The Fort Robinson tragedy (winter 1878-1879) refers to a series of events which occurred during the winter of 1878-1879 at Fort Robinson in northwestern Nebraska. After having been forced to relocate south to the Darlington Agency in the Southern Cheyenne Reservation, a band of Northern Cheyenne fled back north in September 1878 because of the terrible conditions. The US Army intercepted part of the Northern Cheyenne Exodus and took a band of nearly 150 Cheyenne to Fort Robinson in Nebraska.
