Battle of Milk Creek

When Major Thornburgh's column marched onto Ute lands in Colorado without permission — responding to an agent's call for troops to suppress a Ute leader — White River Ute warriors under Colorow and Jack ambushed the column at Milk Creek. Thornburgh was killed in the initial fighting. His command of 190 men was pinned down and besieged for six days until relief arrived. Simultaneously, Ute men killed Indian agent Nathan Meeker and nine employees at the agency, and took Meeker's wife and daughter hostage.

The Meeker Massacre and Milk Creek battle ended Ute control of western Colorado. Though the Ute had legitimate grievances — Meeker was forcibly plowing sacred land and attempting to transform their culture — the incident was used to justify removing the White River Ute from Colorado entirely. The battle was one of the last significant Native victories in the West.
