The reunion of the Corps of Discovery on August 12, 1806, marks one of the expedition’s most narratively rich moments, in part because all four surviving journalists set pen to paper that day. Their entries cover the same sequence of events — the morning meeting with two American trappers, the rejoining of Colter and Collins, and the long-anticipated reunion with Clark’s detachment — yet each narrator emphasizes different elements, producing a layered record of a single day.
The Trappers on the River
All four narrators record the encounter with Joseph Dickson and Forest Hancock, the first Americans the Corps had met since leaving Fort Mandan in the spring of 1805. Lewis, writing as commander, frames the meeting administratively: he provides a navigational briefing and a material gift, noting he "gave them a short discription of the Missouri, a list of distances to the most conspicuous streams and remarkable places on the river above and pointed out to them the places where the beaver most abounded. I also gave them a file and a couple of pounds of powder with some lead."
Ordway, by contrast, supplies the trappers’ biography and ambition with a level of detail Lewis omits. He records their names, their Illinois origin, their two years on the river, and their plans:
they are determined to Stay up this river and go to the head where the beaver is pleanty and trap and hunt untill they make a fortune before they return, they had 20 odd good traps and tools for building canoes
Ordway also notes that "Mr Dixon concludes to go back to the Mandans in hopes to git a frenchman or Some body to go with him" — a logistical detail absent from Lewis’s account. Gass, characteristically terse, compresses the encounter to a single sentence about ammunition and directions, then moves on. Clark does not mention the trappers at all in this entry, his attention fully absorbed by Lewis’s wound.
The Wound and Its Tellers
The accidental shooting of Lewis by Pierre Cruzatte the previous day produces the sharpest divergence among the four accounts. Lewis himself buries the matter in a single clause — "my wounds felt very stiff and soar this morning but gave me no considerable pain" — and explicitly hands narrative duty to his co-captain: "as wrighting in my present situation is extreemly painfull to me I shall desist untill I recover and leave to my frind Capt. C. the continuation of our journal."
Clark accepts that charge immediately. His entry contains the fullest forensic account of the accident, including the trajectory of the ball and an exoneration of Cruzatte:
the ball had passed through the fleshey part of his left thy below the hip bone and cut the cheek of the right buttock for 3 inches in length and the debth of the ball… This Crusat is near Sighted and has the use of but one eye, he is an attentive industerous man and one whome we both have placed the greatest Confidence in dureing the whole rout.
Gass and Ordway, lacking the captains’ intimacy with the injury, treat it briefly. Gass offers a measured reassurance — "Capt. Lewis, and his wound is not dangerous" — while Ordway omits the wound entirely from his August 12 entry, choosing instead to celebrate the reunion: "we fired the blunderbusses and Small arms being rejoiced to meet all together again."
Reconstructing Clark’s Absent Months
Because Clark’s August 12 entry pivots immediately to summarize Lewis’s overland route from Travelers’ Rest, it falls to Gass and Ordway to reconstruct what Clark’s own party had done since the separation. Both sergeants offer retrospective summaries of the Yellowstone passage, and the parallels suggest one may have informed the other — or both drew on the same fresh oral debrief from Clark’s men.
Gass writes that Clark "travelled three days up Gallatin’s river towards the south, when they crossed a ridge and came upon the waters of the Jaune or Yellow-stone river," and that after Sergeant Pryor’s horse detachment was robbed, "the party were obliged to descend the river in skin canoes." Ordway gives the same sequence with more precise mileages: "nearly to its head which was about 30 miles… crossd over a low ridge 10 miles then come on the head waters of the roshjone," and specifies that Pryor set out with twenty-five horses, of which the Indians took all on the second night. Ordway alone records the total Yellowstone distance — "836 miles" — and the buffalo so thick they impeded navigation.
The register differences are instructive: Gass writes for eventual print publication and smooths the geography into readable prose; Ordway preserves the working sergeant’s interest in numbers, traps, and game tallies ("6 buffaloe 13 deer 5 Elk & 31 beaver"); Lewis, even wounded, slips back into natural history with a botanical description of a "singular Cherry"; and Clark, the day’s designated scribe, attends to his injured friend. Together the four entries form a more complete record of the reunion than any single journal could provide.
