From the Trail of Tears to Wounded Knee and Little Bighorn, the narrative of American history is incomplete without the inclusion of the Native Americans that lived on the continent before European settlers arrived in the 16th and 17th centuries. Since the first contact between natives and settlers, tribes like the Sioux, Cherokee, and Navajo have both fascinated and perplexed outsiders with their history, language, and culture.

The Shoshone are still remembered for their assistance, especially Sacagawea, and they maintained contact with Americans throughout the 19th century, but unfortunately, the cooperation gave way to conflict as white settlers began to move westward and enter onto lands occupied by the Shoshone. In 1862, California officials sent the Third California Volunteer Infantry under the command of Colonel Patrick Connor to construct a fort (Fort Douglas) in the foothills of the Wasatch Mountains above Salt Lake City, in an effort to keep lines of communication open so pioneers would not be hesitant about settling in the region. Meanwhile, Shoshone Chief Bear Hunter (Wirasuap) led his band on raids against mining camps and Mormon settlements.

In January 1863, Colonel Connor led 300 volunteers out of the newly completed Fort Douglas through 140 miles of bitter cold to reach Chief Bear Hunter's camp on the eastern shore of the Great Salt Lake, culminating in what would become known as the Bear River Massacre at Preston, Idaho. During the fighting, Connor's men trapped and killed an estimated 350 to 500 Northwestern Shoshone, including women, children, and the elderly. According to William Hull, a local settler sent to look for survivors, “After killing most of the men and many of the children, they raped and assaulted the women. In some cases, soldiers held the feet of infants by the heel and beat their brains out on any hard substance they could find. Women who resisted the soldiers were shot and killed. Never will I forget the scene, dead bodies were everywhere. I counted eight deep in one place and in several places they were three to five deep; all in all we counted nearly 400; two-thirds of this number being women and children. We found two Indian women alive whose thighs had been broken by the bullets. Two little boys and one little girl about three years of age were still living. The little girl was badly wounded, having eight flesh wounds in her body.”

This would be the highest number of fatalities suffered by the Shoshone at the hands of the US military, but the fighting was far from over. Capitalizing on their victory, which effectively ended what had been widely reported as “Wirasuap's War Path”, the federal government approved an open claim on the most hospitable lands of the Great Basin, leaving the Shoshone with the understanding that their lands would soon be lost to white ranchers, farmers, and prospectors.
