The Great Sioux Uprise Entry from the "Timeline of American-Indian Relations" in Fleming & Luskey, The North American Indians in Early Photographs:

1862, Santee Sioux Revolt led by Little Crow. The Santee had yielded most of their land in return for annuities, which were not paid on time; white traders tricked them out of much of their money. Little Crow's revolt is defeatd by General Henry H. Sibley; Little Crow is killed the following year while on a raspberry expedition.

Quotes from Brown, Chapter 5: "Little Crow's War (39-65):"

Meanwhile Sibley had chosen five of his officers to form a military court to try all Santees suspected of engaging in the uprising. As the Indians had no legal rights, he saw no reason to appoint a defense counsel for them.

303 Santees had been sentenced to death, sixteen to long prison terms.

President Lincoln notified Sibley that he should "cause to be executed" thirty-nine of the 303 convicted Santees. ... a spectator boasted that it was "America's greatest mass execution."

The state of Minnesota presented the settlers who had killed Little Crow with the regular scalp bounty and a bonus of five hundred dollars.

The day of the Santee Sioux in Minnesota now came to an end. Although most of the war chiefs and warriors were dead, in prison, or far beyond the borders of the state, the uprising had given the white citizens an opportunity to seize the Santees' remaining lands without even a pretense of payment.  .... "Exterminate or banish," was the cry of land-hungry settlers."
