were aware the POWs were engaged in spying and sabotage; Crittendon replies that he would report them to the German authorities. Crittendon constantly tries to develop and attempt escapes; however, they ultimately fail due to poor planning. In later appearances, Crittendon is aware of Hogan's operations and participates in schemes, though he is shown to be amateurish, much to Hogan's annoyance. In the episode "Lady Chitterly's Lover," Fox played both Crittendon and British traitor Sir Charles Chitterly (possibly a parody of William Joyce, commonly known as Lord Haw-Haw), who stops at Stalag 13 with his wife Lady Leslie Chitterly (Anne Rogers) while on their way to visit Adolf Hitler, whom they consider a friend. Lookalike Crittendon is broken out of Stalag 16, and replaces Sir Charles. Marya (Nita Talbot) – Marya is a Russian White émigré spy whose work occasionally aligns with Hogan's. She often appears as the trusted paramour of a high-ranking German officer or scientist. Her mission is to either discredit them or set them up for arrest, as she notes that "...We cannot trust Hitler to shoot all his own generals". She meets Hogan and LeBeau in Paris during the second season, where she learns of their Stalag 13 activities. Her schemes often come into conflict with Hogan's, but her plans and Hogan's always turn out to be compatible. Marya constantly flirts with Hogan, to his discomfort, and also flirts with LeBeau. Infatuated, LeBeau trusts her and believes her to be someone who will never sell out to the Nazis, but Hogan is always wary of her and suspicious of her motives. Klink is also suspicious of Marya, stating that trouble always ensues when she visits Stalag 13. Oscar Schnitzer (portrayed by Walter Janowitz) - Schnitzer is an elderly veterinarian and dog trainer who keeps Stalag 13 supplied with guard dogs. He is a member of the German underground resistance, and secretly in league with Hogan and his men. Schnitzer's truck is occasionally used for smuggling people in and out of camp, as the guards are afraid of the dogs, and as such will not look inside the truck. Tiger (portrayed by Arlene Martel) – Tiger is a French Underground contact who has several encounters with Hogan. Hogan notes that Tiger has saved his life at least once; He describes her as 'the' leader of the French Underground. Hogan frees Tiger from the Gestapo twice: once on
