The first formal agreement between Bosnian Chetniks and the Ustaše was concluded on 28 May 1942, in which Chetnik leaders expressed their loyalty as "citizens of the Independent State of Croatia" both to the state and its Poglavnik (Ante Pavelić). During the next three weeks, three additional agreements were signed, covering a large part of the area of Bosnia (along with the Chetnik detachments within it). By the provision of these agreements, the Chetniks were to cease hostilities against the Ustaše state, and the Ustaše would establish regular administration in these areas. The main provision, Article 5 of the agreement, states as follows:As long as there is danger from the Partisan armed bands, the Chetnik formations will cooperate voluntarily with the Croatian military in fighting and destroying the Partisans and in those operations they will be under the overall command of the Croatian armed forces. ... Chetnik formations may engage in operations against the Partisans on their own, but this they will have to report, on time, to the Croatian military commanders.
