Battle of the Rosebud on the reservation by January 31, 1876 to negotiate the sale. A few bands did not comply and when the deadline of January 31 passed the US undertook to force Sitting Bull, Crazy Horse, and their followers onto the reservation. The first military expedition against the recalcitrant Indians in March 1876 was a failure, ending in the Battle of Powder River. In June 1876, the US military renewed the fight with a three-pronged invasion of the Bighorn and Powder river country. Colonel John Gibbon led a force from the west; General Alfred Terry (with Lieutenant Colonel George Armstrong Custer) came
Bury My Heart at Wounded Knee Hills, angering the Lakota and Dakota living there. A peace council in 1875 tried to arrange for the US government to either purchase the mineral rights or outright ownership of the Black Hills, but both proposals were rejected by the Sioux. In 1876, a series of battles occur between the Sioux and US troops which initially ends when the Sioux defeat General Custer and his troops at the Battle of Little Bighorn on June 25. The humiliated US Army sends a peace council to sign a treaty that forces the Sioux out of the Black Hills to the Missouri River.
