So, What Happened?

In 1874, General Custer led an expedition to the black hills, which at that time, was owned by the Sioux tribe. He was there to see if the rumors of gold in the hills were true. They were. Soon after, miners started to pour into the area. Some older leaders were just going to give in to the requests of the Americans. Some of the younger Chiefs, like Sitting Bull and Crazy Horse, wanted to fight them. Sitting Bull Urged the Sioux to oppose the Americans offer’s to buy back the Black Hills from them.
In late 1975, reservation agents ordered the Sioux to be in the reservation by the end of January 1876, and remain there. They didn’t and continued to hunt outside their given area. Later, a large group of Sioux and others met in South-East Montana, along the Little Bighorn River.
In June of 25 1876, saw Custer march over 200 men into a village that probably had over 2000 Sioux Warriors in it. This was when the battle of Little Bighorn began. Custer and his men were killed by the Sioux.
Though the Sioux won this battle, they could not win against the Americans. The American Army stopped the town from getting food and starved the Sioux into surrender.
After all this, Crazy Horse gave himself up at the Red Cloud agency in Nebraska. That September, he was shot during a fight and bled to death in a reservation jail.
Sitting Bull and his followers fled to Canada, but returned in1881, and surrendered.
