Career
He participated in the Cretan War (1645-1669), alongside Ilija Smiljanić, as the supreme commanders of the Venetian Morlach troops, of which he is enumerated in Serb epic poetry (as Janko of Kotari, Јанко од Котара). Janko was the son of Mitar, who hailed from Žegar. The Mitrović resettled, together with others from Žegar, in Budim near Posedarje, then under Venetian control.
Stojan, who was Janko"s eldest son, began fighting alongside him and Ilija Smiljanić early on, in the Cretan War (1645-1669).
Ilija, as the more experienced, was named serdar in 1648 after his father, serdar Petar Smiljanić had died. In February 1659, at the Cetina river, both leaders Janko and Ilija Smiljanić succumb to wounds after battling the Turks.
The same year, the well experienced 23-year-old Stojan is chosen as leader by the band. As leader, he constantly takes part in battles in the Frontier.
He was known to have defeated several Turkish contingents, and even himself slew the commanders, among which are notable: Ali-beg Durakbegović, Redžep-aga Filipović, aga Velagić, aga Pajalitović and Ibrahim-aga Kovačević.
Yugoslav writers Boško and Vladan Desnica are descendants of Stojan"s youngest brother Zaviša.
