Leonard Stanisław (1865-1899) was a US Army soldier who was stationed at Fort Wallace in South Dakota during the Wapiti War. Born in Milwaukee to a Polish family, he took part in the destruction of a Wapiti sacred site in the Black Hills before returning to camp and chatting with another soldier, David Cottrill Alexander, about their families and about Native Americans. They were both gunned down by the outlaw Arthur Morgan when he infiltrated the camp to retrieve the sacred chanupa pipe they had stolen.
