On the night of 19 July, the four bands crossed the border. They went a secure route which had been put forward by Trbić and Anđelko. They did not rush, and spent days in Kozjak and villages of the Pčinja. They went fast and lightly in the night, and carefully descended towards the Vardar transition. In the village of Živinj, in the middle of the junction, they encountered Bulgarian Voivode Bobev; the meeting at first was sudden and unpleasant, but quickly became friendly and festive. Voivode Bobev assured them that he was happy that they would fight together, and took the bands to the village of Lisičja, where they would cross over the Vardar. Only Sokolović suspected a fraud, but went reluctantly. A sudden Ottoman chase urged them to abandon the route on the river coast of Pčinja, and to cross Vardar at one of its confluences, as they had intended at first. On the night of 31 July, in the village of Lisičja, to no avail, a large Bulgarian ambush waited for Bobev to lead the Serbs to their hands - to terminate the Serbian Chetnik Movement.
