Mihailović was the first to attempt to contact the Allies, and SOE despatched a party on 20 September 1941 under Major "Marko" Hudson. Hudson also encountered Tito's forces. Notable members of this party included Sir Christopher Lee. Through the royalist government in exile, SOE at first supported the Chetniks. Eventually, however, due to reports that the Chetniks were less effective and even collaborating with German and Italian forces on occasion, British support was redirected to the Partisans, even before the Tehran Conference in 1943.
