First Contact in the Mountains
Cameahwait — chief of a band of Lemhi Shoshone encountered west of the Continental Divide in August 1805 — became, in the span of two weeks, one of the most consequential Native figures the Corps of Discovery would meet. Without his cooperation, the expedition would have been stranded at the headwaters of the Missouri without horses to cross the Bitterroots. The journal record of him is concentrated almost entirely in Meriwether Lewis’s entries between August 13 and August 26, 1805, supplemented by an editorial summary of the August 17 reunion with Sacagawea.
Lewis first encountered Cameahwait’s band on August 13, 1805, after a long and tense pursuit of any Shoshone willing to make contact. The chief and his warriors received Lewis’s small advance party in their camp west of Lemhi Pass. Over the next several days Lewis, joined eventually by Clark and the rest of the party, negotiated for horses, information about the country ahead, and assistance crossing back over the divide to retrieve the expedition’s cached baggage.
August 14: Learning the Country
Lewis spent August 14 in Cameahwait’s camp gathering geographical intelligence. He observed Shoshone hunting techniques in detail — the cooperative antelope hunts in which men "seperate and scatter themselves to the distance of five or six miles in different directions arround them" — and noted the precariousness of the band’s food supply. The Shoshone had little to share, and Lewis’s men were reduced to flour, parched meal, and berries furnished by their hosts.
August 15: A Reluctant March East
On August 15, after a breakfast of flour-and-berry pudding shared with Cameahwait, Lewis tried to persuade the chief and his men to ride east with him over the divide to meet Clark’s party. The Shoshone hesitated. Lewis recorded the chief’s candor about the rumor circulating in his camp:
the Chief addressed them several times before they would move they seemed very reluctant to accompany me. I at length asked the reason and he told me that some foolish persons among them had suggested the idea that we were in league with the Pahk[ees]…
The fear was that Lewis was leading them into ambush by their enemies. That Cameahwait moved his people anyway — on the strength of Lewis’s word and the gifts already exchanged — is a measure of the personal trust the chief was willing to extend.
August 17: The Reunion at Camp Fortunate
The single most dramatic moment in Cameahwait’s appearance in the record was not written by Lewis or Clark themselves in the entries provided here, but is preserved in the editorial summary for August 17, 1805. When Sacagawea was brought forward to interpret negotiations, she recognized the chief as her own brother:
She instantly jumped up, and ran and embraced him, throwing over him her blanket, and weeping profusely.
The reunion transformed the negotiation. Lewis named the site "Camp Fortunate" in recognition of the extraordinary luck. Cameahwait now had a personal as well as diplomatic motive to help the expedition, and the horse trade that followed was made possible largely through this bond.
August 19–22: Negotiating at Camp Fortunate
The journal entries from August 19 through 22 show Lewis methodically preparing to leave the navigable Missouri behind. He built a cache to hide baggage from the Shoshone (Lewis, Aug. 20), constructed pack saddles, and continued to feed Cameahwait’s hungry people from the expedition’s dwindling stores. The chief’s band was visibly underfed; Lewis repeatedly notes that the Shoshone "appeared to depend on us for food."
An incident on August 22 illustrated the strain. Drouillard surprised an Indian camp in the Cove and, leaving his rifle unattended, was nearly robbed before recovering most of his property. Lewis treated the episode as a near-miss rather than a breach, recovering "a considerable quantity of Indian plunder" without escalation — a sign of the careful diplomacy that Cameahwait’s friendship made possible.
August 23–24: Delays and Horse Trades
On August 23, Lewis wished to depart but yielded to the chief’s request to wait for another arriving party of Shoshone:
I wished to have set out this morning but the cheef requested that I would wait untill another party of his nation arrived which he expected today, to this I consented from necessity…
The delay paid off. On August 24, when the new party arrived with spare horses, Lewis traded battle axes (made at Fort Mandan), knives, handkerchiefs, and paint for three horses and a mule. Cameahwait’s mediation made these transactions possible. By the end of the day Lewis had nine horses, a mule, and two hired horses — twelve animals — enough to begin the move.
August 25: A Crisis of Loyalty
The most revealing moment in Cameahwait’s portrait came on August 25, when Charbonneau casually mentioned that the chief had sent runners ahead to summon all the Shoshone east of the divide — meaning Cameahwait intended to leave Lewis stranded on the mountain in order to lead his people on a buffalo hunt down the Missouri. Lewis was furious — at Charbonneau for the delayed report, but also alarmed at what the chief’s defection would mean. He confronted Cameahwait directly. The chief, by Lewis’s account, acknowledged the plan and, when reproached, agreed to countermand his messengers and stay with the expedition until the baggage was carried over. The episode shows Cameahwait balancing two desperate obligations — his promise to Lewis against the hunger of his own people, who needed the autumn buffalo hunt to survive the winter.
August 26: Over the Divide
On August 26, the combined party crossed back to the extreme source of the Missouri. Lewis distributed corn — "a pint of corn to be given each Indian who was engaged in transporting our baggage" — and the column moved over the pass that Cameahwait’s people had used for generations. With this crossing, Cameahwait largely passes out of the journal record provided here. His horses, his geographic knowledge, and his willingness to risk his band’s safety on Lewis’s word had carried the expedition over its single greatest logistical obstacle.
Character in the Record
The Cameahwait of the journals is patient, hungry, generous within the limits of his band’s poverty, and torn between competing duties. Lewis describes him sharing a flour pudding and pronouncing it "the best thing he had taisted for a long time" — a small detail that conveys both the chief’s courtesy and the genuine scarcity in which his people lived. He is candid about his band’s fears (the Pahkee rumor), willing to delay personal plans at Lewis’s request, and ultimately willing to be talked out of abandoning the expedition. He is also, as the August 25 episode shows, a chief whose first responsibility is to his own people’s survival, not to American strangers.
Limits of the Record
Almost everything we know of Cameahwait from these entries comes filtered through Lewis. We have no journal entry by Clark in this sample treating Cameahwait directly, and Sacagawea’s perspective on her brother — surely the richest in the camp — is unrecorded except through the brief editorial note of their reunion. Of Cameahwait’s life before or after August 1805 the journals here say nothing. What survives is a two-week portrait of a chief who held the expedition’s fate in his hands and chose, repeatedly, to help.
