In early February 1943, Đujić and fellow Chetnik leader Petar Baćović tried to participate in the Axis Case White offensive against the Partisans but the Germans stopped them from getting involved. On 10 February, Đujić, Ilija Mihić, Baćović and Radovan Ivanišević, the Chetnik commanders of east Bosnia, Herzegovina, Dalmatia, and Lika, signed a joint proclamation declaring to the "people of Bosnia, Lika, and Dalmatia" that "since we have cleansed Serbia, Montenegro, and Herzegovina, we have come to help to crush the pitiful remnants of the Communist international, criminal band of Tito, Moša Pijade, Levi Vajnert and other paid Jews". The Partisan rank and file was called upon to "kill the political commissars and join our ranks right away," like the "hundreds and hundreds who are surrendering every day, conscious that they have been betrayed and swindled by the Communist Jews." By 17 February, it was clear that the Chetniks in western Bosnia, including Đujić's Dinara Division, had failed to use Case White to recapture Drvar and unite the Chetnik forces in the Dinaric Alps and western Bosnia.
