The U.S. Army and the Lewis & Clark Expedition
Part 1: Introduction

As we commemorate its bicentennial, the famous Lewis and Clark Expedition evokes pride and awe in countless Americans who reflect upon its achievements. Its dynamism and sweep carried American explorers across the breadth of a vast continent for the first time. Its scientific agenda brought back invaluable information about flora, fauna, hydrology, and geography. Its benign intent established fruitful trade relations and encouraged peaceable commerce with Native Americans encountered en route. The Expedition was, all things considered, a magnificent example of our young nation�s potential for progress and creative good.

While most Americans have some inkling of the importance of the Lewis and Clark Expedition, relatively few recognize that it was an Army endeavor from beginning to end, officially characterized as the “Corps of Volunteers for North Western Discovery.” It is no accident that the new nation and its president, Thomas Jefferson, turned to the Army for this most important mission. Soldiers possessed the toughness, teamwork, discipline, and training appropriate to the rigors they would face. The Army had a nationwide organization even in that early era and thus the potential to provide requisite operational and logistical support. Perhaps most important, the Army was already in the habit of developing leaders of character and vision; Meriwether Lewis, William Clark, and the outstanding noncommissioned officers who served with them being cases in point.

This brochure was prepared in the U.S. Army Center of Military History by David W. Hogan, Jr., and Charles E. White. We truly hope you will enjoy this brief and engaging account of a stirring and significant event in our American military heritage.

The U.S. Army and the Lewis & Clark Expedition
Part 2: President Jefferson's Vision

Thomas Jefferson, author of the Declaration of Independence and third president of the United States, did much to help create the new nation. Perhaps his greatest contribution was his vision. Even before he became president, Jefferson dreamed of a republic that spread liberty and representative government from the Atlantic Ocean to the Pacific Ocean. As one of the leading scientific thinkers of his day, he was curious about the terrain, plant and animal life, and Indian tribes of the vast, unknown lands west of the Mississippi River. As a national leader, he was interested in the possibilities of agriculture and trade in those regions and suspicious of British, French, Spanish, and Russian designs on them.

On 18 January 1803, months before President Jefferson had acquired the region from France through the famous Louisiana Purchase, he sent a confidential letter to Congress, requesting money for an overland expedition to the Pacific Ocean. Hoping to find the Northwest Passage, Jefferson informed Congress that the explorers would establish friendly relations with the Indians of the Missouri River Valley, help the American fur trade expand into the area, and gather data on the region�s geography, inhabitants, flora, and fauna.

Meriwether Lewis by Charles Willson Peale, ca. 1807 (Independence National Historical Park)To conduct the expedition, Jefferson turned to the U.S. Army. Only the military possessed the organization and logistics, the toughness and training, and the discipline and teamwork necessary to handle the combination of rugged terrain, harsh climate, and potential hostility of the endeavor. The Army also embodied the American government�s authority in a way that civilians could not. Indeed, the Army provided Jefferson with a readily available, nationwide organization that could support the expedition � no small consideration in an era when few national institutions existed. Although the expedition lay outside the Army�s usual role of fighting wars, Jefferson firmly believed that in time of peace the Army�s mission went beyond defense to include building the nation. Finally, the man that Jefferson wanted to lead the expedition was an Army officer: his personal secretary, Capt. Meriwether Lewis.

A friend and neighbor of Jefferson�s, the 28-year-old Lewis had joined the Virginia militia to help quell the Whiskey Rebellion of 1794 and then had served for eight years as an infantry officer and paymaster in the Regular Army. In Lewis, Jefferson believed he had an individual who combined the necessary leadership ability and woodland skills with the potential to be an observer of natural phenomena.




Part 3: Preparations

Before Congress approved funds for the expedition, Lewis had already begun his preparations. From Jefferson he learned how to use the sextant and other measuring instruments. Together they studied Alexander MacKenzie�s account of his 1793 Canadian expedition to the Pacific coast and the maps in Jefferson�s collection. The president even had a special map made for Lewis that detailed North America from the Pacific coast to the Mississippi River Valley, with emphasis on the Missouri River. While the president drafted his instructions for the expedition, the captain worked on his planning and logistical preparations. In the evenings they discussed their concepts of the operation.

Leaving Washington in March, Lewis traveled to the Army�s arsenal at Harpers Ferry (at that time in Virginia), where he obtained arms, ammunition, and other basic supplies while supervising the construction of an experimental iron boat frame he had designed. Next, Captain Lewis went to Lancaster and Philadelphia, Pennsylvania, where Jefferson had arranged for some of the nation�s leading scientific minds to instruct Lewis in botany and natural history, medicine and anatomy, geology and fossils, and navigation by the stars. While in Philadelphia, Lewis purchased additional supplies, including a new condensed food, �portable soup.� He also arranged for theWilliam Clark by Charles Willson Peale, ca. 1810 (Independence National Historical Park) Army to provide transportation for his nearly four tons of supplies and equipment from Philadelphia to Pittsburgh. Lewis then set off for Washington for a final coordination meeting with President Jefferson.

When Lewis returned to Washington in mid-June, he was nearly two months behind his original schedule. He had hoped to be in St. Louis by 1 August; but after three intensive months of preparation, Lewis realized that the successful accomplishment of his mission would require more men and another officer. Now the president handed the captain his formal instructions. Foremost among Jefferson�s expectations was an all-water route to the Pacific. Lewis was told to explore and map the rivers carefully, to learn all he could about trade routes and traders of the region, and to study every Indian tribe along the way. Jefferson ordered Lewis to treat the Indians with dignity and respect and to invite their chiefs to come to Washington for a visit. Lastly, Captain Lewis was to describe the geography of the region and to bring back samples of plant and animal life. As they discussed the expedition, Jefferson acknowledged that it would require more men and another leader.

With Jefferson�s consent, Lewis wrote to his friend and former comrade, William Clark, offering him the assignment as co-commander. Both Lewis and Clark had served in the Legion of the United States under General Anthony Wayne a decade earlier. Clark had been an infantry company commander but had resigned his lieutenancy in 1796 to attend the business affairs of his older brother, General George Rogers Clark. In addition to approving the choice of William Clark, Jefferson ordered the War Department to give Lewis unlimited purchasing power for the expedition. Moreover, the president authorized the captain to recruit noncommissioned officers and men from any of the western army posts. On 4 July 1803, news arrived of the Louisiana Purchase, which resolved any international problems affecting the expedition. The next day Lewis set off for Pittsburgh.
