Sand Creek massacre
A number of Cheyenne north of Denver on the South Platte Trail were killed by soldiers of the First Colorado Cavalry in the spring of 1864. Julesburg was attacked on January 7, 1865 by about 1,000 Cheyenne and Sioux men in retribution for the Sand Creek massacre (November 29, 1864). At Fort Sedgwick, several Native Americans and some soldiers were killed, and there was so much food looted from Julesburg that it took three days to remove it to their village at Cherry Creek or Sand Creek. After that, three groups of Native Americans, the Arapaho, Cheyenne, and Sioux, engaged in an attack on stage stations and ranches along the South Platte Trail over a period of six days. They killed more people than were killed at the Sand Creek Massacre, burned building, tore down telegraph lines, and looted horses, 2000 cattle, and wagon trains, one of which had 22 wagons. There were further attacks in 1865 between Julesburg and Fort Morgan, including burning down the town of Julesburg in February. The town was rebuilt.
