Jefferson’s instructions dealt mainly with the geography and the Indians Lewis and Clark would meet on the way–a primary objective was ‘to explore… the most direct and practicable water communication across the continent, for the purpose of commerce.’ But Jefferson also hoped to assert the United States’ ownership of Louisiana, by use of military force if necessary.
