When the bison stayed away and made hunting impossible, famine became a reality. The hard experience of starvation found way into stories and myths. A folk tale of the Kiowa begins "Famine once struck the Kiowa People..." "The people were without food and no game could be found..." makes an Omaha myth certain. A fur trader noted how some Sioux were in want of meat at one time in 1804. Starving Yanktonais passed by Fort Clark in 1836. Diminishing herds and the effects on tribes Already Castaneda noted the typical relations of two different plains people relying heavily on the same food source: "they ... are enemies of each other." The bison hunting resulted in loss of land for a number of tribal nations. Indirectly, it often disturbed the rhythm of a tribal life, caused economic losses and hardship, and damaged tribal autonomy. As long as bison hunting went on, intertribal warfare was omnipresent. Loss of land and disputes over the hunting grounds Tribes forced away from the game rich areas had to try their luck on the edges of the best buffalo habitats. Small tribes found it hard to do even that. Due to attacks in the 1850s and 1860s, the villages of the Upper Missouri "hardly dared go into the plains to hunt buffalo". The Sioux would stay near Arikara villages "and keep the bison away, so they could sell meat and hides to the Arikaras". The Kiowas have an early history in parts of present-day Montana and South Dakota. Here they fought the Cheyenne, "who challenged their right to hunt buffalo". Later, the Kiowas headed for the south together with the Comanche, when "the Lakota (Teton Sioux) drove them from the Black Hills territory". In present-day Montana, the better-armed Blackfoot pushed the Kutenai, Flathead and Shoshone off the plains. In the start of the 19th century, they claimed the buffalo ranges entirely to the Rocky Mountains and fought all conceived as intruders. The less numerical tribe peoples west of the continental divide did not accept this. Their ancestors had hunted on the Great Plains and they would continue the tradition at all cost. "When we go to hunt Bison, we also prepare for war with the Peeagans [Piegan Blackfeet] and their allies", revealed a Flathead chief. A Kutenai gave this description of tribal hunts during buffalo days, "Across the mountains they went out on the prairie, but
