Lewis put down his gun.

On August 13, 1805, he had unexpectedly encountered three Shoshone females on a mountain path. The youngest woman ran away; an older woman and a girl remained. For days he had been trying to find people who could supply horses. The people before him, however, might reasonably take his armed party for enemies. Others whom he had seen at a distance had already fled. If this encounter ended the same way, making contact would become harder still.

He approached with beads, awls, small mirrors, and paint. Through signs, he asked the older woman to bring back the person who had run away. Once reunited, the three led his party onward. About two miles farther on, mounted men approached—roughly sixty, by Lewis's estimate. The women displayed their gifts and explained the strangers' conduct. Before any formal negotiation could begin, their intervention helped make it possible.

Then came an embrace from a chief, a pipe, and a welcome at the camp. Lewis later learned that the riders had initially feared an enemy encounter. He removed his shoes for the smoking ceremony, following local etiquette. The chief was Cameahwait. Contact had become possible, but easy communication had not. Drouillard knew signs that could convey the main elements of a message while leaving details uncertain. Lewis needed horses, a guide, and an answer to another question: was there a river beyond the mountains down which boats could travel?

Cameahwait drew waterways on the ground. He indicated tributaries, junctions, and mountains, explaining that the river downstream narrowed into a violent passage where rock walls also obstructed travel along the bank. He described another route to the north used by Indigenous travelers. Lewis still intended to have Clark examine the river himself. Yet even the questions the expedition could now ask depended on geographical knowledge provided by Shoshone people.

Horses stood near the camp, but their availability was not determined by the strangers' need. Lewis had seen animals bearing Spanish brands, as well as mules and Spanish equipment. These belonged to trading networks that long predated his arrival. Horses were also tied to obtaining food and defending communities. On August 14 he watched hunters pursue pronghorns by repeatedly bringing fresh mounts into the chase. After roughly two hours, they returned without a kill. His own hunters had been equally unsuccessful. A little flour and berries had to serve for a meal.

Cameahwait explained that enemies armed with guns threatened his people, who consequently spent much of their time in the mountains, depending on fish, roots, and berries. He wanted firearms that might help them defend themselves and reach buffalo country. This account survives through Lewis's understanding of translated speech or signs; it cannot stand for the whole of Shoshone history. It nevertheless shows that both parties had urgent needs, and that those needs were different.

When preparations began on August 15 to cross the mountains and meet Clark, some people refused to leave. A suspicion had spread that the strangers might be cooperating with enemies and leading them into an ambush. Cameahwait urged them repeatedly, without quickly gathering a party. Lewis invoked future trade and weapons supplies and challenged men to accompany him and test his account. Cameahwait decided to go. At first only a handful joined him; others followed later, including women.

Lewis described these changing decisions as caprice. The circumstances tell a more complicated story. People were being asked to take valuable horses away from their camp and cross a mountain with armed strangers whose trustworthiness remained unproved. Whether to supply horses, how many people should accompany them, and whether to proceed could not reasonably be decided by the expedition's timetable alone. Departure did not remove suspicion. It provided another opportunity to test a promise against an event.

On August 16 the uncertainty became acute again. When they approached the place where Lewis expected to meet the boats, there were no canoes. The mounted party slowed. Its leaders had to decide whether the expedition was merely delayed or whether the promised company did not exist. Some people had already turned back. Those remaining continued to take a risk.

Lewis handed Cameahwait his gun, explaining that it could defend him against any enemies ahead—or be used against Lewis himself if he had deceived them. His men also surrendered their weapons. Lewis then sent Drouillard to retrieve notes from a place where he had previously left a marker. The notes were his own earlier messages. He represented them instead as a fresh communication from Clark, reporting that the boats were advancing slowly below.

In his journal he acknowledged the deception and his discomfort with it. It helped temporarily without removing everyone's doubts; some complained that the strangers' accounts had changed. They finally agreed that Drouillard and a young Shoshone man would go downstream to investigate while Lewis and two companions remained. That night some slept near Lewis, while others concealed themselves in willow growth against a possible attack. Lewis recorded his own anxiety about the expedition and his difficulty sleeping.

This episode gives the next day's meeting its significance. Guns, gifts, and assurances about American power had not independently settled the question of trust. Would the investigators bring back confirmation? Would the boats and the other travelers appear? These were things that could actually be tested. While insisting on others' fidelity to promises, Lewis had misrepresented the origin of a note. That too belongs to the recorded expedition and cannot be erased because events ended favorably.

The following day, Clark arrived.

On August 17, he reached the meeting place with Charbonneau and Sacagawea. Sacagawea recognized Cameahwait as her brother. She also encountered a woman captured at the same time as herself who had subsequently escaped and returned home. Lewis recorded the reunion. For the expedition, it transformed the circumstances of interpretation and negotiation. For the reunited women, it was much more than an expedition arrangement. The journal records recognition but does not preserve their complete conversation or license an invented account of the intervening years.

At noon the canoes arrived, bringing the party and its baggage together again. They camped near the meeting of two rivers, unloaded their goods, and made a canopy from a large sail, with willow branches providing additional shelter. At the afternoon council, messages passed through Labiche, Charbonneau, and Sacagawea. What looked like one person's statement depended on several people's understanding before it reached its audience.

The captains explained their wish to reach the western ocean. They needed horses for their baggage and might also require a guide. They offered payment while invoking American governmental power, future commerce, and the supply of firearms. Cameahwait expressed willingness to help, but there were not enough horses present to move everything. He would need to return and encourage others to come. The captains distributed clothing, knives, tobacco, medals, and food. Sacagawea's family connection facilitated conversation; it did not put every horse at the captains' disposal. Transport, purchase, and compensation still had to be negotiated.

The captains divided their responsibilities. Clark would inspect the river and, if it proved navigable, look for timber and begin building canoes. Lewis would organize the rest of the people and baggage for the mountain crossing. Only if water travel failed would they need enough purchased horses for an extended overland journey. A horse temporarily hired to carry a load was not necessarily an animal its owner wished to sell. The expedition was investigating its choices while preparing for several possible answers.

During the wait, old equipment acquired new uses. Boards, paddles, and boxes supplied materials for pack saddles. Rawhide thongs could substitute where nails were scarce. Moccasins needed mending. Once the boats were left behind, every object previously supported by water had to find a place on an animal's back. A horse count meant little without considering baggage weight, saddles, terrain, and pasture.

On August 24 Lewis brought out axes made at Fort Mandan, together with knives, handkerchiefs, and paint. He purchased three horses and a mule. The mule cost more, requiring additional goods including clothing. Lewis valued it highly. The sellers nevertheless made clear that no more animals were available from them. Owned and hired animals together still could not take the whole load; Shoshone women carried part of the remaining baggage. The party finally started, with Lewis estimating that more pack animals would be needed for the mountain roads ahead.

Soon afterward, Wiser became too ill to proceed. Lewis rode back, gave him his own horse, and continued on foot. By the time he rejoined the others, the Shoshone carriers had unloaded their animals and turned them out to graze. The expedition stopped as well. They had traveled only about six miles. Turning a line of travel into an actual journey required attention to sick people and working animals; orders alone could not remove either burden.

The following day Charbonneau delivered news that Lewis thought should have reached him earlier. Cameahwait had sent for people on the other side of the mountains, intending that they join him and continue toward the Missouri country. Their departure could interrupt both the carriage of baggage and the purchase of horses. Lewis called the chiefs together, questioned them about their promises, and again used the prospect of future trading relations to exert pressure.

Cameahwait explained that he had acted because his people were hungry. The two parties' emergencies now stood side by side: the expedition feared losing its chance to proceed, while Shoshone families needed their chance to obtain food. According to Lewis, Cameahwait ultimately agreed to change the arrangements and sent a messenger asking his people to remain. Lewis issued tickets for horses used in transporting the baggage, redeemable in merchandise at their destination. He also shared meat brought by his hunters and gave another deer to women and children that evening.

On August 26 the party reached the camp west of the divide. Colter was there with a letter from Clark. Its conclusion removed the remaining prospect of a comparatively convenient route: the river would not support their intended canoe journey. They now needed animals they could take onward, rather than simply a hired service across the mountains. A fiddle played and the men danced, but Lewis admitted in his journal that he feared not obtaining enough horses. His anxiety is recorded; the thoughts of each prospective seller are not.

By August 28 Lewis had informed Clark that he had obtained twenty-two horses and asked him to return to help acquire more. On August 29 Clark exchanged his pistol, ammunition, powder, and a knife for a horse. The next day he traded a man's musket for another, replacing the man's weapon with his own. Clark recorded twenty-nine horses in all when they departed. Even that did not provide a separate mount for everyone. Some animals had sore backs; others were thin, young, or unaccustomed to carrying packs. Loads could not simply be piled onto them indiscriminately.

They purchased pack ropes, arranged saddles, and set off behind their guides. The same day, most of the Shoshone band began moving toward the Missouri country. Both parties had a journey they needed to make. The expedition's animals had not materialized as a miraculous rescue. They formed a pack train assembled through reunion, interpretation, uncertainty, hiring, shared food, and repeated bargaining. Their backs carried goods, and promises still awaiting fulfillment.
