The journals of November 18, 1804 offer a striking case study in how three members of the Corps of Discovery, encamped at the same place on the same day, produced strikingly different records of it. William Clark, John Ordway, and Patrick Gass each wrote from inside the same expedition, but their entries diverge so completely in subject matter that, read side by side, they reconstruct Fort Mandan as a layered settlement in which diplomacy, labor, and subsistence proceeded simultaneously and largely without overlap on the page.
Clark in the Council Lodge
Clark devotes his entire entry to a visit from Black Cat, principal chief of the Mandans, and to the diplomatic intelligence the visit produced. The chief, Clark notes, "made Great inquiries respecting our fashions" before turning to the more pressing matter of his nation’s exposed position between the Assiniboine and the Cree (Clark’s "Christonoes"). The passage is unusually candid about the limits of American influence:
a Council had been held the day before and it was thought advisable to put up with the resent insults of the Ossiniboins & Christonoes untill they were Convinced that what had been told thim by us, Mr. Evins had deceived them & we might also
The reference to "Mr. Evins"—the Welsh explorer John Evans, who had visited the Mandan villages in 1796–97 under Spanish auspices—shows the Mandans weighing the captains’ promises against prior disappointments. Clark’s diplomatic ear catches the analogy Black Cat draws between his own people and the Arikara: "the Assiniboins &c have the trade of those nations in their power and treat them badly as the Soux does the Ricarees." This is the day’s most consequential information, and it appears nowhere in the other journals.
Ordway at the Smokehouse
Ordway, by contrast, records the day from inside the construction project that would become Fort Mandan’s winter quarters. His entry is almost entirely technical, describing how the men finished a smokehouse by "bringing it up with Timber cross drawing in, So as to answer with chinks & dobbing & covering with earth & ashes for the covering without plank." The expedient earth-and-ash roof, he explains, was adopted because cutting plank for anything beyond the huts themselves would be "Troublesom." Ordway does mention a chief arriving at noon—almost certainly Black Cat, the figure who dominates Clark’s page—but he registers the visit only through its domestic outcome: "his Squaw brought a back load of corn in ears for us." What Clark frames as geopolitics, Ordway frames as provisioning.
Gass on the River and at the Hunt
Gass’s entry is the most disorienting of the three, because it does not appear to describe November 18 at Fort Mandan at all. He writes of "timber land on the south side, and hills and prairies on the north," of an island and sand bars, and of halting "on the south side of the river in order to jirk our meat" after killing eleven deer and a wolf. The passage reads as a travel day on the river rather than a stationary day at the wintering post. The discrepancy is a useful reminder that Gass’s published 1807 journal was edited by David McKeehan from Gass’s field notes, and dates in the printed text do not always align cleanly with the day-by-day record kept by Clark and Ordway. Gass also memorializes a detail neither captain repeats here: "Yesterday captain Lewis while hunting killed a bird not common in the states : it is like a magpie and is a bird of prey"—an early notice of what the expedition would come to recognize as a distinctive western species.
Patterns of Attention
The contrast in register is sharp. Clark, as co-commander, writes the diplomatic record; his prose carries the cadence of council speech and reported negotiation. Ordway, a sergeant tasked with daily oversight of the men, writes the labor record, attentive to materials and methods. Gass, also a sergeant and the expedition’s chief carpenter, writes—at least in his published form—a more generalized narrative of movement, weather, and game, with natural-history asides borrowed from Lewis. None of the three borrows language from the others on this date, suggesting that on November 18 the journalists were working independently rather than collating a shared text. The result is a day reconstructed only by triangulation: no single narrator saw the whole of it.
