reported that "about 2,000 souls" were "killed by the Chetniks in Croat and Muslim villages of Prozor, Konjic, and Vakuf" and "the districts of Prozor and Konjic have hundreds of slaughtered and murdered women and children as well as burnt houses." Another 200 Croats and Muslims were killed in the Mostar area, just prior to the massacres in Prozor. In the same month, over 100 inhabitants of the village of Gata near Split were massacred by the Chetniks of Mane Rokvić, and many houses were burned. Two days later, more massacres were carried out in the Dalmatian Hinterland. On 4 and 5 October 1942, Chetniks (supported by nearby Italian forces) killed 120 Croat civilians (mostly elderly, women and children) in Dugopolje and neighbouring settlements. Victims of these massacres were sadistically tortured and killed; burning people alive in buildings that had been set on fire, gouging out the eyes, smashing open skulls and cutting out people's hearts with knives. The local committee of the Communist Party of Croatia for Central Dalmatia reported on October 4, 1942: Ismet Popovac, the former mayor of Konjic, held that Muslim population should cooperate with the Chetniks against the Ustaše, as a way to protect themselves. He agreed with the Chetnik leadership to form a Muslim Chetnik militia. The Chetniks in eastern Herzegovina then concentrated their attacks on the Croat population. In November 1942, Popovac reported to Mihailović that, due to their cooperation in Herzegovina, "the Croat inhabitants, who were largely Ustasha-inclined, have been expelled. In that way, from Gabela to Mostar the entire left bank of the Neretva has been cleansed, and the number of refugees is estimated at 12,000 people." In accordance with the Chetniks' Greater Serbia ideology, in November 1942, Ostojić was encouraged by Mihailović to wage a campaign of terror against the Muslim population living along the borders of Montenegro and the Sandžak, and subsequently reported that Chetniks had destroyed 21 villages and killed about 1,300 people. Not long after this, the "March on Bosnia" offensive was planned for December 1942 as a campaign against the Partisans. Chetnik units in Montenegro were mobilized, but the offensive was postponed. Apart from attacking the Partisans, the offensive included a genocidal assault on the Muslim population. In January and February 1943, these units were given orders for "cleansing actions" against Muslims in Sandžak and in southeastern Bosnia. Chetnik Commander Pavle Đurišić, who led the operations,
