“Lewis and Clark left St. Louis filled with apprehension about encounters with hostile Indians. But what emerged over nearly two and half years of western travel was an atmosphere of friendship and mutual trust between men and women who shared a common frontier life.”
Meriwether Lewis was to answer a long list of questions about the American Indians they encountered. They were to inform each nation that there was new “American Father” who would protect them and trade with them. They were to establish peace among warring tribes and change established trade relationships with European companies. They would often rely on the Native Nations to guide them and to simply survive. They would need to employ all the diplomatic skills they possessed.
