S1·E28 The Double or Nothing Raid

Moffitt is about to be executed for "espionage against the Third Reich" when suddenly the Patrol comes to his rescue. A commandeered German truck unsuccessfully attempts to scoop up Moffitt, but manages to take a Nazi captain in his place--for exchange. Negotiations for a prisoner exchange are fruitful, but Troy doubts that the Germans will obey their own rules. Indeed, the Nazi's Colonel Voss wants to see the Patrol wiped out and uses the exchange as a trap. The captured captain tries to escape the Patrol and gets himself killed. Now Troy has no one to exchange for a seriously wounded Moffitt and must attempt to pass himself off as a German.
