Viribus Unitis sinking 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. Overnight, an Italian sabotage team from a nearby patrol boat, who had not heard of the new State's creation and non-belligerence, penetrated the harbour and laid two 200 kg mines under the ready to explode at 6:30 sharp. The two-man team was captured and taken aboard Viribus Unitis, where they informed Vuković of what they had done. Vuković arranged for the prisoners (Raffaele Paolucci and Raffaele Rossetti) to be taken safely to the sister ship , and ordered the evacuation of the ship. But the explosion did not happen at 6:30 and Vukovic returned to the ship with many sailors. He therefore remained on his ship and went down with her and 300-400 of her crew when the mines exploded shortly afterwards at 6:44. Vuković
