Tomo Milinović Tomo ( Đurov ) Milinović ; ( Serbian Cyrillic : Томо Милиновић ; Anglicised : Tomo Milinovich ) , ( 1770 – 1846 ) was a Duke serving under Karađorđe Petrović during the First Serbian Uprising against the Ottoman Empire , he was also Karađorđe ' s advisor and head of artillery in one of the greatest battles during the uprising , Battle of Deligrad . Origin and early life . Tomo Milinović was born in Morinj , Boka Kotorska , Venetian Republic ( today ' s Kotor municipality , Montenegro ) . He learned how to read and write from a deacon in Morinj , and that was all of the schooling he attended throughout his life . At a young age in order to make a living and help out his family he became a sailor like most of the men from this region . For more than ten years he was serving on different merchant ships locally and around Europe . During these voyages he managed to save money and gain trading knowledge so he decided to settle down and become a merchant in Trieste . Considering that there was certain amount of merchants from Boka Kotorska living in Trieste as well as other connections he established through his sailing years he found his place quickly in that environment and became quite successful in his business . He even managed to financially help the planning of the First Serbian Uprising through friendship and connections he had with Dositej Obradović and other Serbian patriots that either lived there or visited Trieste . Move to Serbia and Uprising . In 1809 , after the third occupation of Trieste by French during Napoleonic wars , most of Tomo ' s possession had been overtaken . Just around that time The First Serbian Uprising was getting more successful and also more popular between the Serbian people that lived abroad , so Tomo decided to leave Trieste with his wife and son and join the uprising . After arriving to Serbia he had been accepted by Karađorđe to be his advisor and artillery specialist since he already had some artillery experience while sailing on armed merchant vessels . After the Treaty of Bucharest was reached between Russians and Ottomans , few of the Russian gunsmiths assigned to Karađorđe by Russian Military left Serbia . Tomo offered himself to take over the job which Karađorđe gladly accepted . In 1813 Tomo created two cannons of the same size consisting of five pieces each weighing 35 kilograms which made them extremely useful because of the mobility . That same year Tomo was sent to defend Deligrad as a Head of Artillery , where the Serbian army , consisting of 30 , 000 troops defeated the Turkish army consisting of 55 , 000 troops . Under his command Artillery made a great effort in this battle by good positioning and frequent relocation of the cannons which caught the opposing army unprepared in multiple occasions . Exile . After the failure of First Serbian Uprising , Tomo moved back to Trieste where he stayed until 1815 . On Karađorđe ' s recommendation he moved to Russia , to the town called Akkerman , Bessarabia . While in exile Tomo wrote two books : Umotvorine and Istorija Slavenskog Primorja . " Umotvorine " has been published 1847 . in Belgrade , and republished 2004 . in Morinj after great effort made by one of the family descendants Jeremije Milinović . Unfortunatelly " Istorija Slavenskog Primorja " was lost and had never been published . Death . Tomo Milinović died in exile in 1846 . Without being aware of that fact one of his great friends Sima Milutinović made efforts and got approval from the Serbian government at the time to bring Tomo back to Serbia , which was Tomo ' s great wish , but unfortunately it was too late .
