Bari in Southern Italy, from which they operated their networks and agents in the Balkans. This organisation had the codename "Force 133". This later became "Force 266", reserving 133 for operations run from Cairo rather than the heel of Italy. Flights from Brindisi were run to the Balkans and Poland, particularly once control had been wrested from SOE's Cairo headquarters and was exercised directly by Gubbins. SOE established a new packing station for the parachute containers close to Brindisi Air base, along the lines of those created at Saffron Walden. This was ME 54, a factory employing hundreds, the American (OSS) side of which was known as "Paradise Camp". Yugoslavia 1941, SOE helped considerably in anti-Axis propaganda and in preparing the Yugoslav coup d'état which overthrew the pro-Axis regent, Prince Paul. After the pro-British coup succeeded, the Axis Invasion of Yugoslavia ensued. In the aftermath of the German invasion and the Yugoslav capitulation, the Kingdom of Yugoslavia fragmented. Croatia had a substantial pro-Axis movement, the Ustaše. In Croatia and the remainder of Yugoslavia, two resistance movements formed: the royalist Chetniks under Draža Mihailović, and the Communist Partisans under Josip Broz Tito. 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 actor 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. Although relations were often touchy throughout the war, it can be argued that SOE's unstinting support was a factor in Yugoslavia's maintaining a neutral stance during the Cold War. However, accounts vary dramatically between all historical works on the "Chetnik controversy". Hungary SOE was unable to establish links or contacts in Hungary before the regime of Miklós Horthy aligned itself with the Axis Powers. Distance and lack of such contacts prevented any effort being made by SOE until the Hungarians themselves dispatched a diplomat (László Veress) in a clandestine attempt to contact the Western Allies. SOE facilitated his return, with some radio sets. Before the Allied governments could agree terms, Hungary was placed under German military occupation and Veress was forced to flee the country.
