After having endured five weeks of difficult pursuit of Sioux hostiles he had been ordered to punish, General H.H. Sibley and his 2000 men caught up with the main body of the Santee Sioux at Big Mound in present-day Kidder County, North Dakota. There, after attempts to negotiate broke down when an Army doctor was murdered, a running fight under gray skies ended with defeat for the hostiles, who broke away to the west. The Sioux suffered around eighty killed and wounded while Sibley lost three men killed, one of them by lighting. (By John Osborne)
