Raid on Rommel (1971)

Captain Foster plans on raiding German-occupied Tobruk with hand-picked commandos, but a mix-up leaves him with a medical unit containing a Quaker conscientious objector. Despite all odds they succeed with their mission. On the way they pick up and drug the mistress of an Italian general, blow up the entire fuel supply for the Afrika Korps, and swap philatelic gossip with Field Marshal Erwin Rommel.
