The West S01E04 - Death Runs Riot (1856-1868)

Civil war comes early to the West. In "Bleeding Kansas," abolitionists battle for free soil. In Utah, federal troops march against Mormon polygamy. And along the Rio Grande, oppressed Mexican Americans rebel. The war between North and South unleashes brute savagery in the West, and leaves behind an army prepared for total war against the native peoples of the plains.
