Battle at Fort Utah: The Battle at Fort Utah (also known at Fort Utah War or Provo War) was a battle between the Timpanogos Tribe and remnants of the Nauvoo Legion at Fort Utah in modern-day Provo, Utah.  The Timpanogos people initially tolerated the presence of the settlers, and the two groups enjoyed some moments of mutual friendship.  However, after three Mormons murdered a Timpanogos man called Old Bishop and a hard winter where Timpanogos took around 50 Mormon cattle, settlers in Fort Utah petitioned to go to war with the Timpanogos.  Isaac Higbee, Parley P. Pratt and Willard Richards convinced Brigham Young to exterminate any Timpanogos hostile to the Mormon settlement.  Young sent the Nauvoo Legion down with Captain George D. Grant.  and later sent General Daniel H. Wells to lead the army.  After the Timpanogos defended themselves from their village and an abandoned cabin, they fled their camp.  The Mormons pursued the Timpanogos from Chief Old Elk's tribe and any other Timpanogos they found in the valley, killing Timpanogos from Chief Old Elk's tribe and other tribes even if they had no history of attacking the Mormons.  The Nauvoo Legion killed around 100 Timpanogos.

United States v. Quiver: United States v. Quiver, 241 U.S. 602 (1916) is a case decided by the United States Supreme Court after first appearing in United States District Court for the District of South Dakota.  The case argued on February 28, 1916 and decided on June 12, 1916 concerned adultery committed on the Pine Ridge Indian Reservation in South Dakota between two enrolled members of the Oglala Sioux Tribe.  The district court had held that adultery committed by an Indian with another Indian on an Indian reservation was not punishable under the act of March 3, 1887, c. 397, 24 Stat.  635, now § 316 of the Penal Code.  This decision was made because the offense occurred on a Sioux Indian reservation which is not said to be under jurisdiction of the district court.  The United States Supreme Court affirmed the judgment of the district court saying that the adultery was not punishable as it had occurred between two American Indians on an American Indian reservation.
