Deployed to posts from the Missouri River to the Pacific in 1848, the United States Army undertook an old mission on frontiers new to the United States: occupying the western territories; suppressing American Indian resistance; keeping the peace among feuding Indians, Hispanics, and Anglos; and consolidating United States sovereignty in the region.
