Members of the Cheyenne River Indian Reservation are proud ancestors of family members who participated in every major event in Lakota`s history, including the arrival of French explorers La Verendrye Brothers Expedition 1743 and 1804 Lewis and Clark Expedition encounters; 1854 Grattan Incident; Conference of the Fort-Laramie Treaty of 1851 and 1868; 1862 Band of mad soldiers rescue prisoners; Bozeman Trail Wars – (including the Fetterman Fight of 1866; 1867 Wagon Box Fight; 1867 Hayfield Fight); 1876 Battle of the Rosebud and Battle of the Little Bighorn; 1876 Slim Buttes Battle; 1876-1881 Hiking canada and capitulating Canada; February 1877 Capitulation/arrival at Spotted Elk`s Cheyenne River (Si Tanka/Big Foot); April-May 1877 Capitulation of the group leader Crazy Horse, Hump, Touch The Cloud, Blade Deer (killed at the handover of his band) and Dull Knife (Chief of Cheyenne Tribe); September 5, 1877 Crazy Horse put to death at Camp Robinson; 1887 Dawes Allotment Act and beginning of the reservist period; 1889-90 Ghost Dance Bewegung/Sitting Bull Slaughter at Standing Rock and Wounded Knee Massacre of Spotted Elk (aka Si Tanka/Big Foot and his followers. This famous Spotted Elk is known as Big Foot, but his family members have always known him as Spotted Elk. He was called Si Tanka (Big Foot) just before the injured knee massacre of 1890, due to an incident that occurred concerning his boot/moccasine. There are many photos attributed to him by different people, but very few are him. The Lakota of the Cheyenne River still have their men and leaders today. In 1887, Congress passed the General Allotment Act, also known as the Dawes Act, to divide Indian municipal lands into individual families. On March 2, 1889, Congress passed another law (just a few months before joining the Union of North and South Dakota on November 2, 1889) that divided the Great Sioux Reservation and created five minor reservations: the Sioux Agreement of 1889 set reservation limits and was called Cheyenne River Sioux Reservation. To the west of the Missouri River was the water of the Cheyenne River, known as the Good River (Wakpa Waste). The Post at Cheyenne River Agency was founded in 1870, seven miles above Fort Sully, on the Missouri River, and is known as Fort Bennett. Fort Bennett was next to the village of Cheyenne Agency and was the quarter of the Indian agent and soldiers. Separated from the fortress was the city of the agency, which housed U.S.
government employees, and this site was then moved to higher positions away from the river. The fortress and town were moved four times in the coming years, with the name Cheyenne Agency adjacent to the nearby town of Fort Bennett. As the reserve was surrendered under the Dawes Act of 1887, the city was relocated because it was now far from the new reservation limits. After 1891, Fort Bennett was closed by the army and the reserve was considered safe with no military fortress next door. The closest location to the agency would be between the Cheyenne River (Good River) and the Moreau River (Owl) at the site of Chief Martin Charger`s camp. It was called the Cheyenne Agency. The first cities were Evarts, then LeBeau, which were commercial posts. LeBeau was founded by Antoine LeBeau, a French distributor.
Evarts and LeBeau no longer existed when rail traffic ran out and the town of LeBeau burned. Both sites are now under the missouri River. The former main camps of Minnicoujou were located in the towns of Cherry Creek, Bridger and Red Scaffold, west of the reserve. Cherry Creek is probably the oldest permanent community in South Dakota. The original Oohenumpa camps ranged from Iron Lightning, Thunder Butte, Bear Creek and White Horse along the Moreau River (Owl). Siha Sapa is located around the Promise and Blackfoot areas in the northeastern part of the reserve.
