 It was a continuation of the British Government policy of support and supply that started with the Maclean Mission and culminated in Tito's meeting with Winston Churchill in Naples in August 1943.As Allied troops from the East and West were moving towards Berlin, they realised that large German military formations such as Army Group E will eventually abandon Greece, Albania and Yugoslavia and withdraw to defence lines further north.This would reinvigorate and resupply their troops in the region and likely extend the war.
