At the beginning of the World War II Perišić was a priest of the Serbian Orthodox Church in Kazanci, Gacko, Eastern Herzegovina. When population of Eastern Herzegovina was subjected to genocide carried by Independent State of Croatia, Perišić inspired the local population to start a rebellion and defend themselves. Perišić commanded rebel units from villages Kazanci, Golija, Vratkovići and Dobrelji. On 6 June Perišić led the insurgents from his village during the attack on local gendarmes. Since Perišić and Milorad Popović had a significant influence on population in part of Gacko county, while captain Bajagić on part of villages near border toward Montenegro, the rebels entrusted them to lead attack on Ustaše position in Avtovac and Fazlagića Kula on 28 June 1941. During the preparation for the attack on Avtovac, Gacko and Fazlagića Kula, Perišić sent a letter to Dramešina. Avtovac, defended by 200 Croatian Home Guard, 50 Ustaše from Eastern Herzegovina and 20 Ustaše from Western Herzegovina, was attacked in dawn of 28 June 1941. Perišič was a leader of nationalist rebels, together with Manja Višnjić. The nationalist rebels established a battalion in November 1941, when communist also established their battalion. According to post-war sources published in communist governed Yugoslavia, Perišić met with Radoje Dakić and other members of headquarters of the communist detachment and agreed to cooperate in the struggle against Italian occupiers and Ustaše in Gatac county. Perišić was one of main organizers of gathering of the people of Gacko and Piva held on Ravno on 18 July 1941. According to Chetnik sources Perišić was awarded with Order of the Star of Karađorđe and promoted to the rank of voivode.
In January 1942, the Partisans captured Boško Todorović, the commander and delegate of the Chetnik leader Draža Mihailović in eastern Bosnia, in the village of Vrba, near Gacko. He was captured together with nine other Chetniks, including Captain Radojica Rončević and Vidak Kovačević. The Partisans and their captives headed toward Partisan Montenegrin HQ in Nikšić, but they were intercepted by Chetniks commanded by the priest Perišić who released Bošković and arrested the Partisans. Against the order of Bošković, the Partisans were released. Perišić was commander of the Gacko Brigade when he was killed together with 24 of his men in a battle with Ustaše in April 1945 during the Battle of Lijevče polje.
Legacy
The communist historiography intentionally ignored pre-22 June rebels in Eastern Herzegovina and Sanski Most because they occurred in the period of collaboration between communists and fascists, so it would contradict the communist narrative about rebels being led by communists. On the other hand, the first Partisan battalion established in Gacko at the end of 1941 was named "6th June" in honor of the first date of the uprising. In period after the Fall of the Berlin Wall Gacko municipality proclaimed 6 June as their holiday in honor of the beginning of the uprising and held public ceremonies on 6 June as the Day of Gacko.
