 By April, difficulties had arisen between Mihailović's delegates and civilian Chetnik leaders like Đujić, to the extent that Mihailović's delegate told Đujić to avoid interaction with the Italians unless Mihailović had given prior approval.Despite these orders, Mihailović's delegates never achieved control of all of the civilian Chetnik leaders like Đujić.In late May, Đujić and the other long-term civilian collaborationist Chetnik leaders in the region suffered a severe setback when the Italian leader Benito Mussolini acquiesced to German demands and ordered the commander of the Italian Second Army, "Generale di Corpo d'Armata" (Lieutenant General) Mario Robotti, to coordinate with the Germans in the disarming of Chetnik detachments.
