Ook op een 23e september (1806), Lewis en Clark komen thuis van hun driejarige aardse ontdekkingsreis.
Lewis And Clark Expedition summary: The United States purchased Louisiana from France in 1803. The huge part of the land west of the Mississippi River was completely unknown to Americans and needed to be examined first before it could be settled. President Jefferson decided to send an exploratory expedition west so he appointed his own private secretary, Meriwether Lewis as a Commander in charge of the expedition and finding appropriate guides for it. Lewis invited his former superior officer from the Army, William Clark, to be his Co-commander.
