Tobruk (movie, 1967)

In September 1942, the German Afrika Korps under Rommel have successfully pushed the Allies back into Egypt. A counter-attack is planned, for which the fuel dumps at Tobruk are a critical impediment. In order to aid the attack, a group of British commandos and German Jews make their way undercover through 800 miles of desert, to destroy the fuel dumps starving the Germans of fuel.
