When Italy entered World War II joining with the Axis powers (10 June 1940), Admiral Tur was Naval Commander in Durres, Albania. In October 1940 he was promoted to full Admiral and received the command of Special Naval Force ("Forza Navale Speciale", FNS) a unit specifically created for amphibious operations. FNS was composed of the light cruisers "Bari" and "Taranto", the destroyers "Carlo Mirabello" and "Augusto Riboty", the torpedo boats "Antares", "Altair", "Arethusa", "Andromeda", "Angelo Bassini", "Nicola Fabrizi" and "Giacomo Medici" and the landing ships "Sesia", "Tirso" and "Garigliano"; its initial task would be the invasion and occupation of the Greek island of Corfu, scheduled for 28 October 1940, coinciding with the start of Italy's invasion of Greece Bad weather, however, delayed the operation, until the poor results of the ground operations in Greece led to cancellation of the Corfu landing in order to divert the troops to the Greek-Albanian front.
