This Day…

Outraged Cheyenne, Arapaho, and Sioux warriors launched a series of attacks all along the valley of the South Platte River in Colorado. The Indians strike at wagon trains, stage stations, and military outposts. The town of Julesburg, in northeast Colorado, is burned, and its white residents scalped in retaliation for the massacre at Sand Creek. Denver is threatened. Communications and supplies throughout the area are halted.
