All these activities have contributed his stay in Veles to be very dangerous for his life so in September 1942 he became a member of the Partisan Detachment Dimitar Vlahov. The detachment has 3 bands and Blagoj was political commissar of the Second band. He was very brave when there was battle and in the villages where they were going he was speaking to the villagers and he organized meetings where he was calling the local people to expel the occupiers fighting against them. In December 1942, the Bulgarian occupiers started to work on decomposition of the detachment. One of that was the separation of the detachment near Zelenikovo. Blagoj with one group of partisans had to go to Black Mountain of Skopje (Skopska Crna Gora) but because of the snow which there was plenty of it, they had to come back in the town. They were hiding in the town for a while because they were unable to contact the people from the party. After that they went to Rosoman where they have been seen and they were caught and taken to Veles military barracks. There they were tortured very badly. They were asking him everything but Blagoj didn't answer anything. On 13 January 1943, Blagoj only said that the partisans would win the war. When the Bulgarian occupiers heard this they were very angry so the cut him alive on pieces and buried him alive.
