On October 29, 1918 the National Council of Slovenes, Croats and Serbs broke off all relations with Austria and Hungary, establishing the new State of Slovenes, Croats and Serbs. Subsequently, Emperor Charles I gave the entire Austro-Hungarian Navy, merchant fleet, and all its installations to the new state. When representatives of the National Council arrived at the naval base at Pula on October 31, the commander in chief, Admiral Miklós Horthy, asked to whom he should hand over command of the fleet. The representatives had not considered the matter, and after some discussion accepted Horthy's suggestion of Vuković, who was promoted to rear-admiral and made commander in chief of the new country's navy when Horthy's flag was lowered at 5 pm.
