Answer 1

The Sand Creek massacre (also known as the Chivington massacre or the Battle of Sand Creek) was an incident in the Indian Wars of the United States that occurred on November 29, 1864, when Colorado Territory militia attacked a village of Cheyenne and Arapaho encamped on the eastern plains.

The Battle of the Little Bighorn — also known as Custer's Last Stand and Custer Massacre and, in the parlance of the relevant Native Americans, the Battle of the Greasy Grass — was an armed engagement between a Lakota-Northern Cheyenne combined force and the 7th Cavalry of the United States Army. It occurred June 25–June 26, 1876, near the Little Bighorn River in the eastern Montana Territory.
The battle was the most famous incident in the Indian Wars and was a remarkable victory for the Lakota and Northern Cheyenne. A U.S. cavalry detachment commanded by Lt. Col. George Armstrong Custer was annihilated

Wounded Knee Massacre was the last major armed conflict between the Dakota Sioux and the United States, subsequently described as a "massacre" by General Nelson A. Miles in a letter to the Commissioner of Indian Affairs.
On December 29, 1890, five hundred troops of the U.S. 7th Cavalry, supported by four Hotchkiss guns (a lightweight artillery piece capable of rapid fire), surrounded an encampment of Miniconjou Sioux and Hunkpapa Sioux with orders to escort them to the railroad for transport to Omaha, Nebraska. The commander of the 7th had been ordered to disarm the Lakota before proceeding and placed his men in too close proximity to the Lakota, alarming them. Shooting broke out near the end of the disarmament, and accounts differ regarding who fired first and why.
