Pavle Đurišić, outlined the Chetnik goals: While the document's origin and its connection with Mihailović is disputed, it shows how the basic goal of the Chetniks was to be achieved. A March 1942 document from the Chetnik Dinara Division, active in northern Dalmatia, closely followed the December 1941 memorandum. The document called for the creation of a Greater Serbia with an exclusively Serb population, and the cleansing of Dalmatia, Lika, Bosnia, and Herzegovina of Croats and Muslims. In a letter from May 1942, Vasić hailed Moljević's writing as a very interesting idea. Vasić argued that "the question of a homogeneous Serbia, which will have to include all areas in which Serbs live today, is beyond discussion." He noted that the Chetniks lacked the strength to carry out the planned ethnic cleansing during the war, and concluded that it should be done in the years following the war's end: "Consequently, if we are wise, this question of cleansing or resettling and exchanging of populations will not be that difficult." Mihailović's diary from spring 1942 reads: "The Muslim population has through its behaviour arrived at the situation where our people no longer wish to have them in our midst. It is necessary already now to prepare their exodus to Turkey or anywhere else outside our borders." A Chetnik manual from December 1942 discussed the "revenge" against Croats at the end of the war and in its aftermath: "One should not fear that the retribution executed in this manner would not be complete as far as the number of executed is concerned. If there are not more, then there are at least as many Frankovci and members of a certain intelligentsia, as there were Serbs who were killed." A 13 February 1943 letter from the commander of the Ozren Chetnik Corps, sent to the commander of the Zenica Chetnik detachment, referred to the December 1941 instructions: Summer 1941 uprisings In June 1941, the Serbs started an uprising in eastern Herzegovina against the NDH, provoked by large-scale massacres perpetrated by the Ustashas. More uprisings followed during summer in parts of the NDH. Serb rebels in these revolts were in the first months a mixture of Communists and their sympathizers, and Serb nationalist groups. The leaders of those groups, among whom were former politicians, former officers of the Yugoslav Army, and Orthodox priests, were affiliated to pre-war nationalist organizations or local subcommittees of the Chetnik
