What is true about the expedition of Lewis and Clark?

The expedition of Lewis and Clark, also known as the Corps of Discovery, was commissioned by President Thomas Jefferson in 1804 to explore the newly acquired Louisiana Purchase. The expedition aimed to find a water route to the Pacific Ocean, establish relations with Native American tribes, and gather scientific data about the region's flora and fauna. After two years, Lewis and Clark successfully reached the Pacific Ocean and recorded valuable information about the uncharted territory.
