Action 14f13, also called Sonderbehandlung (special treatment) 14f13 and Aktion 14f13, was a campaign by Nazi Germany to murder Nazi concentration camp prisoners. As part of the campaign, also called invalid or prisoner euthanasia, the sick, the elderly and those prisoners who were no longer deemed fit for work were separated from the rest of the prisoners during a selection process, after which they were murdered.^[1] The Nazi campaign was in operation from 1941 to 1944 and later covered other groups of concentration camp prisoners.^[2]
