Fort Sill, a military post in Oklahoma used to imprison Apaches in the 1860s, is slated to house hundreds of undocumented children. Fort Sill is notably the place where Chiricahua Apache leader Geronimo died as a prisoner of war. It was also an internment camp for Japanese Americans during World War II.
