 Đujić was a principal organiser within the Kistanje camp, which held around 1,500 refugees, and from mid-July was recruiting them for the Chetnik cause.In August, once a general uprising against the Ustaše had begun, Đujić went to the centre of the revolt in Drvar with another Chetnik leader and sought approval from the leadership of the uprising to take leadership of the rebellion in the Knin region.Đujić then established his Chetniks around Knin and coordinated with Chetniks in the Bosansko Grahovo district.
