sentences:  Trifunović-Birčanin met with Roatta on 10 and 21 September and urged him to undertake this operation as soon as possible to clear the Partisans from the Prozor–Livno area and offered 7,500 Chetniks as aid on the condition they be given the necessary arms and supplies.He was successful in obtaining some arms and promises of action.The proposed operation, faced with opposition from Pavelić and a cautious Italian high command, was nearly cancelled, but after Jevđević and Trifunović-Birčanin promised to cooperate with Croat and Muslim anti-Partisan units, it went ahead, with less Chetnik involvement.
