Hogan’s Heroes is a television sitcom set in a Nazi German
prisoner-of-war (POW) camp during World War II. It ran for
168 episodes (six seasons) from September 17, 1965, to
April 4, 1971, on the CBS network, the longest broadcast
run for an American television series inspired by that war.

Bob Crane starred as Colonel Robert E. Hogan, coordinating
an international crew of Allied prisoners running a special
operations group from the camp. Werner Klemperer played
Colonel Wilhelm Klink, the gullible commandant of the camp,
and John Banner played the blundering but lovable sergeant-
of-the-guard, Hans Schultz.
