When gold was discovered in 1875 in South Dakota's Black Hills, the U.S. Army began to ignore treaty agreements they had made with Native Americans and they started to invade the region. By late spring of 1876, more than 10,000 Native Americans had gathered in a camp along the Little Bighorn River to prepare for any U.S. military attacks.
The Black Hills are a small and isolated mountain range rising from the Great Plains of North America in western South Dakota and extending into Wyoming, United States. Minnie Hollow Wood and her family lived in the Black Hills.
The Battle of the Little Bighorn, fought on June 25, 1876, took place near the Little Bighorn River in Montana Territory, not far from Black Hills, South Dakota. By mid-day, Lieutenant Colonel George Armstrong Custer led his U.S. Army 7th Calvary into the Little Bighorn Valley. Custer and the 200 men in his battalion were confronted by as many as 3,000 Native Americans and within an hour, Custer and all of his soldiers were dead.
