The entries of August 30, 1805, capture the Corps of Discovery at a hinge point: having bartered for a horse herd in the Lemhi Valley, the party set out under Shoshone guidance toward the formidable mountain crossing that would carry them to the Pacific drainage. Four narrators — Clark, Ordway, Whitehouse, and Gass — recorded the day, and their accounts reveal both the sergeants’ habit of close paraphrase and the captain’s distinct command-level concerns.
The Ordway-Whitehouse Parallel
The most striking feature of the day’s record is the near-identical structure of the Ordway and Whitehouse entries. Both men open with the horse tally, both relay the guide’s choice of routes in nearly the same terms, and both close with the ten-mile march and the camp on the river bottom. Ordway writes that the guide
could take us in 10 days to a large fork of the River which came in on the South Side where the River would be navigable or in about 15 days we could go to where the tide came up and Salt water.
Whitehouse renders the same intelligence with the figures reversed in order:
he could Show us a hilley rough roud [rout] over the mountains to the north of the River which would take us in 15 days to Salt water, or in 10 days to a large fork of the River, where it would be navagable.
The verbal overlap suggests either shared note-taking at the evening camp or one sergeant working from the other’s draft — a pattern scholars have documented elsewhere in the enlisted journals. Yet Whitehouse adds a meteorological opener (“a clear pleasant morning”) absent from Ordway, and his horse count differs: Whitehouse reports buying “3 more which makes 30 in all,” while Ordway records “8 more” to reach the same total of thirty. The discrepancy in newly purchased animals, against an identical sum, hints that one figure is a copying slip.
Clark’s Command Perspective
Clark’s entry stands apart in tone, register, and even arithmetic. Where the sergeants count thirty horses, Clark tallies twenty-nine, and he alone explains the shortfall and his remedy:
finding that we Could purchase no more horse than we had for our goods &c. (and those not a Sufficint number for each of our Party to have one which is our wish) I Gave my Fuzee to one of the men & Sold his musket for a horse which Completed us to 29 total horses
This is the kind of detail only the captain would record — a personal sacrifice of his own fowling piece to round out the herd. Clark also assesses the animals candidly: “Those horses are indifferent, maney Sore backs and others not acustomed to pack.” The grim parenthetical “(& Eate if necessary)” foreshadows the starving time in the Bitterroots that the sergeants, focused on the day’s logistics, do not anticipate. Clark also notes the guide’s three sons joining the party, a piece of social information Ordway and Whitehouse omit entirely.
Gass’s Silence and What Goes Unsaid
Gass’s entry for the day is remarkably brief — a single sentence noting that the corps came down within a mile of camp and stopped where there was good grass. His habitual terseness here contrasts sharply with the fuller sergeant entries and underscores how varied the journal-keeping discipline was across the noncommissioned officers.
What none of the four narrators remarks upon is the human dimension of the departure. As the corps marched downriver, “a part of these natives Set out with their horses to go over on the Missourie after the buffalow,” in Whitehouse’s phrasing, or as Ordway puts it, “apart of the natives went from this village over to the head of the Missourie after the buffalow.” Clark notes the same movement: “the greater Part of the Band Set out over to the waters of the Missouri.” None of the journalists records that this dispersal included Sacagawea’s own Lemhi Shoshone kin — the people from whom she had been separated as a child and to whom, by the evidence of the surviving record, she would not return. The editorial footnote in the published Ordway journal supplies what the narrators do not: the day marked a final parting.
The combined entries thus illustrate a recurring feature of the expedition’s documentary record: the sergeants converge on logistical facts, Clark adds the command-level reasoning behind those facts, and the human consequences of the day’s decisions often surface only by inference between the lines.
