Yugoslavia, Resistance

British officers are dropped to rendezvous with Tito's Partisan forces in Montenegro near Mount Durmitor. For some time the SOE, Special Operations Executive, have been receiving reports that Gen Draza Mihailovic and his Chetniks are cooperating with the Germans, but only now are they able to contact Tito and the real resistance. Tito's forces are in trouble at this time. They are hemmed in by superior German, Italian and Bulgarian forces and have been under attack for 10 days but are beginning now to concentrate their force in preparation for fighting their way out. One reason for this slowness has been the desire to keep the appointment with the British.
