The first entry in the Lewis and Clark Expedition Journals state that the journey began in Pit â¦ tsburgh, PA on August 30, 1803. Lewis, who had been assigned by Jefferson sailed down the Ohio River with supplies towards St. Louis.
Congress allocated $2,500 for Lewis and Clark's expedition. Jefferson made Lewis another offer â to lead an expedition into the lands west of the Mississippi. Already eager to know more about these lands, Jeffersonâs interest in the area increased with purchase of the Louisiana Territory from France in 1803. Jefferson asked Lewis to gather information about the plants, animals, and peoples of the region.
