How in hell are we supposed to get through their defenses now?" While warning Craig not to let personal differences of opinion interfere with the operation, Colonel Harker also reveals that he was the genius with perfect hindsight who convinced Staff to approve Craig's original plan which would now be "maximum effort, land, sea and air". On the way, they encounter a patrol of Italian tanks, which stops a short distance from where they are resting in a gully. Later that night, Sergeant Major Jack Tyne (Jack Watson) spots a tank column approaching from the opposite direction. After Bergman and three of his men kill the Italian sentries, Colonel Harker, surmising that the approaching column "must be German -- the Italians are too fond of comfort to travel this late", tricks the two units into attacking each other by firing mortars, first at the Germans and then the Italians, enabling the raiders to sneak away. To avoid detection the next day, Craig safely guides them through a German mine field, before they are attacked by a British Curtiss P-40 Warhawk fighter. They manage to shoot it down, but eight men are killed and one troop transport truck, their auxiliary fuel supply, and both of their radios are destroyed. The fighting attracts Tuareg tribesmen, who are friendly with the Germans. Craig, who speaks their language, exchanges some guns and ammunition for two prisoners. The prisoners turn out to be British traitors Henry Portman (Liam Redmond), who has an Irish accent, and his daughter Cheryl (Heidy Hunt), who were shot down while flying from Benghazi to Cairo. They have papers signed by the Grand Mufti of Jerusalem (Mohammad Amin al-Husayni) and German Field Marshal Albert Kesselring: an agreement for "a group of important" Egyptian army officers to rise up against the British in a "holy war." The belief of the Germans is with Egypt conquered other Arab states such as Turkey will then side with the Axis; Cheryl Portman states that the Turks could put four million men into the war against the Soviet Union. That night, the Portmans are told by a mysterious SIG member about the British masquerade and where to find a gun and a map to an underground telephone cable nearby where they can contact German command in Tobruk and alert them to the British column and upcoming attack. When they reach the telephone, however, they are spotted by an Italian patrol. Henry Portman fires at the patrol and is killed, while his daughter is seriously wounded.
