When did Serbia accept annexation of Bosnia ?
Schutzkorps , predominantly recruited among the Muslim ( Bosniak ) population , were tasked with hunting down rebel Serbs ( the " Chetniks " and " Komiti " ) and became known for their persecution of Serbs particularly in Serb populated areas of eastern Bosnia , where they partly retaliated against Serbian Chetniks who in fall 1914 had carried out attacks against the Muslim population in the area .
