Louisiana news and rumors
A Frankfort newspaper reports that Louisiana will be ceded to the United States while in Washington City, the National Intelligencer reports that the port of New Orleans has re-opened. Amongst these political changes, President Jefferson’s Western Expedition plans continue.

Fire Prairie
In present Missouri, an early morning storm awakens the men. After it passes, the enlisted men and engagés move the boats against a swift Missouri River crowded with snags. By the time they meet up with their hunters at Fire Prairie, the day is already hot and disagreeable. They camp near the present Jackson-Lafayette County line.

Portaging the first dugout
At the Great Falls of the Missouri, nearly all the enlisted men haul the first dugout canoe across the long portage route. The wagon needs frequent repairs, and after dark, they abandon the heavy boat and hike the remaining ½ mile to the White Bear Islands encampment. There, Lewis describes the western meadowlark.

Trade beads discovered
While waiting at Weippe Prairie for the Bitterroot Mountain snows to melt, Clark discovers some trade beads in one of his pockets, and Pvt. Whitehouse is sent to the Nez Perce villages to trade them for salmon. The hunters have a good day, and the cut on Pvt. Potts' leg becomes inflamed and painful.
Eastern Beginnings
10 January–30 August 1803
The Lewis and Clark Expedition ostensibly began in February 1801 when President Thomas Jefferson wrote a letter to Army commander General James Wilkinson requesting that Lieutenant Meriwether Lewis become the President’s personal secretary. Exploration of North America’s western half had long been a goal of the president, and now he had a young protégé who might lead such an expedition.
On 18 January 1803, Lewis hand-delivers to the U.S. Congress the President’s request to fund what would become known as the Lewis and Clark Expedition. The President works in Washington City and Monticello to craft instructions and line up the best talent to assist Lewis. In France, three diplomats negotiate with Napoleon Bonaparte to purchase the Louisiana Territory.
Meriwether receives training, supplies and equipment in Philadelphia and avails himself of armaments and specialized equipment—including a collapsable iron-framed boat—at the Schuylkill and Harpers Ferry arsenals. By July 1803, everything is at Fort Fayette in Pittsburgh. All Lewis needs is a large boat to carry everything down the Ohio. He also needs to know if William Clark will accept his invitation to join him.

Up the Missouri
14 May–20 July 1804
On 14 May 1804—after more than a year of preparation and travel—the boats leave Camp River Dubois and head up the Missouri River. At St. Charles, the two captains, Clark’s slave York, interpreter George Drouillard, eight or nine French engagés, 34 enlisted men, and Lewis’s dog Seaman depart in three boats: the barge and two large pirogues.
Everyone quickly learns of the struggles and hazards of moving up the Missouri with its many sawyers and sandbars. Despite the overloaded boats and several close calls, they safely pass many landmarks made familiar by earlier traders from St. Louis.
Crossing the present state of Missouri and then heading north along the Kansas-Missouri border, they pass the homelands of the Omaha, Kansa, Otoe, and Pawnee. On 21 July, they reach the mouth of the Platte where only a handful of traders had ever continued north towards the Knife River Villages.

Portaging the Falls
13 June–12 July 1805
On 12 June 1805, Lewis leaves Decision Point at the mouth of the Marias to find the Great Falls of the Missouri. He finds them “truly magnifficent and sublimely grand”.
After traveling separate routes from Decision Point, Clark and Lewis reunite at what would become known as Lower Portage Camp. Clark leaves to survey a portage route, and Lewis attends to Sacagawea whose condition has become “Somewhat dangerous”.
Wheels and trucks are built from cottonwood trees, and the dugouts are hauled two miles up Belt Creek. Lewis leads the first canoe overland to the White Bear Islands where he focuses on construction of the iron-framed boat.
Several trips are needed—as are several truck repairs—to get all the canoes and baggage to the upper portage camp. While site seeing during the last stage, Clark, Sacagawea, and Jean Baptiste are nearly swept away in a flash flood.
Celebrating the Fourth of July, they drink the last of whiskey. Then, due to a lack of pitch pine in the area, the cover of the iron-framed boat leaks too much water to be of practical use and is cached.
Clark moves a few miles up the river and his crew builds two more canoes so that they can continue up the Missouri.

Roads to the Buffalo
10 June–14 July 1806
With the acquisition of horses, Native Nations crossing the Rocky Mountains to hunt for bison became more common. Two of their trails are used by the captains—in separate groups—to return to the bison-rich plains.
After crossing the Bitterroot Mountains on what is known today as the Lolo Trail, the expedition divides forces at Travelers’ Rest. Lewis takes one group east and north up the Blackfoot River and then over Lewis and Clark Pass. They return to their old camp above the Great Falls of the Missouri to retrieve supplies and specimens cached there.
From Travelers’ Rest, Clark goes up the Bitterroot River and crosses the Continental Divide at present Gibbons Pass. They cross the Big Hole Valley and return to Fortunate Camp where they had cached tobacco, food, and most of the canoes.
At the Headwaters of the Missouri, Sgt. Ordway’s detachment paddles the canoes down the Missouri destined for the portage of the Great Falls. Clark’s group–along with all the horses—travel up the Gallatin River valley on their way to the Yellowstone River.

John Collins
Private
He had gotten off to a bad start, but apparently, the captains, or at least Clark, saw something in him that was worth saving. They would name Idaho’s Lolo Creek, Collins Creek.
François Labiche
Private
Labiche performed all the regular duties of an army private, but also performed well as a French and English interpreter. He would continue serving as an escort with Lewis for Chief Sheheke’s delegation to Washington City.
Hugh Hall
Private
As if to confirm the captains’ poor evaluation of the new arrivals from Fort Southwest Point, a scant nine days after his arrival, Hall was among a group of six or seven men who got drunk on New Year’s Eve.

Scientific Explorations
Their work in the emerging fields of botany, ethnography, geography, geology, and zoology are now considered classics of early American scientific literature.
Horse Travel
To cross the Rocky Mountains, the Lewis and Clark Expedition needed horses and the skills to manage them. Despite their seemingly constant struggle to find missing and stolen horses, as a kind of calvary unit, they left hoof prints on approximately 1,500 miles of western terrain.

Hunting and Fishing
Although hunting and fishing were often considered a ‘gentleman’s sport’ especially in Europe, hunting and fishing for Native Americans and Americans alike were a matter of survival. The success of the Lewis and Clark Expedition depended on the success of its hunters.

The Boats
Starting at Pittsburgh, traveling to the Pacific Ocean, and then returning to St. Louis, the Lewis and Clark Expedition traveled approximately 10,600 miles. Of that, 85%—over 9,000 miles—was by boat. To understand travel in the early 1800 American West is to understand the boats and challenges of river navigation.
Native American Nations
The Lewis and Clark Expedition benefited from the Indians’ knowledge and support. Maps, route information, food, horses, open-handed friendship—all gave the Corps of Discovery the edge that spelled the difference between success and failure.
Medicine on the Trail
From major crisis such as the death of Sgt. Floyd, Lewis’s gunshot wound, and the illness of Sacagawea to minor events such as sexually transmitted diseases, mosquito-born illnesses, and deep cuts, the medical aspects of the Lewis and Clark Expedition provide an interesting topic of study.
People
The success of the Lewis and Clark Expedition was due to its many members and the people they met, including politicians, Eastern gentleman scientists, traders, and the many people already living in the American west.
Other Topics
Other topics include music, holidays, High Potential Historic Sites, and an index of articles from We Proceeded On.
Language
From clichés and colorful sayings of the time to Native American languages, these pages feature the art of language.
The Trail
Starting with its genesis in Jefferson’s Monticello, Lewis’s training and preparations in Philadelphia, and the barge’s excursion down the Ohio River, the route they took, often called the Lewis and Clark Trail, crosses the continent weaving an epic tale of western exploration treasured by many today.
Trail Diplomacy
Lewis and Clark left behind among many Indians a legacy of nonviolent contact. Those who came later enjoyed that legacy and too often betrayed it.
Louisiana’s Purchase
The President’s representatives in Paris had bargained successfully with Napoleon’s bureaucrats not only to buy the port of New Orleans, then the keystone of the continent, but also to acquire, at three cents an acre, an area extending from the Mississippi River to . . . where? No one knew until Meriwether Lewis stood at the crest of the Rocky Mountains at a place known today as Lemhi Pass, on 12 August 1805.
Legacies
Legacy is a very slippery sort of term. If we could erase our myth concepts of Lewis and Clark … it might reawaken something really extraordinary in our national consciousness.
A Military Corps
Throughout the expedition the soldiers were expected to conform to the rules and routines of the frontier soldier of 1803.
The Fur Trade
Given President Jefferson’s directive to establish commerce, the captains worked extensively within a long-established network of North American fur trade. Part of their mission was to help establish the United States of America’s position within that industry.
The Arts
Because of the literate journalists, historians and visual artists can tell the Expedition’s story. When they celebrated with song and dance, we too can share in the experience.
