How the West Was Won (1962) on Netflix

The story of how, over several generations, families opened up the Western U.S. to settlement. Zebulong Prescott, his wife Rebecca and daughters Eve and Lilith make the perilous journey, first down the newly built Erie Canal. Along the way they meet hunter and trapper Linus Rawlings, a genuine mountain man and catches Eve's eye in particular. They go their separate ways but Linus helps them out again when river bandits try to rob the Prescotts of their earthly possessions. A subsequent tragedy on the river however brings Eve and Linus together. Eve's sister Lilith decides to leave as soon as possible but ends up meeting her man, Cleve Van Valen and they make their way to the West Coast where they make their fortune. Eve and Linus' son Zeb fights in the Civil War and stays in the army afterward. He is assigned to protect the railroad, currently under construction. He sees the fear Indians have of the encroachment of white men onto their lands and the destruction of the buffalo. He makes a name for himself as a lawman and eventually agrees to take over his aunt Lilith's ranch, but not before having to take on one last fight.
