When World War I began, after unsuccessfully attempting to join a number of other European armies, he enlisted in the Ottoman Army and was assigned to the Caucasus Front, where he reached the rank of major. He led gendarmerie troops during the siege of Van, but asked to be relieved due to what he believed were "unjustified massacres of Christians".
