During World War II, Pećanac collaborated with both the German military administration and their puppet government in the German-occupied territory of Serbia.

As a subject of Austria-Hungary at the turn of the twentieth century, he was called to serve in the army but later his conscience would not allow him to continue because it went against his patriotic feelings as a Serb. He deserted and fled to Serbia where he entered the Serbian army with the rank of sergeant. From the year 1904, he was a Chetnik in the company of Đorđe Ristić-Skopljance, Vanđel Skopljanče, Rista Starački, and Vojislav Tankosić.

Emilio Milutinović, who survived the slaughter with Trbič and a couple of his men, was so grieved that he resigned from further guerrilla action. Later, however, he went on to participate in both Balkan Wars and the Great War as a Chetnik volunteer.
