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.
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.
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.
