Two missions subsequently dropped "blind" i.e. without prior arrangement for a reception party, failed. So too did an attempt by Basil Davidson to incite a partisan movement in Hungary, after he made his way there from northeastern Yugoslavia. Greece Greece was overrun by the Axis after a desperate defence lasting several months. In the aftermath, SIS and another intelligence organisation, SIME, discouraged attempts at sabotage or resistance as this might imperil relations with Turkey, although SOE maintained contacts with resistance groups in Crete. When an agent, "Odysseus", a former tobacco-smuggler, attempted to contact potential resistance groups in Greece, he reported that no group was prepared to co-operate with the monarchist government in exile in Cairo. In late 1942, at the army's instigation, SOE mounted its first operation, codenamed Operation Harling, into Greece in an attempt to disrupt the railway which was being used to move materials to the German Panzer Army Africa. A party under Colonel (later Brigadier) Eddie Myers, assisted by Christopher Woodhouse, was parachuted into Greece and discovered two guerrilla groups operating in the mountains: the pro-Communist ELAS and the republican EDES. On 25 November 1942, Myers's party blew up one of the spans of the railway viaduct at Gorgopotamos, supported by 150 Greek partisans from these two organisations who engaged Italians guarding the viaduct. This cut the railway linking Thessaloniki with Athens and Piraeus. Relations between the resistance groups and the British soured. When the British needed once again to disrupt the railway across Greece as part of the deception operations preceding Operation Husky, the Allied invasion of Sicily, the resistance groups refused to take part, rightly fearing German reprisals against civilians. Instead, a six-man commando party from the British and New Zealand armies, led by New Zealander Lieutenant Colonel Cecil Edward Barnes, a civil engineer, carried out the destruction of the Asopos viaduct on 21 June 1943. Two attempts by Mike Cumberlege to make the Corinth Canal unnavigable ended in failure. EDES received most aid from SOE, but ELAS secured many weapons when Italy collapsed and Italian military forces in Greece dissolved. ELAS and EDES fought a vicious civil war in 1943 until SOE brokered an uneasy armistice (the Plaka agreement). A lesser known, but important function of the SOE in Greece was to inform the Cairo headquarters of the movement of the German military aircraft that were serviced and repaired at the two former Greek
