[1] After nearly half the Southern Cheyenne died in the cholera epidemic of 1849, many of the remaining Masikota band joined the Dog Soldiers.

[11] Other elements contributing to the breakdown of the traditional clan system were the high rate of deaths from the 1849 cholera epidemic, which killed perhaps half the Southern Cheyenne population,[14] particularly devastating the Masikota band and nearly wiping out the Oktoguna.
[17] By the 1860s, as conflict between Indigenous people and whites intensified, the militaristic Dog Soldiers increased their influence, together with that of the warrior societies of other Cheyenne bands.
The warriors became a significant counter-influence to the leadership of the traditional Council of Forty-Four chiefs, who were likely to favor working for peace with the whites.
Dog Soldiers refused to sign treaties that limited their hunting grounds and restricted them to a reservation south of the Arkansas River.
They attempted to hold their traditional lands at Smoky Hill, but the campaigns of General Philip Sheridan foiled these efforts.
Attacked by General Eugene Carr, the Dog Soldiers began raiding settlements on Smoky Hill River in revenge.
After raiding sites in Kansas, they were attacked by a force composed of Pawnee Scouts led by Major Frank North, and United States cavalry, who killed 23 of an estimated 450 Cheyenne warriors (5%), including Tall Bull, in the Battle of Summit Springs in June 1869.
