Red River Campaign
After the Indian uprising and attacks on buffalo hunters, President Grant put the army in charge of the natives in the west. Some native americans registered at a reservation and lived peacefully but the ones that didn't were mostly Comanches, Kiowas, and Cheyenne. Most of the aggressive ones based their camps in canyons.
There were around 1,200 native americans prepared to make their last stand aginst the Texan army. An army of 3,000 troops moved in to dispatch of the camps. The first battle occured in August 1874 but the soldiers didn't halt their progress until the following Spring. In the 1st 17 months they had fought at least 20 battles.
