 This is also the period in which we can find Croats as high-ranking officers, like admiral Maximilian Njegovan (Commander-in-Chief of the Navy, 1917–1918) or admiral Janko Vuković (commander of SMS "Viribus Unitis").After the end of World War I, in 1918 the Austro-Hungarian navy on the admiral ship SMS "Viribus Unitis" in Pula was forced, under order of the Emperor Charles I of Austria, to surrender to delegates of the National Council of Slovenes, Croats and Serbs from Zagreb - Ante Tresić Pavičić, Vilim Bukšeg and Ivan Čop and members of the Local National Council in Pula.The Croatian flag was flown then.
