The Battle of Slim Buttes was fought on September 9 and 10, 1876, in the Great Sioux Reservation between the United States Army and the Sioux. The Battle of Slim Buttes was the first U.S. Army victory after General George Custer’s defeat at the Battle of Little Bighorn on June 25 and 26, 1876, in the Great Sioux War of 1876–1877. Brigadier General George R. Crook, one of the U.S. Army’s ablest Indian fighters, led the “Horsemeat March”, one of the most grueling military expeditions in American history, destroying Oglala Chief American Horse’s village at Slim Buttes and repelling a counter-attack by Crazy Horse. The American public was fixed on news of the defeat of Custer at the Battle of Little Bighorn and war correspondents with national newspapers fought alongside General Crook and reported the events. The Battle of Slim Buttes signaled a series of punitive blows that ultimately broke Sioux armed resistance to reservation captivity and forced their loss of the Black Hills “Paha Sapa“.
