Hogan's Heroes is my all-time favorite TV show. Hogan's Heroes ran for six seasons from 1965 thru 1971. It was set in a POW camp called Stalag 13 in Germany during WWII. Stalag 13 was run by the blundering German Col. Klink and his bungling but hilarious sidekick Sgt. Schultz. The Allied soldiers were under the command of Col. Hogan, who were POW's in Stalag 13. Col. Hogan and his men's real mission was actually to sabotage the German war effort and aid escaping POW's to England from Stalag 13.
Col. Hogan was played by the actor Bob Crane in Hogan's Heroes. He was the senior officer of the Allied prisoners in Stalag 13. His mission was to lead a group of Allied POWs to sabotage the German war effort and to help Allied POWs escape to England.
