"Thirty-five of them went to the camp of the Gros Ventres and Assiniboines, who were adjacently camped near Fort Belknap, about twelve miles distant from the battleground.... They numbered about 200 or 300 lodges. They invited the Nez Perces into their lodges and gave them a feast. In the meantime, they took away their horses and arms, and then ordered them to leave on foot and without arms. After they had gone a short distance, the Gros Ventres and Assiniboines pursued them on horseback and shot down thirty-four of their number, one only escaping by concealing himself in a ravine. He succeeded in returning to the others, who were loitering around Miles, and that before the close of Miles' fight."
Today, the Fort Belknap Indian Reservation located in north central Montana near the Canadian border is home to two tribes which operate under one central government. The two tribes are the Assiniboine and the Gros Ventre.
