In March 1874, the U.S. Government authorized a military camp at the Red Cloud Indian Agency on the White River, home to about 13,000 Indians and one of the most troublesome spots on the Plains. The camp was named Camp Robinson for Lt. Levi H. Robinson, who had been killed by Indians the previous month, was moved to this site in May, and was officially designated Fort Robinson in January 1878. Fort Robinson played an important role in the Indian wars from 1876 to 1890. Crazy Horse surrendered here on May 6, 1877, and was mortally wounded that September while resisting imprisonment. In January 1879, it was the scene of a major battle resulting from the Cheyenne Outbreak led by Chief Dull Knife. In the 20th Century, Fort Robinson became the world's largest military remount depot, and during the second World War it was the site of a K-9 corps training center and a German prisoner-of-war camp. Its deactivation after the war ended more than 70 years of service as Nebraska's outpost on the plains.
