Fr Emil Kapaun was a Catholic chaplain during WWII and the Korean War. He is also on a road to possible sainthood.
He was captured during the Korean War and led his soldiers to resist the propaganda efforts of the commies as well as keep up their spirits and help them live their faith. For his trouble, the Communist Chinese forces holding him captive took him to a "hospital" when he got sick. In reality they left him to die in a shack separated from the soldiers he loved so much.
