From the record
“The Camas Meadows Battle Sites, also known as Camas Meadows Camp and Battle Sites, are two sites important to the Battle of Camas Creek, fought August 20, 1877 between members of the Nez Perce tribe and troops of the United States Army. The Nez Perce captured about 150 horses and mules from a campsite of the pursuing army, and for several hours besieged a detachment sent to recover them at a second site.”
