For some time, Regent Alexander and officers loyal to him had planned to get rid of the military clique headed by Apis, as Apis represented a political threat to Alexander's power. The Austro-Hungarian peace demand gave added impetus to this plan. On 15 March 1917 Apis and the officers loyal to him were indicted, on various false charges unrelated to Sarajevo (the case was retried before the Supreme Court of Serbia in 1953 and all defendants were exonerated), by Serbian Court Martial on the French-controlled Salonika front. On 23 May Apis and eight of his associates were sentenced to death; two others were sentenced to 15 years in prison. One defendant died during the trial and the charges against him were dropped. The Serbian High Court reduced the number of death sentences to seven. Regent Alexander commuted four of the remaining death sentences, leaving just three death sentences in place.
