Although many Comanches had moved south of the Arkansas after 1750, the Yamparika and Jupe bands remained to the north of the Arkansas. As late as 1805, the North Platte was still known as the Padouca Fork, and by this time, Padouca meant Comanche. As late as 1775, the Yamparika were still fighting the Lakota and Cheyenne near the Black Hills and raiding the Arikara villages along the Missouri River. Frequent wars also occurred with the Pawnee, Kansa, and Osage, usually over horses. Comanches usually had more horses than they needed; Pawnee, Kansa, and Osage did not, and dealing with a Comanche horse trader could be frustrating. Often, the solution was to shoot the Comanche (having recently acquired guns from French traders on the Missouri River) and take the horse, and this meant war.
