The Lewis and Clark "Corps of Discovery", as it eventually came to be called, was conceived by Thomas Jefferson. He was dedicated to exploration of the vast territory west of the Mississippi River and learning about the Native Americans who resided there. He wanted to find a water route to the Pacific Ocean and map the topography. Also, he expected the Corps to catalog the flora and fauna they encountered. On the Monticello web site read about Thomas Jefferson's part in funding and planning the Corp's work.
MERIWETHER LEWIS AND WILLIAM CLARK
President Jefferson chose his secretary Meriwether Lewis as the ideal candidate to captain the Corps. Lewis then chose his Co-Captain, William Clark. They had served in the military together and were an ideal team. Between them, they possessed the skills needed to face the challenges of their incredible journey.
Monsieur Charbonneau is not noted for his popularity with the rest of the Corps or his abilities as a member of the team...it appears that the only contribution of real value he provided was the interpreting services of his wife, Sacajawea. This description of Charbonneau makes it clear he was considered a sort of "necessary evil".
There are many questions surrounding Sacajawea's story that have been controversial. One is the correct spelling/pronunciation of her name and another question is at what age and where did she die? My search for accurate information about these questions and others about Sacajawea led me to the descendants of her tribe of origin, the Lemhi Shoshoni. I found a site from the Sacajawea Interprative, Cultural, & Educational Center. Tim Woodward interviewed members of Sacajawea's birth tribe. The story of the kidnapping and slavery of Sacajawea and her marriage to Charbonneau make difficult reading. Her life as a member of the Corps of Discovery is but a small piece of her complex history. From the time she was kidnapped, Sacajawea's life was determined by people who were not interested in her happiness but in taking advantage of her talents. Sacajawea probably died due to an illness that may have resulted from the birth of her second child, a daughter named Lissette.
JEAN-BAPTISTE CHARBONNEAU (POMPEY)
Sacajawea gave birth to Jean-Baptiste during the first winter of the expedition when they were camped at Fort Mandan in North Dakota. William Clark was very fond of the toddler nicknamed "Pomp" or "Pompey". The landmark Pompey's Pillar was named after Pompey. After the expedition he was provided for by Clark, but never adopted by him. Jean-Baptiste spent time as an adult in Europe but eventually returned to the United States to take up a mountain man lifestyle similar to his father's. The man, who had traveled as a child on one of the greatest explorations of all time, died and is buried in Oregon.
York was William Clark's slave and belonged to him from the time both were children. His contributions to the success of the Corps were as valuable as any of the other members. In recent years, letters William Clark wrote to his brother reveal that he did not feel York's "services" with the Corps had any value. He didn't care that York wished to live close to his wife and refused to grant him his freedom. Clark told his brother that if York didn't improve his attitude he was going to loan him to a harsh master. The final years of York's life are detailed by the National Park Service. You can learn how York's position in the 1800's is typical of the complexities of the slave/owner relationship.
SERGEANT CHARLES FLOYD
Sgt. Floyd holds the dubious honor of being the only member of the Corps of Discovery to perish on the journey. This unhappy event took place soon after the Corps embarked on their Missouri River voyage. Flying at Sgt. Floyd's monument is a replica of the 15 star and 15 stripe flag he would have defended for the military. Visit his Sioux City memorial to learn what ended Sgt. Floyd's trek.
Seaman was a Newfoundland dog and a valued member of the Corps of Discovery. He was purchased by Meriwether Lewis for $20 (about $400 in 1806), perhaps because he had webbed feet and much of the trip was intended to take place by pirogue. Seaman caught small game, entertained the expedition members and provided excellent service at guard duty. There are many theories about what became of Seaman. This version of Seaman's fate is intriguing...and it appears to be based on some historical evidence. Here is a great photo of a sculpture including Seaman which is located in Fort Clatsop National Park--he is paying very close attention to the flounder rather than his guard duty.
WHO WERE THE OTHER GUYS
The rest of the Corps included volunteer members of the U.S. Army and a handful of civilians. They were chosen for the skills they could contribute in carrying out the goals of the expedition and for keeping all members alive and safe.
