Bear River massacre
The Bear River Massacre, or the Battle of Bear River and the Massacre at Boa Ogoi, took place in present-day Idaho on January 29, 1863. The United States Army attacked Shoshone gathered at the confluence of the Bear River and Beaver Creek in what was then southeastern Washington Territory. The site is located near the present-day city of Preston in Franklin County, Idaho. Colonel Patrick Edward Connor led a detachment of California Volunteers as part of the Bear River Expedition against Shoshone Chief Bear Hunter.
Early history and causes
Cache Valley, originally called Seuhubeogoi (Shoshone for "Willow Valley"), was the traditional hunting ground for the Northwestern Shoshone. They gathered grain and grass seeds there, as well as hunting small game such as woodchuck and ground squirrel; large game animals including deer, elk, and buffalo; and fishing for trout from the rivers.[2] This mountain valley had attracted fur trappers such as Jim Bridger and Jedediah Smith, who visited the region. Cache Valley was named for the trappers' practice of leaving stores of furs and goods (i.e., a cache) in the valley as a base for hunting in the surrounding mountain ranges.[3]
