The Battle of Whitestone Hill (known also as Whitestone Hill Massacre by the Dakota) was a battle of the Sioux Wars in 1863 in the Dakota Territory as punishment against the Sioux in the aftermath of the Dakota War of 1862. From September 3-5, 1863, Brigadier General Alfred Sully led U.S. Army troops against a village of Yanktonai, Santee, and Teton (Lakota) Sioux. The reported casualties vary, but U.S. Army troops killed somewhere between 150 and 300 Sioux and captured between 150 and 250 Sioux, including women and children, and they suffered approximately 22 killed and 38 wounded.
