Military

The history of nuclear weapons in Wyoming is intimately connected to the F. E. Warren Air Force Base, which in turn is tied to the global development of rocketry and nuclear might. If Wyoming were a nation, Warren AFB in Cheyenne would make it one of the world’s major nuclear powers. Its history with nuclear weapons in Wyoming is tied closely to the worldwide tensions of the Cold War, and with the development of missile-based nuclear weapons systems.

On Aug. 2, 1867, a large force of Oglala Sioux attacked woodcutters near Fort Phil Kearny. Soldiers assigned to protect the woodcutters took cover behind a ring of wagon boxes. After the intense battle, both sides claimed victory, and estimates of the dead and wounded varied widely.

In November 1876, about 700 cavalry and 400 Indian scouts led by Col. Ranald Mackenzie, burned the main village of the Northern Cheyenne to the ground near the Red Fork of Powder River about 20 miles west of present Kaycee, Wyo. Seven soldiers were killed and about 40 Cheyenne, but the economic and cultural loss to the tribe was devastating. The Northern Cheyenne surrendered to government authorities the following spring.

Two battles on July 26, 1865 near Platte Bridge Station near present-day Casper, Wyo., are best understood in the context of tribal response to the Sand Creek Massacre the previous November. Twenty-eight U.S. troops were killed that day including Lt. Caspar Collins, for whom Fort Caspar and the town of Casper were later named.

When the U.S. Army in 1866 sent troops to build a string of forts along the Bozeman Trail north from the North Platte River to the Montana gold fields, Lakota, Cheyenne and Arapaho tribes in that country reacted angrily. For two years, the tribes harassed and attacked the soldiers and travelers on the trail. After the Treaty of Fort Laramie in 1868, the Army withdrew, the Indians burnt the forts and for a few years, until hostilities started up again in the mid-1870s, the tribes the country largely to themselves.

In March 1866, when whites and Indians together at Fort Laramie mourned the death of Mni Akuwin, daughter of Spotted Tail, chief of the Brulé Lakota, a colonel at the post hoped it was a sign of peace between the peoples. Peace hopes were shattered later that spring however, by the arrival of hundreds of troops to build forts on the Bozeman Trail, and two more years of bitter warfare followed. Finally in 1868, the tribes of the northern plains gathered at the fort and signed a treaty, ending the war—for a while.

In 1943, Cpl. Leon Tebbetts and three other soldier-artists were among the thousands of troops stationed at the U.S. Army Air Base in Casper. They created 15 murals showing major events in Wyoming history on the interior walls of the Servicemen’s Club. The colorful murals have been well preserved and can still be seen today at the same place—now the Wyoming Veterans Memorial Museum.

Near Fort Phil Kearny in December 1866 in what’s now northern Wyoming, Lakota Sioux and Cheyenne warriors ambushed and killed Capt. William Fetterman and his entire command of 80 men. Fetterman’s arrogance has long been blamed for the disaster, but new evidence shows a more complex and nuanced story.

Fort Phil Kearny, near present-day Story, Wyo., was established by the U.S. Army in the summer of 1866 to protect travelers on the Bozeman Trail from Indian attack. and abandoned two years later, under terms of the1868 Treaty of Fort Laramie. Indians burned the fort shortly after the army left.
