The Paiute War, also known as the Pyramid Lake War, Washoe Indian War and the Pah Ute War, was an armed conflict between Northern Paiutes allied with the Shoshone and the Bannock against intruding settlers from the United States, supported by military forces. It took place in May 1860 in the vicinity of Pyramid Lake in the Utah Territory, now in the northwest corner of present US state of Nevada. The war was preceded by a series of increasingly violent incidents, culminating in two pitched battles in which approximately eighty settlers were killed. The number of Paiutes killed in action is unrecorded. Smaller raids and skirmishes continued until a cease-fire was agreed to in August 1860; there was no treaty.
