The Corps of Discovery

In 1803 the United States bought from France a vast territory west of the Mississippi, a transaction known as the Louisiana Purchase. The acquisition roughly doubled the size of the country, yet nobody in Washington knew what the land contained, where its rivers led or which peoples lived there. President Thomas Jefferson therefore asked Congress to pay for an expedition to explore the new territory, to look for a practical route to the Pacific and to record everything it encountered.

To lead the venture Jefferson chose his private secretary, Meriwether Lewis, a young army officer from Virginia. Lewis had no experience of commanding men in the field and little scientific training, so Jefferson arranged for him to spend some months in Philadelphia, learning astronomy, mapmaking, botany and medicine from the scholars of the day. Lewis then invited William Clark, who had been his commanding officer in the army, to share the leadership. The two agreed to treat each other as equals, and the party they assembled became known as the Corps of Discovery.

The expedition set out on 14 May 1804 from a camp near the mouth of the Missouri River and began to work its way upstream. Its largest vessel was a keelboat fifty-five feet long, with a sail and rows of oars, while two smaller boats carried extra stores. On the river the men lived under military discipline, standing watches at night and keeping their weapons ready, and each day they recorded the distance covered and the weather. Game was plentiful and the party made good progress while the river remained deep.

On the Great Plains the party met people of several Native nations, among them the Oto and the Sioux, and began to collect unfamiliar animals and plants. Prairie dogs were captured with difficulty, and one was eventually sent alive to Jefferson. Grizzly bears caused greater alarm: they were far larger than the black bears of the East, showed no fear of people and on several occasions chased the hunters. On 20 August 1804 the expedition suffered its only death when Sergeant Charles Floyd fell ill, probably with appendicitis, a condition that could not then be treated.

Winter forced the party to build a stockade, Fort Mandan, near the Mandan and Hidatsa villages in what is now North Dakota. There they hired a French Canadian trader, Toussaint Charbonneau, as an interpreter, although his wife Sacagawea proved far more useful. A Shoshone woman captured in childhood by a rival nation and taken far from her homeland, she could speak the language of the peoples ahead and acted as interpreter. In February 1805 she gave birth to a son, Jean Baptiste.

In April 1805 the expedition resumed its journey, and the river soon grew shallow and difficult, so that the men had to drag and pole the boats through rapids. At the Great Falls of the Missouri, where the river drops nearly 190 metres over about ten miles, the boats, supplies and instruments had to be carried overland around the falls. This portage of some eighteen miles took nearly a month in the summer heat and left the party short of food and strength.

By late summer they had reached the Rocky Mountains, and Lewis crossed the Lemhi Pass, where he met a band of Shoshone from whom the party hoped to buy horses. The meeting was tense until the Shoshone chief returned to the camp and recognised Sacagawea as his sister. That connection helped: the expedition obtained horses and a guide, and with their help crossed the mountains in bitter weather, at times eating tallow candles when food ran out.

Down the Clearwater and the Columbia rivers the party travelled through country where Native people had traded for generations, and in November 1805 it reached the Pacific Ocean. Rain fell almost without pause, and before long the explorers held a vote on where to build their winter quarters, in which every member took part, including Sacagawea and Clark's enslaved servant York. The majority chose a site south of the Columbia, where they built Fort Clatsop and spent a wet, comfortless winter.

The return journey began in March 1806. To cover more ground the party divided into smaller groups, which explored different rivers before meeting again on the Missouri. One group, led by Lewis, ran into trouble near the northern Rockies when Blackfeet warriors tried to steal the party's horses and shots were fired; two Blackfeet were killed. Reunited, the expedition travelled east and in September 1806 arrived at St Louis, where the townspeople came out to welcome it. They had been away for more than two years.

In one respect the mission had failed, since Jefferson had hoped for a continuous water route to the Pacific and no such route existed: the mountains could be crossed only on foot or on horseback. In other ways it had succeeded handsomely. The men had described hundreds of plants and animals unknown to American science, and had made maps of rivers and mountain ranges that later travellers relied on for decades. Their journals, edited and published in 1814, became a classic account of the American West. Lewis, appointed governor of the Louisiana Territory in 1807, died two years later of gunshot wounds whose cause has been debated ever since; Clark settled in St Louis and lived until 1838.
