Superboy #91

After participating in a Smallville Civil War re-enactment, Superboy finds a planet where duplicates of his townsfolk are actually fighting the war. He tries and fails to save Clark Brent (a Clark Kent double) from a firing squad, only to find that he was actually a Confederate spy. He then tries and fails to save General Kane (Pa Kent), Private Rothul (Lex Luthor), and Nurse Bertha (Ma Kent). At length he learns that the people are all androids, with two elderly alien generals playing a war game.
