The 31st of August 1804 found the Corps of Discovery concluding its council with the Yankton Sioux at Calumet Bluff, near the mouth of the James River. Three journalists present — Captain William Clark, Sergeant Patrick Gass, and Private Joseph Whitehouse — left accounts of the day that diverge so sharply in length, focus, and register that they read almost as records of different events. Read together, they illustrate how the expedition’s hierarchy of literacy and responsibility shaped what was preserved.
Clark’s Ethnographic Ambition
Clark devotes the bulk of his entry to a sustained ethnographic portrait of the Yankton, beginning with what he calls “a curioes Society among this nation worthey of remark” — a warrior sodality bound by a vow “never to give back, let the danger or deficuelty be what it may.” He illustrates the vow with two anecdotes supplied through the interpreter Pierre Dorion: a winter river crossing in which the lead man, refusing to deviate from his course, drowned in an ice hole rather than go around it, and a battle with the “Crow de Curbo” in which eighteen of twenty-two society members were killed.
in war parties they always go forward, without Screening themselves behind trees or anything else, to this vow they Strictly adheer dureing their Lives
Clark then turns to diplomatic business: certificates issued to two attendants of the Great Chief, a commission and flag prepared for Dorion to broker peace among the Mahas, Poncas, Pawnees, Otoes, and Missouris, and instructions to escort chiefs to the President. He closes with a vocabulary and an enumeration of Sioux bands — “Che the ree or Bois ruley,” “Ho in de bor to,” “Me ma car jo” — beginning a tribal census he understood to be central to his charge from Jefferson. His observation that Sioux shares “a great many words… with the Mahas, Ponckais, Osarge, Kanzies” anticipates a comparative-linguistic conclusion: “Clearly proves to me those people had the Same Oregean.”
Gass’s Concrete Detail
Gass, writing for an audience that would eventually become the first published expedition journal, compresses the day into a few lines but preserves a sensory detail Clark omits entirely. He notes that the Yankton remained with the party all day and that “our old Frenchman” — Pierre Dorion — agreed to escort a chief to Washington. Then comes the image:
Some of them had round their necks strings of the white bear’s claws, some of the claws three inches long.
This is the kind of vivid material observation Gass habitually catches and the captains, preoccupied with structure and policy, often miss. The grizzly-claw necklaces would prove ethnographically significant; Gass records them without ceremony. His entry then moves directly into September 1, describing bluffs, hard wind, and an island encampment — the carpenter-sergeant’s customary terrain of weather, distance, and topography.
Whitehouse’s Compression
Whitehouse offers the briefest record of the three, and his entry is misdated or telescoped: he places the treaty under September 1 rather than August 31, writing only that
at that place Capt Lewis & Clark Held a treaty with the tribe of the Debough-bruley or the Burning wood.
His rendering “Debough-bruley” — a phonetic stab at Bois Brûlé, the French name for the Yankton band Clark lists first as “Che the ree or Bois ruley” — shows a private working from oral French rather than written sources. Whitehouse’s gloss, “the Burning wood,” translates the French literally and reflects camp talk filtered through an enlisted man’s ear.
Patterns of Divergence
The three entries demonstrate a consistent expedition pattern. Clark, charged with ethnography and diplomacy, produces a structured report combining anecdote, policy, vocabulary, and tribal taxonomy — material clearly destined for Jefferson. Gass, whose journal would be edited for publication by David McKeehan in 1807, favors the concrete and the visual, capturing the bear-claw necklaces no other narrator records. Whitehouse, working with limited literacy and likely catching up his journal after the fact, reduces the council to a single phonetically rendered sentence.
None of the three contradicts the others; rather, each preserves what his position and purpose made salient. Clark’s command of Dorion’s testimony, Gass’s eye for ornament, and Whitehouse’s confused French orthography together provide a fuller record of the Calumet Bluff council than any single journal could.
