As a birthday present to Col. Hogan, his men take it upon themselves to blow up an ammunitions dump. Unfortunately, they target the wrong location, thanks to false information fed to them by the Gestapo. Hogan must set things right without tipping off the Gestapo -- and make it back to camp in time to blow out the candles on his oversized cake. Written by Arthur Julian, "Happy Birthday, Dear Hogan" originally aired on March 22, 1969, as the final episode of Hogan's Heroes' fourth season. ~ Hal Erickson, Rovi
