US War Department - Report of Brigadier General O. O. Howard.

Abstract

"Rumors and Threats Against the John Day Band of Indians. The latter part of November, after the removal of the force near Pendleton, the usual fever that follows an Indian campaign filled the air with rumors of outbreaks of Indians, and some of the inhabitants of Eastern Oregon threatened to inaugurate further troubles by killing a band of Indians that had left the Indian reserve without formal permission, and were hovering around their old haunts not far from the mouth of the John Day's River."
