Churchill received him in trademark fashion: in bed, wearing an embroidered dressing gown, smoking a cigar. He, Joseph Stalin, and Franklin D. Roosevelt had discussed the matter of Yugoslavia at a recent conference in Teheran, and had decided to give all possible support to the Partisans. This was the turning point. The Chetniks were given a task (a bridge to blow up) and a deadline, to show whether they could still be effective allies; they failed this test and supplies were re-directed from them to the Partisans. The British government was left with the tricky political and moral problem of King Peter and his royalist government in exile. But the main issues were air supplies and air support, and to help co-ordinate this, Maclean's mission was expanded. Some of the new officers included Andrew Maxwell of the Scots Guards, John Clarke of the 2nd Scots Guards, Geoffrey Kup, a gunnery expert, Hilary King, a signals officer, Johnny Tregida, and, for a time, Randolph Churchill. Some of these were SAS or otherwise known from the Western Desert Campaign the previous year.
