History
In 1878, the Sappa Creek valley in Kansas was the scene of the last raid by Native Americans (Indians) in Kansas. In the Northern Cheyenne Exodus after the Battle of Punished Woman's Fork, a band of Cheyenne needing horses and provisions raged through the valley, killing more than 30 civilians and raping several woman. Several Cheyenne elderly, women, and children were also killed in the region by soldiers and civilians.{{cite book |last1=Leiker |first1=James N. |last2=Powers |first2=Ramon |title=The Northern Cheyenne Exodus in History and Memory |date=2011 |publisher=University of Oklahoma Press |location=Norman |isbn=9780806142210 |pages=59-67}} In Oberlin, the Decatur County Last Indian Raid Museum commemorates the Cheyenne raid.{{cite web |title=Decatur County Last Indian Raid Museum |url=https://www.dclirm.com/ |website=Decatur County |access-date=10 July 2022}}
