The Allies would like to locate the new Luftwaffe headquarters of famed WWI German flying ace General Von Richter (Henry Corden), aka "the Blue Baron." To realize this goal, Hogan persuades Klink to throw a gala party in Von Richter's honor. Cynthia Lynn, who played Klink's secretary Hilda during the series' first season, is here cast as a Mata Hari-like exotic dancer, while frequent Hogan's Heroes supporting player Celeste Yarnall plays a nanny. Written by Arthur Julian, "Will the Blue Baron Strike Again?" originally aired on December 14, 1968. ~ Hal Erickson, Rovi
