Agent Luther Mann of Fort Bridger added (1865, p. 327): They spend about eight months of the year among the Wind River mountains and in the valley of the Wind River, Big Horn and Yellowstone.... The Shoshonees are friendly with the Bannacks, their neighbor on the north ... but are hostile toward the tribes on their eastern boundaries, viz: Sioux, Arapahoes, Cheyennes, and Crows. Mann observed that the Eastern Shoshone numbered some 150 lodges. However, he also noted that Washakie claimed to be too weak to fight his enemies. In his next year's report, Mann wrote that on September 20, 1865, the Shoshone set out from Fort Bridger for the Wind River and Popo Agie valleys where they hunted buffalo, deer, elk, and mountain sheep and passed the winter. Only five to ten lodges remained on Green River for the winter (ibid., p. 126). The Shoshone had some difficulty with hostile tribes during their hunts in the Wind River Valley. The battle of Crowheart Butte (near Crowheart, Wyoming) has become a legend on the Wind River Reservation, and the facts of the event have become well embellished. More reliable informants claim that the Crow were encamped at the present site of Kinnear, Wyoming, on the north side of Big Wind River and were driven out after a strong attack by the Shoshone. The Crow detachment was evidently not merely a war party, for the men were accompanied by their women and children. Hebard, using documentary material unavailable to the writers, places the date of this battle as March, 1866 (Hebard, 1930, p. 151). There is no further mention in the sources of Crow occupation of the Wind River Valley. This was not the end of the Shoshones' troubles, however, for in the following year (1867), Indian Agent Mann noted (1868, p. 182): Immediately after the distribution of their annuity goods last year, they left this agency for their hunting grounds in the Popeaugie [Popo Agie River, near Lander, Wyo.] and Wind River valleys, the only portion of the country claimed by them where they can obtain buffalo. Early last spring the near approach of hostile Sioux and Cheyennes compelled them to leave before they could prepare their usual supply of dried meat for summer use. Mann further reported that, after being paid the annuity on June 8, 1867, "they have since gone to the valley of the Great Salt Lake, as is usual with them, preparatory to their return to their hunting grounds in autumn" (p. 183). These accounts further document the manner in which the Utah and Wyoming populations merged. The Sioux were apparently especially active east of the Wind River Range in these years and many other attacks were reported. The Shoshone went to Wind River in 1868 and were again attacked by the Sioux. Agent Mann reported that year that a few small bands of Shoshone had not hunted buffalo in two years for fear of attack (Mann, 1869, pp. 616-618).
