Cause

Years of skirmishes, food raids on settlers' farms and ranches, and the displacement of Shoshone people from their ancestral lands created escalating tension between Northern Shoshone communities and US settlers and military forces in the region. These conflicts prompted the US Army to organize the Bear River Expedition targeting Shoshone chief Bear Hunter.

Event

On January 29, 1863, Colonel Patrick Edward Connor led a detachment of California Volunteers in a dawn assault on a large Northern Shoshone winter encampment at the confluence of the Bear River and Battle Creek in what was then southeastern Washington Territory. Between 250 and 493 Shoshone — including children, women, and men — were killed, making it among the deadliest military attacks on Native Americans in US history.

Consequence

The massacre effectively destroyed the Northern Shoshone community centered around Bear Hunter's band, opening the region to further settler expansion. It is described by some sources as the largest single episode of genocide in US history, though it remained largely obscured in national historical memory for generations before gaining wider recognition.
