Fort Utah, which would eventually become Provo, was established in April 1849. Initial interactions with the nearby Utes were strained, yet Natives visited the fort. Despite tensions over livestock and resources, an uneasy peace was kept for a few months. This came to an unfortunate end when some of the settlers reacted rashly to a minor theft.
According to settler accounts, in January 1850 a Timpanogos Ute man stole a shirt from a clothesline at the Fort. In attempting to retrieve the shirt, three settlers shot and killed him. They then disposed of the body in the river. Members of the tribe discovered corpse, were enraged by the murder, and prepared to respond in force. To prepare a defense, Peter W. Cownover traveled to Salt Lake City to request reinforcement from the Deseret Militia. The militia left Salt Lake on February 7; in the meantime, the Utes under Big Elk fortified themselves in their camp on the banks of the Provo River. After negotiations failed, a two-day battle ensued. Neither side made significant advance until a final push from the Mormon settlers routed the Utes from their fortification and up towards the mountains. From the Provo River bottoms near present-day Bulldog Blvd. and State St. in Provo, Utes were pushed back towards the mouth of Rock Canyon.
In the end, Mormon casualties amounted to 1 killed and 18 wounded; of the Utes, at least three were killed including Big Elk and one woman, with an unknown number wounded. A group of the Indians surrendered and were offered asylum inside Fort Utah; another group went South to Spanish Fork and the remainder fled up the hill towards Rock Canyon where they were pursued and shot down, raising Indian casualties to between 40 and 100. One local telling links the naming of a peak above Rock Canyon to Big Elk's widow attempting to scale the cliff and falling to her death.
In the spring, the surviving Timpanogos Utes carried out raids in the Salt Lake Valley, killed settlers in the Sanpete Valley, and threatened to attack Chief Wakara (Walker) of a rival Ute band for cooperating with the Mormon settlers. Patsowett, the leader of the hostile group, was quickly captured and executed, ending that chapter in Utah’s ongoing Indian wars.
