 On 1 July , an Italian armoured unit arrived in Gacko to reinforce the garrison . An Ustaše operation to clear the insurgents from the Stolac district began on 3 July , meeting with success and opening of the road from <unk> north to Odžak . The Ustaše did not go closer to Nevesinje as they were not in uniform , and were concerned that the Home Guards would mistake them for rebels . During this operation , three Ustaše were killed , including their commander , and the Ustaše fighters killed ten rebels and captured two . In the belongings of one of the captured rebels , the Ustaše located a report by the " National Movement for the Liberation of Nevesinje " ( <unk> @-@ Croatian : <unk> <unk> <unk> <unk> <unk> ) , which was apparently how the rebels referred to themselves . The report made it clear that the rebels were using military tactics and organisation , and hinted at co @-@ operation with the Italians . According to information gathered by the police , the local rebel leadership included former Mostar merchant <unk> <unk> , the <unk> brothers from Avtovac , the Orthodox priest Father <unk> from <unk> , and a Captain <unk> from Avtovac .
