⚔️ The Army’s Orders Were Simple: Attack the Village, Take No Prisoners — Connor Battlefield State Historic Site near Ranchester, Sheridan County, Wyoming, Battle of Tongue River (August 29, 1865), General Patrick Edward Connor’s Powder River Expedition, attack on Northern Arapaho village of Chief Black Bear, 250 tipis burned, 500+ horses captured, Indian Wars on the Great Plains — Sheridan County, WY

On August 29, 1865 — four months after the Civil War ended — General Patrick Edward Connor marched 300 soldiers into the Tongue River valley and attacked a Northern Arapaho village. His orders, issued to himself as expedition commander, were blunt: “You will not receive overtures of peace or submission from Indians, but will attack and kill every male Indian over twelve years of age.”

Connor’s men burned 250 tipis, captured over 500 horses, and destroyed the village’s winter food supply. The Arapaho, led by Chief Black Bear, counterattacked and nearly overwhelmed the soldiers before Connor withdrew. The battle achieved nothing strategically — but it hardened Native resistance across the northern Plains for the next decade.

Frequently Asked Questions

Did Connor’s orders really say to kill every male over twelve?

Yes. Connor’s General Order No. 2 for the Powder River Expedition stated: “You will not receive overtures of peace or submission from Indians, but will attack and kill every male Indian over twelve years of age.” While this order was not fully carried out, it reveals the brutality of U.S. military policy on the Plains.

What happened to the Arapaho after the battle?

They lost their village, their horses, and their winter food — but they survived. The Northern Arapaho regrouped, allied with the Lakota and Cheyenne, and fought in the conflicts that followed, including Red Cloud’s War. Today, the Northern Arapaho live on the Wind River Reservation in central Wyoming.

Was the Powder River Expedition successful?

No — it was a military failure. Connor’s attack on the village was the expedition’s only engagement. Supply lines collapsed, other columns wandered aimlessly, and Connor was relieved of command. The expedition achieved nothing except hardening Native resistance.

⚔️ “Kill Every Male Over Twelve” — The Order That Started a Decade of War

250 tipis burned. 500 horses captured. Then the Arapaho counterattacked. The Powder River Expedition failed — but it lit a fuse that burned through Red Cloud’s War and all the way to Little Bighorn.
