[7] Petar Smiljanić was titled as capo (principale),[8] and after arrival from Udbina to Dalmatia was included in the troops of commander Bosichi Renesi, and was noted for orderly holding his horse and weapons.
[6][5] First major intrusion into Turkish Croatia was in 1648 in the area of Unac, and soon Leonardo Foscolo named his commander of all forces in North Dalmatia.
[6] In July of the same year, he participated in the exhausting campaign led by count Frane Posedarski against fort Ribnik in Lika, where he died alongside Stipan Sorić.
He participated with c. 250-350 Morlachs (Uskoks) from Ravni Kotari in the conflict near Zečevo, on 31 July 1648, where died renowned Vuk Mandušić.
[14] At the end of summer 1686, Smoljan Smiljanić and Stojan Janković went on a big raid in the countryside of Livno due to rumours of vast Ottoman troops invasion, led by pasha Bastić and Ali-beg Filipović, with the intention to rebuild the land and fortifications.
In the raid many houses and goods vanished, also there were many human casualties, with Janković and Smiljanić noting on 7 September that the whole valley of Livno within 50 miles (80.4 km) became desolated.
[5][2] Petar and Ilija Smiljanić were characters in Croatian epic poetry and were mentioned by Andrija Kačić Miošić in his poem Od vitezova dalmatinskih:[20] I pogibe Petre Smiljaniću Na Krajini od Udbinom gradom: Pogubi ga junak od Krajine, Po imenu Ograšević Mujo ... Pogibe nam na glasu delija Po imenu Smiljanić Ilija, Na Vučjaku ispod Velebita: Pogubi ga Markić Radojica, Koga trikrat vadi iz galije, A četvrti s tanani višala.
