Negotiations in the Balkans in early 1941

The aim of British negotiators was to build a coalition in the Balkans to oppose the Germans, particularly. The Yugoslav government was being pressured by Germany to join the Axis side. The British minister in Yugoslavia thought that if the Prince Regent, Prince Paul, knew how much aid the British were supplying to Greece that he would choose to join the Allies. In response to that input from Mr. Campbell, Anthony Eden wrote a letter to Prince Paul, telling him an outline of Greek and British plans. He suggested that how well Salonika could be defended depended largely on the Yugoslavs. He invited Yugoslav officers to Athens to coordinate plans. This is based on the account in Vol.II of the Official History.
