Bannock War

The Bannock War of 1878 was an armed conflict between the U.S. military and Bannock and Paiute warriors in Idaho and northeastern Oregon from June to August 1878. The Bannock totaled about 600 to 800 in 1870 because of other Shoshone peoples being included with Bannock numbers. They were led by Chief Buffalo Horn, who was killed in action on June 8, 1878. After his death, Chief Egan led the Bannocks. He and some of his warriors were killed in July by a Umatilla party that entered his camp in subterfuge.
