On this day, September 28, in 1874

 The Battle of Palo Duro Canyon was fought marking the end of the Red River War and the final defeat of Native American resistance in the Southern Plains. The Red River War was a military campaign launched by the US Army in 1874 to clear out the South Plains for white settlers and forcibly relocate the Native American tribes who lived there onto Indian reservations. The reservations proved to be small, inadequate and prone to violence from white settlers causing many tribes to leave. Palo Duro Canyon was significant because the Comanche, Cheyenne, Kiowa and Arapaho tribes had stored food and supplies there for the winter so after it was destroyed they had to return to the Fort Sill reservation.
