Yuma War
The Yuma War was the name given to a series of United States military operations conducted in southern California and what is today southwestern Arizona from 1850 to 1853. The Yumans were the primary opponent of the United States Army, though engagements were fought between the Americans and other native groups in the region. Conflict generally took the form of guerrilla warfare, and, over the course of three years, the army engaged in pursuing unfriendly natives, protecting American settlers crossing the Colorado River and preventing conflict between the native tribes. A peace treaty in summer of 1853 was signed, ending hostilities between the Yuma and the United States, but it sparked a short war between the Yuma and the Cocopah. During the conflict, the historic Fort Yuma was constructed and became an important outpost on the frontier.
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.
