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.
Prior to his resignation, Meriwether Lewis had been assigned to Clark's unit as an ensign under Clark's command, and they came to respect each other. In 1803, Lewis recruited Clark, then age 33, to share command of the newly formed Corps of Discovery. Clark spent three years on the expedition to the Pacific Coast.
