In April 1849, a group of about thirty families came into Utah Valley and settled on the Provo River, very close to the main Timpanogot village on the Provo River. The settlers built a stockade called Fort Utah and armed it with a twelve-pound cannon to intimidate the Timpanogots. In August, a Timpanogot named Old Bishop was murdered by three settlers over a shirt they wanted from him. Some Timpanogots shot at cattle or stole corn in response. Winter was especially hard and Timpanogots stole cattle for food. By January 1850, settlers of Fort Utah reported to officials in Salt Lake City that the situation was getting dangerous. They wanted a military party to attack the Timpanogots. A militia was sent from Salt Lake City and on February 8 and 11, and they engaged the Timpanogots in battle. On February 14, eleven Timpanogots surrendered, but were later executed while their families watched. A government surgeon went to the execution site and cut off the Timpanogots' heads for later examination. One militia man and 102 Timpanogots were killed. Over the ensuing years, fewer and fewer Timpanogots lived in Utah Valley and by 1872 all Timpanogots had moved to the Uintah and Ouray Indian Reservation. However, some Timpanogots occasionally returned to fish on Utah Lake into the 1920s.
