The Holy War Raid - S1.E23

Using a fake (German) Rat Patrol, Dietrich abducts an Arab holy man that he will then "rescue" so that the Arabs will give their help to the Germans. The real Patrol is captured by the Arabs, though, and when they convince the Arab leader--who is a friend of Moffitt's--that they aren't guilty, Troy and Moffitt go to find the holy man. To do so means a horse trip across the desert.
