In 1874 it was rumoured that gold had been found in the Black Hills of South Dakota so Lieutenant Colonel George Armstrong Custer was sent in to find out if this was true. After a search party had been sent out to look for the gold, small pieces were later found in the French creek, confirming the rumours of gold. Despite finding gold, the Black Hills were on Native American land, therefore meaning that they could not mine for themselves. Knowing that the buffalos were important to the natives, they came up with the concept that of you kill the buffalo, you kill the natives as they used the buffalo for their food, clothing etc. Although killing the buffalo was enough to rid the hills of a few natives, there were still many left so the Americans tried to buy the land from them but their offer was not enough for the natives. Failing yet another plan to buy the hills, the Americans arrested Native American Chiefs Crazy Horse and Sitting Bull to try blackmail the natives into giving up the black hills. The Indians retreated so the Americans thinking that their plan had succeeded, the Americans developed mines in the hills. But the Americans had found some natives still living in the hills and so Lieutenant Colonel George Armstrong Custer sent himself and a troop to get rid of them. Lieutenant Colonel Custer presumed that the natives would just run away as soon as they saw the Americans coming but this time, they did not. They attacked the Americans, killing 268 Americans and injuring 55. This was the greatest Native American victory and shamed the Americans. Today, the gold mines of the black hills are the richest mines in America with 1/10th of all Americas gold coming from these mines but the hills are still classed as Native American territory.
