The Croatian negotiators with the Allies were Tomo Jančiković, Zenon Adamić and Ivan Babić. The British always had a separate meeting with them. The HSS thought that their emissaries had been successful in securing the Dalmatian invasion plan. The appointment of Ivan Šubašić as the Prime Minister of Yugoslavia in exile, as well as General Ivan Tomašević's offer to put his army under Allied command once the invasion began, further encouraged the plotters. Finally, the Romanian coup and the advance of the Soviet troops led them to believe that the Allies would soon invade Dalmatia.
