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.

In mid-December 1803, construction of winter quarters begins. In accordance with the wishes of the Spanish Governor, Lewis could work in St. Louis and the soldiers could build a garrison in Illinois across from the mouth of the Missouri. The Wood river cantonment is known today as Camp River Dubois.

Winter at Fort Mandan

26 October 1804–6 April 1805

On 2 November 1804 below the Knife River Villages, work begins on the expedition’s winter fortification. The men’s quarters, storage rooms, and the 16-foot pickets, are designed for defense against hostile Indians, especially the Sioux, who would be quite troublesome, although they never attacked the fort directly. “This place we have named Fort Mandan,” Lewis recorded, “in honour of our Neighbours”—their kind and congenial Mandan Indians. Here they celebrate their second Christmas and New Year’s Day.

    Alexander Willard

    Private

    Including a court martial, charging grizzlies, and a mile-long swim down the Missouri River, Willard’s adventures are well-documented in the journals. He survived them all, crossing the Missouri a final time on his way to California, at age 74.

    John Shields

    Private

    During the damp winter at Fort Clatsop and throughout 1806, the journals speak more and more often about Shields’ life-sustaining work as gunsmith. Certainly the guns had seen hard use.

    John Ordway

    Sergeant

    Ordway’s journal is the only one carries an entry for every one of the trek’s 863 days. Just after the expedition ended, Ordway had purchased the land warrants issued to Jean-Baptiste Lepage and William Werner.

Olin D. Wheeler’s major contribution to the enhancement of Lewis and Clark studies was his inclusion of numerous illustrations. The Trail of Lewis and Clark, 1804-1904 contained photographic reproductions of 8 portraits; 8 photos of important artifacts, such as Pvt. Shannon’s “housewife,” or pocket sewing kit; 15 maps; 24 manuscript documents, including copies of several pages from the original journal pages provided him by Reuben Thwaites; and 24 copies of paintings by prominent American and Euro-American artists. For his travels, see Wheeler’s “Trail of Lewis and Clark”.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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 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.
