Answer 1

Background

Thomas Jefferson had long thought about such an expedition. While Minister to France from 1785-1789, Jefferson had heard of numerous plans to better explore the Pacific Northwest. In 1785, Jefferson learned that King Louis XVI of France planned to send a mission there, reportedly as a mere scientific expedition. Jefferson found that doubtful, and evidence provided by John Paul Jones confirmed these doubts. In either event, the mission was destroyed by bad weather after leaving Botany Bay in 1788. In 1786 John Ledyard, who had sailed with Captain James Cook to the Pacific Northwest, told Jefferson that he planned to walk across Siberia, ride a Russian fur-trade vessel to cross the ocean, and then walk all the way to the American capitol. Since Ledyard was an American, Jefferson hoped him success. Ledyard had made it as far as Siberia when Czarina Catherine the Great had him arrested and deported back to Poland. [1]

In a message to Congress, Jefferson wrote[2]

The river Missouri, and Indians inhabiting it, are not as well known as rendered desirable by their connection with the Mississippi, and consequently with us. ... An intelligent officer, with ten or twelve chosen men ... might explore the whole line, even to the Western Ocean ...

In a letter dated June 20, 1803, Jefferson wrote to Lewis[3]

The object of your mission is to explore the Missouri river, and such principal stream of it as by its course and communication with the waters of the Pacific ocean whether the Columbia, Oregon, Colorado or any other river may offer the most direct and practicable water communication across this continent for the purposes of commerce.

In 1803, the Louisiana Purchase sparked interest in expansion to the west coast. A few weeks after the purchase, President Jefferson, an advocate of western expansion, had the Congress appropriate $2,500, "to send intelligent officers with ten or twelve men, to explore even to the Western ocean". They were to study the Indian tribes, botany, geology, Western terrain and wildlife in the region, as well as evaluate the potential interference of British and French Canadian hunters and trappers who were already well established in the area. The expedition was not the first to cross North America but was roughly a decade after the expedition of Alexander MacKenzie, the first European to cross north of Mexico (almost) to the Pacific Ocean, in 1793.

Jefferson selected Captain Meriwether Lewis to lead the expedition, afterwards known as the Corps of Discovery; Lewis selected William Clark as his partner. Because of bureaucratic delays in the U.S. Army, Clark officially only held the rank of Second Lieutenant at the time, but Lewis concealed this from the men and shared the leadership of the expedition, always referring to Clark as "Captain"[1].

Clark made most of the preparations, by way of letters to Jefferson. He brought two large buckets and five smaller buckets of salt, a ton of dried pork, and medicines.

The group, initially consisting of 33 members, departed from Camp Dubois, near present day Hartford, Illinois, and began their historic journey on May 14, 1804. They soon met-up with Lewis in Saint Charles, Missouri, and the approximately forty men followed the Missouri River westward. Soon they passed La Charrette, the last white settlement on the Missouri River. The expedition followed the Missouri through what is now Kansas City, Missouri, and Omaha, Nebraska. On August 20, 1804, the Corps of Discovery suffered its only death when Sergeant Charles Floyd died, apparently from acute appendicitis. He was buried at Floyd's Bluff, near what is now Sioux City, Iowa. During the final week of August, Lewis and Clark had reached the edge of the Great Plains, a place abounding with elk, deer, buffalo, and beavers. They were also entering Sioux territory.

The first tribe of Sioux they met, the Yankton Sioux, were more peaceful than their neighbors further west along the Missouri River, the Teton Sioux, also known as the Lakota. The Yankton Sioux were disappointed by the gifts they received from Lewis and Clark— five medals—and gave the explorers a warning about the upriver Teton Sioux. The Teton Sioux received their gifts with ill-disguised hostility. One chief demanded a boat from Lewis and Clark as the price to be paid for passage through their territory. As the Indians became more dangerous, Lewis and Clark prepared to fight back. At the last moment before fighting began, the two sides fell back. The Americans quickly continued westward (upriver) until winter stopped them at the Mandan tribe's territory.

In the winter of 1804–05, the party built Fort Mandan, near present-day Washburn, North Dakota. There, the group found themselves trapped in their shelter without food when a violent rainstorm hit. The Shoshone/Hidatsa native woman Sacagawea and her husband, French Canadian Toussaint Charbonneau, joined the group, and saved the corp group's lives by bringing the starving men fish. Unfortunately, the men were not used to the fish, and became ill. However, the group recovered. Sacagawea enabled the group to talk to her Shoshone tribe from further west (she was the chief's sister), and to trade food for gold and jewelry. (As was common during those times, she was taken as a slave by the Hidatsa at a young age, and reunited with her brother on the journey.) She was able to aid them in translation, and she had some familiarity with the native tribes as they moved further west. The inclusion of a woman with a young baby (Sacagawea's son Jean Baptiste Charbonneau was born in the winter of 1804-05) helped to soften tribal relations since no war-party would include a woman and baby.

In April 1805, some members of the expedition were sent back home from Mandan in the 'return party'. Along with them went a report about what Lewis and Clark had discovered, 108 botanical specimens (including some living animals), 68 mineral specimens, and Clark's map of the United States. Other specimens were sent back to Jefferson periodically, including a prairie dog which Jefferson received alive in a box.

The expedition continued to follow the Missouri to its headwaters and over the Continental Divide at Lemhi Pass via horses. In canoes, they descended the mountains by the Clearwater River, the Snake River, and the Columbia River, past Celilo Falls and past what is now Portland, Oregon. At this point, Lewis spotted Mt. Hood, a mountain known to be very close to the ocean. On a big pine, Clark carved

"William Clark December 3rd 1805. By land from the U.States in 1804 & 1805"[4]

Clark had written in his journal, "Ocian [sic] in view! O! The Joy!". One journal entry is captioned "Cape Disappointment at the Enterance of the Columbia River into the Great South Sea or Pacific Ocean".[4] By that time the expedition faced its second bitter winter during the trip, so the group decided to vote on whether to camp on the north or south side of the Columbia River. The party agreed to camp on the south side of the river (modern Astoria, Oregon), building Fort Clatsop as their winter quarters. While wintering at the fort, the men prepared for the trip home by boiling salt from the ocean, hunting elk and other wildlife, and interacting with the native tribes. The 1805-06 winter was very rainy, and the men had a hard time finding suitable meat. Surprisingly, they never consumed much Pacific salmon.

The explorers started their journey home on March 23, 1806. On the way home, Lewis and Clark used four dugout canoes they bought from the Native Americans, plus one that they stole [2] in "retaliation" for a previous theft. Less than a month after leaving Fort Clatsop, they abandoned their canoes because portaging around all the falls proved too difficult.

On July 3, after crossing the Continental Divide, the Corps split into two teams so Lewis could explore the Marias River. Lewis' group of four met some Blackfeet Indians. Their meeting was cordial, but during the night, the Blackfeet tried to steal their weapons. In the struggle, two Indians were killed, the only native deaths attributable to the expedition. The group of four—Lewis, Drouillard, and the Field brothers—fled over 100 miles (160 km) in a day before they camped again. Clark, meanwhile, had entered Crow territory. The Crow tribe were known as horse thieves. At night, half of Clark's horses were gone, but not a single Crow was seen. Lewis and Clark stayed separated until they reached the confluence of the Yellowstone and Missouri Rivers on August 11. Clark's team had floated down the rivers in bull boats. While reuniting, one of Clark's hunters, Pierre Cruzatte, blind in one eye and nearsighted in the other, mistook Lewis for an elk and fired, injuring Lewis in the thigh. From there, the groups were reunited and able to quickly return home by the Missouri River. They reached St. Louis on September 23, 1806.

The Corps of Discovery returned with important information about the new United States territory and the people who lived in it, as well as its rivers and mountains, plants and animals. The expedition made a major contribution to mapping the North American continent.

Spanish reaction

On December 8, 1803, Lewis met with the Spanish lieutenant governor of Upper Louisiana, Colonel Carlos Dehault Delassus. Since France had never formally taken control of the territory, it was still governed by Spaniards. Delassus refused to let Lewis go up the Missouri until France formally took control of the territory, at which time France would formally give the territory to the United States. Lewis had intended to spend the winter in St. Louis since he needed to gain provisions for the trip and it was too late in the year to sensibly continue on the Missouri. Despite Lewis’ claims that the Expedition was solely a scientific one that would only travel the Missouri territory, Delassus wrote to his superiors that Lewis would undoubtedly go as far as the Pacific coast, citing that Lewis was far too competent for a lesser mission.[5]

While in Cincinnati, Ohio, Lewis had written to Jefferson about going to Santa Fe. This was done for political concerns; Lewis wanted "to give his party a winning issue" in the 1804 expedition. Jefferson was willing for Lewis to wait the winter in St. Louis rather than continue up the Missouri; Lewis could gain valuable information in St. Louis and draw from Army supplies rather than the Expedition’s. Jefferson knew how sensitive the Spanish were about their gold and silver mines and issued a direct order to Lewis not to go to Santa Fe. This also led Jefferson to question Lewis’ judgment. Jefferson’s concern was for naught; Lewis had already decided he had enough to do during the winter to get the Expedition ready for spring than to spend time traveling to Santa Fe.[6]

The fact that the Expedition would travel as much as it could on the Missouri River was done for political reasons. For one, it was imperative to stay out of Spanish territory. Jefferson had told Lewis not to go into Spanish territory. By staying in higher latitudes, the Expedition would avoid crossing into Spanish territory. [7]

Spain had ceded Louisiana to France under the condition that France would not give it to a third party. Spain gave France the territory because Napoleon had put his brother[citation needed] in charge of Spain, and Napoleon’s brother gave Napoleon Louisiana in exchanged for the kingdom of Etruria in Northern Italy. Spain wanted to keep the territory as an empty buffer between the U.S. and the many mineral mines in northern Mexico. After the start of the expedition, Spain sent at least four different missions to stop Lewis and Clark. During the Expedition’s stay in the Shoshone’s camps, the expedition was told they were ten days away from Spanish settlements. This warning helped Lewis and Clark stay away from the Spanish, but they never knew the Spanish had sent missions to stop them until after they returned from the journey.[8]

The Spanish sent these expeditions because of the intelligence they gained from an American traitor turned Spanish spy. General James Wilkinson was the commanding general of the United States Army. He was also in the employ of the Spanish government. In March 1804, he sent a message to Madrid telling the Spanish government that the purpose of the Expedition was to journey as far as the Pacific.[9].

Answer 2

Lewis & Clark explored the Louisianna Territory beginning in May of 1804. It lasted for 2 years 4 months & 10 days, & spanned over 8000 miles. The Louisianna Territory was purchased for $15 million ($27,267,622 after taxes only about 3 cents an acre)
They achieved peaceful cooperation with Indian tribes and generated American interest in the fur trade. This led to further exploration and commercial exploitation of the pacific northwest.
They also mapped a true route of the Upper Missouri, and destroyed dreams of a Northwest Passage.
Manifest Destiny (westward expansion for reasons of god, gold, & glory) later in the 1840's can be attributed to the Lewis & Clark Expedition
