Mosquito, Grizzly Bear's Head, Lean Man First Nations

Lean Man took treaty on Sept 25th, 1877 at Fort Walsh (when a number of Assiniboine/Stoney bands took treaty) and the band's annuity payments appeared under Treaty 4, but no reserve lands were set aside for them until 1884. They have been considered a Treaty 6 band since 1882. On the official Treaty 4 Adhesion document, the Nakoda words "Wica Hostaka" are written by the X of Lean Man. In the Nakoda/Assiniboine language, 'Wica' means Man and "Hostaka" means Lean. During this period, as was the case with other bands, Lean Man did not take a reserve but continued to move back and forth across the border. In 1882, when Fort Walsh was closed, Lean Man moved north into Treaty 6 territory and were given a reserve along with Grizzly Bear's Head (reserve lands 110 and 111) - this band was therefore listed under Treaty 6 for all future treaty annuity payments. In 1885, the band participated in the 1885 rebellion and their annuities were suspended from 1885 to 1887. Many band members fled to the US along with other "Rebel Indians".

During the 1877 treaty adhesion meeting at Fort Walsh, some groups were refused permission to sign as they had been receiving annuity payments from the US in Montana. One such band was Little Chief's, a "British" band who had relocated to Montana. As had been the case with other bands, this group moved back and forth across the border, with both the Canadian and American authorities trying to stop the cross-border movement. In 1879, Little Chief's band moved back into Canada and was paid annuity, listed in the Treaty 4 paylist and paid the arrears for 1876 to 1878. There is no indication that Little Chief took a formal adhesion to the treaty. In 1880, Chief Bear's Head is listed as the chief of the band and the band is subsequently listed as "Bear's Head band". In 1882 after the closure of Fort Walsh and as part of the same move as Lean Man, the band relocated northwards to the same reserve as Lean Man's (reserve lands 110 and 111) and was therefore listed under Treaty 6 for all future treaty annuity payments. During the 1885 Rebellion, Grizzly Bear's Head rose up against the Crown. Just like Lean Man, their annuities were suspended between 1885 and 1887. After the Rebellion, the majority of the band fled to the US or dispersed to other bands.

Chief Misketo (also known as Sukeman) signed an adhesion to Treaty 6 on August 29, 1878, and record of their annuity payment appears in the 1878 Treaty 6 paylist. The survey for their reserve lands were conducted in 1879 and were adjacent to those of Red Pheasant in the Eagle Hills (reserve no. 109 - this reserve was surrendered in 1905). The band participated in the 1885 Rebellion against the Crown and their annuities were subsequently suspended between 1885 and 1887. After the Rebellion, a large number of the band fled to the US or dispersed to other bands.

Chief Mosquito would remain the Primary Chief of the Three bands of Mosquito, Grizzly Bears Head, Lean Man First Nations. Mosquito Grizzly Bears Head Lean Man Band is regarded as a member of the Treaty Four and Treaty Six areas, and is the only band in Canada with this status. Treaty Four Gatherings in Fort QuAppelle area reserve a place in their Council Meetings for the Mosquito Grizzly Bears Head Lean Man Band to this day.
