In April 1942 a map titled "The Danube area" was published in Germany, where the so-called "new annexed territories" of Bulgaria in Vardar and Greek Macedonia and Western Thrace were described as "territories under temporary Bulgarian administration". This was a failure for Sofia's official propaganda, which claimed to have completed the National unification of the Bulgarians and showed the internal contradiction among Italy, Bulgaria and Germany. With the ongoing war, new anti-fascist partisan units were constantly formed and in 1942 a total of nine small partisan detachments were active in Vardar Macedonia and had maintained control of mountainous territories around Prilep, Skopje, Kruševo and Veles. The clash between the Yugoslav and Bulgarian Communists about possession over North Macedonia was not ended. While the Bulgarian Communists avoided organizing mass armed uprising against the Bulgarian authorities, the Yugoslav Communists insisted that no liberation could be achieved without an armed revolt. With the help of the Comintern and of Joseph Stalin himself a decision was taken and the Macedonian Communists were attached to CPY. Because of the unwillingness of local Communists for earnest struggle against the Bulgarian Army, the Supreme Staff of CPY took measurements for strengthening of the campaign.
