History: American Old West, United States

The end of the Sioux Wars came at the Wounded Knee Massacre on December 29, 1890 where Sitting Bull's half-brother, Big Foot, and some 200 Sioux were killed by the 7th Cavalry. Only thirteen days before, Sitting Bull had been killed with his son Crow Foot in a gun battle with a group of Indian police that had been sent by the American government to arrest him.
Other engagements between Americans and native Americans occurred after the massacre at Wounded Knee in 1890 which is considered the final trial of the American Indian Wars. The period came to an end in 1918 after the skirmish in Arizona locally called the Battle of Bear Valley. In the fight, the 10th Cavalry captured a group of Yaquis and killed their chief. In 1907 two soldiers from Fort Wingate, New Mexico skirmished with Navajo rifleman and in 1911 they quelled an uprising in Chaco Canyon. Also in 1911 the Last Massacre occurred when a family of hostile Shoshones killed three ranchers in Nevada. A posse was formed and after an engagement popularly called the Battle of Kelly Creek, the Shoshone family of twelve was mostly killed with the exception of three children.
• Johnson County War
The 1892 Johnson County range war took place in Wyoming's Powder River country. The large ranches were organized as the Wyoming Stock Growers Association and hired killers from Texas; an expedition of fifty men was organized, which proceeded by train from Cheyenne to Casper, then toward Johnson County, intending to eliminate alleged rustlers and also, apparently, to replace the government in Johnson County. After initial hostilities, the sheriff of Johnson County raised a posse of 200 men and set out for the ruffians' location. The posse led by the sheriff besieged the invading force at the TA Ranch on Crazy Woman Creek. After two days, one of the invaders escaped and was able to contact the acting governor of Wyoming. Frantic efforts to save the besieged invaders ensued, and telegraphs to Washington resulted in intervention by President Benjamin Harrison. The Sixth Cavalry from Fort McKinney was ordered to proceed to the TA ranch and take custody of the invaders and save them from the posse. In the end, the invaders went free after the court venue was changed and the charges were dropped.
