The Austro-Hungarian government thus decided to hand over the bulk of its fleet to the State of Slovenes, Croats and Serbs without a shot being fired. This was considered preferential to handing the fleet to the Allies, as the new state had declared its neutrality. Furthermore, the newly formed state had also not yet publicly dethroned Emperor Karl I, keeping the possibility of reforming the Empire into a triple monarchy alive. The transfer to the State of Slovenes, Croats and Serbs began on the morning of 31 October, with Horthy meeting representatives from the South Slav nationalities aboard his flagship, "Viribus Unitis". After "short and cool" negotiations, the arrangements were settled and the handover was completed that afternoon. The Austro-Hungarian Naval Ensign was struck from "Viribus Unitis", and was followed by the remaining ships in the harbor. After the transfer, Horthy took with him from his personal cabin a portrait of Emperor Franz Joseph I, which the late Emperor had gifted to the battleship, along with the ceremonial silk ensign of "Viribus Unitis", and Horthy's own personal admiral's flag. That evening "Viribus Unitis" was renamed "Jugoslavija". Control over the battleship, and the head of the newly-established navy for the State of Slovenes, Croats and Serbs, fell to Captain Janko Vuković, who was raised to the rank of admiral and took over Horthy's old responsibilities as Commander-in-Chief of the Fleet.
