Much about Washakie's early life remains unknown, but some information is revealed. Washakie was born between 1798 and 1810. The information below is mostly cited to Oregon historian Gale Ontko — who did extensive research and wrote a five volume popular history on the Western Shoshones, but whose interpretations and details vary from many other Shoshone historians that make no mention of Washakie having a connection to the Oregon Country. According to Ontko, Washakie's mother Lost Woman was a
Tussawehee (White Knife) Shoshone by birth. While most sources say his father was a Flathead, Ontko writes his father, Crooked Leg (Paseego), was an Umatilla rescued as a boy from slave traders at Wakemap and Celilo on the Columbia River in 1786 by Weasel Lungs, a Tussawehee dog soldier (White Knife) Shoshone medicine man. Crooked Leg was adopted into Weasel Lungs' clan. According to Ontko, Pinaquanah met his first white men in 1811.
Wilson Hunt's main party of Astorians, with the
Pacific Fur brigade, were traveling down the
Boise River from the mouth of the
Bruneau River. Seven months late for their scheduled arrival at
Fort Astoria, they happened into Crooked Leg's camp on the Boise. They needed horses, which Crooked Leg refused to sell to them; instead reluctantly selling them a few
camas roots, dried fish, and four dogs. While Ontko details this incident, Hunt diaries from the date Ontko cites make no mention of Crooked Leg or Washakie. According to Ontko, Crooked Leg was killed in 1824 by members of the
Piegan Blackfeet when they raided a Shoshone hunting camp inside the Blackfoot hunting boundary. He demonstrated the horsemanship of Shoshone riders to Crook, and some of the riders took an active role in scouting with the Army, but Washakie himself was nearly 70 years old at this time and not as active as the younger scouts. However his support by providing scouts was helpful to the US Army. The year of Washakie's birth date is debated. A missionary in 1883 recorded the year of his birth as 1798, but his tombstone was later inscribed with a birth date of 1804. Late in his life he told an agent at the Shoshone Agency that when he was 16, he had met
Jim Bridger. Interpolating from the age of Bridger when he first went into the wilderness, researchers have determined that Washakie was likely born between 1808 and 1810. During his early childhood, the
Blackfeet Indians attacked a combined camp of Flathead and Lemhi people while the latter were on a buffalo hunt near
Three Forks, Gallatin County, Montana (where the Gallatin, Madison, and Jefferson Rivers form the headwaters of the
Missouri River). After Crooked Leg was killed, his mother and at least one sister were able to make their way back to the Lemhis on the Salmon River in Idaho. During the attack, Washakie was lost and possibly wounded. According to some family traditions, he was found by either
Bannock Indians who had also come to hunt in the region, or by a combined Shoshone and Bannock band. He may have become the adopted son of the band leader. For the next twenty five years (c. 1815–1840) he learned the traditions and ways of a warrior that were typical of any Shoshone youth of that period. Although the name by which he would be widely known has been translated in various ways, it apparently dealt with his tactics in battle. One story describes how Washakie devised a large rattle by placing stones in an inflated and dried balloon of buffalo hide, which he tied on a stick. He carried the device into battle to frighten enemy horses, earning the name "The Rattle" or "Gourd Rattler". Another translation of "Washakie" is "Shoots-on-the-Run." == Military career ==
