Rivet, once a voyageur from L’Assomption and a temporary engagé of Lewis and Clark, was now something more difficult to define: a freeman of the western mountains, husband to a Salish woman, father of mixed-blood sons, and a quiet, durable thread in the fabric of the fur trade that stretched from the Missouri to the Columbia.

The country had taken most of McClellan’s party. It had nearly taken him. Instead it had given him a family and a place. In the years ahead both would be tested, but for the moment, in the lodge with Therese and the children, François Rivet had found a current strong enough to carry him forward.
