[8] The massacre at Ash Hollow, often mentioned as a cause of the massacre at Okoboji, was the culmination of a campaign of terror planned by Gen. Harney against the Oglala and Brulé Sioux. The line of march was Fort Leavenworth, Fort Kearney, Fort Laramie, and Fort Pierre. At Ash Hollow near the Blue River and about four miles from the left bank of the North Platte he found Little Thunder’s band of the Brulé Sioux. When his cavalry had surrounded the Indians, he planned an advance with his infantry. Little Thunder desired a council. Gen. Harney refused, saying that he had come to fight. As Harney advanced, he motioned the Indians to run. They did so and ran directly into Harney’s cavalry. Finding themselves trapped, they fought savagely to the end. “The battle of Ash Hollow was little more than a massacre of the Brulés.... Though hailed as a great victory ... the battle of Ash Hollow was a ... disgrace to the officer who planned and executed it. The Indians were trapped and knew it ... and the massacre which ensued was as needless and as barbarous as any which the Dakotas have at any time visited upon the white people.”--Robinson’s _History of the Dakota or Sioux Indians_ in the _South Dakota Historical Collections_, Vol. II, pp. 224, 225.
